Every time I fly in a non-radar environment I prefer to set an offset to the right of the airway.
Just had an argument in the cockpit about it. The other guy believes that it is "to look for trouble" to set up even a quarter mile offset in non-radar environment flying over the East Africa's best: Tanzania, Kenya, Somalia, Yemen.
Surely you jest. Has the other guy seen how close aircraft are when they cross, opposite direction, on the same airway? The Australian AIP officially allows offsetting in oceanic controlled airspace (probably similar to non-radar African airspace?) by 1 or 2nm and recommends it when operating at non-standard levels.
