Wing/Empennage Anti-Ice

A

(In visible moisture and OAT =/<10°C)

Should be turned on in sufficient time prior to landing to ensure the vertical stab is completely anti-iced. May take as long as 2.5 min.

Failure to do so will cause X-WIND LIMITED ACAWS message when landing gear are lowered and the side slip system will limit crosswind landing capability if icing is detected.

Q

Bleed Air Augmenter Valves

A

When the [wing/emp ice protection] system is operating and HP is less than 1,000, the engine bleed air augmenter valve opens and regulates high pressure bleed air to a predetermined pressure schedule as a function of altitude. If bleed air temperature is less than 274 °C (525 °F), the engine augmenter valve opens to increase temperature, but not pressure.

Q

Bleed Air Leak Detection (if a leak is detected)

A

When operating in AUTO, the F/ODS signals the isolation and/or divider valves to close.

The F/ODS also signals the nacelle shutoff valves to close through the MC and BA/ECS.

Automatic isolation occurs as follows:

LEFT WING: the No. 1 and No. 2 nacelle shutoff, high stage augmenter, and left wing isolation valves close.

RIGHT WING: the No. 3 and No. 4 nacelle shutoff, high stage augmenter, and right wing isolation valves close.

L X-SHIP: the divider, left wing isolation, and APU bleed air shutoff valves close.

R X-SHIP/CARGO COMPARTMENT: the divider valve and right wing isolation valves close.

CARGO FLOOR: the floor heat shutoff valve closes.

Q

Takeoff and Landing Fuel Management

A
  1. Maximum usable fuel weights are listed in paragraph 4.1.1.3 FuelWeightLimits.
  2. Tanks No.1 and No.4 always contain 500 to 1,000 pounds more fuel per tank than tanks No.2 and No.3.
  3. The main tanks are full, except for fuel used for taxi, takeoff, and climb; but not less than 7,060 pounds in tanks No. 1 and No. 4, and not less than 6,410 pounds in tanks No. 2 and No. 3 when the external tanks contain usable fuel.
  4. Fuel unbalance is within the limits specified in paragraph 4.2 AIRSPEED LIMITATIONS and paragraph 4.13.3 Fuel Unbalance Limits.
  5. Refer to the takeoff and landing fuel management chart to determine sink rate limitations regardless of

[-6.5-3-

or not].

78
Q

Severe Turbulence Penetration

A

If severe turbulence cannot be avoided, flight should be in the range of 65 KIAS above power-off stall speed for the operating gross weight, not to exceed 180 KIAS.

79
Q

Enroute Fuel Management

A
  1. Maximum usable fuel weights are listed in paragraph 4.1.1.3 FuelWeightLimits.
  2. When the external and/or auxiliary tanks contain usable fuel, tanks No. 1 and No. 4 are maintained at a maximum fuel level of 8,310 and contain 500 to 1,000 pounds more fuel per tank than tanks No. 2 and No. 3.
  3. When external and/or auxiliary tanks do not contain usable fuel, tanks No.1 and No.4 are maintained at a maximum fuel level of 8,310 pounds while tanks No. 2 and No. 3 are reduced to a level of 1,520 pounds. Fuel from tanks No. 1 and No. 4 will then supply the motors until all main tanks reach a level of 1,520 pounds. When all the main tanks fuel quantities reach 1,520 pounds, establish direct tank-to-engine feed.
  4. Fuel unbalance is within the limits specified in paragraph 4.2 AIRSPEED LIMITATIONS and paragraph 4.13.3 Fuel Unbalance Limits.
  5. If these limits are used during landing with 8,310 pounds in the outboard tanks, refer to the enroute fuel management chart to determine sink rate limitations.
80
Q

Secondary Fuel Management

A
  1. Any fuel management that fails to meet the requirement for takeoff and landing, or enroute fuel management is defined as secondary fuel management. This will occur any time there is usable fuel in the external tanks and the main tanks are partly filled to less than 26,940 pounds. An extreme deviation into secondary fuel management would be operation with tanks No. 1 and No. 4 empty.

Note

The aircraft should be flown with tanks No. 1 and No. 4 empty only in an emergency or when it must be ferried to another facility for repair of a fuel leak in either of these tanks.

Effects of secondary fuel management on service life and inspection requirements have not been established. Secondary fuel management should be used advisedly, especially when operating near the gross weight limit for the applicable maneuver or airspeed.

81
Q

Fuel Unbalance Limits

A
  1. 1,000 pounds between tanks of a symmetrical pair (main or external).
  2. 1,500 pounds between the left and right wings except as stated in item 3.
  3. One auxiliary tank full and the other auxiliary tank empty, provided all other tanks are symmetrically fueled or unbalanced toward the opposite side within the above limits.

transmit shaft power from the torquemeter to the propeller,

reduce shaft RPM, and

provide shaft power to the GMAD.

