C F M 56-5B ENGINE CONTROLS - GENERAL - DESCRIPTION AND OPERATION _____________________________________________________

1. General _______ The engine control system consist of : - the throttle control - the HP fuel shutoff valve control - the LP fuel control.

A. Throttle Control Lever (Ref. Fig. 001) The throttle control system is fully electrical. The throttle control lever drives the position detectors. The position detectors are located under the cockpit center pedestal. Two of the resolvers are dedicated to the FADEC system. Each channel of the Electronic Control Unit receives the position signal from one resolver in the analog form.

B. ENG/MASTER Control Switch (Ref. Fig. 002) The MASTER control switch interfaces with the HP fuel shutoff valve and the Engine Interface Unit (EIU). It controls directly the closure of the fuel shutoff valve : it energizes the valve solenoid. An analog signal informs the EIU of the position of the MASTER control switch. The EIU transmits then the information to the ECU in digital form. The ECU uses this information to initiate the automatic and manual engine starting sequences. The MASTER control switches are part of the panel 115VU, switchR replacement requires removal of panel 115VU.

C. LP Fuel Shutoff Valve Control The LP fuel shutoff valve is electrically controlled :

- either by the ENG/MASTER control switch on the ENG panel - or by the ENG FIRE pushbutton switch.

C F M 56-5B POWER CONTROL - DESCRIPTION AND OPERATION _________________________________________

1. General _______ (Ref. Fig. 001)

A. Manual Thrust Setting Mode (the autothrust function is not active) The throttle control lever in the cockpit center pedestal controls :

- the engine level of thrust - the thrust limit mode. The Electronic Control Unit (ECU): - receives the throttle lever angle - computes the engine thrust limit parameter and adjusts the actual engine thrust parameter accordingly.

B. Automatic Thrust Setting Mode (the autothrust function is active) The throttle control lever controls : - the actual thrust limit - the thrust limit mode. The FMGC computes the target thrust parameter and sends it to the ECU. The ECU adjusts the actual engine thrust parameter according to this value (Ref. 73-20-00). The top limit value of the target thrust parameter is the actual position of the throttle control lever (this is applicable when the alpha floor protection is not activated).

Thrust Setting Block Diagram Figure 001




C F M 56-5B THROTTLE CONTROL - DESCRIPTION AND OPERATION ____________________________________________

1. General _______ (Ref. Fig. 001) The throttle control system consist of : - the throttle control lever - the throttle control artificial feel unit

- the throttle control unit - the electrical harness. In addition each throttle control lever is fitted with an instinctive pushbutton switch. This pushbutton switch serves for the de-activation and disengagement of the autothrust function. The design of the throttle control is based upon a fixed throttle concept : this means that the throttle control levers are not servo motorized.

2. Throttle Control Mechanical Parts _________________________________

A. Throttle Control Lever (Ref. Fig. 002, 003) The throttle control handle comprises : - a throttle control lever which incorporates stop devices and autothrust instinctive disconnect pushbutton switch - a graduated fixed sector - a reverse latching lever. The throttle control lever moves over a range from : - -20 deg. TLA (Reverser Full Throttle stop) to 45 deg. TLA (Forward Full Throttle stop). An intermediate mechanical stop is fitted at 0 deg. TLA. This stop is overriden when the reverse latching lever is pulled up for selection of the reverse power. This idle stop is reset as soon as the lever is selected back to forward

thrust area. In the forward thrust area, there are two detent points : - MAX CLIMB detent point set at 25 deg. TLA - MAX CONTINUOUS/FLEX TAKE OFF detent point set at 35 deg. TLA. In the reverse thrust throttle range, there is one detent point : - -6 deg. TLA, this position corresponds to the selection of the thrust reverser command and the Reverse Idle setting. From -20 deg. TLA to 0 deg. TLA, the autothrust function cannot be activated. In the middle throttle range (0 deg. to 35 deg. TLA), the autothrust function can be active if engaged. This range corresponds to the selection of MAX CLIMB or MAX CONTINUOUS thrust limit mode (except the FLEX TAKE OFF mode).

