Definition
The TPP is an FAA publication containing the printed instrument approach procedure charts, departure procedure charts, standard terminal arrival charts, and airport diagrams used by pilots flying under instrument flight rules in the United States. It is issued in regional volumes on a 56-day revision cycle and is the official source for the charted procedures pilots fly into and out of airports in instrument conditions.
Plain English
A book of charts, published by the FAA, that shows pilots how to fly into and out of airports when they cannot rely on seeing the ground. It contains the approach charts, departure charts, arrival charts, and airport diagrams pilots reference during instrument flying.
Context Anchor
You will see TPP referenced when planning or briefing an instrument approach, a departure, an arrival, or an airport diagram.
Derivation
"Terminal" here refers to the airspace and procedures near an airport — the start and end of a flight — not a building. "Procedures" are the step-by-step charted routes pilots follow. So the name simply describes what the publication contains: the procedures used in the terminal area.
Why Pilots Care
The TPP supplies the current, legally usable procedures required for safe instrument flight.
Intuition Check
Do not read “terminal” here as a passenger building or a computer screen. In this term, “terminal” means the airspace and operations near an airport.
Example Sentence 1
Before the flight, the pilot pulled up the current TPP volume to brief the instrument approach into the destination airport.
Example Sentence 2
Changes to the TPP are issued every 56 days and must be reviewed before any IFR flight.
