We are still in the process of working with AJV-14 and AFS-400 regarding the "Lateral
Protected Airspace Criteria for RNAV ATS Routes", which we hope will lead to change in
criteria and reduction in the basic width of an RNAV route.
Pilot Controller Procedures & Systems Integration (PCPSI)
A meeting was held in Henderson, Nev. on Nov. 8th-10th. I was unable to attend as I
was in Montreal for the ICAO PBN STUDY WG, but Andy Marsovari, NATCA
Procedures Rep was in attendance. Items discussed or presented were as follows:
Speed Guidance - Pilots have been confused with a "Descend Via" clearance after a
previously assigned speed as by definition a "Descend Via" clearance cancels any
previous instruction and all altitude and speed constraints on the procedure are
mandatory. During the discussions, the team learned the Airmen Information Manual
(AIM) did not contain the proper language or examples as those within the FAA 7110.65.
Proposed language was suggested and agreed upon and will be implemented into the
AIM on April 27, 2017.
ICAO – Adopted Climb/Descend Via on Nov. 10, 2016, which is slightly different from
the FAA and Canada will implement on March 2, 2017.
