Chapter 5.4 - Airspeed, Manoeuvre and Weight Limitations

Question 1

True or False. An Aircraft is generally limited by structural criteria rather than Aerodynamic considerations or by the power available?

Answer 1

True.

When an Aircraft in flight encounters a gust, the resulting load is in addition to the Aircraft’s normal weight. What is the name of this term called?

Answer 2

Load Factor.

Question 3

Answer 3

True.

Question 4

Answer 8

• Taxiing.
• Takeoff.
• Landing.

Question 9
