Stuck Microphone
« on: January 20, 2015, 08:57:58 PM »
If you are on a controllers frequency and all of a sudden you can’t get through because there is a stuck microphone on the frequency what would happen if you used another frequency temporary such as the ground controllers frequency for tower operations or even the clearance deliver frequency. how come the FAA never assigned a backup frequency in such cases or even in an emergency that would be published? Especially in class B airspaces! A Stuck microphone has got to be annoying.

A.K.A. that frequency you were likely monitoring (except perhaps in terminal airspace) anyway, right? :)

Even if you weren't, there's a very good chance ATC is. From AIM § 6-3-1(h)(1):
Quote
121.5 MHz is guarded by direction finding stations and some military and civil aircraft. 243.0 MHz is guarded by military aircraft. Both 121.5 MHz and 243.0 MHz are guarded by military towers, most civil towers, FSSs, and radar facilities.

Personally, I'd probably just try another frequency from the same facility first. For example, if you're with approach, I'd look for another frequency even if it's for a neighboring chunk of airspace. Chances are the person I reach is sitting pretty close to the person I couldn't reach. If it's for tower, then I'd try a different tower frequency (North vs. South, Helicopter, etc.) or even a ground frequency.

Yep standard to have 121.500 up on #2 radio (in cruise). Your plan works too, if you're familiar with the frequencies.

Speaking about stuck mikes. They seem to be fairy common with aircraft radios. Don't they have an
indicator light or symbol on the radio to indicate the radio is transmitting even when it shouldn't be?
Or is it just a case of the pilot not noticing it until ground controller or other aircraft mentions there is
a stuck mike on the frequency?

You can't "notice it" as a result of someone mentioning it on frequency, because your radio is not receiving on frequency as long as the mic is stuck and the radio is transmitting.

Sorry. I was not clear. I meant if there is an indicator light or symbol on the radio panel to show
the radio is transmitting wouldn't the pilot notice that, not that he would hear on the radio about a
stuck mike on frequency. As you say, he couldn't hear transmissions if the might is stuck.

In the case of the Garmin radios (G1000, etc.), the only indication is a small "TX" next to the frequency on the screen.  It doesn't stand out in any way, and it's easy to miss if you're not specifically looking for it.  On older audio panels, there is usually a small light, although I remember in the Cherokee I used to fly, the pilot's view of light was blocked by a knob on the audio panel...

Nifty stuck mic feature on the g1000 and other garmin radios. If you have a stuck mic and transmit continuously for 35 seconds it will cut your mic off.

Oh yeah, I forgot about that!  Also know as "automatic long-winded pilot squelch"  :-D

Except then you have to listen to the Guard nazis.  I swear, some pilots just need to chill out.  I've listened before where another controller asked a pilot to try an aircraft on guard and as soon as he did, a bunch of people yelled "On Guard!"  I was happy that the pilot finally said back, "Yeah, I know...I'm trying to do a favor for ATC, is that okay with you?"
