All 13 questions — DA-42 NG: Performance, Mass & Balance
Technical Specific · DGCA CPL. The correct option is marked on each.
Q1. The maximum take-off mass of the standard aircraft is:
- A.1785 kg
- B.1805 kg
- C.1900 kg✓
- D.1999 kg
Why: 1900 kg (4189 lb). Higher figures apply only to aircraft carrying an approved weight-increase modification.
Q2. The maximum landing mass of the standard aircraft is:
- A.1765 kg
- B.1805 kg✓
- C.1900 kg
- D.1999 kg
Why: 1805 kg (3979 lb).
Q3. The maximum zero fuel mass of the standard aircraft is:
- A.1650 kg
- B.1765 kg✓
- C.1805 kg
- D.1900 kg
Why: 1765 kg (3891 lb).
Q4. The datum plane is located:
- A.2.192 m forward of the most forward point of the wing root rib
- B.2.195 m forward of it
- C.2.196 m forward of it✓
- D.At the propeller spinner
Why: 86.46 in. It is a vertical plane when the nose baggage compartment floor is horizontal.
Q5. The centre of gravity is calculated as:
- A.Total mass ÷ total moment
- B.Total moment ÷ total mass✓
- C.Total moment × total mass
- D.Total mass − total moment
Why: Where each item's moment is its mass multiplied by its arm from the datum.
Q6. As the aircraft mass increases towards maximum, the forward CG limit:
- A.Moves further forward
- B.Moves aft, narrowing the forward margin✓
- C.Remains unchanged
- D.Becomes irrelevant
Why: A heavier aircraft has less room at the front of the envelope.
Q7. The maximum load in the nose baggage compartment is:
- A.10 kg
- B.18 kg
- C.30 kg✓
- D.45 kg
Why: 30 kg (66 lb). The cabin baggage compartment takes up to 45 kg (100 lb).
Q8. Exceeding the maximum take-off mass results in:
- A.Degraded flight characteristics
- B.Degraded flight performance
- C.Overstressing of the structure
- D.All of the above✓
Why: All of the above.
Q9. An increase in pressure altitude, temperature or mass will:
- A.Shorten the take-off distance and improve climb
- B.Lengthen the take-off distance and reduce climb✓
- C.Have no effect on performance
- D.Only affect landing distance
Why: All three raise the density altitude, and thinner air means less lift, less thrust and a lazier propeller.
Q10. A headwind component on take-off will:
- A.Increase the ground run
- B.Reduce the ground run✓
- C.Have no effect
- D.Reduce the climb gradient over the ground
Why: And it steepens the climb path relative to the ground.
Q11. Compared with both engines operating, the climb performance with one engine inoperative is:
- A.Reduced by about half
- B.Reduced by far more than half✓
- C.Unchanged
- D.Slightly improved
Why: The power halves but the airframe drag remains, so most of the surplus thrust that produced the climb disappears.
Q12. In strong winds, wind shear or turbulence, the approach speed should be:
- A.Lower than normal
- B.Higher than normal✓
- C.Exactly normal
- D.At the stalling speed
Why: The extra speed provides a margin against a sudden loss of airspeed.
Q13. Fuel burn during a long flight will:
- A.Have no effect on the centre of gravity
- B.Shift the centre of gravity, so the loading must remain within limits throughout the flight✓
- C.Always move the CG forward beyond limits
- D.Only matter if auxiliary tanks are fitted
Why: Check the aircraft stays inside the envelope at both take-off and landing weights.
