ObjectifObjective
Savoir quand allumer SERV INT ON, où est le Fueling Station (R wing LE), et pourquoi le switch doit être OFF en vol.Know when to set SERV INT ON, where the Fueling Station is (R wing LE), and why the switch must be OFF in flight.
FLIGHT INTERPHONE
- Circuit fermé Capt / F/O / OBS. Accès sol via jack au External Power Panel.Closed circuit Capt / F/O / OBS. Ground access via jack at the External Power Panel.
- Labels ASP (as installed) : INT · FLT · FLT INT. Rangée typique : SERV INT | FLT INT | PA (mic select + volumes).ASP labels (as installed): INT · FLT · FLT INT. Typical row: SERV INT | FLT INT | PA (mic select + volumes).
- Canal actif = barres mic jaunes + base de volume allumée.Active channel = yellow mic bars + lit volume knob base.

| Flight deck ↔ flight deckFlight deck ↔ flight deck | NOGO — requis pour interphone masque O₂required for oxygen-mask interphone |
SPEAKER MUTE · PTT (IN FLT)
- Un ou les deux speakers overhead mutent quand PTT tenu en INT ou MIC — sauf mic masque O₂ (speakers restent live).One or both overhead speakers mute when PTT held in INT or MIC — except oxygen-mask mic (speakers stay live).
- Cruise speakers : couper Flight Interphone. Certains PTT peuvent rester lockés INT → rater ATC.Cruise speakers: turn Flight Interphone off. Some aircraft PTT can lock in INT → miss ATC.
- Après retrait casques → presser VHF TEST (squelch) pour confirmer volume speakers audible.After removing headsets → press VHF TEST (squelch) to confirm speaker volume is audible.
Trap quotidien : casques off / speakers on — quand l’autre pilote PA ou TX sur une autre radio, speakers inhibés → rater ATC sur VHF-1. Préférer casques.Daily trap: headsets off / speakers on — when the other pilot PAs or TXes on another radio, speakers inhibited → miss ATC on VHF-1. Prefer headsets.
SERVICE INTERPHONE · SERV INT ON
- Circuit fermé : flight deck + fwd galley + aft galley.Closed circuit: flight deck + fwd galley + aft galley.
- Service Interphone Switch (Aft Overhead) ON ajoute 7 stations extérieures — utilisé pour certains non-normaux (ex. manual start valve).Service Interphone Switch (Aft Overhead) ON adds 7 exterior stations — used for some non-normals (e.g. manual start valve).
- Pour parler au sol : switch ON + ASP CABIN / SVC / SERV INT · prévenir la cabine de ne pas interférer.To talk to ground: switch ON + ASP CABIN / SVC / SERV INT · advise cabin not to interfere.
In FLT Switch OFF — évite arcs sur jacks extérieurs (dommage peinture / bruit réseau).In FLT Switch OFF — prevents arcing on exterior jack plugs (paint damage / network noise).
Malfunctions deck↔cabin / cabin↔cabin au sol → MEL 23-04 (b) [Crewmember Interphone System].On GND deck↔cabin / cabin↔cabin malfunctions → MEL 23-04 (b) [Crewmember Interphone System].
