My advice would be to suggest that if FISO and LARS and ATC units were really connected rather than just by having a telephone call the whole situation would be better. In this day and age of Global Intergrated Communications any non flyer would be amazed that air safety is often based on people just making a telephone call.
I use Farnborough anf Brize alot and get excellent service but feel sometimes that asking for a co-ordinated approach in to say Blackbush from Farnborough is too much of an ask. They have to go off line to make a phone call. What I then have to do having negotiated round 2 MATZ is an overhead join at 250 IAS slwing to 160 in the circuit which for passengers is a fairground ride. I also use FISO when I get dumped out of the airways a long way from my destination which is often the case in the South East. A FISO service at 300knts is helpful but in IMC dangerous then I have to try and get de-conflict from someone.
A more published procedure would be very helpful for pilots who are tryning to do the right thing. I think this would be a constructive approach to your new emplyees. They will believe that IFR and airways have little to do with FISO as they only think of the large airports and published Instrument Arrival and Approach.
