Glossary "G7"

NONTOWERED AIRPORTS
An airport without an operating control tower.

NOTAM (NOTICE TO AIRMEN)
A notice containing information concerning facilities, services, or procedures, the timely knowledge of which is essential to personnel concerned with flight operations.

OPERATING LIMITATIONS
Limitations published by aircraft manufacturers to define limitations on maneuvers, flight load factors, speeds and other limits. Presented in the aircraft in the form of placards and printed in the limitations section of the aircraft flight manual.

OVERSHOOTING
The act of over flying an intended spot for landing or flying through a course intended for intercept.

PARAFOIL
See RAM-AIR WING.

PARALLEL RUNWAYS
Two or more runways at the same airport whose centerlines are parallel. In addition to runway number, parallel runways are designated as L(left) and R(right) or if three parallel runways exist, L(left), C (center) and R(right).

PARASITE DRAG
That part of total drag created by the design or shape of PPC parts. Parasite drag increases with an increase in airspeed.

PART 1
Federal Aviation Regulation from 14 CFR, pertaining to definitions and abbreviations of terms.

PART 61
Federal Aviation Regulation from 14 CFR, pertaining to the issuance of pilot and instructor certificates and ratings.

PART 67
Federal Aviation Regulation from 14 CFR, pertaining to medical standards and certification for pilots.

PART 91
Federal Aviation Regulation from 14 CFR, pertaining to general operating and flight rules.

PATTERN ALTITUDE
The common altitude used for aircraft maneuvering in the traffic pattern. Usually 1,000 above the airport surface.

PENDULUM
A body so suspended from a fixed point as to move to and fro by the action of gravity and acquired momentum.

Pendulum Effect
The characteristic of the cart weight hanging below the wing that stabilizes the wing pitching moment and the cart underneath the wing for unaccelerated flight. This cart weight (pendulum) can also create momentum of the cart rotating around the wing.

 

 

PERSONALITY TENDENCIES
Personal traits and characteristics of an individual that are set at a very early age and extremely resistant to change.

P-FACTOR
A tendency for an aircraft to yaw to the left due to the descending propeller blade on the right producing more thrust than the ascending blade on the left. This occurs when the aircraft’s longitudinal axis is in a climbing attitude in relation to the relative wind. The P-factor would be to the right if the aircraft had a counterclockwise rotating propeller.

PILOTAGE
Navigational technique based on flight by reference to ground landmarks.

PILOT IN COMMAND
The pilot responsible for the operation and safety of an aircraft.

PILOT’S OPERATING HANDBOOK (POH) A document developed by the aircraft manufacturer and contains the FAA approved Aircraft Flight Manual (AFM) information.

PITCH
The rotation of a PPC about its lateral axis.

PITCH ANGLE
The angle between the wing and the horizontal plane of the earth.

PITCH ATTITUDE
The angle of the longitudinal axis relative to the horizon. Pitch attitude serves as a visual reference for the pilot to maintain or change airspeed.

PLACARDS
Small statements or pictorial signs permanently fixed in the cockpit and visible to the pilot. Placards are used for operating limitations (e.g., weight or speeds) or to indicate the position of an operating lever (e.g., landing gear retracted or down and locked).

PLANFORM
The shape or form of a wing as viewed from above. It may be long and tapered, short and rectangular, or various other shapes.

POH
See PILOT’S OPERATING HANDBOOK.

PORPOISING
Oscillating around the lateral axis of the aircraft during landing.

Porpoising Effect
The rapid increase in throttle resulting in a rapid initial pitch up, which results in the pendulum effect that dampens out into a steady state climb.

POSITIVE DYNAMIC STABILITY
The tendency over time for an aircraft to return to a predisturbed state.

POSITIVE STATIC STABILITY
The initial tendency to return to a state of equilibrium when disturbed from that state.

POWERED PARACHUTE (PPC)
A powered aircraft comprised of a flexible or semi-rigid wing connected to a fuselage (cart) so that the wing is not in position for flight until the aircraft is in motion. The fuselage of a powered parachute contains the aircraft engine, a seat for each occupant and is attached to the aircraft’s landing gear.
