How To Start the APU of a Gulfstream G-IV - Pilot VLOG 36

[@sherriurquiola8624]

My wife and I enjoyed the video. We enjoy following you through your flights and adventures on the ground. Keep living that Corporate Pilot Life.

[@jimjohnson9237]

It’s all coming back to me now!

[@stevenphamm]

Great video Appreciate the thorough walk-thru and explanations Current SPIFR helicopter pilot working toward my fixed wing PPL then commercial rating

[@timothysiverly4128]

Side note on a gIV you can run engines with the cowling down on right side the apu won’t melt it. It’s the g450 550 and 650 that you need to worry about and there is an indicator on the over head on those that will illuminate if the right engine cowling is down

[@arshadrana1572]

Excellent video--just some clarifications-- APU cannot be just refered as a generator or so, rather it's a small engine using aircraft fuel to provide Bleed Air and Electrical Powe while engines are not running As the name suggests, conditioned air means to cool the cabin while it's hot and to heat up while it's cold.. You can put the APU bleed on immediatelyvafter start, however it will come ON only after 2 min.

[@robertgelley6454]

I flew a lot of different corporate planes. Lear 60, Hawkers, Challengers, Boeings and a few others. My favorite was the Gulfstream G-IV. It flew like a big T-38. Thank you for the nostalgia... such a fun plane!

[@rickjohnson831]

These videos you guys make are such a gift to us. So interesting. I can't thank all of you enough for taking the time to do this.

[@terryfurrh666]

Really enjoyed that, so much fun watching you guys fly.

[@davisc1926]

Years ago, I used to do some design engineering work that involved using a G-IV APU (which is made by Honeywell if I remember correctly). I helped build a prototype military aircraft start cart in which I was responsible for the controls and had to interface with all the APU electrical signals to show correct RPM's and EGT on a panel I designed. I love your videos, keep it up!!

[@CorporatePilotLife]

That's awesome!! It is Honeywell. Thanks for all your work!

[@niceguy2171]

Really nice detailed and even paced breakdown of starting and operating the APU, and much appreciated. Would like a detailed one of the FMS system in the aircraft please.

[@zanda677]

I do like your flight-deck and how it's set out Shaun very nice, please keep those videos coming....

[@richardmartin7780]

Hi Sean, A visitor from the UK here. You're channel is a recent find and I've thoroughly enjoyed the videos you've made so far. I am extremely impressed with the high standard of professionalism the two of you show in the cockpit. Excellent CRM, situational awareness and flying skills. The two of you are a fantastic advert for the organisation you fly for and I would be very comfortable knowing the two of you were the cockpit crew on any flight I took. I doubt your passengers get to have much dealings with you directly, but I think if potential customers got to see you in action it could well sway them to use your organisation over others. I too would be interested in some more techincal stuff about the G-IV. Something about the autopilot, autothrottles and flight director would be of particular interest if you get the time. What would also be good would be a short video about Francine and her work. I would guess there's plenty of preparation work she needs to do before your passengers get to board the aircraft. Thank you to the three of you for sharing the corporate pilot life with us. One that is probably not as glamourous as we imagine on occasion! Best wishes.

[@CorporatePilotLife]

Thank you so much! Your kind words mean so much to us. Doing a technical video on the automation of the aircraft is definitely on our list of topics to cover. I really like your idea about doing a video on Francine's work...we will definitely do that. I hope you continue to enjoy the videos, and thank you again for the enthusiasm!

[@niceguy2171]

That is a GREAT idea, and would be a very popular video..also a real eye opener for some people who probably think she pops on board last minute and just takes care of passengers, not realizing she is a part of the crew too.

[@edlapinski341]

Brought back great memories for me!!!!!!!!!!!!!!!!!

[@lauleneke1352]

Great information which makes it so much easier to enjoy the video because of having some knowledge of the operation pilots go through. Thank You.

[@garycombs8467]

awesome job....keep em coming look forward to every video

[@tomm7301]

Although I’m a big fan of your in-flight videos (particularly the longer episodes), I’ve really enjoyed your features on the G4’s systems, avionics, and other features. Thank you!

