Aerodynamics & Flight Principles
These are the four forces acting on an airplane in flight.
What are lift, weight, thrust, and drag?
This red line on the airspeed indicator represents the never-exceed speed.
What is Vne?
These are the four strokes of a reciprocating engine cycle.
What are intake, compression, power, and exhaust?
This condition is defined as an oxygen deficiency in the body.
What is hypoxia?
This control surface manages yaw around the vertical axis.
What is the rudder?
In straight-and-level flight, this relationship exists between the four forces.
What is lift equals weight and thrust equals drag?
After takeoff, this airspeed provides the most altitude gain in the least amount of time.
What is Vy?
Excessively high engine temperatures may cause loss of power, excessive oil consumption, and internal engine damage.
What are the effects of overheating?
This checklist is primarily used as a personal health assessment tool for pilots.
What is IMSAFE?
The elevator controls pitch, the ailerons control roll, and the rudder controls yaw.
What is true?
This principle explains why air traveling faster over the curved upper surface of an airfoil causes lower pressure on top.
What is Bernoulli’s principle?
The magnetic compass is only accurate under this flight condition.
What is straight-and-level unaccelerated flight?
If the recommended octane fuel is unavailable, this alternative may be used.
What is the next higher octane aviation gas?
A faulty aircraft heating system duct is most likely to cause this type of poisoning.
What is carbon monoxide poisoning?
During a spin to the left, both wings are in this condition.
What is stalled?
This term is defined as the angle between the wing chord line and the relative wind.
What is angle of attack?
If the pitot tube and static vents are clogged, these three instruments are affected.
What are the altimeter, airspeed indicator, and vertical speed indicator?
Pilots adjust the fuel/air mixture at altitude primarily because of this change in the atmosphere.
What is decreased air density?
This is most likely to happen between 20–70°F with high humidity.
What is carb ice?
Compared to straight-and-level flight, this maneuver increases the load factor.
What is a turn?
At this angle of attack, an airplane wing will stall, regardless of gross weight.
What is the critical angle of attack (remains the same regardless of weight)?
This colored arc on the airspeed indicator shows the normal flap operating range.
What is the white arc?
The uncontrolled firing of the fuel/air charge before normal ignition is known as this.
What is pre-ignition?
The best way to reduce the danger of spatial disorientation in poor visibility is to trust these instead of your body senses.
What are the flight instruments?
In a 60° bank, a 2,300-pound airplane must support this much load.
What is 4,600 pounds?
