Definition
The portion of an instrument approach procedure that lies between the initial approach fix (IAF) and the final approach fix (FAF). It positions the aircraft on the proper course, at an appropriate altitude and airspeed, to begin the final approach.
Plain English
The middle part of an instrument approach. It connects the start of the approach to the final descent toward the runway, and it is where the aircraft gets lined up, slowed down, and stepped down to the right altitude before final.
Context Anchor
Seen in instrument approach procedures and course-reversal discussions, including teardrop procedures, where the aircraft turns inbound and prepares to begin the final approach.
Derivation
From Latin intermedius, meaning 'in the middle.' The name reflects its position: between the initial and final segments of the approach.
Why Pilots Care
Knowing exactly where the intermediate segment begins and ends helps pilots manage descent rates, configure the aircraft, and maintain proper alignment before entering the final approach.
Intuition Check
Do not read intermediate segment as just any “middle part” of flying. In an instrument approach, it is a specific published portion of the procedure with a defined role before final approach.
Example Sentence 1
On the intermediate segment, the pilot reduced speed and lowered approach flaps before reaching the final approach fix.
Example Sentence 2
The pilot verified the altitude restriction at the start of the intermediate segment before continuing the approach.