85
Q

Heavy Rain

A

When possible, avoid flying through heavy rain or extreme precipitation. Extreme precipitation is identified as

comparable to water content that may be found in Level 6 thunderstorm activity and will be depicted on the LPCR

in magenta. Heavy rain can:

  1. Reduce lift by up to 30 percent at high angles of attack such as during approach or missed approach profiles.
  2. Increase drag up to 30 percent.
  3. Cause the aircraft to slow down faster than normal when engine power is reduced.
  4. Cause engine rollback and flameout.
  5. Cause turbulence.
86
Q

Extreme Precipitation

A

If extreme precipitation is encountered and cannot be avoided:

  1. Reduce power as required to reduce airspeed to 180 KIAS.
  2. Maintain engine power above 700 horsepower.

Engine power rollback and flameout may occur when operating in extreme

precipitation conditions.

Note

Autothrottles should be disengaged.

If extreme precipitation is encountered and cannot be avoided, refer to the Turbulence and Thunderstorm procedures

in this chapter.

87
Q

Oil Cooler Flap Operation In AUTO

A

On the ground, the AUTO mode opens the oil cooler flap when the oil cooler outlet temperature is greater than 75 °C and retracts the oil cooler flap when the oil cooler outlet temperature is less than 60 °C. This schedule is optimized for ground conditions, where the coolest temperature is achieved when the oil cooler flap is 100 percent open.

In the air with landing gear extended, the AUTO mode opens the oil cooler flap when the oil cooler outlet temperature is greater than 82 °C, and retracts the oil cooler flap when the oil cooler outlet temperature is less than 76 °C. This schedule is optimized for the landing configuration.

In flight, airflow begins to decrease in the oil cooler duct if the oil cooler flap is opened. In the air, with landing gear retracted, the AUTO mode closes the oil cooler flap for optimum inflight cooling.

88
Q

Prop Control Lost ACAWS

A

Propeller control is lost as determined by the FADEC. If the NP drops below 73 percent with power lever angle greater than 55, this message is accompanied by the red FAIL message under the HP display, the white box around the engine instruments and during takeoff by the ENG 1 (2, 3 or 4) FAILSpecial Alert.

89
Q

Landing Gear Aural Warning and Hush Button

A

Two things will cause the landing gear aural warning message when the landing gear is not down and locked

1) Retarding an engine power levers to within 5° of the FLT IDLE position below 1,500 feet AGL,
2) extending the flaps more than approximately 70 percent without refueling pods attached or 80 percent with refueling pods attached.

A HUSH switch is located on the back side of each pilots’ control wheel. It is a press-type switch used to silence the landing gear aural warning when a power lever is retarded. It will not silence the aural message when flaps are extended more than 70 or 80 percent respectively.

90
Q

Landing Gear Warning Light

A

The landing gear warning lights illuminate

1) when any landing gear is not in the selected position,
2) when an engine power lever is retarded to within 5° of the FLT IDLE position and the landing gear is not down, or
3) when the landing gear is not down and the flaps are greater than 70 percent.

91
Q

Hydraulic Fuses

A

Hydraulic fuses are provided in the normal and emergency systems for each of the main landing gear brakes. If a failure is experienced in the hydraulic line between the fuse and the brake, the fuse will allow approximately 10 cubic inches of fluid to bleed out of the system and then close, thereby retaining the remaining hydraulic fluid for operation of the other three brakes.

92
Q

An unusual attitude condition is one or more of the following:

A
  1. Pitch: <-20 or >+32°.
  2. Bank: >±65°.
  3. Bank ±40° with autopilot engaged or the autopilot disengage light on.
  4. Pitch/flight path: >15° difference.
93
Q

The unusual attitude mode is terminated when all of the following conditions exist:

A
  1. Pitch angle <15°.
  2. Bank angle <60° (when autopilot not engaged and autopilot disengage light not on).
  3. Bank angle <37° (when autopilot engaged or autopilot disengage light on).
  4. Angle between vertical flight path and aircraft longitudinal axis <15°.
94
Q

  2. Air conditioner discharge temperature is excessive (approximately 210 °F for the flight station air

conditioner, and 380 °F for the cargo compartment air conditioner).

  1. Any ENGINE START switch is in START position.
97
Q

Underfloor Heat

A

The HEAT/FAN position opens the shutoff valve, and the underfloor heat sensor modulates the floor heat temperature control valve to maintain an underfloor temperature of 73 ±8 °F (23 ±5 °C)

98
Q

Auxiliary Ventilation

A

The auxiliary ventilation provision in each system consists of a valve connecting the heat exchanger cooling air inlet to the conditioned air distribution ducts. When the valve is opened, most of the air entering the cooling air scoop flows directly into the distribution ducts. In flight, the air thus admitted to the aircraft is ambient air under ram pressure.

