Is there any real difference between flying in the U S and England for gen av pilots? Do David Clark headsets work with whatever radio frequency they have there?
Thanks.
I once flew gliders there and it was similar, but they fly a very close pattern with no real downwind. If I went on DW past the end of the runway like here, they called it "flying away from the runway". They wanted you to turn base at the end of the runway.
They will, unless the sender has a *very* squeaky voice. :-)Quote:

Sorry Bill, you're SOL with the David Clarks. Only Bose, Lightspeed, ASA and Kore pick-up British radio frequencies. :>)Quote:

Pretty much the same as here. I spent a lot of time all over England in 2003. Took my logbook with me to log some UK time. Flew out of Old Sarum airfield near Salisbury. Altimeter is in millibars and they use QNE and QNH for consistency. Each small field has a small tower about 20’ tall basically for only takeoff and landing clearance. Not even close to class D.
Thanks Carl for your straight answer. Aren't those other guys cute?
Thank you, thank you, I'll be here all week.Quote:

In case he wasn't joking... Bill, most any aviation headset will work with almost any AUDIO source* (whether it's an aviation radio or a stereo/HiFi or a boom box) that has a ¼ inch plug, or can be adapted to such. The question would be more appropriate for RADIOS but, to the best of my knowledge aviation frequencies are pretty much the same around the world (including being AM rather than FM or sideband) else international travel would require multiple radios. The only real incompatibilities I'm aware of are between typical military freqs and typical civilian freqs.
* the ear pieces will pretty much all work -- some microphones aren't as good on non-aviation sources, though.
Good summary, Larry.Quote:

The GA standard is a 1/4" plug for the speakers, and a 0.206" plug for the microphone. The latter stems from the telephone switchboards of the early 20th century, and is currently only used in General Aviation. There are other standards used in aviation... helicopters have their own, single connector, system, there's a NATO plug, etc.
So if one is going to the UK with the intent of renting an aircraft, one will want to know that the jacks on the aircraft will be compatible with the plugs of your headset. I've never seen anything to indicate they use anything but the GA standard. If they didn't, you'd see "UK" versions of the headsets for sale, just like you see "Helicopter" headsets.
The 0.206" plug isn't the only fossil in aviation radiotelephony. The 300-ohm speakers used in GA headsets is another...again, harking back to the days of telephone switchboards. The microphones, too...while all aviation headsets use dynamic or electret mikes, the installations are designed to mimic the carbon mikes of the 1920s.
The Air Force, about 60 years ago, modernized. They now use the standard 8 ohm speakers and modern microphone elements.
Again, though, I believe the GA aircraft in the UK use the classic GA standard.

I wasn't joking, I was considering taking my helmet there for some flying. I expected it to be the same, but wasn;t certain. I think phone chargers and electric razors have different plugs and voltages there, but again Im not sure. I know some of there flying norms or habits are different such as a curving approach from downwind to final rather than a straight base leg at 90*.
If it has the standard two plug of the US headsets, it should work on any GA aircraft. However, if you're going to try go for a flight with something like the Tiger Club, those planes may use something different. For those sorts of situations, I'd expect them to have compatible helmets to borrow. Ditto with any other warbird.Quote:

Look for "travel adaptors"... places like Target, Bloodbath and Beyond, or even largish drug stores should carry them.Quote:

And not just the plug/jack, but also the electrical characteristics (impedance, etc.) were also telephone standards, to the point that I was actually able to take an early electronic telephone headset and easily adapt it to aircraft usage, mostly by changing the plugs.Quote:

Many countries use 240 VAC where the U.S. used 120 VAC, and many countries run that AC power at 50 Hz (cycles per second) vs. 60 Hz in the U.S., so yes, those items are different, but they have nothing to do with what aircraft use.Quote:

So if your helmet has the ¼" audio plug, and the .206 mic plug, it should work fine in their aircraft that are so equipped. But if your helmet has the military style 4-conductor plug (I think it's similar to many helicopters here) then it'll only work in aircraft so equipped.
I'll own up to being a Brit on the forum!
Headsets generally no problem. The radios are mostly Garmin, King ... the same as everywhere else.
The laws of physics are quite similar so not much change in the mechanics of flying.
What you may find different is:
No publicly funded airfields, so you will be expected to pay for the privilege of using them.
You usually enter the circuit (pattern) from the overhead crossing the upwind end of the runway at 90 degrees and turn on to the downwind. No 45 joins.
VFR advisories are called a 'Basic service' and the service is sporadic and a squawk code is limited to one controller. Conspicuity is 7000 not 1200.
Many places will require you to wear a high-visibility vest while air side.
Most small airfields have an air-ground frequency which has an operator who can give information but not instructions. Make calls to the station like you would on CTAF; downwind, finals to land etc which will be replied with roger/traffic info/wind info etc.
Non radio airfields use a system similar to CTAF on 135.480 MHz to be used to self announce when close to the field. Radios are now 8.33 KHz channel spacing (2280 channels).
Airways are class A down to quite low levels, so VFR is generally forced to fly at the lower levels.
It rains a lot and 100LL is expensive.
Thanks, Mark. Are their common British parachute makers or do they mostly use the standard American ones like Strong, Butler, Softie etc.?
There are British parachute manufacturers - IrvinGQ mostly supply the forces, but do sell to individuals too. A few others supply to the skydiving and sailplane communities as well as the aerobatic with seat pack and back pack types. The US ones you mention are also fairly commonly used.Quote:
