ON - Valve is open, supplying low pressure oxy. - is normal position in flight OFF - Valve closed. White light on. A340 - Pneumatic latching system allows masks to fall when cab alt exceeds 14,000ft (+0, - 500ft). Altimetric flow regulation device controls passenger flow rate from oxy cylinders located behind RH sidewall lining in FWD cargo compartment. A330 - Electric latching system allows masks to fall when cab alt exceeds 14,000ft (+0, -500ft). Oxy delivered at constant pressure by oxygen generator which last about 22 min. Oxy generation may emit heat and smoke. PASSENGER SYS ON White light when system on. Remains on until RESET on maint panel is pressed. MASKS MAN ON PA automatically broadcasts instruction whether MAN or AUTO deployment AUTO - Normally in AUTO position. Masks auto drop at 14,000ft cab alt. Pressed - Masks drop RESET (A340) Maintenance crew use this pb to reset after the system has operated. ON - White light comes on, PASS SYS ON light goes off, PA recording stops. - System shut off valves close - Main supply line shut off valves open - ON light goes off when reset complete (3 sec) FAULT Lt – Amber when reset failed. RESET (A330) Maintenance crew use this pb to reset after the system has operated. ON - White light comes on, PASS SYS ON light goes off FAULT Lt - Amber when door latch solenoids are energized for more than 30 secs Overhead Panel Switches 01-Aug-10 For reference only 29 AUTO CLOSE OPEN 36. PNEUMATIC ENG 1 BLEED (2,3,4) ON - Bleed valve opens provided: - Upstream pressure is >8psi - APU BLEED pb is at OFF or APU bleed valve closed - No onside wing or pylon leak, overpressure or overtemp. - ENG FIRE pb is not released - Eng start valve closed FAULT Lt - Amber with ECAM if: - Bleed valve not closed during eng start - Bleed valve not closed with APU bleed ON (and for RH eng X-bleed open) Also with auto closure of bleed and HP valves - Overpressure downstream of bleed valve - Bleed overheat - Wing or eng leak on related side - Extinguishes when ENG BLEED pb is at OFF provided failure disappeared OFF - Bleed and HP valve close. - OFF light white - FAULT Lt & autoclosure signal reset APU BLEED ON - APU bleed valve opens provided: - N > 95% - Altitude < 25,000ft climbing or < 23,000ft descending - No leak detected on APU or LH bleed (leak RHS X-bleed would close) ON light Blue OFF - APU bleed valve closes FAULT Lt - Amber with ECAM if APU leak detected X-BLEED AUTO - X-bleed valve is open if APU valve open - X-bleed valve closed if APU valve closed OPEN - X-bleed valve is open CLOSE- X-bleed valve is closed Overhead Panel Switches 01-Aug-10 For reference only 30 49. APU MASTER SW ON/R - Blue light - Elec pwr supplied to APU system, ECB performs pwr up test - APU air intake flap opens - APU fuel isolation valve and APU LP valve open - Fuel pumps operate (FWD & AFT) - APU page appears on ECAM OFF - Manual shutdown sequence: - ON light goes off - APU keeps running for 105 sec at 100% for cooling - After further 15 sec (NBPT) APU shuts down and AVAIL Lt goes off - AT N 7% air inlet flap closes Note: Switching OFF then ON the MASTER SW resets the ECB FAULT Lt - Amber with ECAM when automatic APU shutdown occurs, due to : - Fire (on grnd only) - Reserve flow - Air inlet flap not open - Low oil pressure - Overspeed - High oil temp - No acceleration - DC power loss (BAT OFF when a/c on batt only) - Slow start - ECB failure - EGT overtemp - No flame - Loss of overspeed protection - Underspeed START ON - Blue light comes on. - When flap is fully open APU starter is energized - N = 7% , ignition turned on - N = 50%, APU starter de-energized - N = 95%, ignition turned off ON light on START pb goes out AVAIL Lt comes on - APU may now supply bleed air and elec pwr to a/c. 10 sec later the APU page on ECAM disappears AVAIL Lt - Green when N reaches 95% Overhead Panel Switches 01-Aug-10 For reference only 31 70. POWER PLANT A340 & 330 ENG MAN START (1,2,3,4) ON - Start valve opens if ENG START sel is CRANK or IGN/START - both pack valves close during start - start valve closes automatically when N2 ≥ 50% (N3 ≥ 50%) - On light Blue OFF - When ENG MAN START pb is set OFF during manual start, start valve closes provided eng master switch is OFF ENG FADEC GND PWR (1,2,3,4) FADEC has 2 channels (1 active & 1 in stby). Also an internal magnetic alternator power source supplies FADEC >8% N3 ON - FADEC supplied for 5 min (except if ENG FIRE pb is released out or FADEC generator is avail). N1 MODE 1 A330 ONLY ON - Thrust control reverts from EPR mode to N1 rated mode. - Following an automatic reversion to N1, rated or unrated mode, pressing the pb confirms the mode. - ON light Blue. OFF - The FADEC controls the eng in EPR mode if available. Note: If in N1 mode: No auto thrust, ALPHA FLOOR prot lost & FLEX T/O lost. Rated N1 mode - FADEC computes an EPR COMMAND depending on TLA, then convert it into a N1 COMMAND as a function of mach Unrated N1 mode - N1 is defined as a function of TLA and altitude and is limited by FADEC to smaller of N1 max or N1 Redline (if eng data T2, total air temperature, is avail) or N1 Redline (if T2 not avail)