[@guillaumetardieux1674]

Thanks a lot Shaun for this tech video, very informative !!! Keep doing it every once in a while, it helps me understand the overall procedure on operating an aircraft, especially for me as a non-pilot ! Currently, I'm trying to catch up on all your videos and I tell you what, I'm enjoying all of them a lot (especially your trips in my country (French Guiana and Dijon) and when you bumped on the Equador ... Lmao !!!) ... Keep up the good work and thanks a lot to you, Jon and Francine for sharing !!! Fly safe !

[@jameswikstrom4174]

The APU comes in handy when you are at an airport where they do not have a GPU. I would imagine that it is more of a convenience item during start-up than connecting to a GPU. Greg from Premier 1 Driver who I am a big fan of gave a presentation similar to your's on how to start the Premier's engines. He has no APU and must be connected to a GPU for start. He can start one engine and then the other immediately after. No waiting involved. He saw that as a positive. I believe you have to wait a short period of time after starting one engine and then the other. The way I see it, 'It is all good"! Love the G-IV and your videos!

[@CorporatePilotLife]

The G-IV actually uses air (not electrics) to start the engines, so no waiting between engine starts for us either. But the problem with that is we must have the APU up to start the engines, or have a huffer air cart. A GPU wont help get the engines going for us.

[@Texmalibu87]

Very informative! I hope you do more videos like this one.

[@bigd-1-channel514]

Excellent and well done.

[@newgtguy]

Really great content guys. Just discovered you. Subscribed now forever (bell clicked). :)

[@CorporatePilotLife]

Awesome! Thanks!

Just came across your channel, great videos!! Keep em coming

[@CorporatePilotLife]

Welcome!

[@Captnoatp]

Great video again Sean. The idea of having a technical or maybe an operational topic, once in a while, of the G4 just make your already very interesting videos even better. Happy New Year to all of you from Norway.

[@CorporatePilotLife]

Glad you enjoyed it...Happy New Year!

[@burt24pop]

Super glad I found your channel. The G IV is my favorite jet too. Good stuff bro

[@CorporatePilotLife]

Awesome! New video should be up later this week...

[@abrahamjimenez4758]

This is great ! What kind of APU Oil is used on GIV?

[@VLove-CFII]

Excellent presentation!

[@307Aviator]

Really cool guys! please keep 'em coming!

[@MattPouy]

I would be interested to see a preflight briefing, and a run through of all of the checklists through after departure checks! Love the channel guys, keep up the great work!

[@CorporatePilotLife]

We can definitely make that one happen!

[@Ripper13F1V]

love it, very concise, and interesting to see it come alive.

[@lucianosantucci108]

Nice walkthrough - good quality, In fact - good enough for online training videos.

[@gulfstreamdriver131]

Great explanation on the apu start Sean! Very cool of you to quickly attend to our requests on creating technical videos.....i was a fan of your videos before, now I just became a bigger fan of your channel. Keep up the good work and happy 2018! Safe flights.

[@CorporatePilotLife]

That's what I like to hear! Happy New Year!

[@FlyTJ]

What an excellent video!

[@randyporter3491]

Well, another great tutorial Shawn, thank you !

[@OrrTrigger013]

Well done Sean! Thanks

[@jrwarner579]

Thanks, ​Sean ..very informative Shout out to John!!

[@gordonhenwoodsr.5227]

very nice... Thanks for sharing.

[@twhdvm]

I really enjoy these videos and appreciate all the time and effort you put into making them. I’m curious as to what the small screen above the PFD on the co-pilot side is (as well is the series of buttons to the left of the screen) - I assume those are the navigation/autopilot mode indicators and control panel? I saw in one video that the control panel also includes buttons that operate the digital checklist. Once again, thank you.

[@CorporatePilotLife]

That's called the Display controller, and there is one on both sides as well. They control many functions including the checklist and PFD/MFD layout. I'm planning a Tech video on these for the near future.

