- PM
- Pilot monitoring - the person responsible for monitoring the course of the flight and radio communications with ATC, flight attendants and passengers.
- Point lever
- A manually operated lever that moves the points (movable part of the track that guides rail traffic from one track to another). Points can be set at normal or reverse, dependent on what direction is required for rail traffic.
- Point levers
- A manually operated lever that moves the points (movable part of the track that guides rail traffic from one track to another). Points can be set at normal or reverse, dependent on what direction is required for rail traffic.
- Points
- Points can be in either ‘Reverse’ or ‘Normal’. Reverse is the position of points set for a less commonly used route. Normal is the position of points set for a more commonly used route, usually straight running.
- Points machines
- Machines that move points to guide trains towards either the straight (Normal) or diversion (Reverse) track.
- Pontoon boat
- A rigid-hulled collared vessel that has alloy buoyancy chambers around the periphery of the hull.
- Porosity
- A type of weld defect that refers to the entrapment of external gases in a welded joint, creating cavities, holes and pits in the weld material
- Port
- The side of a vessel that is left when facing forward
- Port Call
- Visit of a vessel to a port for operations and services
- Port pontoon
- Alloy buoyancy chamber around the periphery of the hull
- Port quarter
- The aft quadrant of the port side of the vessel
- Port state
- The country that holds jurisdiction over the port concerned
- Port State Control
- Inspection of foreign ships in national ports for compliance
- Port State Control (PSC) inspections

- Port swing
- A progressive change in heading to port or starboard
- Portable fire extinguisher
- A handheld active fire protection device usually filled with a dry chemical used to extinguish or control small fires, often in emergencies.
- Portable Pilot Unit
- A portable navigation support system specifically designed for maritime pilots
- Position
- Position refers to position in the circuit, e.g. downwind or final. Some pilots add their sequence in the circuit pattern to their radio calls to enhance situational awareness for other pilots in the circuit.
- Power generator sets
- The inspection and maintenance of the power generator set every 500 operating hours was independent of the inspection and maintenance checks of the wagon itself.
- Power supply system
- Two separate power supply systems A and B. Each system includes electrical mains power supply, reserve mains power supply, uninterruptable power supply and a backup diesel generator
- Power-connection lead
- Supplies power to the train’s electrical equipment from an onboard generator.
- PPL
- Private pilot licence
- PPL(G)
- Private pilot glider licence
- Precision approach
- Instrument approach and landing procedure using precision lateral and vertical guidance.
- Preventive risk control
- Risk controls are preventive if they stop events occurring, while mitigation controls are those that attempt to limit the extent of harm or the consequences of unwanted events.
