- Monocoque Structure.
-Semi-monocoque Structure.
Main flight control surfaces include? Elevators, Ailerons, Rudder.
, Name three secondary flight controls. Flaps, Slats, Spoilers.
Nosewheel steering in light airplanes is usually Control rods or cables operated by the rudder pedals.
operated by
Bernoulli's Principle states that as velocity increases, Decreases
pressure
Induced Drag is created by producing Lift
Name the three types of Parasite Drag: Form Drag, Interference Drag, Skin Friction Drag
Name two types of flaps Plain, Split.
An airplane can be stalled at any airspeed, any weight Critical
and any attitude. When it stalls we have exceeded the
_ _____angle of attack.
Exceeding the angle you named in the previous Separation of Airflow
question causes ______ over the top of the wing:
Name three axes of flight, and the control surfaces that Longitudinal (roll) = Ailerons
affect them. Lateral (pitch) = Elevator
Vertical (yaw) = Rudder
Which statement relates to Bernoulli`s principle? Air traveling faster over the curved upper surface of an airfoil causes lower
pressure on the top surface.
The term 'angle of attack' is defined as the angle between the wing chord line and the relative wind.
What is the relationship of lift, drag, thrust, and weight Lift equals weight and thrust equals drag.
when the airplane is in straight-and-level flight?
What is one purpose of wing flaps? To enable the pilot to make steeper approaches to a landing without
increasing the airspeed.
Which pressure is caused by motion? Dynamic pressure
The left turning tendency of an airplane caused by P- Propeller blade descending on the right, producing more thrust than the
factor is the result of the ascending blade on the left
A constant-speed propeller has a variable pitch angle True
and is efficient over a wide range of RPM and airspeed
conditions?
What effect does extending the flaps have on the Increases camber
camber of the wing?
Bernoulli's Principle states that as velocity increases, Decreases
pressure _____ _.
Induced Drag is created by producing _______ _. Lift
