Explanation of Changes

Effective: July 9, 2026

a. 4-7-4. AUTHORITY FOR OPERATONS WITH A SINGLE LONG-RANGE NAVIGATION SYSTEM

This change updates all references from the B054 authorization to be replaced with B036 authorization.

5-4-5. INSTRUMENT APPROACH PROCEDURE (IAP) CHARTS

This change updates AIM paragraph 5-4-5 to clarify that PPR requirements may also apply to civil airports, not just military locations, based on NOTAM publication.

This change adds the recommended practice of preloading intended GPS waypoints into the GPS receiver while the aircraft is on the ground.

This change updates language, stating the new forecast valid time and changes the outlook valid time period in the example to 1 hour.
