an aeroplane at 20 000 ft will slip through the air faster than one at 5000 ft as the air is less dence, to get the same parasitic drag therefore the same lift. so you go faster with a little more power. this over compensates the engine loosing power at altitude.
true or false?
what i want to know is will a helicopter travel faster and be more economical at a higher altitude or will the lift required out weigh the extra speed?????
