Caution should be advised using glidepaths of less than 3 degrees, with large wide-body aircraft.
The threshold crossing height will be lower, and the main landing gear might well be rather close to the frangible approach light bits, as a result.
Automatic approach/land ops especially.
For example, the standard body L1011 is limited to a minimum TCH of 42 feet, for automatic A/L ops.
And yes, before anyone asks, these aeroplanes still roll-on smoothly during these automatic approach/land ops.
Nothing finer.
Now, back to normal programming...
