Basic aerodynamics to stability quiz. It is designed to cover Aerodynamic Principles Chapter 3, Section B Stability. As an engineer, you will be expected to ensure that the plane you are working on is in top shape and can be stable once it is off the air. Do you think you have what it takes to tackle it? Do give it a try and refresh your memory on what we learned.
Be difficult to stall
Require less effort to control
The location of the CG with respect to the center of lift
The effectiveness of the horizontal stabilizer, rudder, and rudder trim tab.
The relationship of thrust and lift to weight and drag.
The CG shifts forward when thrust and drag are reduced
The down wash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced.
When thrust is reduced to less than weight, lift is also reduced and the wings can no longer support the weight.
A longer take off run
Difficulty in recovering from a stalled condition
Stalling at higher-than normal airspeed.
Less stable at all speeds
Less stable at slow speeds, but more stable at high speeds
Less stable at high speeds, but more stable at low speeds
Partially stalled with one wing low
In a steep diving spiral
Both wings are stalled
Neither wing is stalled
Only the left wing is stalled
Here's an interesting quiz for you.