99
Q

Windshield Defogging Levers

A

A WINDSHIELD DE-FOGGING lever on the pilot and copilot side consoles controls a valve connecting the temperature-conditioned air duct to the windshield defogging outlets on that side of the flight station. With the lever moved to ON, the valve is opened.

100
Q

Outflow Valve

A

The outflow valve, located on the right aft side of the flight station exhausts cabin air to the atmosphere through a louver in the skin (Figure 2-76). The valve consists of a butterfly valve, a main actuating diaphragm and pneumatic relay for automatic control, an air jet pump, and an electric actuator for manual control

101
Q

Cabin Pressure Controller

A

The dual-channel cabin pressure controller is an electronic computer providing fully automatic cabin pressure control. The controller is used in conjunction with the dual servo valve to provide automatic operation for a variety of situations

102
Q

Safety Valve

A

Electronically Controlled and pneumatically opened for emer depress.

It opens to relieve cabin pressure when positive differential pressure reaches 14.96 in. Hg or negative differential pressure reaches 0.76 in. Hg. The safety valve also opens when emergency depressurization, auxiliary ventilation, or no-pressure operation is selected or, when in AUTO with weight on wheels and the bleed air manifold is pressurized.

103
Q

Manual Valve Control Rocker Switch

A

controls the

electric actuator of the outflow valve when the pressurization mode select switch is in the MAN position. When the manual valve control rocker switch is held in the CLOSE position, the actuator turns the outflow butterfly valve toward its closed position to decrease cabin altitude. When the switch is held in the OPEN position, the actuator turns the butterfly valve towards its open position to increase the cabin altitude.

104
Q

AUTO RATE Selector

A

Setting the AUTO RATE selector to NORM, selects a nominal climb rate of 500 fpm and a nominal descent rate of 300 fpm. When the AUTO RATE selector is set at MIN, the rate is zero fpm. When the AUTO RATE is set to MAX, the cabin rate is limited to 3,000 fpm.

105

108
Q

FADEC Autofeather Request — The FADEC will request MC permission to autofeather if the power lever is at FLT IDLE or above and any of the following exists:

A

a. Loss of propeller control (high power and NP below 73 percent).
b. At low power settings, low NG (less than 69 percent).
c. At high power settings, low engine HP (less than 74 percent of commanded HP) and decelerating NG

(greater than 500 rpm per second).

109
Q

Mission Computer Autofeather Permission

A

The outboard propellers always have MC permission to autofeather without delay. This supports low minimum control speeds. For the inboard propellers, autofeather permission is granted after a two second delay provided the aircraft is below 15,500 feet andthe other engines are running normally. If these conditions are not met the FADEC will windmill thepropeller at 100 percent rpm. This ensures the inboard propeller autofeathers if an engine fails on takeoff. If all engines flameout at least one inboard propeller will be at 100 percent RPM supplying electric and hydraulic power.

110
Q

Reversionary NG Control

A

The FADEC reversion control mode allows continued safe flight with both engine torque sensors failed. The reversion mode bases fuel scheduling on NG instead of the normal torque setting. The FADEC fault control logic automatically engages the reversion mode, but closer monitoring of power lever angle and NG is required to ensure symmetric power settings. Maximum available propeller horsepower is reduced by approximately 40 percent to ensure that engine power limits are never exceeded. Reverse power is not available.

111
Q

Automatic Start Control

A

For air starts the start sequence is initiated just as it is on the ground except that the FADEC will not shut down the engine for a stagnated start. The FADEC sequences the starter regulating and shutoff valve, ignition, fuel flow, and compressor variable geometry vanes to start the engine.

112
Q

Nacelle Interface Unit

A
  1. Provides MIL-STD-1553 and RS422 communications.
  2. Provides indications of oil temperature, pressure and quantity, oil cooler flap position and fuel flow.
  3. Controls oil cooler flap and engine/nacelle anti-ice valves.
  4. Provides engine health and usage monitoring through the EMS. Related functions include diagnostics and fault monitoring, performance monitoring, trend data acquisition, life usage assessment, and propeller balancing data. In addition to the displayed engine parameters; compressor discharge pressure and temperature, vibration sensors, and the CADC system support the EMS.
113
Q

Insufficient Oil Scavenging

A

The oil system in the core engine and the gearbox scavenge oil back to the oil tank when NP and NG are in the normal operating ranges. With the engine shut down in flight the engine and propeller can windmill at different speeds, depending on the conditions or failures. These intermediate rpm conditions result in oil pooling in sections of the engine if the FIRE handle is not pulled.

