Candidate Questions & Verified Aviation/Quantitative
Solutions
Dihedral effect - correct answer the amount of roll moment produced per
degree of sideslip is called dihedral effect
Downwash - correct answer air that is deflected perpendicular to an
airfoil's motion
Drag curve - correct answer a constructed image of the amount of aircraft
drag at different speeds
Dynamic stability - correct answer describes the tendency of the aircraft
after it has been disturbed from straight and level flight to restore the
aircraft to its original flying condition
Drag coefficient - correct answer a dimensionless quantity that represents
the drag generated by an airfoil of a particular design
Directional stability - correct answer the aircraft's initial tendency about its
yaw (Vertical Axis)
Equilibrium - correct answer the aircraft's state when all opposing forces
acting on it are balanced. Resulting in unaccelerated flight at a constant
altitude
, Feathering properller - correct answer controllable pitch propeller that can
be rotated sufficiently by the pilot so that the blade angle is parallel to the
line of flight, minimizing drag
Forward slip - correct answer pilot controlled maneuver where the
aircraft's longitudinal axis is inclined to its flightpath
Glide ratio - correct answer ratio between altitude lost and distance
traversed during non powered flight. (how far you have fallen and how far
you have moved forward while gliding)
Glidepath - correct answer an aircraft path's across the ground when
approaching to land
Gross weight - correct answer the air crafts total weight when it is fully
loaded
Gyroscopic precission - correct answer the attribute of rotating bodies to
manifest movement ninety degrees in the direction of rotation from the
point where force is applied to the spinning body
Heading - correct answer the direction that the aircraft's nose is pointed
Inertia - correct answer a body's opposition to a change of motion
Internal combustion engine - correct answer a mechanical device that
produces power from expanding hot gases created by burning a fuel-air
mixture within the device
