Have you flown a large number of jets from which you can draw this conclusion?

PCL_128 said:Don't need to, it's just a basic fact of the physics involved. A given FF will always yield the same speed no matter the temp or altitude. N1, N2, etc... all change depending on your alt and temp for a given speed. Do you disagree?

Huh? Seems like it's been pretty civilized to me!FlamingFUPA said:jeezuz, didn't take long for a thread with usefull suggestions to turn into a pissing contest
Works great for both AS and Alt. After that a little fine tun'n as needed.LAXSaabdude said:Huh? Seems like it's been pretty civilized to me!
And T-Gates, you are right about the trend vectors. One of my instructors taught us to "pinch" the trend vector between the airspeed pointer and the target speed, i.e.as the tip of the trend vector reaches the target speed, gradually add or reduce power so that the tip of the trend vector stays touching the target speed, and the vector shrinks down to nothing as the airspeed pointer reaches the target speed.
Sounds more complicated than it really is, but that's my best explanation.
