Interpretation

The AIRAC 12/2026 changes scheduled for 26 November 2026 to remove DME MAC and introduce DME CAL have been cancelled. From that date, remove the DME CAL reference and reinstate DME MAC in the UK AIP and digital dataset. DME MAC operates H24 on channel 107X/116.000 MHz; it has no associated en-route VOR, and terrain reduces low-level coverage in specified sectors.
