FUEL PANEL - L/R XFLOW Switchlights (With AUTO OVERRIDE Switchlight pressed out, automatic mode) ON light illuminates to indicate the respective SOV is open and the crossflow/APU pump is on. FAIL light illuminates to indicate the respective crossflow SOV is not in the commanded position or the crossflow/APU pump fails to go on with the left or right
FUEL PANEL - AUTO OVERRIDE Switchlight Pressed in – XFLOW/APU pump is armed for manual crossflow, automatic crossflow is disabled. MANUAL light goes on. Pressed out – XFLOW/APU pump is disarmed for manual crossflow, automatic crossflow is enabled. MANUAL light goes out.
APU PANEL - PWR FUEL switchlight Used to control APU fuel pump. When pressed in, crossflow/APU pump is energized, APU IN BITE, APU gauges energized, door scheduled to open, and APU fuel shut-off valve opens. PUMP FAIL (amber) light indicates that APU fuel pump has failed. SOV FAIL (amber
APU PANEL - START/STOP switchlight When pressed in, starter motor is energized and START light (white) illuminates. At 50% rpm, START light extinguishes. At 95% rpm, and 4 seconds later, AVAIL light (green) illuminates. When pressed out FCU shut-off valve closes, APU shuts down, and AVAIL
ENG INGNITION PANEL - L/R START switchlights Used to initiate engine start sequence. START (white) light indicates start is selected.
ENG INGNITION PANEL - L/R STOP switchlights Used to stop engine start sequence. STOP (white) light indicates stop is selected.
ENG INGNITION PANEL - IGNITION A and B ARM (green) – Arms respective ignition system on both engines. ON (white) – Indicates the ignition system is activated.
ENG INGNITION PANEL - CONT Used to select continuous ignition of both ignitors on both engines. ON (white) light indicates continuous ignition is selected on.
ENG INGNITION PANEL When is ignition A used and when is B used? What are their power sources? When is starter cutout? Ignition A on odd days, ignition B on even days. Ignition A is AC powered, ignition B is DC powered through a static inverter (can start on battery only, no AC power required). Starter cuts out at 55%
FUEL PANEL - XFLOW FAIL valve is not in commanded position
FUEL PANEL - BOOST PUMP INOP Boost pump not on. Low pressure. Boost pump failed
FUEL PANEL - When is auto fuel transfer At 200# imbalance, fills to +50#
FUEL PANEL - When is fuel transfered from center tank to main tanks? When main tanks reach 94% (4474#ea,8984#total) fuel is transferred from center tank to main tanks until mains reach 97% (4617#ea, 9234# total)
FUEL PANEL - How does the fuel flow from center tank to engine? 1. From center tank to main tanks via transfer ejectors 2. From main tanks to collector tanks (always full, hold 10gals) via scavenger ejectors 3. From collector tanks to engines via main ejectors. Ejectors assist w/motive flow
HYDRAULIC PANEL (3 systems) System #3 Largest reservoir, Serviced and located in right main wheel well, Cooled via a fuel heat exchanger in right wing (L wing contains bulk fuel temperature probes)
HYDRAULIC PANEL Systems #1 and #2 Located and service in aft equipment bay. Cooled by RAM air in flight thru RAM air inlet. Cooled by fans on ground thru RAM air inlet
HYDRAULIC PANEL Describe Pumps 2 Engine driven pumps (1A,2A), 4 AC Motor Pumps (1B,2B,3A,3B), 3A always on, 3B also powered by ADG, all pumps are on when flaps are out of 0 (critical phase of flight)
HYDRAULIC PANEL Which pumps are lost during engine failure? Lost left engine, lose 1A & 2B. Lost Right engine, lose 2A & 1B
HYDRAULIC PANEL Normal ops quantity and pressure: 45-85% system quantity, 1800-3200 PSI
