FAA Private Pilot Airplane (PAR) flashcards

In a METAR, 'FZRA' indicates freezing rain, a severe weather hazard due to the rapid accumulation of clear ice on aircraft surfaces.

• FZRA = Freezing Rain.
• Causes rapid accumulation of clear ice.
• Often results in severe airframe icing.
• Extremely dangerous for aircraft.

Memory trick: METAR P-Codes: 'RA' is rain, 'SN' is snow, 'FZ' means 'Freezing' danger!

Jet streams are narrow bands of strong winds in the upper troposphere, characterized by significant temperature gradients and wind shear.

• Located at high altitudes (tropopause level).
• Associated with strong horizontal temperature gradients.
• Causes significant wind shear, leading to clear air turbulence (CAT).

Memory trick: Jet stream is a 'High-Speed Highway' with 'Turbulent Shoulders'.

A landing direction indicator, often a large 'T' or tetrahedron, indicates the preferred runway for landing and takeoff at airports without an operating control tower, overriding other wind indications.

• Located within the segmented circle.
• Indicates the runway to use for landing and takeoff.
• The stem of the 'T' or tetrahedron points into the wind and indicates the landing runway.
• Overrides wind sock/cone if different, as it's the airport's chosen direction.

Memory trick: The 'T' tells you where to land, and the wind just whispers.

A tailwind increases an aircraft's ground speed during landing, which significantly increases the required landing distance and reduces the pilot's control authority.

• Increases ground speed during approach and rollout.
• Significantly increases landing distance.
• Reduces effective airspeed over control surfaces at a given ground speed (relative to no wind).
• Can make go-arounds more challenging due to reduced climb performance relative to ground.

Memory trick: Headwind Helps, Tailwind Hurts.

Moving weight within an aircraft changes its center of gravity. The amount of CG shift depends on the weight moved and the distance it's moved.

• CG shift = (Weight moved × Distance moved) / Total weight.
• If weight moves forward, CG moves forward.
• If weight moves aft, CG moves aft.
• Used to adjust CG to be within limits without changing total weight.

Memory trick: Move Weight, Shift CG: Moment change, divide by total.

The process of determining the aircraft's weight at the point of landing by subtracting the estimated fuel burn from the takeoff weight.

• Must not exceed the maximum allowable landing weight.
• Fuel consumption is a primary factor.
• Ensures structural integrity during landing.

Memory trick: Weight Down, Fuel Out, Stay Safe.

A pre-flight briefing provides pilots with essential information for a safe flight, including weather, NOTAMs, and airspace restrictions.

• Required for all flights.
• Can be obtained from FSS or approved online sources.
• Covers weather, NOTAMs, TFRs, and airport information.

Memory trick: Always call FSS for a comprehensive flight safety check.

A pre-takeoff check to ensure both ignition systems (magnetos) are functioning correctly by momentarily operating the engine on each magneto individually.

• Performed during engine run-up.
• Expect a slight RPM drop when switching from 'BOTH' to 'LEFT' or 'RIGHT'.
• Excessive RPM drop or no drop indicates a problem.

Memory trick: Magneto Checks Reveal Power Differences.

Graphical representations on aviation charts that convey information about airports, including their type, services, and operational status.

• Blue symbols indicate airports with control towers.
• Magenta symbols indicate airports without control towers.
• Runway length and surface type are also depicted.

Memory trick: Blue means Busy, Magenta means Mellow (no tower)

The process of converting a true course (relative to true north) into a compass heading (what the aircraft's magnetic compass should read) by accounting for magnetic variation and compass deviation.

• True Course (TC) is relative to True North.
• Magnetic Course (MC) is relative to Magnetic North.
• Compass Heading (CH) is what the compass shows, accounting for local magnetic fields.

Memory trick: True Virgins Make Dull Company (add or subtract)

The loss of electrical power from both the alternator (or generator) and the battery, rendering all electrical components inoperative.

• Affects electrically powered systems only.
• Pitot-static instruments and magnetic compass are unaffected.
• Gyroscopic instruments may be vacuum or electrically powered.

Memory trick: Electric, Vacuum, Pitot-Static are the Three Instrument Power Types.

A designated geographical location on a sectional chart where pilots can perform an in-flight accuracy check of their VOR receiver.

• Depicted by a 'V' symbol with an arrow pointing to the VOR.
• Includes the radial and distance from the VOR, and sometimes the designated altitude.
• VOR accuracy must be within +/- 6 degrees for airborne checks.

Memory trick: V-shaped for VOR-ifying in flight

A comprehensive weather and aeronautical information briefing provided by a Flight Service Station (FSS) briefer, tailored to a specific flight plan.

• FSS briefers are trained to provide all necessary pre-flight information.
• Briefings can be standard, abbreviated, or outlook.
• Includes adverse conditions, VFR flight not recommended, NOTAMs, TFRs, and more.

Memory trick: Briefers are Best for Broad Briefings

Class B airspace boundaries are depicted on sectional charts using solid blue lines, indicating controlled airspace around the nation's busiest airports.

• Solid blue lines define lateral boundaries.
• Altitudes are shown as fractions (e.g., 100/SFC).
• Requires ATC clearance to enter.

Memory trick: Blue is for Big and Busy, like Class B airport traffic.

A malfunction where the pitot tube (which measures ram air pressure) becomes obstructed, primarily affecting the airspeed indicator.

• Airspeed indicator reads low or zero.
• Altimeter and VSI usually unaffected.
• Can be caused by ice, insects, or debris.

Memory trick: Pitot is Speed, Static is Altitude.

The pilot's adjustment of the fuel-air ratio to compensate for changes in air density, primarily leaning for increased altitude.

• Air density decreases with altitude.
• Leaning reduces fuel flow to match less air.
• Prevents rich mixture, spark plug fouling, and power loss.

Memory trick: Lean High, Rich Low, Keep it Flow.
