Lessons Learned

✈RNAV implementation in some regions over past 15 years has highlighted some issues.

✈The following slides list a few of those issues.

30

RNAV 5 implementation en-route airspace

✈ Selecting the right Nav Spec can be a challenge… sometimes there are more older aircraft than expected

✈ Roll out airspace changes over time: avoid multiple airspace changes at the same time as the PBN switch on date

✈ ‘Switch on’ PBN in the Terminal Airspace should be matched by ‘switch on’ in continental en route…

31

RNAV 1 and 2 implementation

✈Aircraft populations may not make ‘cleaner’ turns because of PBN … watch turn angles in design

✈ Co-ordination with stakeholders is a pre-requisite for success

✈ The number of SIDs/STARs at some major airports increased significantly which caused problems for operators with limited data base storage space.

✈ Education needed on RNAV and RNP
