Note 1: Some IOC configurations may only provide positive ranges (0 to 65536 feet), however the EGPWS supports both
positive and negative ranges (
±
65,536 feet) for all configurations.
Note 2: This label may be provided in a configuration with a single DH input or in conjunction with a selected MDA
input. For those configurations which provide DH and MDA on separate labels format 3 applies (Format 1 is 0/0
SDI, Format 2 is Left SDI used and Format 3 is no SDI.)
SDI, Format 2 is Left SDI used and Format 3 is no SDI.)
