I took my 8 year old grandson on his first plane trip. Was telling him about the gears/tires going up and down. After seeing this video, he now understands. Thanks.

[@jimhal5553]

Just in case anybody noticed, or asked, the rubber ring sticking out from the sides of the nose tires is a debris deflector that prevents things like sand and dirt from being kicked up by the nose tires and sent it into the engines.

[@111477cheech]

Who are the three dopes who gave this a thumbs down...Pretty cool video.

[@LMays-cu2hp]

Thank you for showing the lading gear. That is nice when the aircraft is placed on jackets high enough to see the landing gear go up and down. Yes of the main lading gear the right does seem slow. But maintenance guys and now you know that the gear does operate faster in general. Yeah, we are to busy being inside of course. Thank you for showing this beautiful aircraft .

[@vetterfellow]

First time I've seen that, and I don't think I'll ever see that again. So thanks Shawn for tech Tuesday on Wednesday😁. Wheels - Up !!!.

[@abbasrizvi9389]

I am such a geek.....cant stop watching that. I thought it was one of the coolest videos!

[@mikeloughran5196]

Not sure why I was surprised by how noisy they are. Really like the tech Tuesday, thanks.

[@LukePylypciw]

When I opened this I said that’s one big hawker.. but then I hear “it’s on jacks”😂

[@davids4795]

Cool stuff!

[@brucebelitz3451]

Thanks for the video, always learning!

[@ILM787]

Always interesting...keep them coming!

[@chriholt]

Fascinating Shaun, thanks as always!

[@MJ-fh8fw]

Very cool to see...

Great video. Love your tech Tuesday

[@chqbr9061]

Thanks Shaun, Nice video!!

[@GusCarlson]

I love gear swing videos thanks Shaun!

[@kevincollins8014]

That is awesome to see up close what's actually going on. Thanks for sharing this!

[@StealthParrot]

That was so cool! Love geeking out on theses tech videos. Thanks Shaun.

[@shawndavis9349]

Very interesting - I really enjoy your tech Tuesday videos!!!

[@michaelloder5150]

AWSOME Shaun.....Great Video

[@donc9751]

Very interesting Shaun! I enjoy seeing the mechanical systems working.

[@timaz1066]

Thanks for the video Shaun! Keep up the Corporate Pilot Videos.

[@iisubzeroii5538]

Very Cool Thank you for sharing shaun

[@SmittySmithsonite]

Great stuff as always, Shaun! Pretty ingenious engineering in landing gear.

[@nojabformeeducateyourself3393]

Pretty cool to see how it works up close. Very Cool.

[@Pintuuuxo]

Very nice video Shaun. You can really imagine it happening during flight.

[@rchuyck]

Great video. Was amazed at how fast the nose gear extends!

[@aidandonegan731]

Cool video. Love the bsckground mule noise and the reassuring drop

[@uggahh430]

Thank You!

[@gtr1952]

Thanks Shaun, and thanks to the maintenance guys!! Never saw that up close before, very cool!! 8) --gary

[@WolfPilot]

Thanks for another awesome video! This one is just downright intriguing! I almost got to see this happen in person in the Monarch hanger at KTKI this year. I think it was a citation jet that was in annual. Keep these vids coming!

[@maxmasterson3804]

Crazy how fast that nose gear comes down! Seems like the door hinges would wear out ! Thanks for sharing!

[@ianlomaxphotography6978]

Great video Shaun. Like anything mechanical it needs looking after to keep it performing at its best. You look to have a great team and the willingness to show this sort of work to the world allows you to demonstrates a competent and safe operation which should win customers. Keep them coming. You can inspire the next generation of engineers and pilots😁

[@MattyCrayon]

Fascinating. Thanks for sharing. I didn’t expect the speed of the front gear and the snap of the doors as they closed 👍

[@john5321]

Thanks for the added bit about the engine driven hydraulics. So it is more of a functional check that the hydraulic systems are intact after maintenance and not leaking and perform a cycle correctly..might be interesting to see the gear down and locked switch (lol or the cost) and maybe another hawker going wheels up to compare. Love the tech tuesdays! Dinner on me for you and your crew if you ever make it to Hampton Roads area.

[@MrNice-gw5dt]

love the videos Sean!

[@markmorgan5892]

Yeah that was a freaking awesome video!!! I love seeing how all that stuff works. U never get to see it work when ur inside the plane, which is a good thing lol!!

[@dabuya]

I’m glad you explained the differences between the “mule” driving the hydraulics and the engines. I thought while watching this that the lag in the right side retracting could be a problem if an engine was lost on takeoff.

