Preflight and Power-Up
From a cold and dark cockpit to a powered aircraft with the INS aligning. Run the three console checklists while the INS aligns.
COCKPIT PREFLIGHT
Cold and dark on a parking spot (canopy open, every switch OFF), before any power is on.
Note: Short of time? EFB Aircraft tab, Set up aircraft, Ready to start does everything up to the ENGINE START checklist for you: ground power, avionics, INS aligned, switches set (parked, up to 3 minutes, engine off, canopy open). Ready for takeoff also starts the engine. → Electronic Flight Bag (EFB)
EFB
1 AVIONICS STARTUP TIME - FAST OR REALISTIC EFB Settings tab. Fast (default): AVP 7 s, SFD 10 s, EW self-test 30 s. Realistic: 2 min, 3 min, 5 min → Electronic Flight Bag (EFB)
2 INS ALIGNMENT TIME - FULL, SHORT OR INSTANT EFB Settings tab. Full 22 min, Short 3 min, Instant 5 s; you still start and accept the alignment → Inertial Navigation System (INS)
3 SERVICING - CHECK Fuel in the MSFS Fuel and Payload window, at least 70 gal in the sump tank (the engine feeds only from it); LOX on the EFB Ground tab: with the engine stopped, Connect and fill brings the oxygen cart and fills both converters, about 3 minutes from empty to full → Fuel System
4 MISSION EQUIPMENT - SET EFB Aircraft tab - nose, Q-bay, superpods, SPAN, external sensors. ASARS-2 nose = RDR page; SYERS-2A nose, or Standard nose with the Q-bay OBC = CAM page
5 CHARTS AND SUNSHADE - SET EFB Charts tab, or drag the sunshade along the canopy arch
COCKPIT
6 PARKING BRAKE - SET In Parking brake handle mode, pull the T-handle at the lower right of the main panel until the tooltip reads SET. In Stall strip handle mode, secure the aircraft with wheel chocks on the EFB Ground tab or in the walkaround.
7 COMM SELECT PANEL - SET Lower left of the main panel: TRANSMITTER SELECT COMM 1 (HF, D/L and SSR transmit nothing), HOT MIC / CALL RCD OFF, COMM CONTROL NORMAL, MASTER VOLUME off the stop → Up-Front Control Display (UFCD)
Caution: MASTER VOLUME at the bottom stop mutes all headset audio, the warning and caution tones included.
8 UFCD/SFD LIGHTS, INSTRUMENTS LIGHTS, PANEL LIGHTS - SET Three knobs in the centre of the main panel. The panel lights need essential AC (ground power or a generator), the instrument lights emergency AC and the UFCD / SFD lights emergency DC.
9 FUEL BOOST PUMP PRIMARY AND SECONDARY - OFF Fuel panel, right of centre on the main panel → Fuel System
10 INBD AND OUTBD SUMP TANK - OFF
11 INBD AND OUTBD XFER - OFF Cross-transfer switches (their tooltips say XFMR)
12 LEFT AND RIGHT INBD / OUTBD DUMP - CLOSED
13 EW CONT - OFF Top right of the main panel, beside the SFD
14 UFCD, AVP, SFD, BCDU, INS, IFF - OFF Right console power switches (IFF behind them)
15 AFCS POWER - OFF AFCS panel, right console
16 PITOT HEAT - OFF Right console, aft
POWER-UP AND ALIGNMENT
After the cockpit preflight. Start the slow units first, then do the console checks while the INS aligns.
ELECTRICAL
1 BATTERY - EXT PWR Electrical panel, right end of the main panel. EXT PWR / OFF / NORM → Electrical and Avionics Power
2 MAIN DC GENERATOR AND TRANSFORMER RECTIFIER - OFF Their cold-and-dark position; they go to NORM after engine start
3 EXTERNAL POWER - ON One switch for external AC and DC. Connect the cart first: EFB Ground tab, Servicing, Ground power - Connect, and wait for Connected (parked off the runway, parking brake set; Connect brings the ground power unit out if it is hidden). MSFS ground-service power is not used.
Note: With BATTERY in EXT PWR nothing comes on until EXTERNAL POWER is ON; the DC buses then run from the ground cart and the battery rests.
