We set "Standard Power" or "Max Power" with the throttles/thrust levers. I wonder how we ever get airborne.Occam's Razor said:No jet takeoffs are a max "power". Power is for props. Jets use thrust.
And yes, most takeoffs are done at "reduced", "flex", or "alternate" thrust settings. If the runway can be balanced and the aircraft meet second-segment climb requirements, using reduced thrust reduces wear on the engines.
Godvek said:Pre-V1 is not the only factor in an abort decision. There are high-speed and low-speed aborts. Usually 121 carriers consider anything above 80 or 100 KTS a high speed abort and do not recommend aborting after this speed unless the captain feels flight is not possible. In my company the captain makes the decision to abort. After 80 or 100 KTS (lower than V1) it is considered safer to continue on and have the full length of the runway to stop, even though performance figures allow it. Keep in mind your aircraft is still producing thrust and accelerating even with an engine failure and a high speed abort is more likely to cause tire blow-outs, brake overheating, etc.

Hey, I thought you were in an indulging mood!Occam's Razor said:Geez...I don't know. What static POWER rating do your engines have?
When you land your big jet...do you use the POWER reversers to help you stop?
