- FlyWire looks at starting the Big Bore Continental engine in the A36 Bonanza. Hot or Cold there are lots of techniques. Check out what works for us!
FlyWire is about exploring flight and the freedom this incredible experience brings us on a personal level. Flying has always captured the imagination and excitement of living life to its fullest. Hi, I'm Scott Perdue. In a former life I flew the F-4 and F-15E, more recently I retired from a major airline. I've written for several aviation magazines over the years, was a consultant for RAND, the USAF, Navy, NASA as well as few others, wrote a military thriller- 'Pale Moon Rising' (still on Kindle). But mostly I like flying, or teaching flying. Some of the most fun I had was with Tom Gresham on a TV show called 'Wings to Adventure". We flew lots of different airplanes all over the country. Now with FlyWire I want to showcase the fun in flying, share the joy and freedom of flight and explore the world with you. Make sure you subscribe if you want to go along for the ride!

Thanks Scott!
I enjoy all your videos and look forward to future ones, Scott!!! Thank you
Thanks for the video, regards from Brazil, I vê tried in a bonanza f33-a and it worked really well
Thanks Scott. I will try it. I had tried that technique before but I was advancing the throttle much slower . Hot starting our Deb is a real pain....to the extent I just plan trips nonstop to avoid it.
Great Video Scott. Thanks for taking the time.
Another nice video Scott. 👍🏻 A great point was made when you said there’s a bunch of techniques out there and pilots should use what works for them. I fly my A-36 about 340 hours per year and get plenty of opportunities to do hot starts. Here’s my take: A “True” hot start won’t be experienced if the engine has not been brought up to normal operating temperature then allowed to sit and bake for an hour in the hot summer (while you eat that $100 burger). IMO A quick start up and run to the fuel pumps won’t get the engine that hot either, so a normal cold start works fine.
The real test is when you know vapor lock has occurred while the engine sat for a while after shut down. You can actually hear the fuel pump cavitating when you run it during priming. For me, those starts work best using the “cycle the fuel” for a minute with the controls at idle/cutoff. I will usually have to walk the throttle forward during the actual start sequence until the correct fuel/air mixture is achieved. Keep up the great work.
Thanks! Walking the throttle forward is exactly my technique. I appreciate your comments.
Trying this as soon as get my bird back from its annual, thanks for posting
Thank you for your tips. I tried the cold start method on my lake and it works amazingly well, starts right up. Hot start is a different story, it does not like your method, so I just leave the mixture cutoff, still fuel pressure, throttle at ~1000 rpm setting and I hit the starter and once it catches I slowly bring the mixture to full.
This is great to have a person who wants to help out with reading off the Checklist is great and a great way of a person who wants to become a successful professional pilot
Hi Scott, I had a Bellanca Super Viking for 11 years with a IO-520 (300 hp). I used exactly the same start technique (cold) you've demonstrated and can't remember missing a start.
Recently purchased my first Bonanza and my first aircraft with an engine this size. Finding your channel really useful Scott and a big fan. Love my Bonanza but not really a fan of the hot start! Unfortunately the technique you described Scott doesn’t work for me and I find that the only technique that works reliably for my motor is the deliberate flooding of the engine then mixture to idle cutoff throttle wide open then bringing in the mixture when she fires. As you say your hands kind of get in your way doing it , I feel I have too few hands and need another one or two to make this technique works the first time! Sometimes I have to try this technique 3 times or 4 before I can really catch it. I am actually starting to get a little worried about burning my started or causing an inadvertent fire ! My motor has a tornado alley turbo normaliser installed and my mechanic thinks there is some sort of a fuel overflow valve which isnt there and installing that may help . In giving that a go next for another $500 in the hope that might make hot starts easier but I am not feeling overly optimistic about it!
Good luck!
Scott Perdue You're a genius. I went out today to pre-flight for tomorrows flight and had to try it. I have to say, this has to be the best hot start method I ever heard. Now I have only been flying for a little over a year. My Bo is very picky about a hot start! The only way was to run the fuel pump for a quick count of 30 before starting according to POH....the ONLY WAY. I hate running the fuel pump that long. I ran over to the fuel pump put the key back and tried what you explained in the video and she cranked for about 5 seconds until the throttle was in the sweet spot and she started right up as you said. I drove back to the hanger and just had to do it again.
Jimmy, I'm glad it worked for you. I appreciate your comments!
