Technical Specific · DGCA CPL. The correct option is marked on each.
Q1. The wing span of the DA-42 NG is:
- A.11.54 m
- B.12.34 m
- C.13.42 m✓
- D.14.32 m
Why: About 44 ft. Measured over the wingtip lights it is 13.55 m (44.5 ft).
Q2. The overall length of the aircraft is:
- A.8.56 m✓
- B.9.25 m
- C.7.94 m
- D.10.10 m
Why: 28 ft 1 in.
Q3. The overall height of the aircraft is:
- A.2.19 m
- B.2.49 m✓
- C.2.95 m
- D.3.15 m
Why: 8 ft 2 in, measured to the top of the T-tail.
Q4. The wing area is:
- A.12.69 m²
- B.13.96 m²
- C.14.69 m²
- D.16.29 m²✓
Why: 175.3 sq ft.
Q5. The aspect ratio of the wing is:
- A.10.05
- B.11.02
- C.11.06✓
- D.12.05
Why: A high aspect ratio, which is why the aircraft has low induced drag and a good glide and climb.
Q6. The dihedral angle of the wing is:
- A.3°
- B.4°
- C.5°✓
- D.6°
Why: Dihedral gives lateral (roll) stability.
Q7. The leading edge sweep of the wing is:
- A.0°
- B.1°✓
- C.3°
- D.5°
Why: Essentially a straight wing.
Q8. The mean aerodynamic chord (MAC) is:
- A.1.271 m✓
- B.1.735 m
- C.2.196 m
- D.0.660 m
Why: 4 ft 2 in.
Q9. The angle of incidence of the horizontal tail, relative to the longitudinal axis, is:
- A.+1.1°
- B.−1.1°✓
- C.+1.2°
- D.−1.2°
Why: Negative (leading edge down) to produce the download that gives longitudinal stability.
Q10. The rudder area is:
- A.0.24 m²
- B.0.66 m²
- C.0.78 m²✓
- D.2.43 m²
Why: The complete vertical tail is 2.43 m²; the elevator and the two ailerons are 0.66 m² each.
Q11. The wheel base of the landing gear is:
- A.1.365 m
- B.1.535 m
- C.1.735 m✓

Why: 5 ft 8 in. The track (distance between the main wheels) is 2.95 m.
Q12. The fuselage of the DA-42 NG is of which construction?
- A.Semi-monocoque composite✓
- B.Full monocoque aluminium
- C.Truss type
- D.Warren girder
Why: Carbon-fibre reinforced plastic, not riveted metal.
Q13. The number of propeller blades fitted to each engine is:
- A.1
- B.2
- C.3✓
- D.4
Why: Three-blade, constant-speed, fully feathering propellers.
