According to the FAA, “We are delaying aircraft compliance with the AC, but still expect operators to comply with the operational guidance contained in the AC. Since HOST computers systems have been modified (along with other flight planning software systems), there really is no easy way to go back to ‘todays’ process tomorrow.” The issued NOTAM is as follows:
!FDC 5/7641 (KFDC A0058/05) FDC THE IMPLEMENTATION DATE FOR AIRCRAFT COMPLIANCE WITH AC 90-100 HAS BEEN DELAYED UNTIL SEPTEMBER 29, 2005. IN THE INTERIM, ALL OPERATORS THAT COMPLY WITH THE REVISED AIRCRAFT EQUIPMENT SUFFIXES /E, /G/, /R, /J, /L, AND /Q ARE AUTHORIZED TO FILE AND FLY RNAV SIDS/STARS AND ROUTES. OPERATORS SHOULD COMPLY WITH THE OPERATIONAL GUIDANCE CONTAINED IN AC 90-100.
