Question 1 of 8

1

Q1. In a piston engine, if MAP (manifold pressure) and RPM are kept constant with the ascend:

Select one of the following:

  • The power decreases due to temperature descent

  • The power increases due to temperature descent

  • The power remains constant too

  • It is not possible to maintain both MAP and RPM constant with ascend

Explanation

Question 2 of 8

Q2. Select the correct answer about piston engines performances:

Select one of the following:

  • A. Rated power is the maximum horsepower at which the engine is approved for continuous operation.

  • B. Critical altitude is the maximum altitude at which the engine maintains a given horsepower output. It is decreased by turbochargers and superchargers.

  • C. Critical altitude is the maximum altitude at which the engine maintains a given horsepower output. It is increased by turbochargers and superchargers.

  • D. A and C are true.

Select one of the following:

  • Single-lever engine operation

  • Two-levers (for fixed turbine)

Q7. What is not a ground function of the APU (Auxiliary Power Unit)?

Select one of the following:

  • Source of electrical power

  • Source of pressurized air

  • Hydraulic power

  • Fuel injection and ignition

Explanation

Question 8 of 8

1

Q8. Select the correct answer about jet engines performances (considering that all of the parameters not named remain constant):

Select one of the following:

  • With an increase of altitude, there is a decrease of temperature with a corresponding increase of density, and therefore there is an increase of thrust.

  • With a decrease of temperature, there is an increase of thrust if RPM decrease.

  • The greater inlet momentum drag, the greater thrust.

  • The greater the ram effect, the greater the thrust.
