exhaust gases leaking into the cockpit.

A power backup to back pressure in the exhaust system. 

The density of air entering the carburetor decreases and the amount of fuel remains constant.

The density of air entering the carburetor decreases and the amount of fuel increases.

The volume of air entering the carburetor decreases and the amount of fuel decreases.

The density of air entering the carburetor increases and the amount of fuel remains constant. 

will not operate on one magneto.

could accidently start if the propeller is moved with fuel in the cylinder.

Cannot be started with the switch in the BOTH position.

All of the above. 

a greater angle of attack.

the same angle of attack.

a lower angle of attack.

An upper angle of attack. 

will decrease the takeoff distance

will increase the ground roll.

leans the mixture for more power on takeoff.

None of the above. 

is always electric; the turn-and-slip indicator is always vacuum-driven.

Indicates roll rate, rate of turn, and coordination; the turn-and-slip indicator indicates rate of turn and coordination.

indicates bank angle only; the turn-and-slip indicator indicates rate of turn and coordination.

All of the above. 

is the same for all aircraft in the same locality.

varies over time as the agonic line shifts.

varies for different headings of the same aircraft.

None of the above. 

actual distance a propeller advances in one revolution.

Ratio of geometric pitch to effective pitch.

Ratio of thrust horsepower to brake horsepower.

All of the above. 

To maintain a steady rate of turn, the angle of bank must be increased as the airspeed is decreased.

For a specific angle of bank and airspeed. The rate and radius of turn will not vary.

The faster the true airspeed, the faster the rate and larger the radius of turn regardless of the angle of bank.

None of the above.
