P Flashcards
Parallels
Lines of Latitude
Parasite drag
Drag caused by the friction of air moving
over the aircraft structure; its amount varies directly with
the airspeed.
Payload (GAMA)
The weight of occupants, cargo, and baggage.
Personality
The embodiment of 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.
Phugoid oscillations
Long-period oscillations of an
aircraft around its lateral axis. It is a slow change in pitch
accompanied by equally slow changes in airspeed. Angle
of attack remains constant, and the pilot often corrects for
phugoid oscillations without even being aware of them.
Pilotage
Navigation by visual reference to landmarks
Pilot In Command (PIC)
The pilot responsible for the operation and safety of an aircraft.
Pilot Report (PIREP)
Report of meteorological phenomena encountered by aircraft.
Pilots Operating Handbook/Airplane Flight Manual (POH/AFM)
FAA-approved documents published by the
airframe manufacturer that list the operating conditions for
a particular model of aircraft.
Pilot pressure
Ram air pressure used to measure airspeed
Pilot-static head
A combination pickup used to sample pilot pressure and static air pressure.
Plan view
The overhead view of an approach procedure on
an instrument approach chart. The plan view depicts the routes
that guide the pilot from the en route segments to the IAF.
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.
Pneumatic
Operation by the use of compressed air
Point-in-space approach
A type of helicopter instrument
approach procedure to a missed approach point more than
2,600 feet from an associated helicopter landing area.
