News from 12 June 2018. Last updated on 13 June 2018: some information may have changed. Latest news

Here is a short explanatory note from the FFPLUM Airspace Committee on the radio communication conversion plan to 8.33 MHz, particularly in relation to class E and G airspace.

The roll-out of the conversion plan to the 8.33 radio communication standard is under way and the time we have left is short.
Extract from the DGAC conversion plan:
PHASE 1: 2th half-year 2018 & 1st half-year 2019
- conversion to 8.33 kHz spacing of all frequency assignments for the management of controlled airspace of class A-C-D
From 01/01/2021:
- all aircraft (other than State aircraft) must be equipped with 8.33 kHz radios, whatever their category, type of flight (IFR / VFR) and the class of airspace they use.
Derogations notified to the European Commission:
- Radios of aircraft flying VFR are exempt from the 8,33 kHz capability in class D airspace until 31 August 2018;
- Radios of aircraft flying VFR are exempt from the 8,33 kHz capability in class E and G airspace until 31 December 2020.
EU Implementing Regulation No 1079/2012
https://eur-lex.europa.eu/legal-content/FR/TXT/?uri=CELEX%3A32012R1079
| To keep it simple: • 1 September 2018: class A-C-D airspace, 8,33 radio COMPULSORY • 1 January 2021: class E–G airspace, any aircraft fitted with a radio MUST be on 8.33 |
Warning: the frequency 123,50 (25 kHz) used for self-announcement at many airfields can no longer be used; it will be replaced by 123,500 (on 8.33)
Any pilot using a radio other than 8.33 will cause interference that can jam communications and thus endanger flight safety.
Vigilance and unity are more necessary than ever. The FFPLUM airspace committee thanks you for this.
