SLOP (Strategic Lateral Offset Procedure)
Every time I fly in a non-radar environment I prefer to set an offset to the right of the airway. Sometimes even in “radar” environment (in some countries) I opt for R0.1.
Just had an argument in the cockpit about it. The other guy believes that it is "to look for trouble" to set even a quarter mile offset in non-radar environment flying over the East Africa's best: Tanzania, Kenya, Somalia, Yemen.
