OK I only do the "inter european" routes.

Occasionally when flying from northern Europe to the Canaries, we use T9 and T16. Here we do not use plotting, even though there is more than 725 nm between navaids (ref extract from AC91-70A below)

Is that wrong ??



3-6.
POSITION PLOTTING.
a.
Plotting and Systematic Cross-Checking of Navigation Information. During all phases of flight in Class II navigation, each operator’s long-range navigation program (LRNP) will require the standardized application of disciplined, systematic cross-checking of navigation information.
(1)
Plotting Procedures Impact. Plotting procedures have had a significant impact on the reduction of gross navigation errors (GNE). There is a requirement to plot the route of flight on a plotting chart and to plot the computer position approximately 10 minutes after waypoint passage. This may or may not require plotting, depending upon the distance between the standard ICAO ground-based NAVAIDs. This applies to all operators.
(2)
Turbojet Operations. All turbojet operations, where the route segment between the operational service volume of ICAO standard ground-based NAVAIDs exceeds 725 NM, require plotting procedures.
