這實際上就是我們常說的某款飛機能否自動跟隨航道和下滑道的時候使用。
在歐洲飛通航也常用ILS和MLS但很多舊飛機未必有自動駕駛能自動跟隨。

An instrument approach performed by the aircraft autopilot, which is receiving position information and/or steering commands from onboard navigation equipment.

In general, coupled non-precision approaches must be discontinued and flown manually at altitudes lower than 50 ft below the minimum descent altitude, and coupled precision approaches must be flown manually below 50 ft AGL (above ground level).

Coupled and autoland approaches are flown in VFR (visual flight rules) and IFR (instrument flight rules). It is common for carriers to require their crews to fly coupled approaches and autoland approaches (if certified) when the weather conditions are less than approximately 4000 RVR (runway visual range).

In aviation-speak, a "coupled approach" is one that utilizes the aircraft's autopilot to navigate the aircraft in the approach phase right down to the approach minimums, and, in some cases, on to the runway itself.
