ACTION

Action : retirer la fiche du microphone coincé de son connecteur.Action: remove the stuck microphone plug from its connector.
Certains installs : toute station TX inhibe temporairement tous les overhead speakers → si micro coincé non retirable, utiliser casques.Some installs: any station TX temporarily inhibits all overhead speakers → if stuck mic cannot be removed, use headsets.

Trap quotidien : casques off / speakers on — quand un pilote PA ou TX sur une autre radio (ex. VHF-2), speakers overhead inhibés → rater ATC sur VHF-1. Préférer casques quand l’autre TX/PA.Daily trap: headsets off / speakers on — when one pilot PAs or TXes on another radio (e.g. VHF-2), overhead speakers inhibited → miss ATC on VHF-1. Prefer headsets when the other TX/PA.

Retirer fiche d’abord. Sinon casques (speakers inhibés).Unplug first. Else headsets (speakers inhibited).

HF COUPLER NOTE

Honeywell HF couplers (certains) : ton de tune continu en altitude / basse pression cabine — quirk design ; disparaît au sol. ≠ stuck mic.Some Honeywell HF couplers: continuous tune tone at altitude / low cabin pressure — design quirk; clears on ground. ≠ stuck mic.
