Definition
The segment of an instrument approach procedure between the initial approach fix (IAF) and the final approach fix (FAF), during which the aircraft is aligned and configured for the final descent to the runway. In this segment the aircraft is positioned, slowed, and stabilized so that course alignment, altitude, and configuration are correct before crossing the FAF.
Plain English
The middle part of an instrument approach. It connects the entry point of the approach to the point where the final descent to the runway begins, and it's where the pilot lines up with the course and gets the aircraft ready to land.
Context Anchor
Seen on instrument approach charts and in instrument flying discussions about the sequence of an approach to a runway.
Derivation
"Intermediate" comes from the Latin intermedius, meaning "in the middle." It sits between the initial approach (entering the procedure) and the final approach (descending to the runway), which is exactly what the name suggests.
Why Pilots Care
Ensures the aircraft is properly positioned, configured, and descending at the correct rate before entering the final approach.
Intuition Check
Do not read “intermediate” as just “moderate” or “medium difficulty.” Here it means the middle segment of a published instrument approach, before the final descent begins.
Example Sentence 1
During the intermediate approach, the pilot reduced speed and extended approach flaps before reaching the final approach fix.
Example Sentence 2
During the intermediate approach the pilot extended flaps and slowed to approach speed.