4 WARNING PANEL - CHECK DC GEN and MAIN AC come on with the power; with the engine stopped HYD, OIL, AMAD, SEC and OXY are normal too → Warnings and Alerts
5 MAIN AC GENERATOR - OFF-RESET It cannot connect while external power is on
6 STANDBY GENERATOR AND EMERGENCY INVERTER - OFF Cold-and-dark position; TEST, then NORM after engine start
Note: No ground power: BATTERY NORM instead. Every display, the INS, BCDU and IFF then run on the battery, but AFCS POWER and EW CONT have no AC, the MON DC bus stays dead (MON DC after 15 s, no exterior lights, no SEAT ADJ) and the battery drains.
AVIONICS - RIGHT CONSOLE
7 BCDU - ON 5 s display test, then INITIALIZING 9 ... 1 (about 15 s). While the AVP is off it shows its menu pages (backup control) → Backup Control Display Unit (BCDU)
8 INS - LOAD, THEN ON Three positions ON / OFF / LOAD. LOAD springs back to OFF after loading present position and date - then select ON. MFD NAV > INIT later shows INS MODE STBY → Inertial Navigation System (INS)
9 INS ALIGNMENT - START BCDU NAV-1 > L1 NAV INIT > R5 STBY MODE< (ALN MODE) > ENT, while the AVP is still off. Otherwise start it on the MFD below
Caution: Do not move the aircraft: above 3 kt the INS alignment starts again (ACFT MOVED), and any movement restarts the SFD initialization.
10 SFD - ON About 6 s POWER ON BIT, then ATTITUDE INITIALIZING 10 s (Realistic 3 min); speed, altitude and heading show at once → Standby Flight Display (SFD)
11 AVP - ON Up after 7 s (Realistic 2 min). Until then the MFDs show DISPLAY BUS OR AVP FAILURE and the UFCD NO COM → Multi-Function Displays (MFDs)
12 UFCD - ON 9 s self-test, then NO COM until the AVP is up → Up-Front Control Display (UFCD)
13 IFF - ON Comes up in STBY. OFF / ON / HOLD (HOLD springs back to ON); squawk NORM later on the UFCD IFF page
14 AFCS POWER - ON Needs AC (ground power or generator) → AFCS System (Autopilot)
Note: The AUTOPILOT lamp stays on while the PITCH, ROLL and YAW axis switches are OFF (as left by cold and dark); they go ON in the AUTOPILOT GROUND CHECK.
15 MFD OFF / NIGHT / DAY KNOBS - D (OR N) Small knob top right of each bezel, all three. Each MFD runs a 9 s POWER ON BIT (raster, colour bars, grid, characters, BIT list, BIT COMPLETE), then DISPLAY BUS OR AVP FAILURE until the AVP is up → Multi-Function Displays (MFDs)
Note: When the AVP is up the PFD shows RESET BARO and a red ALT box until the altimeter setting is changed - set the baro in MFD PAGES (at 29.92 move it off and back).
16 EW CONT - REC (AS REQUIRED) Needs ESS AC and DC ESS. Startup self-test first: 30 s (Realistic 5 min), tooltip REC - SBIT, EW page EWS STARTUP BIT m:ss. The threat tone also needs MISSION RECORDER (MSN RCD) ON
ALIGNMENT
17 INS ALIGNMENT - MONITOR MFD NAV > INIT (T6): INS MODE, AQ counting down from 300. Not started yet: R1 ALN, R2 YES. ALIGN MISMATCH = entered position more than 1 NM out → Inertial Navigation System (INS)
Note: Full alignment: attitude 30 s after ALN, LIM NAV READY 5 min, FULL NAV READY 22 min (Short: about 40 s / 3 min). Accept with R1 ACPT, R2 YES before taxi (MFD PAGES, NAV); GPS updating then keeps the position.
18 AUDIO CONTROL PANEL - SET Volume panel, left console: COMM 1, COMM 2, TACAN, ILS, AOA and THREAT off the stop (volume = knob x MASTER VOLUME)
Note: At the stop TACAN and ILS switch off (TACAN FAULT advisory) and AOA silences the approach tones (the stall tone stays). HF has no function.
Note: The MFD status and route pages (STAT VERS / LOAD / HIST / FAULT, NAV DPS) are checked in MFD PAGES, once the AVP is up.
