Good topic slippers - thing is the radio never seems to fail at nice moments like entering a hold. Last time my precious 'bus did it to me I was on vectors at CDG preparing to take a heading to intercept the loc. Those familiar with the crl 120r will kno wthat your last heading before amn intercept takes you towards incoming traffic from the East. We finally got it working in time, and in post flight decided that we probably have just gone 7600 and intercepted & taken the b****ing on the ground.
Seemed to us that would have been safer than continuing towards 5 or 6 inbounds or climbing up and out of it. Not sure it would be ideal though.
