what is the difference between full power and spool up?

Isn't spooling up the process to which an engine develops full thrust?

Bernoulli, what was the spool time from IDLE to FUll in the 727. Isn't it like 12 Sec?

Spool up on the JT8D was anywhere from 6 to 9 seconds. Doesn't sound like much, but when you really need it, it can be an eternity.

Think that was bad? The B36 had such a slow spool up that the plane was landed at full RPM with a drag chute to slow it down. If a go around was required, the chute was jettisoned. icon_surprised.gif icon_surprised.gif

This aint off topic or nothing, not sure if some of you guys know this but on most takeoffs the throttle is pushed until 40% (usually) then either the pilot or the computer goes to whatever thrust the plane is going to use on takeoff. Just letting you know incase you every wondered why when you roll onto the runway the initial thrust seems quite weak then all of a sudden you are crushed like a ant in your seat. they do this to let the engines accelerate evenly as above a certain percent its pretty uniform.

Don't you have to wait until certain RPM is reached before you can apply full throttle (FADEC handles that now) to avoid surges and flame out?

On engine start you do. Once it's lighted, it's all yours. At least on the old JT8D flamers.

Don't you stamp on the pedals build up 40% N1 and then like Mcchord_AFB_Airman said build it up to watever speed is required.



Oh this is off topic and a question for the teacher

When is the autopilot usually ingaged? Is it after a possitive rate of climb established?
