Cirrus SR22 Avidyne - Hot Start Procedure

[@russlaw5517]

GREAT TUTORIAL!!!! Thanks for publishing this. I am a CFI-I and will have all my students watch (and hit the like button). Thanks again for the well explained process(s).

[@cinedelasestrellas]

Thanks for the tip, I have I try this. There’s an airport I stop off for fuel sometimes and it’s a huge pain to get the engine restarted after the few minutes it takes to get fuel. I always and up guessing - going back and forth with the flooded start procedure, lean, half lean, different throttle settings, until it finally goes. I always feel like the I’m looking like a fool to any observers on the ramp, but the hot engine can be really uncooperative. The POH actually does have a “hot start” procedure but it’s pretty useless. It just says not to prime if it was sitting less than an hour, and to use a little prime if you start after an hour.

Mark, just my two cents: if I stop for less than 15minutes I have great luck in my SR20 starting the plane without any priming or boosting…just simply: Full mixture, throttle 1/4 open, and crank!!!

[@cinedelasestrellas]

@@hokiepilot4286 Thanks. I actually just flew with a friend who had an SR20 and he did something similar to that: Mixture rich, throttle open a tiny bit, start cranking while simultaneously turning on the boost pump, then slowly advance the throttle (with the starter engaged) until it starts. Seemed to work fine. I have an SR22 so it’s a different engine. I have since tried the technique in this video and it actually did work pretty well for me. The only thing I’d add to what the video says is something I heard from another video: once you hear the engine kick, do not disengage the starter right away. Keep cranking with the starter until all of the cylinders begin firing.

I love how there's about 50 different ways to hot start a SR22

[@arnaldoleon1]

And none of them work!

[@djdalite]

@@arnaldoleon1 tried and true for all, flood the piss out of it, cut off fuel and open throttle

[@w5cdt]

I have another hot start method that works well on the SR20: Throttle mid, mixture mid, LOW boost. When engine fires, retard throttle and mixture rich. Then taxi lean after engine is idling smoothly.

[@Igorms01]

I use this method: Mixture cutoff, power 1/2 on " W " pump on boost as FF reaches 0.1 i cranck. Once the engine fires i move mixture up.

[@LockheedStarliner]

You forgot to put the mixture back to IDLE CUTOFF after priming at 3:07

[@bobl78]

after more than 100 years of flying, I´m curious when we´ll have small aircrafts with electronic controlled engines that are to be used just like a modern car engine.. start, run, stop .. my good, fuel vapor in the fuel pump, mixture control.. I guess pilots need that to be happy...imagine you have to manually control mixture and ignition timing in your car

[@Sokeresa]

Well said

[@andysim232]

Everything happens slowly in Aviation. There are many reasons as the why planes dont generally have injected engines, mostly the added complexity and cost of maintenance and having fewer electrical components. Then there are the crazy diesel engines that run on Jet fuel just to confuse things

[@LeantoPeak]

That would destroy half the fun, if you ask me :)

[@cinedelasestrellas]

I recently saw a documentary on electric planes. Talk about simple; there’s an on/off switch! Turn it on and the prop spins. Turn it off and it stops. That’s it. When you are taxiing and you want to stop (maybe to hold short for instance) there’s no idling; you just turn the engine off!

[@drewzerTV]

Cirrus G7 SR models have push-to-start

[@aviacaoesimulacao]

Great video. Thank you for this!

[@azautoguy]

Should I see even a small amount of fuel flow? Throttle and mixture at idle cutoff I still see about 4 gals per hour of flow.

[@manuelrios3542]

Also it doesnt talk about the type of induction system normal aspirated/turbonomalized/turbocharged and the influence over the start procedure.

[@lukebelvin4900]

I'll tell you all a method that works for me 100% of the time, simple and sweet. MIX Rich Throttle Cracked BATT on Turn ignition followed by BOOST PUMP ON immediately Will crank up right to 1000 rpm ever single time.

[@lukebelvin4900]

Do not prime at all for hot start using this method.

[@crutchercustomhomes1651]

Are you turning Boost on while cranking or once it fires?

[@lukebelvin4900]

[@CyrilDeretz]

Thanks for the video. Very useful. How do you know if you have a leaker? What symptoms do you need to look for?

[@zacharynorman397]

Your airplane will literally "leak" fuel. This use to happen to me in the 172's early on in my flying career. I didn't even know what was wrong until another pilot came over to me and told me to get out of the plane and look. There was a huge puddle of fuel on the ground. At that point, you have two options. Either wait for the engine to drain (30+ minutes) or do a flooded start. Engines usually get flooded from over priming.

[@SR-bh5jd]

Blue dye stains near the nose strut.

[@Sokeresa]

You know you have a laker when you put your hands down her pants it feels wet. Or when excited squirts at you. In order to fix, satisfy leather more often. Oh shoot, did i say that out loud, oops.....

[@manuelrios3542]

It doesnt say anything about the boost/prime position with the flooded start procedure.

[@MoraesFS]

to start a flooded engine it's recomended you to keep the mixture cutted off and full throttle, then start the engine, as soon as it starts you change mixture position to full rich and throtle back to 1000rpm. If you do it fast enough and properly it'll be a smoth start up.

[@Sokeresa]

Boost and prime off, engine is flooded, making it has fuel already! Jesus, you a pilot or what. On a flooded engine you boost or prime means you will overflow the already flooded engine. Flooding means full of liquid, in our case fuel. Watch the first party of the movie it explains it very well what each thing does

[@Tharkunify]

Excellent. Thanks.

[@markadams7328]

Awesome information - THANKS! One thing I noticed with the hot start was, after you started the engine, your camera showed the console area with the mixture 'off'. Was that a simple 'editing problem'? :-)

stop screaming at me.
