comm failure

[westinghouse]

hi guys and girls,

suppose you were to get airborne from london heathrow to a far away destination and you experience comm failure.
othe than setting the squawk 7600 etc.. what would you controllers expect us pilots to do.

continue to our far away destination
if in VMC perform a visual circuit and land looking out for the light signals.
if in IMC head towards lambourne, join the hold and commence the approach.thank you very much.

If you think it's bad enough to justify a return to the departure airport, squawk 7700 would be recommended. How you get onto the approach is a different story, and I recommend having a look at the AIP.

If you think it's not as bad as to prevent you from continuing your flight, you squawk 7600 and follow the standard procedures (as they should also be detailed in the AIP). That means you follow the routing (if you had a shortcut issued, continue on the direct and join the routing there; if you were on a vector, join the routing as soon as practical), maintain your last cleared altitude for a defined lapse of time (7 minutes in Austria, should be the same about everywhere) and then climb straight through to cruise level. The 7 minutes start to run at the time you squawk 7600 or reach the last assigned altitude, whichever later.

I would expect anything. 7600 or 7700 and a return at sometime.
Are you dumping fuel etc? Keep all other aircraft out of your way.
