400 to 500 feet and rather than getting a climb your VSI and altitude are going down?
Pace,
Last post for me as you've proven you're not good at listening.
If, in the above situation you now lower the nose to accelerate (assuming you were at the correct Vyse at the time), your descent will increase and will stay that way. Thus your hole in the grond will be nearer and deeper.
As to "Step climbing" a Citation, if you didn't have the excess thrust to get to 370 in the first place, you won't have the thrust to stay there.
Find me one authioratative text that refers to an aircrafts level airspeed as a "Terminal velocity."
As to being an "armchair pilot", MY armchair is located at the front left of a Boeing 777!
