I'm not sure, but for one aircraft I made an extension cord of 50 feet. This was for maintennace purposes, allowing me to plug into one external jack point, and crawl around inside the tail, or go up on a scissor lift to the tail. The only practical limit is the hassle of dragging the wire around.

Quoting HAWK21M (Thread starter): Is there any official Doc to suggest the standards for the Ground headset cable length required while connecting from Ground Maintenance to the Flight deck.
Hi, I am a ham radio guy, and have wondered why use corded headsets at all ? you already carry a walkie-talkie on some frequency, why not request an RF adapter (Audio IN, Audio Out, modulator, RF transceiver) to plug in the socket for the audio. That way, the ground operator can be free to do whatever within a certain range (say 100 feet) of the aircraft on a 9 volts battery.
or, you could cheat and use a low cost blue tooth/audio converter for two-way conference in an interference free spread spectrum band that is "free to use" in almost all parts of the globe and also in the S. Asian regions.
I just did a random search and found some gadget, there are probably thousands of such variations or you can build your own...
Think of the issues with "no wire" connecting ground op and the aircraft.. essentially the "headset" would have to be bluetooth compatible, or if bluetooth is not allowed, then it should have an integrated VHF transceiver.
The noise on the ramp is pretty loud, especially when you are 25 feet from two or more jet engines starting. Also, since it is "intercom" and never leaves onto an open frequency, your ground operators don't need a radio license or have to put their transmissions between other aircraft and ground crews on frequency.
Yeah, when everythings shut down a normal hand held radio would be fine, but when you're giving them a start once you have the engines running you pretty much need the fancy mouthpiece that goes around your face to help block the noise. Also plugging in puts you direct to the flight deck, no waiting for the radio to be free.

I'd love some type of wireless or radio device so I could talk to the ground crew, however, there would be some issues that would have to be solved, such as having to monitor and select between a ramp control and ground personnel frequency during pushback and engine start, which is a pretty busy time.
Plus, I'm sure any kind of radio intercom device would have to be "approved" by the appropriate government authorities and thus would be much more expensive than a regular cord simply because it an official sticker on it.
For the time being, I'm thinking the simpler, cable route will be the better choice.

That would require to aircraft "sync" up every time it approaches a gate or leaves the gate. If a plane is sitting at a gate, which is right next to 2 other gates, and those two gates are right next to 4 other gates, how difficult would it be for that single plane to "sync" up to its intended gate? And how hard would it be for that aircraft to "sync" up to different gates where ever it flies to?
Quoting JAGflyer (Reply 4): Have the pilots tune to an empty frequency or 123.45 and talk to them that way?
How many planes do you think push back at the same time at a busy airport? One? There can be more than 10 or 20 aircraft pushing back at the same time at a busy airport in the morning. It would be expensive to establish a single frequency for each gate. And that could lead to confusion over which frequency to monitor when.

I've used it for troubleshhoting systems. For example, the Dash is famous for airconditioning snags. The headset is great because it blocks out the noise of the APU or packs, and lets you observe the pack valve response to commands from the cockpit.

Quoting HAWK21M (Reply 16): There is a coiled wired type headset available similiar to the Telephone cable that expands when stretched & takes less space normally.
We primarily use the coiled ones. IIRC, we procure the 25 foot coiled ones for most of our operations. There are also 2 combinations that you can have. Either you have a push-to-talk headset with a non-push-to-talk cord, or the other way around. I can't remember which one we went with, but I think it was a push-to-talk cord because the cord is cheaper to repair/replace.
