TBM 930 Start Up Sequence (From COLD and DARK Cockpit)
ฝัง
- เผยแพร่เมื่อ 15 เม.ย. 2020
- Recently I was able to take a ride upfront in a TBM 930 and film the experience. Starting up a turboprop is VERY fun as you can feel the raw power it generates, slowly spooling up into a monster of an engine. I've always loved cold and dark startup videos and so it was fun and rewarding to get to document the startup sequence of this awesome aircraft!

Hey guys! I wanted to let you know I just launched an "Insiders" Newsletter where once a week I'm sharing an important lesson I've learned in aviation, links to my latest content so you don't miss out, and links to any other interesting or helpful content I've found. I'm also working on a HUGE project I can't announce yet but I'm going to be sharing more behind the scenes info with Insiders first - Subscribe (it's free) at: airplaneacademy.com/insiders
useful for MFS2020, thx
Same here. The in-game checklist is totally wrong
This makes you realize how much stuff is missing in the flight sim.
Von W. Whatever is not missing is wrong or doesn’t work properly. So everything!
Von W. It’s default. What did you expect?
wtyisgreat it’s default, what did you expect?
Who's here after downloading Microsoft Flight Simulator?
Me! I can already tell this is going to be one of my favorite planes to fly
Awesome!
Me. This plane is so challenging compared to flying the normal single props and bush planes.
Yeah! It’s just too unstable for me, compared to the other props
@@inrptn I'm able to get it running but I dont know what to do for the ITT it always goes above 850
Flying the 930 in MSFS right now, and when that alarm went off I checked the sim. 😄
congrats to your Dad for doing so well- he must be very proud and happy that his hard work has enabled his family to see and do things like this- nice work!
I like how you don't need to yell, "Clear prop!"
Great video. You certainly known the systems well. I’d love to take a spin in a TBM at some point. What a machine.
Thank you! Left seat is my dad so I can't take credit but I'll pass this along.
Outstanding video - Thanks for showing in complete detail, and extremely well described the full Cold & Dark Startup Procedure. So many videos leave out little, key details. For someone who really hopes to learn the correct procedure, this type of video is very much appreciated - Thanks!
Thank you!! I'm glad you found it helpful!
Compliments to your dad. Great video. Loved every bit of it.
Thank you a lot for sharing !
Love it!!! Sorry about these deadbeats that hit the thumbs down button , these bots have nothing better to do and have no appreciation for the hard work that goes into bringing us these videos.
Thanks so much! Really appreciate this. :
Outstanding walk through on startup. Thank you.
Thank you, glad you enjoyed!
Wow!! Well done!! Thanks!!
thanks and glad you enjoyed it! -charlie
This thing is fantastic, it really is. A turboprop that can cruise at 30,000ft at 330kts.
Until crap head winds try to kill its shine 😮💨
Love these videos- currently geeking out on turboprops for some reason.
a turboprop coming out of feather and rolling into ground idle is one of the greatest sounds the human ear is capable of hearing
Thanks for the video.
You bet
Good stuff thank you
Glad you enjoyed!
Hi there. An interesting video...
However, a few points: As near as I can tell, the aircraft has the Pratt & Whitney PT6A-66D engine. There are a few things that are common to the PT6 series engines. 01:22 you state you're starting on Battery AND Main Generator. Your engine is equipped with a Starter/Generator -it functions solely as a Starter until the engine reaches self-sustaining Ng (around 48%) and the starter auto-disengages AND the Start switch is returned to the OFF position. Then (and only then) it functions as a Generator, supplying the aircraft power busses.
At 2:50 you see 21 AMPS on your EIS... that does not indicate the health of your battery for engine-start. At that moment, all it is indicating to you is your battery DISCHARGE rate, with all your avionics on. You won't see your Start amperage UNTIL you're turning your engine.
At 3:40 you state (paraphrasing) "at 13%, introduce fuel". The P&W Manual states 12-13% (depending on engine variant) is the MINIMUM Ng to introduce fuel -not the TARGET Ng. If your battery is healthy, or you're starting on an EXTERNAL Power Source, why not let the engine spin-up to a speed closer it's potential? You'll not exceed any Starter time-limits, and you'll get a cleaner, cooler start! In mine (-140) cold-start, external source the engine will spin-up to 18-19%, if I go for every last turn the battery will give me, easily. However, turning it quite that far is unnecessary and unhelpful. I generally put the fuel in (on a cold-start) when the engine is still accelerating on the battery, through 17%. Warm engine starts are based on Ng AND ITTºC -again around 17% and cooling through 180ºC on my engine.
hmmm... seems my reply was clipped.
You later 03:46 speak of "...half the igniters, burning..." Ahhhhhmmmm sorry, just Nope. Your igniters are an All-or-Nothing proposition. They're either all ON or they're all OFF. There's no half-way deal. Unless you have a fault that requires engineering assistance. At that point of your engine-start, and listening to your engine, I assume you mean you have half of your engine FUEL-NOZZLES active -which is precisely how PT6 engines start. At around 38% Ng, you'll hear your engine accelerate again, see a lower ITTºC peak and an increase in your displayed fuel-flow. That is your Secondary Fuel Nozzles engaging. The engine will then stabilise at around 48-52% Ng, with the starter disengaged and ITT stable. Start complete.
