Jan 9, 2022 at 19:48 comment added Jonathan @Jamiec I've seen the "exercise extreme caution" for alternating red and green a million times. but what exactly does that mean?? Do I hold in position, land, go around, etc, at my own discretion?
Jan 25, 2021 at 8:50 comment added Jamiec @Sean Fly the aeroplane. Land as soon as possible. Or to put it another way, aircraft dont fall out the sky because their radio stopped working
Jan 24, 2021 at 2:43 comment added Vikki @Jamiec: And what do you do if you do have a dual radio failure in full IMC?

Apr 8, 2019 at 16:19 comment added StephenS @KeithS The COMs have to be totally redundant anyway so you can use both at the same time, e.g. listening to weather updates on one while talking to ATC on the other. The NAVs have to be redundant as well since many non-RNAV instrument procedures require two VORs (or VOR+ILS) to identify fixes. The latter can share an antenna since they're receive-only, but the former couldn't transmit and receive on the same antenna at the same time, so they each must have their own.

Jul 9, 2015 at 23:04 comment added KeithS @Jamiec - ...Which is why a 172's radios aren't all in one unit; they each have the Tx/Rx circuits for their COM and NAV halves. That makes so much sense now. I assume those radios have to be totally redundant right out to the antenna?
Jul 9, 2015 at 21:40 comment added Jamiec @KeithS - If im not mistaken, one requirement to fly IMC is a backup radio - as in a whole other radio in case of malfunction.
Jul 9, 2015 at 20:52 comment added KeithS How would this work in low-vis situations like fog? I imagine that radio failure in IMC is the worst-case scenario and the tower would have little choice but to act as if the plane had requested emergency landing.

Add a link to a light gun signal video
May 9, 2014 at 15:17 comment added falstro @shortstheory I have seen a light gun in action, they're quite visible even in bright daylight.

May 9, 2014 at 14:20 comment added shortstheory Oh well, I guess I'll just post it as a question then...but thanks anyway!
May 9, 2014 at 14:19 comment added Jamiec @shortstheory - I suspect they use high intensity bulbs. Historically, sodium bulbs probably - more recently I suspect they may have gone to LED. Short answer - I don't know!
May 9, 2014 at 14:17 comment added shortstheory Now, how is the light from the light gun visible on a bright day? Aren't the window panes of ATC towers tinted? Do light guns use lasers? (but that would cause a lot more problems than it would solve I guess) :d
