SID's for the Ice Station have been looked at a number of times and there are a number of drawbacks....
Majority of Traffic departs into Class F (Advisory) or Class G (uncontrolled) Airspace. Having SID's into such airspace is probably not a good idea with all those very fast swing-wing things zipping about.
There is a paucity of ground based Nav aids to construct the SID's from.
A SID for P600 departures would in all probablity have to terminate at a Flight Level rather than an Altitude because of the Base Level of the Airway.
SID's would mean STAR's as well and on 16 inbounds from the South would have to stay up at FL90 or FL80 til at least abeam the Airport (and on 34 inbounds from the North would also suffer) thereby extending the approach track distance considerably and also putting an end to the short visual approach!
As anyone who operates in/out of Aberdeen has probably noticed, the traffic has a remarkable tendency to "direction bunch" - 4 or 5 all going the same way at the same time. To get them all airborne in the minimum time we would still have to use Radar Headings to provide seperation - as now - kind of makes the SID superfluous! Alternative is to have Departure Tables (time based seperation) which would mean you sit on the ground for much longer waiting for the one ahead to get far enough away.
So, IMHO, the present system works well for the traffic type and flows we get, is very flexible and leads to minimum delays (usually!) for both inbounds and outbounds. It may be different from a lot of Airports today but there have been recommendations to "improve" the "user friendliness" of the system for aircrew - No 1, dust off the APRG report and look at SDR's
And as BA flight plans have already been mentioned..... if any BA crew read this - please telll your ops dept that the daily flight plans they file are a) often wrong - departing off of 34 you do NOT go to the AQ! and b) are so long winded that our printed Strips do not show the correct Flight Planned Level!
