Aircraft Aerodynamics and Control
ACTUAL QUESTIONS AND CORRECT
ANSWERS
Vector - CORRECT ANSWERSForce being applied in a direction.
Master Caution - CORRECT ANSWERSAlmost Critical
Master Warning - CORRECT ANSWERSCritical
CRM - CORRECT ANSWERSCrew Resource Management
Angle of incidence - CORRECT ANSWERSThe angle between the longitudinal axis of the
airplane and the chord line of the wing.
Relative wind - CORRECT ANSWERSDirection of the wind in relation to airfoil.
Angle of attack - CORRECT ANSWERSThe angle between the chord line and the relative
airflow.
Lift - CORRECT ANSWERSThe wing forces air downward and the reaction force on the
wing is proportional to lift.
Drag - CORRECT ANSWERSForce moving against the solid body in the air.
Thrust - CORRECT ANSWERSThis is developed by the propeller as it is rotated by the
engine and pulls the airplane through the air.
Weight - CORRECT ANSWERSThis is the force that is always pulling the plane
downwards.
, Parasite Drag - CORRECT ANSWERSNot associated with the production of life and
includes skin friction, form drag, and interference drag.
Induced Drag - CORRECT ANSWERSAssociated with the production of lift. That back-
pointing component of the wing reaction.
Glide Airspeed - CORRECT ANSWERSLift/Drag max = 75 KIAS in D-40
Lateral Axis - CORRECT ANSWERSControlled by elevators, thrust (engine), and pitch trim.
Longitudinal Axis - CORRECT ANSWERSControlled by ailerons (Primary) and rudder
(Secondary)
Vertical Axis - CORRECT ANSWERSControlled by rudder (Primary) and ailerons
(Secondary)
Center of Gravity - CORRECT ANSWERSThe point about which an aircraft would balance
if it were possible to suspend it at that point.
Performance Instruments - CORRECT ANSWERSAltimeter/ Airspeed Indicator/ Heading
Indicator/ Vertical Speed Indication (VSI) / Slip and Skid Indicator
Navigation Instruments - CORRECT ANSWERSNondirectional Beacons (NDBs)/ Aircraft
Direction Finder (ADF)/ VHF Omnidirectional Radio Rangefinder (VOR)/ Instrument
Landing System (ILS)/ Global Position System (GPS)
Control Instruments - CORRECT ANSWERSAttitude Indicator/ Tachometer (RPM)/
Manifold Pressure
The makeup of Atmosphere - CORRECT ANSWERS78% Nitrogen/ 21% Oxygen/ 1%
Helium and other gasses
Viscosity - CORRECT ANSWERSCauses fluid to resist flowing. Air has a low viscosity
relative to other fluid and gasses.
