Hey guys! I wanted to ask you guys a question. What is your initial VS as soon as you rotate to about 500-1000 ft? I usually go straight to 2500fpm as soon as I rotate, but it docent seem right because I look back at the runway and I seem like I am just way too high for not even being past the runway’s end.
I slowly move up to 15 degrees, and at my climb speed of 170-185kts, I usually get 2200-3100FPM on my takeoff climb. 2200FPM at 200+kts though will reproduce what you’re eluding to.
There really isn’t a set VS. It varies by your weight, aircraft, elevation, n1, etc. I do whatever keeps me at my v2 speed until its time to start cleaning up the aircraft and I am past 1,500 AGL.
It depends on your aircraft type and weight. I’ll do VS 1600-2600 range.
Thanks for the answer you guys!
There’s no set VS, it depends on aircraft type, for example the 752 climb rate is much higher then other aircraft. Also the weight can be a factor. For me you judge it on what feels comfortable, there’s no set answer the balance is between what is comfortable to do and also the most effective and efficient.
I go up to 15* and stay there. Depends how heavy the plane is
This explains how takeoff V/S is related to thrust and speed. The thrust primarily determines your V/S
Thank you, @Rob_M !!