[@jerryrounds8586]

Very cool

[@keithallen917]

That was great, would love to see the gear open using emergency procedures.

[@Will-ol9lp]

That’s the first time up and close to see the landing gear work. That’s cool Thanks

[@mb8kr]

Sawesom, to see that up close,

[@Prestonelmer]

Dang, those doors close hard!

[@timothyosborn1697]

When I worked for Boeing, in the 747 Final Assembly Unit, in Everett, I couldn't pass watching the Gear Swing on a 747, or even 767 and 777, for that matter. All fascinating.

[@rikspector]

Shaun, The speed with which the nose wheel drops down is scary, even at the "slow " speed. Heck of a lot better than a potential belly landing:) Cheers, Rik Spector

[@moacyrjetpilot]

Certainly it drops even faster during flying as a result of air impacts and speed!

[@firstnamesecondname5341]

Wow 😁👍

[@ralphwoodard609]

Interesting one Sean. I’ve never seen it up close like that and thanks for showing us. On another note, what were the red flashing lights in the hanger up above in your video?

[@mikeh2520]

Hi Shaun. Thanks for showing this to us. I find it very interesting. I notice the asymmetry in the movement of the main gear. Can you feel that at all in the handling during that period? Also I noticed a small spoiler ahead of the flaps. Can that be deployed separately? Best regards and keep up the good work.

[@CNT12696]

Great video. Why does the nose gear move so quickly compared to the mains?

[@demerzel24]

Almost beautiful 😀. Do you have to apply the breaks before the gears are retracted or is that done automatically?

[@BeechSportBill]

Up down!

[@miguelbranco1604]

The pin from the activation / deactivation of the steering on the NLG leg is put from lower to up position? just a question from a fellow AME i do not have the type rate of the A/C, keep up the good work

[@larrymayberry2312]

As long as there are there green before landing all will be fine.

[@bruschi8148]

Can't imagine the nose gear going any faster..wow

[@WolfPilot]

LoL! Imagine a switchblade opening!

[@johnfarr2738]

Very interesting, does the nose wheel always come down before the main gears all the time?

[@randallvaughan7337]

Shaun, the tires looked new. Had they just been changed as part of the servicing?

[@patrickmorrissey8754]

I guess I am a Gear Head because I could watch this all day long. Thank you for taking the effort to show this. However what is the cabling right behind the nose gear opening? I think it runs the entire length of the underbelly. Patrick from Albuquerque

[@kittykat999a]

Can you show or talk about how the gear locks into the down position and won’t try to retract until you want it to? Beats dropping a plane on the ground. Thanks.

[@gkuhlen2294]

Is there any momentart change in handling when the right gear pauses before complete retraction?

[@pitdoctor]

After seeing that, and then hearing it's faster when the system is being run off the engines, I even more want to see footage from a camera mounted under the plane. I'm sure there is a myriad of reasons you can't externally mount cameras on the planes, but I still cross my fingers that it can happen one day.

[@danward8720]

Shaun, when there is that slight difference between the left and right gear extension and retraction does that cause any minor (short) asymmetrical drag you have to adjust for in flight?

[@cq7415]

What if the hydraulic system fails for some reason, is there a manual way to get them down?

[@Mattinspfldil]

Do the flaps have to be in any certain position for the wheels to go up or down?

[@datruth9872]

Hey Rufus , how does that happen ? Moderan Technology Bill ! Woooow. Later !

[@Lee-in-oz]

With the right gear being the last one to come up, do you notice any drag or at least a slight imbalance in the trim when the gear is in transition? Or is one of those things that your muscle memory just counters and you just trim it out without even realising that you are doing it?

[@waldoinaz]

Question Shaun...in the event that your mains aren’t dropping in unison, does it impact the flight characteristics of the aircraft? I’d imagine the drag created by one side being deployed quicker than the other might cause a little yaw.

[@jjsmallpiece9234]

Despite the comments at the end, the starboard door sequence valve probably needs adjusting. Gear movement should be close together port & starboard. Wouldn't have accepted that when I was a jet engineer,

[@mvintrigue-trawlerdiy1101]

Its fine. Actually that plane does quite well with the "pump on a stick". There is actually a maintenance note in the manuals that using this set up the gear may lag so much that the gear may even fall and touch the door under these curcumstances. Even with a full pressure external mule the Hawker gear are rarely in perfect sync.

[@jjsmallpiece9234]

@@mvintrigue-trawlerdiy1101 Fair enough, if you have type knowledge.