114
Q

Oil Capacity

A

20-gallon oil tank is located in each nacelle above the engine. The tank has a 12-gallon oil capacity with the remainder of the tank, approximately 8 gallons, used for air space. The oil tank also incorporates a 0.66-gallon dedicated reservoir for the emergency feather pump oil supply

115
Q

Ignition System

A

The ignition system consists of two ignitors, two ignition leads, two ignition exciters, and one PMA.

116
Q

Compressor Acceleration Bleed Air System

A

The compressor acceleration bleed air system consists of the compressor acceleration bleed control valve and two compressor bleed valves. The CABCV-controlled compressor bleed valves allow 10th-stage bleed air into the nacelle cavity during initial starting, to allow surge-free acceleration to idle speed. After the engine gas generator has reached sufficient speed, 14th-stage bleed pressure closes the valves.

117
Q

MGT (Measured Gas Temperature)

A

MGT is the measure of engine temperature. It represents the temperature of the gases at the third stage power turbine vanes.

118
Q

Ground Beta Enable Valve

A

The GBEV removes the hydraulic low pitch stop (13.0° ±2°) and isolates the OSG during ground beta operations to prevent it from reacting to overspeed transients. It is operated by a dual coil solenoid.

119
Q

Magnetic Pulse Unit

A

The dual channel MPU, mounted on the propeller brush block, detects the passing of each blade as the propeller rotates. Each channel is connected, via a separate connector, to an individual FADEC channel.

120
Q

Fuel Transfer Switches

A

The FLCV switch is labeled TO.

The transfer pump switch is labeled FROM.

The two switches are set in combination to allow the following three fuel transfer states for each tank.

121
Q

SPR Drain

A

Fuel drained from the SPR manifold is returned to the No. 3 main fuel tank.

Cycle takes 2.5 minutes

122
Q

What Supplies APU Starting Power?

A

The isolated dc bus supplies APU starting control power.

123
Q

What is ppowered initially when battery power is switched on?

A

When the battery is turned on and no other electrical power is available on the aircraft, the pilot CNI-MU, HDD 1, and HDD 2 are powered.

124
Q

APU Operational Altitudes

A

The APU will start and operate at altitudes from -1,000 feet to 20,000 feet.

125
Q

What does the APU Power?

A

If the APU is the only source of power it will power the essential and the main ac buses.

Notes:

If the APU generator is on line, the APU will power the essential ac bus regardless of the on/off condition of the other generators.

If only the APU is on line, then the APU will power the essential and main ac buses.

126
Q

Bus Tie

A

Except during battery only start of the APU, the isolated and avionics dc buses are isolated by a bus tie relay. When a start of the APU is initiated and ac power is not present, the APU start logic closes the bus tie relay and selects the utility battery as a dedicated power source for the APU start motor. The closed bus tie relay allows the avionics battery to power both the isolated and avionics dc buses.

127
Q

Auxiliary Hydraulic Pump Switches

A

The auxiliary hydraulic pump may be controlled by either of two control panel switches. One two-position (ON or OFF), rocker switch labeled AUX PUMP, is located on the HYDRAULIC control panel. The other switch, labeled PUMP, is a two-position (ON or OFF) toggle switch located on the ramp control panel.

128
Q

Aileron Booster Assy

A

The aileron booster assembly hydraulic actuating cylinder furnishes most of the force to move the ailerons. The booster assembly is furnished fluid through a pressure-reducer at approximately 2,050 psi from both the booster and utility hydraulic systems.

129
Q

Aileron Diverter Valve System

A

The ADV system provides improved handling qualities at speeds below 270 knots when the autopilot is not engaged. ADV system activation is controlled by the MC with inputs from propeller speed, autopilot lateral axis state, and flap position parameters.

**Allows hyd px to bypass the px reducer, effectively increasing pressure from 2050PSI to 3000PSI.

130
Q

Automatic elevator trim tab system

A

Any time the flaps are lowered to 75 percent or more, as shown on the flap position indicator, an automatic elevator trim tab system is armed. When the flaps are raised from this position, the elevator trim tab is actuated to give nose-down trim. The elevator tab will actuate for a maximum of 2.8 seconds (approximately 7°), or until flap movement stops, or until the flaps reach 50 to 55 percent, whichever occurs first. If the flaps are raised from a position below 75 percent in small increments, the automatic trim system will remain

131
Q

Stall Warning and Stick Pusher Speeds

A

Stall warning and stick pusher speeds are calculated continuously by the MC from AOA sensor data, engine power, and flap position. The speeds are accurate for all conditions of flight, including all weights, angles of bank, levels of g, power settings, and flap settings. The stall warning speed is approximately 1.08 times the instantaneous stickpusher speed.
