The Vg Diagram

Front

What is a load factor in aviation?

Back

The load factor is the ratio of the lift of an aircraft to its weight, often expressed in g's (gravitational force). It indicates the amount of stress placed on the aircraft during maneuvers.

Front

What happens to an aircraft at a load factor of -2.5?

Back

The aircraft is likely to experience structural damage due to negative load factors, which can cause stress on the airframe.

Front

What is the effect of a load factor of +2.5 at 140 mph?

Back

At a load factor of +2.5, the aircraft would likely be unharmed as this is considered normal operations.

Front

What is the significance of a load factor of 4g?

Back

A load factor of 4g indicates that the aircraft can withstand significant stress, and it would likely be unharmed as long as caution is observed.

Front

What occurs at a load factor of 0g?

Back

At a load factor of 0g, the aircraft would likely experience structural failure due to the lack of lift.

Front

What is the result of aggressive control movements at 3G?

Back

Aggressive control movements at 3G will likely cause no damage below 180 mph.

Front

What is the relationship between speed and load factor?

Back

As speed increases, the load factor can also increase, affecting the aircraft's structural integrity and performance.

Front

Define accelerated stall in aviation.

Back

An accelerated stall occurs when an aircraft exceeds its critical angle of attack, leading to a loss of lift, often during high load factors.

Front

What is structural failure in aircraft?

Back

Structural failure refers to the inability of an aircraft's structure to withstand the loads imposed on it, leading to catastrophic failure.

Front

What does 'g' stand for in load factor?

Back

'g' stands for gravitational force, and it is a measure of acceleration due to gravity, used to express load factors in aviation.
