In case it's of any help to any of the contributors to this post, the DSA MSA's to the East of the airfield are based on the following:
- Northeast of FNY 1900' (referred to by PBY in the original post) is based on Drax power station which is 14NM North of FNY, maximum obstacle height 873ft AMSL; and
- Southeast of FNY 1700', based on another power station 8NM East of FNY at Gainsborough, maximum obstacle height 686ft AMSL.
The ROGAG 02 Planned Departure Route, as described by Bookworm, requires the departing aircraft to follow the GAM Radial 017 inbound to the Gamston VOR until 5NM north of Gamston, thereby almost 10NM South of the Southerly-most significant obstacle, or FL80 - over 7000ft above said obstacle;
whichever the later!
Note: Should anyone wish to investigate where the GAM R017 runs in relation to any of the above, they will find that directly East of the FNY it lies at a distance of approximately 4.5NM from the NDB, thereby providing more than adequate separation from any of the significant obstacles in the area.
As PPrune Radar has already pointed out, the procedure cannot legally be described as a Standard Instrument Departure because containment in Controlled Airspace cannot be guaranteed for
all aircraft flying that particular route; however, any pilot using EGCN may rest assured that the procedure is most definitely safe and has been carefully designed to make sure that you or your aircraft do not make any unwanted acquaintances whilst flying it!
So, less of the scaremongering please.
