Shannon is not meant to have clearance delivery is it? I picked up a shamrock recieving clearance on 121.70mhz. Comments on this?

There was some problem with his flight plan, etc etc... the there was not much read back except cruise level and sqwawk. All other aircraft recieve it on ground (121.80) when taxi-ing out.

I think 121.7 Mhz arrived in Shannon just in time for J.F.Knnedy's visit in 1963 - but was probaly actually used for he first time when Pope John Paul II dropped by in 1979

all aircraft are issued with their clearance during taxi from an aerodrome with atc service so what are you on about as regards this freq.I can only assume what you heard was a flight data controller at the shannon acc issueing aan oceaninc departure with his oceanic clearance or perhaps it was a transiting oceanic flight recieving his oceanic clearance from Shanwick

You are correct in that Shannon does not have a dedicated clearance delivery frequency. Clearances are normally delivered on the ground frequency of 121.8.
However, aircraft departing Shannon on an oceanic route are required to contact Shannon ACC either by VHF 121.7 or telephone 45 minutes prior to departure in order to obtain their oceanic clearance.
I suspect in most cases this clearance would be obtained by the operator or handling agent by telephone. Otherwise the pilot will use the published frequency of 121.7 to obtain a clearance or to query an already received clearance. The pilot will then receive a domestic clearance (from Shannon to the oceanic entry point) on 121.8 as per usual.
If your can get your hands on an AIP you may read more about this on ENR 2-19.
Hope this explains it for you.

No it was not Shanwick! There was some problem with the flight plan as there was another a/c crossing the atlantic at the same time and he could either have a delay or cross at a lower speed.

Yea apparently only one aircraft is allowed over the atlantic at a time!
Sorry I could'nt resist.
