Description
Circa Mid 1970's to Early 1980's (ESTIMATED)
Use Case
The 339H-1B indicator is used as part of a radar altimeter system to provide the flight crew with a visual display of the aircraft's height above the terrain during the critical approach and landing phases of flight.
- Key Functions:
- Displaying altitude on a scale (typically 0 to 2000 feet, sometimes up to 50,000 feet depending on the exact variant).
- Providing a visual alert (decision height annunciator, "DH" light) when the aircraft descends to a pre-selected decision height, a crucial safety feature for instrument landings.
