Plain English Summary

1/10 complexity

This safety directive requires owners/operators of aircraft fitted with ARC Type 319A or 319G VHF COM/NAV radios to modify the localiser and glide‑slope flag circuits so they draw power from the 90–150 cycle output filters. The change ensures the ILS warning flags are reliably powered so pilots won’t follow faulty landing signals. Compliance via Rex Aviation Radio Design Change No. 6 was required before 1 January 1966.
