So, I realise that take off varies alot depending on weight, altitude, aircraft, engine power, bladi bla bla…. But there are times where my plane (say the CRJ) shoots like an arrow in the sky with N1 around 90%, whereas there’s times where a 737 or heavier takes a lot more than that… Also, and this is the important one, having watched videos on youtube, it always takes a little while for the aircraft to reach flap retraction speed (around 180-200 kts, I think).
So, I was wondering if there’s any real pilot reading this who can advise. What is the normal N1 setting for take-off, and what should the climb rate be (on average)? How can I avoid N1 going from vr (say around 140) to 200 kts in less than 10 seconds (or indeed, is that normal).
Is there a speed management app that tells me what are the V1/VR speeds for my weight, and my flap retraction speed?
Anyway, would appreciate the clarifications.
