CAP 413 and AIP Confusion.

Dear ATC

Please can you clarify some R/T confusion for me? (I have done a search and am not sure which thread to attach this to).

CAP 413 says that after making initial contact with an ATSU I should give certain bits of information. Why do I have to tell you Departure point and destination? Please don’t say it’s because you can send the search parties out if I don’t arrive, because you can never know which private site I am going to/from:

Also I may want to deviate from track to fly over some places that are not between departure point and destination, so you won’t know which bit of airspace I am in unless I stick it onto the end of the transmission, thus lengthening the exchange and clogging up the frequency.

Do you really want all of this info? I think it might be a bit unrealistic for helicopters. Here is an example of a made up long distance flight. “G-XXXXPass your message”

Helicopter G-XXXX,
R44
Private site 5 miles north of Town X to Private site 8 miles south west of Town Y (at the other end of the country)
Overhead Town Z
1001ft QNH 1013
Request FIS (routing via a castle, then someone’s house in the middle of nowhere etc………)

Also CAP 413 contradicts information in AIP’s AIC’s e.g. MATZ penetration:

The Gospel according to CAP 413
Callsign
Type
Departure Point and destination
Present position
Level
Additional Details (e.g. flight rules, next route point, favourite colour, dogs name etc…..)

The Gospel according to AIPENR
Callsign
Type
Position
Hdg
Level
Intentions (e.g. Destination).

So my question is what information do you really want to hear from pilots in response to "Pass your message". Please give answers to each different request e.g. Zone transit, MATZ penetration, Request FIS, RIS, joining, contacting LARS, position report etc etc.....I know you want concise, useful information and not a load of longwinded irrelevant stuff.

And what’s the deal with AFIS and A/G stations? Us Telling them the frequency that you we calling them on, and then having to do a readability check. If you are on the wrong frequency, they can’t hear you, and if your readability is less than 5, someone will tell you anyway. (It's like phoning people up and then telling them what their telephone number is)

Many thanks for your help, I am genuinely confused . And apologies for the longwinded post.

P.S And thank you all for the professional service that you provide. You are all top quality. It’s a shame we can’t always meet the people behind the voice. Keep up the good work.

Best regards
