TP 14371E Transport Canada Aeronautical Information Manual (TC AIM) RAC—RULES OF THE AIR AND AIR TRAFFIC SERVICES MARCH 26, 2020 TC AIM March 26, 2020 TRANSPORT CANADA AERONAUTICAL INFORMATION MANUAL (TC AIM) EXPLANATION OF CHANGES EFFECTIVE—MARCH 26, 2020 NOTES: 1. Editorial and format changes were made throughout the TC AIM where necessary and those that were deemed insignificant in nature were not included in the “Explanation of Changes”. 2. Effective March 31, 2016, licence differences with ICAO Annex 1 standards and recommended practices, previously located in LRA 1.8 of the TC AIM, have been removed and can now be found in AIP Canada (ICAO) GEN 1.7. RAC (1) RAC 1.1.2.1 Flight Information Centres (FICs) In (b) FISE, fireball reporting procedures were removed. The reporting of fireball occurrences is no longer required by the government or military. (2) RAC 1.1.2.2 Flight Service Stations (FSSs) (a) AAS As NAV CANADA moves ahead with runway determination at FSSs with direct wind reading instruments, the phraseology will be changing from “preferred runway” to “runway”. (3) RAC 9.2.1 Minimum Sector Altitude (MSA) A note was added regarding the flight validation of MSA. (4) RAC 9.6.2 Visual Approach Additional text was added to clarify information about ATC visual approach clearance and missed approach procedures for aircraft on an IFR flight plan. (5) RAC 9.17.1 Corrections for Temperature Information was added to clarify some temperature correction procedures. (6) RAC 9.17.2 Remote Altimeter Setting The information was updated to specify the instrument approach procedure segments to which the RASS adjustments are applied. (7) RAC 9.23 Circling Two new sections were added, including new textual information and tables on new expanded circling approach radii. (8) RAC 11.5.1 Northern Control Area (NCA) Track System This subsection was deleted since NAV CANADA is removing the last references to NCA tracks from publications.