[@twhdvm]

Corporate Pilot Life Thanks!

[@ddavidone6538]

Very cool! You must have been a good CFI

[@ericlipke9309]

What is the ‘nut cracker’, when you check landing gear? Thank You, great videos!! Keep up the good work.

[@CorporatePilotLife]

That's the Gulfstream term for a weight on wheel switch. I have a video showing it here: kzbin.info/www/bejne/gaesc6CJos1shaM

[@jimleon7894]

Very interesting and concise explanation.

[@542640104]

I want to see your preflight inspection & flight planning for G4

[@rickm7923]

New subscriber. Really enjoy the technical Vlogs. How did you get the assigned designator “Presidential 69”

[@CorporatePilotLife]

The management company is called Presidential Aviation, so they get the Flight ID for all their planes

[@garypecoraro8580]

can show and explain the trim levers on side of console and how they operate thank you Great JOB

[@CorporatePilotLife]

Absolutely. That is one of the highly asked questions...I'll definitely do that one very soon. Than s for the suggestion!

[@mtausaut]

Hey Sean, how about a tech video of the operation from inside and outside for the operation, securing and testing of the Main Cabin Door on the G-IV?

[@DavidSilva-2304]

Hey Sean, can you make a video of how you brief a SID, STAR & a approach? Thanks!

[@CorporatePilotLife]

That's a great idea...I'll see if I can get that going. Thanks!

[@danjams]

269WR is a 1999 airplane. I see some major upgrades in avionics, exterior paint and interior from when that was a new airplane.

[@mabrams8740]

Love the tech videos

[@mikeblackford994]

These tech vids are great!

[@Big.Ron1]

Nice video. Last apu I started and operated was in BAE 146. Maybe you could do a thrust reverse and nose wheel steering operation and limits video. Thank you. Be safe.

[@tammyedwards6121]

You guys are scary smart.

[@CorporatePilotLife]

I try telling my wife that...she just rolls her eyes at me.

[@tammyedwards6121]

Hahaha.....

[@brianmcgee115]

I think a lot of people get Flow vs checklist confused when dealing with turbo props and jets. Maybe you can discuss how you use flow and checklist when in the cockpit. Thank you!

[@CorporatePilotLife]

That's a great idea!

[@jerrykorman7770]

Excellent description of the APU sequence. Despite the onboard APU do you still need a cart?

[@CorporatePilotLife]

As long as the APU is working properly, we don't need a cart for anything...except the lavatory...HAHA!

[@jerrykorman7770]

Yuck, no doubt. I come from the King Air world, the PT6 is electric start. If the battery was even a bit weak, the ITT would spike so it was generally a good idea to do a cart start on at least one engine - left - and then a generator-assisted start on the right engine

[@320Scott]

New subscriber. Love your channel! How did you and John end up flying the G-IV? Would be interested in a brief video explaining your backgrounds and previous lying jobs. Thanks

[@CorporatePilotLife]

That is definitely on the way...

[@niceguy2171]

Pretty sure everyone of us has asked for that at some time or another, and he is working on it thankfully.

[@fritzhuszagh3022]

You discuss, after the apu is running, turning on the air which, in turn, caused the exhaust temp to rise. But what does "turning on the air" actually do to the apu, or to the airplane?

[@CorporatePilotLife]

This works the same on the APU as it does on the main engines. We are taking bleed air off of the compressor section of the turbine engine to provide high pressure air for the cabin pressurization system. The pneumatic system of the APU is restricted to ground use only, so basically this is just to heat or cool the interior of the airplane. The air coming out of the APU (or engine) is vey hot from being compressed, so it has to go through a PACK, or pneumatic air conditioning kit, before entering the cabin. I hope this answers your question. If not, let me know and I'll try again.

[@cessnadrummer]

So why does the exhaust temperature rise so much when you turn on the bleed air? I assume since you're diverting some of the air to the PACK for the cabin, you're not getting rid of the exhaust air as quickly which might cause a temperature rise. Keep up with the great videos!