I bet the answer is as simple as a regulator turning a field off and on to charge the batteries. The battery does the rest. Sorry my mind follows tributaries at times. Thank you kindly for the effort of the reply.
@@RadioSaigons I’m not saying that everything this guy said in this video is perfect (I don’t think it is), but as far as procedure goes you are arguing the aircraft manufacturers checklist vs an engine manual. In any aircraft there are checklists for things like starting the engine, you take on a lot of liability in deviating from that just because you think you know more about the engine than the company that chose to put it into their aircraft.
Great video! Just what I was looking for to help me with the TBM930 on MSFS2020. Please do more videos on this excellent aircraft. Thanks!
Awesome, glad you found it helpful.
Fun!
it was!!
Hello Nice video not too fast Well detailled actions Thanks
Thank you!
Cool
I would love to fly that plane
What a Geat Video,,, Good Job,,,, As For You Copilot,,, He Needs More Coffee,,,
That baby is about as smooth as the 82 warrior ll I fly lol, I’m guessing it smooths out as RPM and pitch change? Nice video always interesting to see dark to starts on different planes.
In MSFS2020 I cut fuel to my engine as a, "Oh what's this do?". And here I am. I crashed before I saw how to restart then engine. But now I know Thanks : D!
Same here, on my first 1000 NM trip... after about 300 NM of flight :D Fortunatelly at 26.000f i had enough time to find out and restarted the engine at 12.000f succesfully thanks to this vid :D
Ha, well now you know!
Great vid. Just a question, it runs a bit lumpy for a turbine no ? :) Pilots and Cams shaking, I expected it to be silky smooth.
Awesome video, can't beat that start up sound it's just beautiful. Quick question.... How does the turbine start on these without (im assuming) any bleed air from an APU or GPU etc? Is the battery alone powerful enough to start the turbine?
PT6 engines utilize a starter-generator, which draws power from the aircraft battery to start. Once the engine is on-speed, the starter-generator changes roles and provides power to the aircraft DC buses.
Thats why i drive a 1966 Corvette!!!
I really love this video. But when I start the TBM motors in FS2020 I cannot follow all those procedures to the letter because I have the cup of coffee in my hand.
563 degrees Celsius is hotter than the surface of Venus
I'll never get why in generations of general aviation no one has made a cockpit that has elbow room.
thanks - but is'nt there unsual vibration ? is that normal ? idont see in other tbms
hello ..... can you explain how you select the GEN ON pefor you start any sources for the generator to be selected ??
OR that was (ALTERNATOR) ? because ther is no APU or engine GENERATOR before start any one of them So you don't have APU in your airplane which means NO APU GEN generaror !!SO the only source it can be available to you to transfer DC to AC is the ALTERNATOR (wech is you van technically consider it as( GENERATOR ) So is that what you mean ?
Does TBM have a degree program for startups?😄
I believe all the TBMs have an 850 SHP engine, but the Pilatus PC-12NG & NGX has a 1200SHP engine. Now the TBM all re supposed to the fastest planes of their types, but they only seat 6 people including the pilot. The PC-12s can be configured to seat up to 11 or 12 including the pilot.
They’re not really comparable aircraft - also it’s thermodynamic power is technically 1800hp but is flat-rated to 850.
The pilatus is more of a utility aircraft, the TBM is a small vip type aircraft with jet-like speeds.
@@EstorilEm I knew that they are all flat-rated to 850SHP. You can also get them equipped pretty much the same way so to me they are comparable.
ITT you mean for hot and wet starts, NG is for hung starts as far as I know.
Actually a hung start will result in a hot start if left too long.
ITT for Hot Starts, Ng for Hung Starts, and there'll simply be no Ignition in the event of a Wet Start.
@@RadioSaigons IN the end a hot start may result from a hung start ... A Hung start has ignition, but no acceleration.
@@daviator4720 Correct. Not disputing that -but a Hung start SHOULD be caught and corrected at That stage, well before it develops into a Hot start. Stagnating Ng will still be your indication of a Hung start, along with increasing ITT.
@@RadioSaigons Absolutely!
5 degrees Celsius? That's not cold. That's nice.
I thought ITT would tell you hot starts and NG would tell you about hung starts?
Steveo fan?
Hearing him say that every flight has programmed it into my head.
Eric Gentry guilty as charged!
I'm not a pilot so I know basically nothing about aircraft. My question is there seems to be quite a bit of vibration shortly after initial start up, where is this coming from?
I'm using older gopros here and the stabilization isn't as good as it is in the newer models. Sometimes certain vibration frequencies can rattle the mount and camera more than others. Some RPM's are smoother than others.
You forgot to check the muffler bearing
what is the one on the left wing that look as a missile and why it is not on the right-wing?
Radar Pod.
Radar.. usefull for weather was well
Plus you only need one. Lol
You would think that in an airplane that expensive, there would be a "start" button
They included it in the even more expensive TBM960.
