Performance - Climb et al: FINAL 4040 Flashcards
Maximum range airspeed does not change throughout the flight.
true
false
false
For maximum rate of climb we want ________ in the ___________.
largest horizontal distance traveled / shortest amount of time
smallest vertical distance gained / largest distance traveled
greatest vertical distance gained / shortest amount of time
greatest vertical distance gain / shortest distance traveled
greatest vertical distance gained / shortest amount of time
As a rule of thumb, when flying into a headwind, a jet pilot should do what to his max range airspeed?
Do nothing. Wind does not affect range.
Increase it by half the value of the headwind.
Increase it by the full value of the headwind.
Decrease it by half the value of the headwind.
Increase it by half the value of the headwind.
For both a jet and piston powered aircraft, range will increase significantly with an increase in altitude.
true
false
false
Many jets use long range cruise (99% max range) instead of max range mach number. This is because you get a large increase in speed for only a 1% loss of range.
true
false
true
For a prop airplane, maximum rate of climb occurs at ___________.
L/DMAX velocity
A velocity greater than L/DMAX
A velocity greater than L/DMAX
L/DMAX velocity
The two factors that play the biggest pool I an Aircraft’s landing ground run are _________________.
touchdown speed
weight
runway slope
number of wheels with brakes
touchdown speed
weight
Aerodynamic breaching is most effective during the ____________.
the last part of the landing ground run.
first part of the landing ground run
first part of the landing ground run
What is true about the glide of a C-5 weighing 700,000 lbs and one weighing 400,000 lbs?
They will both glide the same distance, but the 700,000 pound airplane will glide faster.
Surprisingly, since the heavier aircraft has more potential energy, it will glide further.
They will both glide the same distance but the lighter aircraft will glide faster.
The lighter aircraft will glide further
They will both glide the same distance, but the 700,000 pound airplane will glide faster.
Maximum endurance is determined by _____________ for jets and ____________ for propeller airplanes.
work required / thrust required
thrust required / power required
power required / thrust required
thrust required / work required
