- Thanks for tuning into everybody. This is a quick clip I realized I had on my camera that I thought would be of value to many of you considering stepping into a turboprop aircraft from a piston. The dreaded HOT START. Now, unlike piston aircraft it's simple to start a hot PT6 - but there are critical steps to ensure that your "easy" start doesn't become a $300k one!
While I provide my own technique of dry motoring while rolling into a start, it's imperative that you consult your specific aircraft's pilot's operating handbook and know your engine's temperature and starter limitation.
Thanks for watching!

The History of Socata TBM (now Daher TBM)
The SOCATA TBM (now Daher TBM) is a family of high-performance single-engine turboprop manufactured by Daher. It was originally collaboratively developed between the American Mooney Airplane Company and French light aircraft manufacturer SOCATA. In fact, "TB" stands for Tarbes, France where Socata was located, and "M" stands for, you guessed it - Mooney!
The design of the TBM family originates from the Mooney 301, a comparatively low-powered and smaller prototype Mooney developed in the early 1980s. Following Mooney's acquisition by French owners, Mooney and SOCATA started a joint venture for the purpose of developing and manufacturing a new, enlarged turboprop design, which was designated as the TBM 700. Upon its entry onto the market in 1990, it was the first high-performance single-engine passenger/cargo aircraft to enter production.
Shortly after launch, the TBM 700 was a market success, which led to the production of multiple variants and improved models, often incorporating more powerful engines and new avionics. The TBM 850 is the production name assigned to the TBM 700N, an improved version of the aircraft powered by a single Pratt & Whitney PT6A-66D. In March 2014, an aerodynamically refined version of the TBM 700N, marketed as the TBM 900, then the 910 with standard G1000 NXi. The 930 arrived by 2016 with the G3000 flight deck, which was replaced by the 940 with autothrottles and autoland in 2019. As a crescendo in 2022, the magnificant TBM 960 has arrived, with the Fadec-controlled PT6E-66XT P&W engine (5,000 TBO). Daher TBM has become a powerhouse in business and personal aviation, around the globe with these impressively performing aircraft.
If anyone has any questions on the TBM, aircraft ownership, or purchasing your first plane (to include a high performance pistons like a Cirrus), I'd love to hear from you, as my full time job is brokering aircraft at Mason Amelia.

Great video Jesse…. I spoke to you about 8 months ago trying to decide between the M600 and the TBM 850… Ended up getting a G1000 TBM 850 and WOW what a plane! - Thank You
the start not becoming a 300k one...indeed
Remember the ITVV Boeing 747 video from cathay?
There Don Grange in the Sim demonstrated a hot start on the RB211 engine
"And if it weren't a sim, we would have ruined several million pounds worth of engine"....
True words
very cool, I want one.
Thanks for checking this out!
Great video. But isn’t there a 30 second limitation on the starter? if you are lower than 30% NG, by 30 seconds- starter is supposed to come off no?
Thanks for check out this video! You're correct that the book references 30% in 30 secs and then 60% by 60 secs. However, some TBM instructors count this from the time that fuel was introduced.
The 60 seconds max is for sake of equipment preservation so you don't cook your starter. You should reach those normal "gates" for normal engine start. Adding fuel as late as I did, and having the engine spool up as quickly and cool, see no problem here, respecting the 60 second max always. If I had a normal start hang and stagnate under 30%, dumping fuel, maybe due to a sluggish starter or bad battery as the culprit, continuing the start could cause a lot of damage... Good observation!
Hey Jesse - what is a good way to send you a message or phone call? I’m have a T210F based at boerne.
Hey Chris,
I’d love to hear from you. My cell is listed on www.aerista.com About Us page.