[@terryfurrh666]

New subscriber, do you guys only charter?

[@gmfurnald9219]

Really appreciate your videos! Sometime, please show us how the G-IV ran off the runway at KBED. I recall it had to do with locked controls. Did Gulfstream come up with a fix so it doesn't happen again? Or is it still just a checklist item?

[@CorporatePilotLife]

I will definitely talk about that one on video...but it was a control lock issue. Gulfstream redesigned the control lock mechanism so that the power levers cannot move with the control lock on, but not all airplanes have had the mod completed yet. So yeah...still a checklist item.

[@gmfurnald9219]

I got my multi out of KBED years ago, later based my Duke there. My nephew is now a designated examiner and mentor pilot on Phenom 100 and CJ's out of BED. Writes for Turbine Pilot edition in AOPA.

[@examiner0078]

Hey Shawn is there ever a scenario where you would use the APU in flight? Thanks. Chip

[@CorporatePilotLife]

The G-IV is only allowed to use the APU for electrical power in flight, so the only time we would really use it is if we lost one of the alternators in flight.

[@JoshuaTetrick-y7y]

show how to service the APU oil

[@dantucker2579]

Nice Thorough Start! And your E inverter was working too! You guys have the -150?

[@CorporatePilotLife]

Yes indeed...makes a big difference for ground cooling on a hot day, also gets those engines turning a little better than the -100.

[@dantucker2579]

Agreed! -150 is a big improvement. Now if GAC and the FAA could only fix the APU firebox sealant. ✌🏻

[@dreamcometrue8140]

Hi sir .i have a question : When the press the apu fire warnings switch .we don’t ear the outside firebell

[@ericpitar]

So cool!!

[@cmay878]

I am not a pilot but when do you shut it down? After engine start before depature? And is it restarted prior to landing? Just wondering.

[@CorporatePilotLife]

Every airplane is different, but in the G-IV we shut it down before takeoff and start it after landing. It isn't allowed to be used in flight. In the hawker, we shut it down and start it in the air.

[@cmay878]

@@CorporatePilotLife thanks!

[@rr8753]

Enjoy your videos, who owns the plane(WR), why Presidential 69 when tail number is different your paychecks must be really be allot! How much time do you guys get off to be with your families.

[@CorporatePilotLife]

A private company owns the plane, but Presidential Aviation manages it. Time at home varies, sometimes weeks at a time. Other times we're gone for weeks.

[@jbagglesworth]

As someone who is about to get their first full type rating in a G300, do you have any advice before/during training? (I’m Currently SIC only)

[@bartofilms]

Your G4 is very advanced. Are you guys type-rated for other Gulfstream models?

[@CorporatePilotLife]

Unfortunately, no. The G-IV is the only Gulfstream type we have...sa far

[@ExtremeRecluse]

Also provides emergency power in case of a huge bird strike. Your plane is probably not as bouyant as an A-320

[@CorporatePilotLife]

True on both...

[@countrysideb5]

If on AC ground power and you start the APU, does it automatically switch the the APU generator and vice versa back to ground when connecting the ground power. Can you stop that from happening and remain on ground power, even with the APU running? Thanks.

[@marvincjr]

Awsome..thanks!

[@swarajsandhu]

I have a couple of questions: when do you need GPU to start the APU? Does the APU stay on once the main engines come on or you turn it off afterwards..? If you have multiple stops during a day do you guys leave the APU on before the next flight or its always a start from a cold and dark cockpit?

[@CorporatePilotLife]

The GPU would only be needed to start the APU if the main batteries were dead. I've never had this happen to me, but I know pilots who have been in this situation. Usually we will shut the APU once the engines are started. The exception to this is when it is very hot outside and the cabin needs the extra cooling from the APU. In this case we will leave the APU on until nearing the runway, then switch the air system over to the main engines. If we have less than an hour between flights, we will generally leave the APU running. If it's more than an hour, we will usually shut it down and start from dark.

[@swarajsandhu]

Corporate Pilot Life thanks for replying!! :)

[@anels9]

Where abouts are the wiper switches located?

