Principles of Flight - QT

Lesson Quicktakes cover the items that should be memorized from each of the wifiCFI Lessons. They do not cover all of the lesson details in-depth.

FOUR FORCES OF FLIGHT:

1. Lift

2. Weight

3. Thrust

4. Drag

LEFT TURNING TENDENCIES:

1. P-Factor

2. Torque

3. Gyroscopic Precession

4. Spiraling Slipstream

PRODUCING LIFT:

• Bernoulli’s Principle = An increase in the speed of a fluid (air) is accompanied by a decrease in pressure.

• Downwash Principle = Air deflected off the trailing edge of the wing.

TYPES OF DRAG:

• Parasite Drag = No way functions in the aid of flight.

• Form Drag = Shape of the aircraft.

• Interference Drag = Intersections of aircraft components.

• Skin Friction Drag = Skin is not perfectly smooth.

• Induced Drag = It is a by-product of lift.

WINGTIP VORTICES:

WAKE TURBULENCE:

• Avoidance on Takeoff = Rotate prior to the preceding aircraft. Stay above preceding aircraft’s flight path or side-step.

• Avoidance on Landing = Stay above preceding aircraft’s flight path. Land further down the runway.

LIFT/DRAG RATIO:

GROUND EFFECT:

AIRPLANE AXES:

AIRCRAFT STABILITY:

Static Stability:

Dynamic Stability:

FORCES IN TURNS:

SLIPPING AND SKIDDING TURNS:

Remember to "step on the ball."

ADVERSE YAW:

Remember to "step on the ball."

LOAD FACTOR:

THE VG DIAGRAM:

VA (MANEUVERING SPEED)

• Below Va Speed = The aircraft will stall.

• Above Va Speed = The aircraft may suffer structural damage.

• Heavier Aircraft = Awarded a Higher Maneuvering Speed.

• Lighter Aircraft = Suffer a Lower Maneuvering Speed.
