Safety Altitude
Safety Altitude is that which will keep you not less than 1000 feet above terrain five miles either side of track or ahead of you.
The SA for the leg Mull-Corran was 5900' because of higher ground near Corran.
The SA at the Mull was 2400 feet because that would have kept the aircraft 1000 feet above the highest point on the Mull and there was no higher ground less than five miles ahead.
You would need to consult the map to see when 2400 feet would no longer have been applicable, ie, because of higher terrain.
First sentence should read, "Safety Altitude 'in IMC',"