@@FlyWirescottperdue Sorry to blast more comments on your page. I wanted to share my experience with my flight yesterday. Typically I have to run the hot start procedure any time of day after I have run the engine, even if it was for 5 minutes. The only time I would use the normal starting checklist is the very first start of the day. I flew to Houston (KIWS) from Abbeville (KIYA) a little over an hour flight time. I make the trip every couple of weeks. I'll run around Houston for 5 or 6 hours depending on work. When I'm ready to head home I'll run the Hot Start and bang I'm ready to go. Well, yesterday was another opportunity to run the new procedure. I had a friend with me, a very experienced Commercial Pilot. I told him we were going to try a new starting procedure today. I gave him a short explanation and off we went. I followed your protocol as I pushed the throttle forward about 1/3 of the way in engine kicked off and I worked the throttle a little back and forth to get the engine back to idle and ready to run my next step on my checklist. Again sorry for the rant, guess I'm just so amazed at how well this works after I tried everything else. Save the battery and fuel pump.
We hated a hot start in our old Comanche 400 ...the flat 8, particularly in hot weather.
We used to have to flood it to rid the vapour and then with mixture in cutoff and with full throttle we had to absolutely flog the starter.
A right pia.
I’d love to hear from anyone who managed it with less pain .
For the hot start I do the same thing but I leave the throttle full in and slowly pull out. Usually goes in 1-2 turns. Throttle goes to idle before the prop has time to speed up.
Thanks for the video. Enjoy seeing well thought out procedures. An alternate method I've seen work is almost identical to yours, but you start with more open throttle, and bring the throttle back smoothly. I think it would fire at about the same throttle position, except your hand is already smoothly moving back to an idle power setting. Wanted to see if you've tried it that way.
Ryan- Indeed, that is my big bore Lycoming start procedure;)
Preflight Before starting Checklist in every aircraft I fly because my instructor always said that because you fly every day you will never know how easy it is to get distracted by a passenger or someone asking you why are you doing that and you have to start over and go through it with your passenger who's seating in the right seat
👍👍👍👍👍👍👍👍
My preferred technique is to leave the throttle at idle and mixture where it is for normal ground ops. Then go to start and start the fuel pump. Fires right up every time. The problem is the heat soaked mechanical fuel pump vaporizes the initial fuel until it gets cooled off enough by the fuel.
If it works, it sounds good to me!
Scott,
I use exact same technique for my IO-520 cold as well as hot. Works all the time!
Great videos by the way 👍
Which iPad Mount do you use?
Timo
Timo- I use a RAM mount. I'm actually converting to a MyGoFlight cooling system to mitigate the impact of heating from the Sun on my iPad. Perhaps, I'll do a review when tis all set up.
FlyWire- scott perdue
Great! Looking forward to that review.
Stoichiometry - I'll have to review that 🙂 What's an unfrozen fighter pilot again? I get there needs to be some measure of accuracy...
Merry Christmas and Happy New Year ~ hope '21 is better for all of us.
PS - friendly reminder - please keep being careful of Covid - definitely not pretty if you have to deal with it directly. Good luck - stay healthy!🙂🍀🌠☕🧭✨🎄
Merry Christmas and Happy New Year!
Beechcraft Bonanza/Baron are a genuine gentleman’s carriage compared to the Comanche which is almost like sitting on the floor in comparison ......a genuinely swell way to fly.
Since owning my A36 I have run the fuel pump for about 30 seconds for a hot start and it works fine but I will be trying this. Cheers.
Why not more diesel small aircraft engines ?
Not enough power and to much weight.
Where are you based? Looks like a nice airpark.
Southwest of Fort Worth, Texas. Not to bad;)
Let's be fair, a 5 minute engine run on a sweat shirt day does not constitute a problematic "hot start" condition.
Serious Mark? Maybe I was just showing my technique.
@@FlyWirescottperdue Not looking to quibble...but to my 15 yr BE33 experience fuel line and fuel pump vaporization at 90F after a refuel at the pumps requires the closed loop pumping you mentioned. It is specified in my Beechcraft POH, not merely a recommendation.
Does anyone know where to buy this type of aircraft?
Try the website trade-a-plane
Thanks!
....."He mumbled"
Checklist? Beacon was off when you started. you taxi fast like a southwest airliner. Audio was really bad....
Sound quality extremely poor.
Great Video Scott. Thanks for taking the time.
