Hi Topunicyclist.
The basic answer is no, I'm afraid it's a non starter unless it's a winter Saturday and you just hit the right time to transit. I'll try and keep this simple to show you what the MAN APP and TWR guy do so you can see what goes on behind the scenes when we accomodate such a request. To make this work you need to remember that the TWR man can see the outbounds taxying but the APP man is down in the 'dark'.......
You make your request, lets assume you want 1500ft QNH or more...APP phone tower and check (stop), all Listo departures.....This isn't a problem until you pass Jodrell Bank. Lets say that at this point the tower ring APP and say they have one..O.K. APP then issue a non standard IFR clearance to the outbound and then ring the appropriate AREA sector to tell them what to expect....The ATSA logs the IFR non standard clearance to avoid MIA fining the outbound for a noise violation.....If there is any IFR departure on any routeing behind the Listo it picks up a knock on delay which can vary between 1 and 4 minutes depending on aircraft type............As you get near Knutsford APP phones TWR to give 'tracks clear' Listo departures, and check (stop) Nokin/Monty/Wallasey departures....at this point, if there are any departures then read again the bit above that starts..'Lets say at this point...' ...As you leave the zone into the low-level route we give tracks clear and back to normal ops...Pheeew!!!
Variations to this can involve APP identifiying you to TWR and TWR applying the non-standard clearance to the outbound IFR traffic, if neccessary, but co-ordination remains the same. The complication comes because the standard ATC system is designed to give the TWR a 'free fire zone' for departures and you would be requesting transit through this zone. There are certain areas we can let you go through under certain operational circumstances and we'll do our best to offer a short cut if possible but the best thing is to plan for the Low-level route. I'm bound to have forgotten something cos I've got a streaming cold at the moment and feel c**p! Thought I'd chip in with something as the usual Manchester posters didn't seem to be forthcoming.
