Drones: Loading and Performance

Front

What is the center of gravity (CG) in unmanned aircraft?

Back

The center of gravity (CG) is the point where the weight of the aircraft is balanced. It is crucial for stability and control during flight.

Front

What is the purpose of the Pilot’s Operating Handbook or UAS Flight Manual?

Back

These manuals provide essential loading instructions and operational guidelines to ensure safe flight and compliance with weight limits.

Front

What happens to the angle of attack at which an airplane wing stalls when the CG is moved forward?

Back

The angle of attack at which a wing stalls remains the same regardless of the aircraft's gross weight.

Front

What causes a stall in an unmanned airplane?

Back

A stall occurs when the wing exceeds its critical angle of attack, disrupting smooth airflow and causing a rapid loss of lift.

Front

What is the consequence of operating a small unmanned aircraft above its maximum allowable weight?

Back

Operating above maximum weight can lead to shortened endurance, affecting flight time and performance.

Front

What is maximum endurance in the context of unmanned aircraft?

Back

Maximum endurance is achieved at the point of minimum power required to maintain the aircraft in steady, level flight.

Front

Define 'critical angle of attack'.

Back

The critical angle of attack is the angle at which the wing begins to stall, resulting in a loss of lift.

Front

What is the relationship between gross weight and stall angle of attack?

Back

The stall angle of attack remains constant regardless of changes in gross weight.

Front

What is the effect of exceeding maximum allowable operating weight on maneuverability?

Back

Exceeding maximum weight typically reduces maneuverability, making the aircraft harder to control.

Front

Explain the term 'lift' in aviation.

Back

Lift is the aerodynamic force that acts perpendicular to the relative wind and supports the weight of the aircraft in flight.
