I have some trouble getting off the ground in hot or high conditions or if my plane is heavy or if the runway is short or all of those combined with normal takeoff thrust, in these scenarios though is it okay to use high or full power on takeoff
Of course! Airliners do this all the time.
Yes of course.
Hold the brakes, full throttle then release brakes.
Yeah a static takeoff.
you can also do a “Turn ‘n’ Burn” full power takeoff
What turn and burn?
Hey Juan! To answer your last question, a “turn n’ burn” is basically pulling hard and throwing on the afterburners. To turn, as in to change direction; and to burn, as in to go to “burners”, that is afterburners.
However, that’s not a turn n’ burn takeoff like @AlaskaAirfireball111 mentioned above. If I were to guess, I’d say that that type of full power takeoff would look like an aircraft entering the runway, turning, and going full throttle without stopping or anything. Hope this helped!
(@AlaskaAirfireball111 please correct me if I’m wrong.)
no, you are correct
IRL they never use full throttle for takeoff except in exceptional situations such as Samedan in Switzerland where aircraft must hold the brakes and use full throttle for takeoff due to the short runway and high altitude (5600ft MSL) of the airport. If you’re taking off on a runway which is more than 10000ft, you shouldn’t have any concerns and you can takeoff using normal takeoff thrust (80-85% thrust). Don’t forget to use trim and flaps to help you get off the ground faster.
Thanks for the insight Philippe! I do believe that full throttle takeoffs occur at a lot of other places (not just location related) than Samedan. This can be due to runway length as well as other factors such as winds, aircraft weight, and temperature. Below, I’ll link a video of a commercial flight executing a full power takeoff in Orange County. I’m sure @Thunderbolt would know a thing or two about the procedures there too.
Thx, in normal conditions I usually takeoff with 80-85% N1.
No, they use full power quite more often than you might think. Go arounds, hot and heavy, or just a short runway.
It just doesn’t happen often since it’s not good for the engines.
I usually use 90-100% N1 in hot and high conditions or if I am heavy, finally if I feel that I am not going to make it I might increase throttle to 100% PWR.
Yes, also a TOGA (full thrust) takeoff must be used under some conditions such as a windshear warning in the METAR or on a snow/water covered runway as far as I am aware at least on some airlines (not 100% sure about the last part).
I did some research on the internet and I read that pilots calculate how much throttle they will need to takeoff based on weight, weather, runway length, and other factors. So it’s possible that the pilot used 95% thrust but that isn’t full thrust…
Yes, and in certain scenarios 100% is necessary…
That’s correct, yes.
That’s possible too, but TOGA (full thrust) takeoffs do happen from time to time as well. And TOGA on a go-around as @Altaria55 wrote is rather standard.
I rarely use it though unless I really can’t get in the air and I am past V1.
But what I’m trying to say is that he shouldn’t use full throttle for every single takeoff. If you’re gonna takeoff at KORD for example, there is no need for a TOGA as the runways are more than long enough.
