Definition
An FAA publication containing the official 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. The TPP is organized by geographic region into bound booklets and is updated on a 28-day cycle to keep procedures current.
Plain English
A regularly updated booklet of charts that show pilots exactly how to fly into and out of airports when they are using instruments instead of looking outside. It also includes diagrams of the airport itself.
Context Anchor
You will see this term when planning an instrument flight, reviewing airport procedures, or checking whether procedures are still published for an airport.
Derivation
"Terminal" here means the airport area where flights begin or end, not a building. "Procedures" refers to the step-by-step routes and altitudes pilots must follow. So the name simply means "the book of step-by-step charts for the airport area."
Why Pilots Care
These charts directly show whether an airport is closed indefinitely and provide the current procedures required for safe IFR operations.
Intuition Check
Do not read terminal as only the passenger building at an airport. Here, terminal means the airport-area part of flight where arrivals, departures, and approaches are flown.
Example Sentence 1
Before the flight, she pulled up the current TPP charts to brief the instrument approach into her destination.
Example Sentence 2
A note on the TPP charts indicated the airport was closed indefinitely.