Love this bird....if i was a millionaire i would definitely buy it as my private plane.
Dude you need to be a lot more than a millionaire to afford that gal
@@StepAttitude plane cost roughly $4 million. Millionaire making or got 24M in the bank can afford it and maintain it. Plus many folks including companies dont buy aircraft in full cash. They finance and determine their operating margins
@@dmatthieu2 God bless you. Having that kind of money in the bank gives you lots of options to have nice things. Kudos to you!!
@@StepAttitude i don't have that in the bank Keith...at least not yet 😏. I'm just trying to let you see that it is attainable and affordable as a millionaire. Maybe even for someone with an annual salary of over 600k per year with outstanding credit. The operating cost of this airplane is very low when compared to others. That's why its such a huge hit.
@@dmatthieu2 Well, I'm halfway there. It would be very satisfying to own a plane like that.
Did not turn on the alternating beacons before starting the engine?
What is an EIS system?
PC12 NG is SO MUCH SIMPLER to start!
Why does the plane shake so much with the engine running on th ground?
because during check list the engine ramps up enough to provide thrust. With brakes applied and thrust.. the frame shakes as it has no way to exert that energy. this is normal as this procedure is to check if the engine is performing under load before takeoff.
@@itHurtswhenIP I see. Thanks for the information.
If only Flight Shitmulator included a g3000 with a few more functions than an old calculator and a brightness adjust knob 😞 . Great video by the way, great aircraft!
It’s default. What did you expect?
Thank you!
At 13% ng introduce fuel and half the igniters ? are burning. At 52% another set of igniters ? will come on. In your talk through you have repetitively refered to the injectors as igniters. Is there a reason for this or do you mean fuel injectors ? As in at 13 % Ng introduce fuel so first ring of injectors ignite followed by at 52% second rise in itt due to second ring of fuel injectors igniting which is a bit high I thought, followed by stater disengagement and revert to generating.
Silly to ask but does the aircraft really have a generator or is it an alternator?
A generator creates both AC and DC. But in essence its an altenator with a rectifier circuit.
Not silly at all. The PT6 series engines have a Starter/Generator. It functions as a Starter until about 48% Ng, then as a Generator once the Start cycle is complete. It supplies DC electrical current to the aircraft battery and electrical busses. There is also a Standby (emergency) Alternator (AC, rectified) which can supply electrical needs in the event of a loss of Generator output in-flight.
RaggedyVan Again a question from an uneducated point of view. Generators depend on constant or a constant RPM to output consistent voltage and amperage. What ensures this? Thryristors? Capacitor? battery banks? Just curious.
Sorry @@crawford323 , that's probably a question best directed to an engineer or electrical technician. I'm merely a driver. In the PT6 installation, the Starter/Generator is directly driven by the Accessory Gearbox AGB, which is in turn driven by the Power Turbine. I'd imagine that would be at a fairly consistent speed, within relatively close constraints. Similarly, the Alternator is belt-driven from the AGB. I'm sure there'll be somebody able to weigh-in with more specific detail than I'm able to provide.
Inertial seperator or no need of this ?
from what I understand from the manual the Inertial SEP comes on once the engine is at taxi idle and you should have it on for all ground ops no matter how well maintained the field is. I have never flown a TBM IRL, its just what I read in the POH which is available online free of charge from Daher.

your bearded buddy needs some instruction on his seat belt
you guys are deff not 6feet apart thats a tight cockpit
I guess that vibration is a fouled plug - or the carb is gummed up - or maybe even the distributer cap is loose - eh?
This was filmed before the push to wear masks. I hope these guys didn't get sick.
tofuComputer masks suck
@@friedchicken5227 agreed. I hate wearing one but we gotta do it.
tofuComputer sweet Jesus, not everyone has to wear a mask. Don’t drink the koolaid
@@Punchacow Oh so you don't care if you inadvertently make someone else sick? Are you a doctor? What qualifies you to make this (utterly false) statement?
tofuComputer are you? Too much evidence out there that shows masks are minimally effective if at all and are potentially more harmful than beneficial. If they were sick they wouldn’t be in that airplane. Masks are supposed to reduce particles from a coughing person, of which neither of these men were.
What's the purpose of having all those switches should have one switch that simply turns everything on
The cost 3million for the computer crap. The engine 200,000 the rest 300,000 lol..
What the hell is a WET start?😂
pfft. i'd choose a hawker seafury over this thing any time.
A King Air would be half way to the destination before you get through the start up checklist! Just sayin!
Seems like it is a lot to get this thing off the ground.
Why go to all that trouble when you could just hold CTRL+E? 😄😂🤣
I'm sorry but I must comment. I'm tired of seeing pilots thrash on those warning light buttons as if they are toys. Yes it's fine to silence them but come on. Some day they won't work. When my new TBM 940 arrives, I'm going to use those buttons like babies. I'll push it once, calmly to cancel the warning. Sadly if people are so quick to cancel them, they might habitually do it during a real warning situation and not actually pay attention to the said warning.
NO FACE MASK NO FLY
Definently not a plane for a beginner!