[@CorporatePilotLife]

They're on the lower part of the overhead panel

[@kirkroumas9207]

Sean I recently retired and only live 20 miles from mci and mkc so if you guys ever get in to one of these hit me up I would love to meet you guys and I will take you to get some fantastic KC bbq

[@ferdinandfrancis9673]

How long is the start up procedure take, how long do you normally get to the jet before the passengers arrive, finally do you keep lots of fuel in the tank when the jet is not in use and is in the hangar.Thanks

[@CorporatePilotLife]

All great questions...the startup procedure only takes a few minutes, but there are many system checks and FMS procedures that have to be done before starting the engines. We usually arrive at the plane an hour before passengers to get everything done. If we had to, we could go from opening the door to starting the engines in less than 10 minutes though. As far as the fuel, we prefer to not have lots of fuel in the tanks while sitting around as it stresses the gear. So we typically have around 5,000 pounds in it.

[@robertgreene8951]

Good morning The you Alway Fly the Airplane on the right seat and why you don't switch to the left side just curious

[@CorporatePilotLife]

It is just easier to not have to always adjust the seat position, pedal position, move our headsets back and forth, etc...

[@beozzie690]

Do you ever switch seats.. PIC or always in the second position

[@CorporatePilotLife]

We keep our seats so we don't have to constantly move the headsets back and forth and change seat/rudder positions. When Jon is out sick or on vacation, I move to the left and have a contract guy in the right.

[@beozzie690]

Corporate Pilot Life sounds good.. just wondering how much PIC time do you get is all.. Or do you both switch off being pic

[@CorporatePilotLife]

We switch that one...I log PIC when I'm flying.

[@richardsoucy3082]

Do a video on the fmc 😀😀

[@CorporatePilotLife]

That one is on the list...give us a little time for that.

[@julestoro2005]

Explain the nutcracker again

[@kevf4993]

ok here's my question....who pays you guys and for the plane costs?

[@j.o.p.enforcementagency7931]

Hey sean!! Do u guys have to deice???

[@CorporatePilotLife]

We try to put it in the hangar to prevent having to deice, but sometimes that isn't an option. So yes, we do have to from time to time.

[@JR-jx9qm]

You could pass me the GIV pilot training manual?

[@jeffspungen5585]

I I never flew in a golf stream before

[@Jeffreykum]

How do you learn too fly the jet

[@CorporatePilotLife]

There are a few companies that specialize in that...Flight Safety and CAE are the biggest ones.

[@joeycarr1398]

Do you know of any G-IV addon for X-Plane Flight Sim ? How many flight hours do you need min. to Captain a G-IV?

[@CorporatePilotLife]

I'm sorry, but I can't help you out for the Flight Sim. As far as hours required to be Captain on a Part 91 Gulfstream, there really aren't any legal minimums. As long as a company will hire you, and an insurance company will cover you, you're good to go.

[@tedferkin]

+joe carr If you go to X-plan.org there are a bunch of aircraft there, including this wonderful specimen forums.x-plane.org/index.php?/files/file/37010-gulfstream-g-iv-sp-v11/ enjoy

[@danjams]

I'm wondering why your call sign is "Presidential 69" instead of Gulfstream 269WR

[@CorporatePilotLife]

It's the company name...

[@caca121112]

How do you manage the rest during the flight? lets supose you are having a 10 hours leg? any additional pilot is mandatory? regards from Brazil.

[@CorporatePilotLife]

That is a question with many answers. It all depends on whether we are flying the owners or if we are chartering the plane. With the owners, the law has no limit on flight time. On charter flights, we are restricted to 10 hours of flight time before we must start adding crew members. Before we make a long flight, we always try to get lots of rest so that we are alert for the entire flight.

[@ogc90]

Yea thats nice now where is the key to the booze cabinet !!!!!!

[@tylerlawing7845]

There is no key to the booze cabinet, open bar!!! You do however have to find the key that is hidden somewhere on the exterior of the plane to get inside first, of course.

[@56hueycobra]
