Offset
It’s a little bit off topic:
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.
It is always good to add a layer of a Swiss cheese if you can.
