Q1. In a piston engine, if MAP (manifold pressure) and RPM are kept constant with the ascend:
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
Q2. Select the correct answer about piston engines performances:
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.
Q3. About the piston engines operation, which of these is not a power control parameter:
Rotational speed (RPM)
Mixture
Thrust
MAP (manifold pressure)
Q4. Which of the following is not a rating exclusive for jet military aircrafts:
Maximum climb rating
Maximum dry rating
Combat or contingency rating
Intermediate or military rating
Q5. Which of the following is a management function of FADEC:
Automatic start-up
Calculation and application of thrust limits
Manual thrust management according to lever position
All of them
Q6. About turbopropeller control, which of the engine operation configurations does not have a separated condition lever to select RPM:
Single-lever engine operation
Two-levers (for fixed turbine)
Three-levers (for free turbine)
Alpha or Power engine operation
Q7. What is not a ground function of the APU (Auxiliary Power Unit)?
Source of electrical power
Source of pressurized air
Hydraulic power
Fuel injection and ignition
Q8. Select the correct answer about jet engines performances (considering that all of the parameters not named remain constant):
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.
