Definition
In a turbojet or jet transport approach, the narrow band of airspeed and configuration parameters the pilot aims to be within when crossing a specific point on the approach — typically the final approach fix or a stabilized approach gate. Staying inside this window keeps the aircraft on a stable energy state for landing.
Plain English
A small range of speed and configuration values the pilot wants the airplane to be inside at a specific point on the approach. If the airplane is inside that range, the approach is going well. If it is outside, something needs to be corrected or the approach should be abandoned.
Context Anchor
Used when discussing approach and landing technique, especially when comparing how different airplanes require different sight pictures, speeds, or touchdown planning.
Derivation
From 'target' (the value being aimed for) and 'window' (a narrow range of acceptable values). The combination describes a defined band the pilot is trying to fly through — not a single number, but a tight range with edges.
Why Pilots Care
Staying inside the target window keeps the aircraft within safe and predictable performance limits during training and operations.
Analogy
It is like trying to park a car inside a marked parking space. You do not need to hit a single perfect inch, but you do need to be inside the acceptable space.
Intuition Check
A target window is not a cockpit window and not one perfect point on the runway. It is an acceptable zone the airplane should be in for the maneuver to stay on track.
Example Sentence 1
Crossing the final approach fix, the captain confirmed the airplane was inside the target window for speed and flap setting.
Example Sentence 2
When the bank angle drifted outside the target window the instructor called for a correction.
