Question 1

What are the four forces acting on an aircraft in flight?

Accepted Answer

Lift, weight, thrust, and drag

Answer

The four fundamental forces are: lift (upward, generated by wings), weight/gravity (downward), thrust (forward, from engines), and drag (rearward, from air resistance). In steady flight, these forces are balanced.

Question 2

What is Bernoulli's Principle and how does it relate to flight?

Accepted Answer

As the speed of a fluid (air) increases, its pressure decreases; this explains how airflow over a wing generates lift

Answer

Bernoulli's Principle explains that faster airflow over the curved upper surface of a wing creates lower pressure above than below, generating an upward force (lift) that supports the aircraft in flight.

Question 3

What is the purpose of flaps on an aircraft wing?

Accepted Answer

To increase lift and drag at lower speeds, enabling slower approach and landing speeds and shorter takeoff distances

Answer

Flaps extend from the wing's trailing edge to increase camber and wing area, generating more lift at slower speeds. This allows safe flight at lower approach speeds and reduces takeoff and landing distances.

Question 4

What is V1 speed during takeoff?

Accepted Answer

The critical decision speed beyond which the takeoff must be continued even if an engine fails

Answer

V1 is the speed during takeoff beyond which there is insufficient remaining runway to stop safely. Above V1, the pilot must continue the takeoff even with an engine failure, using the remaining engine(s).

Question 5

What instruments make up the 'six-pack' on a traditional flight instrument panel?

Accepted Answer

Airspeed indicator, attitude indicator, altimeter, turn coordinator, heading indicator, and vertical speed indicator

Answer

The traditional T-arrangement of six instruments provides essential flight information: airspeed, attitude (artificial horizon), altitude, turn rate, heading (directional gyro), and rate of climb/descent.
