Load Factor and Stalling Speeds
100

When the weight is less than lift, the aircraft goes?

up

100

What is a chord line?

The line that connects the leading edge and trailing edge

100

The type of drag caused by the shape and surface imperfections of an aircraft is called?

parasite drag

100

According to the load factor chart, What is the load factor of an 80-degree bank angle?

5.747

200

Drag is the opposite of…?

Thrust

200

What causes more lift? (2 factors)

A bigger angle of attack and faster speed

200

The type of drag that is created as a result of producing lift is called?

Induced drag

200

Load factor is a representation of the acceleration of?

Gravity

300

What direction is pitch and what controls pitch on a fixed wing?

Up and down, elevator

300

What is an angle of attack?

The angle created by the flight path and chord line.

300

A stall occurs when an aircraft exceeds its _______, causing the wing to loose its lift. 

Critical angle of attack

300

What are the two types of stability

Static and dynamic

400

What is yaw and what controls yaw on a fixed wing?

Rotation, Rudder

400

What does Newtons 3rd Law state?

For every action there is an equal and opposite reaction.

400

During an un-accelerated flight, thrust equals what?

Drag
400

A drone pulls up sharply, generating 30 lbs of lift while weighing 15 lbs. What is the load factor, and what does it imply for structural stress?

Hint: LF=L/W

LF=2.0 — the aircraft experiences 2 G, doubling the structural load

500

What direction is roll and what controls roll on a fixed wing?

Left and right, Aileron

500

What is Bernoullis Principle?

An increase of speed of a fluid (in this case, air) occurs simultaneously with a decrease in pressure or a decrease in the fluids potential energy.

500

When an aircraft climbs at a high angle of attack, the increased pressure difference between the upper and lower wing surfaces creates stronger wingtip vortices, resulting in _____, that grows as lift increases.

Induced drag

500

When a drone initially returns to its original altitude after a disturbance, it demonstrates _______, but when it continues to oscillate and eventually settles over time, it shows_______.  

Static stability and Dynamic stability
