Knowledge Test Flashcards
ANDS
Accelerate North, Decelerate South - on EW trajectory. No error on NS. Compass will show a turn to the North if you accelerate on an EW trajectory. Turn to the S if you decelerate on an EW trajectory.
NOSE
North Opposite, South Exaggerated. During turn from northerly or southerly heading.
Heat does what to the altimeter?
Pressure level is raised in terms of altitude, altimeter will measure a higher pressure at a lower altitude. Indicated altitude will be lower than true altitude on warm days.
Gyroscopic Instruments
Heading, attitude, turn coordinator
Pitot Static
Altimeter, VSI and airspeed (pitot)
What makes an airplane turn?
Horizontal component of life. Some of the lift is now working to turn the airplane, less upward lift.
Why does the nose pitch down with reduced power?
Less air over plane, decreases the elevator’s effectiveness
Why does an airplane descend during a turn?
Increased load on the wings due to centrifugal force. Amount of increased load depends on the speed of airplane, caution between too fast to put too much load during a turn and going below the increased stall speed during a turn.
Stall during a turn
Higher stall speed; as load factor increases, stall speed increases.
As bank angle increases, AOA needs to increase to create more lift.
How to calculate load factor?
Use chart, enter angle of turn and determine G factor. Times G factor by weight of aircraft. Load is given in lbs.
What is P Factor?
Caused by the pitch of the prop. Each blade has a chord line and an AOA, but the right has more thrust than the left. At high AOA, the plane will turn to the left
Torque Effect - when greatest?
High power
Low airspeed
High AOA
Manufacturer built in ways to battle - slightly bigger AOA on left wing, tail a bit to the right.
V le
Max velocity can fly with Landing gear Extended
Vx
Best angle of climb speed - altitude over distance
Vy
Best rate of climb - altitude over time
How to handle severe turbulence
Maintain maneuvering speed or below Va (note: Va is not marked on airspeed indicator). Highest speed that does not create undue stress on airplane
Fly at level flight
Allow minor changes to airspeed and altitude. Do not chase the airspeed
Va
Maneuvering speed - a single flight control can be at its greatest deflection without risk of damage to the aircraft.
Vno
Max structural cruising speed. Anything above light turbulence above this speed could cause structural damage to the plane.
Vne
Never exceed speed. Shown by the red radial line. Max speed plane can be flown in calm air, but risk of structural damage if turbulence hits.
Vfe
Top speed with flaps extended
Vso
Power-off stall speed in landing condition (flaps and landing gear extended). Lower limit of white arc.
Caution Range
Vno to Vne
Wingtip Vortices
Air moves around edge of wing to go to low pressure. Creates vortex going out and then back towards the plane on both sides.
Stronger at high AOA and when creating lift.
Strongest when airplane is heavy, clean (no flaps) and slow
Avoid by approaching above glide path and landing beyond. Takeoff before and turn upwind.
Ground Effect
Interference of the Earth’s surface with the airplanes airflow patterns. Ground keeps the air from going over the tip of the wing. Allows the airplane to fly better.
Increases lift, decreases drag.
Problems with Ground Effect
Can become airborne before reaching recommended takeoff speed
Floating - if have increased speed, due to decreased drag in GE, will float long distance along the runway if less than one wingspan above the runway.

Communications in Class C
- Require Mode C Transponder/Altitude encoding and two way communications (4096 or Mode S)
Same as Class D - Must establish two way comms before reaching the 10NM radius (20NM radius is the procedural area, should establish there) but do not need clearance. ATC must say call sign.

Rotating beacon during day at airport means?
Weather is below VFR minimums
VFR minimums at an aiport
3SM ground visibility
1,000 ceiling AGL
Parameters of special VFR clearance at airports
- 1 SM viz and clear of clouds during day
- Night - require IFR equipped and rated
ATC will then separate aircraft (like IFR), because weather conditions are less than the minimums. ATC will not offer or encourage, but can provide if requested and has time.
Where can you find additional information about restricted areas?
Legend of chart in ‘Special Use Airspace Areas’
Who can grant special VFR clearance to land at an airport?
Class E - Air Route Traffic Control Center
Class D-B - ATC
Exceptions to basic VFR Minimums
- Uncontrolled (G) at night within .5M of airport. Still need 1SM viz and clear of clouds
- Class B = 3M viz, clear of clouds
Other exceptions must be requested from ATC or Air Route Traffic Control.
What is in a restricted area?
Unusual, hazardous, often invisible. Artillery, guided missiles. Must have clearance from controlling agency, or if the chart depicts times when it is not restricted.

ATC and General Operating Rules
Aux electric fuel pump - when can use?
Redundancy if engine driven pump fails. Use during TO and L
Constant Speed Prop. What to avoid? How is it changed?
Change the angle of the prop to adjust pitch for best performance.
Avoid high manifold pressure with high RPM.
Changed by a governor.
What does a throttle do?
Regulates power output. Changes the amount of air and fuel going into the intake manifold.
How to adjust mixture when changing altitude
Lean going up - air is less dense, fewer molecules per unit of volume. Need ‘more air’ to mix with fuel. If mixture is too rich, engine will run rough.
Increase going doing for opposite reason
Mixture changes the ‘weight’ of the fuel and air
What causes carburetor icing?
Pressure differential between the venturi throat and the air inlet.
Conditions favorable to carb icing?
20-70 F, high humidity.
Float type is more susceptible to icing than fuel injection system.
What happens to RPM when apply carb heat?
Decrease in RPM because hot air going into engine (hot air is less dense, mixture is momentarily too rich). As ice melts, RPM increases. Adjust mixture as needed.
What causes engine overheating?
- Mixture too lean
- Operating with too much power
- Using fuel that has a lower than specified fuel rating
How to cool engine mid-flight if overheating?
Add fuel (fuel carries away heat)
Decrease rate of climb, pitch nose down (more air over engine)
Increase airspeed (more air over engine)
How is an engine cooled?
Oil - carries away heat. If not enough oil, the oil temp will be too high
Air cooled but not sufficient without oil
What happens if an engine overheats?
- Loss of power
- Excessive oil consumption
- Potential permanent internal engine damage
What is detonation and how to respond?
Unburned charge in cylinder explodes instead of burning normally. Can be caused by using a fuel of a lesser grade than specified. NOTE: Can use a fuel of a higher grade than specified.
Lower nose and pull back on throttle
What is pre-ignition and how to respond?
Fuel air charge fires in advance of the normal spark ignition.
Need mechanic.
What does haze do in terms of vision?
Makes traffic and terrain seem farther away than it is.
How to scan for aircraft
Right to left, 10 degree sections of the sky
How to scan for aircraft at night
Use peripheral vision. Slowly scan, off center viewing. Avoid looking white lights or strobes.
For enhanced visibility, what does FAA recommend regarding daytime lights?
Use landing lights whenever below 10,000’. Voluntary, but especially during periods of reduced visibility.
What to do in a Near mid-air collision (NMAC), and distance of one.
500’
