Explain the FF from the Tanks to the Engines:

Main Tank to Collector Tank (360 lbs) to Engine Engines running: EDP creates Motive Flow (suction). Scavenge Ejector delivers fuel from Main Tank to Collector Tank by Motive Flow. Main Ejector delivers fuel from Collector Tank to Engine by Motive Flow. Engines not running: Collector Tank is gravity-supplied from Main Tank by flapper check valves. Fuel pump delivers fuel from Collector Tank to Engine (when either FUEL PUMP is ON or ENG RUN in RUN). Surge tanks allow for expansion.

Where are the Scavenge Ejectors located, what is their primary purpose?

- Bottom of the Main Tank | - Deliver fuel from Main Tank to Collector Tank by Motive Flow

Where are the Main Ejectors located, what is their primary purpose?

- Bottom of the Collector Tank | - Deliver fuel from Collector Tank to the Engines by Motive Flow

Hydraulic pressure?

3000 psi

What is powering the HYD SYS?

- Onside EDP - Onside DCMP DCMP is supplied by opposite GEN - if opposite GEN fails onside GEN takes over.

What is powering the AUX DCMP?

L GEN If L GEN fails, R GEN or APU GEN takes over.

When does L/R HYD PUMP turn ON in AUTO mode, when does AUX DCMP turn on/off?

L/R HYD PUMP ON: - Flaps above 0 (F10/20/30 selected) - Low HYD PRESS. AUX DCMP: - ON 2.500 psi - OFF 3.350 psi

What is the Ecology Bottle's purpose?

Collecting HYD fluid leakage

During cockpit preperation - why turning on R PUMP before AUX PUMP?

To prevent cavitation

What is the PTU; how does it work; when is it ON?

Power Transfer Unit PTU supplies pressure to operate landing gear if L HYD SYS fails. This allows normal retraction time as DCMP alone would be very slow retracting landing gear. PTU supplies L HYD SYS from R HYD SYS. R HYD SYS pressure is protected by priority valve. PTU is ON when: - PTU in AUTO - L EDP and/or ENG OFF - R EDP ON - Gear not in commanded position - Airborne

A/I - what is heated by: - Bleed Air - Electrical Power

Bleed Air: - ENG - WING Electrical Power: - WSHLD/WINDOW - PROBES

When does the WSHLD/WINDOW operate in high mode?

WING, ENG, PROBES and WSHLD/WINDOW ON

What parts are heated by: - L/R ENG - WING - PROBES - WSHLD/WINDOW

L/R ENG: - Engine Inlets (fails open) - T2 Sensors WING: - Leading Edges (fails closed) PROBES: - Pitot-Static Probes - Standby-Pitot Probe - Standby-Static-Flush Ports - AOA Vanes - TAT Sensor (inflight only) (Ice Detectors) WSHLD/WINDOW: - Windshields - Side Windows

What is the EMER LTS power source; when do they turn on automatically; how long can they operate independently?

- Two independent rechargeable battery packs - ON when ARM and power to R MAIN DC BUS is lost - 15 minutes

NLG - Maximum angles with Pedals and Tiller?

+/- 7 deg. | +/- 65 deg.

How does the alternate gear extension work?

NLG gravity, MLG gravity and hydraulic (R HYD SYS). | Do not push handle back in during operation.

EMER BRAKE and toe brakes - what are the limitations with HYD SYS failures?

EMER BRAKE: No antiskid protection. Toe brakes: L HYD only allows for 6 applications. No HYD allows for 1 application.

How to set the PARK Brake and why?

Depress Toe Brakes before setting/releasing the brakes This prevents HYD fluid migration from R to the L HYD SYS

What is supplied by L HYD SYS?

- Inboard Brakes - Inboard MFS - Inboard GS - Inboard ELEV PCU - LH T/R - Upper Rudder PCU - ALTN FLAPS - NWS - GEAR - EMER BRAKE

What is supplied by R HYD SYS?

- Outboard Brakes - Outboard MFS - Outboard GS - Outboard ELEV PCU - RH T/R - Lower Rudder PCU - Flaps - PTU - Gear Assist Actuators (Alternate Gear Extension)

What is supplied by AUX HYD SYS?

Lower Rudder PCU

Maximum Rudder deflection with YD engaged?

+/- 5 deg.

What does the YD when accelerating above 60 kts?

Damping function is smoothly disabled until weight is off wheels, at which point it is re-enabled.
