- I'm not sure where 'RNAV overlays' have got to since I quit flying, but it used to be a requirement to monitor track keeping using 'conventional' aids AND not to use the 'turn anticipation' built into RNAV ie where you route via an NDB the RNAV should take you OVER that beacon and not turn early for the new course. Thus in the BUZAD shown you would be required to pass over the D10 before turning onto the BIG 331 whereas the kit might 'anticipate' that turn. Folk like ATERPSTER or OBN will be able to update here - it may have changed. Certainly the last 733's I flew were NOT allowed to fly 'RNAV' SIDs or STARs and I recall always asking in ?Oslo? for vectors since they only had RNAV SIDs (and the vectors always reduced the mileage.
