Please explain how a data link would be useful in controlling an

the same way one would for *any* aircraft that has lost communication
capability as described in AIM 6-4-1 for instance?


Please explain how aircraft that has lost (data link and all radio)
communication capability due to electrical system failure will be able
to receive the green 'cleared to land' light gun signal upon arrival
if light guns are eliminated as suggested.

Aircraft wouldn't lose the datalink because it would have a backup
battery.

That wouldn't provide the same level of safety as a ground based
system.

But if it did they could use just one color light and three or
four Morse characters which everyone would be required to memorize.
Every pilot knows S, O, A, and N (even though AN ranges have went where
VOR should have years ago, but I digress) and most people know "V" from
Beethoven's FIFTH-da-da-da-dum.

I suppose that's reasonable. It's more complex, but if we are truly a
brotherhood of airmen, I suppose we can accommodate the physically
challenged in that small way.