[@chrispistel5221]

Can you feel yaw effects from one main gear coming up before the other when you're flying?

[@robertdmoore2592]

They both more than likely retract at the same time with both engine hydraulic pumps running as he explained.

[@daveneely8692]

Ah the sound of a hydro mule, once you hear it, you never forget it. Ever.

[@edschermerhorn5415]

Is the stuttering of the mains in particular a function of the ground generating hydraulic power? If this occurs “normally” does it impact handling with differential drag?

[@mvintrigue-trawlerdiy1101]

Definitely delayed due to the ground power unit. It only drive one pump. In flight both operate.

[@NQUINNT]

Would have been cool if you could have put a camera in the wheel wells

[@ferdinandfrancis9673]

Hi there, is there a particular area you place the jack?

[@geoffeg]

There are specifically designed spots for the jacks.

[@gordonlilley1283]

Shaun; the nose tires have a cuff or extra ring on the out side of each tire. What is that for?

[@keemez]

water/slush deflection

[@mvintrigue-trawlerdiy1101]

Yep..thats the "chine" and it deflects ice and debris outwards.

[@Lee-NN7X]

Do the engine driven pumps supply the same pressure just more volume ?

[@keemez]

people fail to understand fluidic systems in general. increased volume thru a constant restriction = increased pressure. it isn't "pressure" you're going after- it's flow (volume).

[@shannonmcneish4633]

How’s the vette?

[@budc865]

Is there a safety that prevents the gear from being deployed while on the ground?

[@mvintrigue-trawlerdiy1101]

Yes. There is a overide latch that moves into places when there is weight on the wheels. There are also gear pins that actually go into the gear to lock them in the down position.

[@taytayflyfly7291]

You should mention how the chines on the front wheels are there to specifically block things like water from splashing up towards the engines!

[@lionhart2728]

I got a little nervous when the back wheel came out slow

[@gabrielkanter-goodell4968]

Is there a particular reason that the right is slower? Also, why don’t the mains have the same quick drop as the nose?

[@geoffeg]

If it's anything like the plane I fly (Piper Arrow), there is one hydraulic pump for the entire gear system (although I assume the Hawker has a backup pump). As each individual gear comes up, it changes the balance of pressure in the system, which kinda causes that gear to pause while the other ones balance out the pressure. (I hope that made sense). I assume the nose drops at a different rate due to a different design than the mains.

[@vetterfellow]

@@geoffeg I bought it !!!!. If they all dropped at the same time with the same force as the nose gear, that would shake the plane something fierce. Also the length from the pump to the farthest gear would be last to complete it's function.

[@gabrielkanter-goodell4968]

Got it. Thanks!!

[@mvintrigue-trawlerdiy1101]

They are doing the ops checks with an electric motor driving one engine pump. In flight both hydraulic pumps operate and put out much more flow and pressure. In those circumstances the gear, including the nose, is much faster and much more in sync.

[@joec2083]

Why does the nose gear come down so fast.

[@tedferkin]

I'm surprised the gear can be operated with the door open. I would have thought there was a lockout to prevent one or the other operating whilst the other was in an unsafe position.

[@pfflyer4973]

Awesome Dunlop throwing right there. Thanks! Maybe one day you can tell us about antennas and wi-fi ?

[@seagullsbtn]

Why does the nose gear have a ridge or lip on the outer edge but mains don't?

[@casparberends2719]

To protect the hub against towbar?

[@geoffeg]

I believe the lip is there to deflect water and other debris away from fuselage-mounted engines.

[@seatravel8536]

Great video. Your emergency gear extension on that aircraft. Is it hydraulic hand pump or some kind of blow down setup

[@johnb7490]

In the Navy , we called that " drop checking ".

[@RS-pq5mo]

No room for stowaways in those wheel wells ..

[@waukeshapilot6462]

I saw the threads on the jack stands, but how do they jack the plane up?????......The Lord himself, could not turn those collars!

[@keemez]

pneumatics

[@mvintrigue-trawlerdiy1101]

Hydraulic hand pump with a long handle. The threads are for the safety locks once the jacks are in the appropriate height.

[@keemez]

on smaller aircraft a hand operated hydraulic jack might work, but bigger beasts (large cabin Gulfstream, for example) would use pneumatic/hydraulic jacks.

[@mvintrigue-trawlerdiy1101]

@@keemez definitely

[@radioace318la]

Lot's of moving parts.

[@davidharris2519]

why does the co-pilots main gear lag behind also just curious how do you get the wheels to stop spinning once they are up in the wells
