1. The sequence of activities during the project phase of an aircraft broadly includes: a. "preliminary sizing" and b. "conceptual deign".

2. The load factor is generally calculate as: load factor = offered payload / sold payload

3. The conventional aircraft configuration is characterized by an empennage at the rear of the aircraft.

4. The equation used to estimate the maximum take-off mass is known as the "first law of aircraft design" in the Aircraft Design lecture at HAW Hamburg.

5. A retractable landing gear folds away during the flight to reduce drag.

6. A flaps is a high lift device used to increase the lift on the aircraft's wing.

7. Slats allow the wing to operate at a higher angle of attack.

8. An aircraft engine is a piston engine, a gas turbine or an electric engine.

9. A vertical tail is intended to reduce side slip and provide directional stability.

10. A spoiler is a device to increase the lift of a wing.
