If you input negative DH in the EADI or EHSI and RA stays the same, what happens to DH?

Explanation:
The display treats DH as a non-negative, valid value for instrument approach height. Entering a negative DH is outside the allowed range, so the system clears that field to indicate “not available” or invalid. The radio altitude (RA) is separate and remains unchanged because you haven’t altered the radio altitude data. So the DH field goes blank, while RA stays the same.
