Hey Old Fella, I think maybe I didn't make my ponit very well. I'l try again.
I was responding to
get an odd feeling about lack of acceleration/airspeed and runway remaining, and I dunno, manually increase thrust?
The point I was making is that the variation in thrust (and therefore accelleration) is so great from one departure to the next that you may not get that ´odd feeling´.
For example, I could take off on Sydney´s 34L with an assumed temperature of 66 degrees and slowly lumber down the strip and struggle into the sky and there would be plenty of margin. Then two hours later I could depart from 34R with an assumed temperature of 38 degrees, the accelleration would be much greater than the departure off 34L (thats where I got the ´lively´from) yet it would be insufficient thrust for the runway and conditions because an assumed temperature of 32 degrees was required.
Does that make more sense?
