Frage 1
Frage
Q1. In a piston engine, if MAP (manifold pressure) and RPM are kept constant with the ascend:
Antworten
-
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
Frage 2
Frage
Q2. Select the correct answer about piston engines performances:
Antworten
-
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.
Frage 3

Q3. About the piston engines operation, which of these is not a power control parameter:
Antworten
-
Rotational speed (RPM)
-
Mixture
-
Thrust
-
MAP (manifold pressure)

Antworten
-
Maximum climb rating
-
Maximum dry rating
-
Combat or contingency rating
-
Intermediate or military rating
Frage 5
Frage
Q5. Which of the following is a management function of FADEC:
Antworten
-
Automatic start-up
-
Calculation and application of thrust limits
-
Manual thrust management according to lever position
-
All of them
Frage 6
Frage
Q6. About turbopropeller control, which of the engine operation configurations does not have a separated condition lever to select RPM:
Antworten
-
Single-lever engine operation
-
Two-levers (for fixed turbine)
-
Three-levers (for free turbine)
-
Alpha or Power engine operation
Frage 7
Frage
Q7. What is not a ground function of the APU (Auxiliary Power Unit)?
Antworten
-
Source of electrical power
-
Source of pressurized air
-
Hydraulic power
-
Fuel injection and ignition
Frage 8
Frage
Q8. Select the correct answer about jet engines performances (considering that all of the parameters not named remain constant):
Antworten
-
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.
