Was flying EDI-BLL the other day, talking to Scottish, when they lost contact with Delta 69. After numerous attempts to contact them on the frequency and also 121.5, no contact was made.
We were asked to try and relay to Delta 69 on Copenhagen's frequency, once Copenhagen gave permission.
Eventually, we made contact and gave Delta 69 the correct frequency.
My question is.......
What is the process to go through to try and establish any communication - i.e. squawking ident if the a/c can receive transmissions, trying the a/c on guard or on neighbouring sectors' frequency, and ultimately, when would you ask for the a/c to be intercepted?
I realise this may be sensitive information and I wish I had asked it in a recent visit to EDI tower but alas. I would happily take a PM if it helps
Thanks