If the autothrust is not engaged, the engine control is manual.

Throttle Control System Figure 003




C F M 56-5B In the forward range (35 deg. to 45 deg. TLA), the autothrust function cannot be activated (except in alpha floor condition). This range corresponds to the selection of FLEX TAKE OFF/MAX TAKE OFF (GO AROUND) mode. The throttle control lever is linked to a mechanical rod. This rod drives the input lever of the throttle control artificial feel unit.

B. Throttle Control Artificial Feel Unit (Ref. Fig. 004) The Throttle control artificial feel unit is located below the cockpit center pedestal. this artificial feel unit is connected to engine 1(2) throttle control lever and to the engine 1(2) throttle control unit by means of rods. The artificial feel unit is a friction system wich provides a load feedback to the throttle control lever. This artificial feel unit comprises two symetrical casings, one left and one right. Each casing contains an identical and independent mechanism. Each mechanism is composed of: - a friction brake assembly - a gear assembly - a lever assembly - a bellcrank assembly Throttle control lever travel is transmitted to the artificial feel unit and to the throttle control unit. The linear movement of the throttle control levers is transformed into a rotary movement at the bellcrank which turns around the friction brake assembly shaft. This movement rotates a toothed quadrant integral with the shaft. This toothed quadrant causes inverse rotation of a gear equipped with a disk which has four detent notches. Each notch corresponds to a throttle control lever setting and is felt as a friction point at the throttle control levers.

C. Throttle Control Unit (Ref. Fig. 005, 006, 007) A mechanical rod transmits the throttle control lever movement. It connects the throttle control artificial feel unit to the input lever of the throttle control unit. The throttle control unit comprises : - an input lever - mechanical stops which limit the angular range - 2 resolvers whose signals are dedicated to the ECU (one resolver per channel of the ECU)

- 6 potentiometers fitted three by three. Their signals are used by the flight control system

C F M 56-5B - a device which drives the resolver and the potentiometer - a pin device for rigging the resolvers and potentiometers - 1 switch whose signal is dedicated to the EIU. - a safety device which leads the resolvers outside the normal operating range in case of failure of the driving device - two output electrical connectors. The input lever drives two gear sectors assembled face to face. Each

sector drives itself a set of one resolver and three potentiometers. The relationship between the throttle lever angle and throttle resolver angle (TRA) is linear and : 1 deg. TLA = 1.9 TRA. The accuracy of the throttle control unit (error between the input lever position and the resolver angle) is 0.5 deg. TRA. The maximum discrepancy between the signals generated by the two resolvers is 0.25 deg. TRA. The TLA resolver operates in two quadrants : the first quadrant serves for positive angles and the fourth quadrant for negative angles. Each resolver is dedicated to one channel of the ECU and receives its electrical excitation from the ECU. The ECU considers a throttle resolver angle value : - less than -47.5 deg. TRA or - greater than 98.8 deg. TRA as resolver position signal failure. The ECU incorporates a resolver fault accomodation logic. This logic allows engine operation after a failure or a complete loss of the throttle resolver position signal.

C F M 56-5B ENGINE MASTER CONTROL - DESCRIPTION AND OPERATION _________________________________________________

1. HP Fuel Shut OFF Valve Control ______________________________

A. General (Ref. Fig. 001) The HP fuel shutoff valve control is fully electrical (the HP shutoff

valve is a part of the HMU described in Ref. 73-20-00). It is performed from the engine panel in the cockpit as follows : - opening of the HP fuel SOV : it is controlled by the ECU : the ECU receives the commands from the ENG/MASTER control switch and ENG/MODE/CRANK/NORM/IGN START selector switch. - closure of the HP fuel SOV : it is controlled directly from the ENG/MASTER control switch in OFF position (Ref. 73-20-00 and 80-00-00).

B. Valve Operation (Ref. Fig. 002) The FADEC control system contains two fuel shut-off means, which act through pilot valves to close the pressurizing valve :

(1) A fuel shutoff which is directly hardwired to the ENG/MASTER control switch. This solenoid operated pilot valve is powered by the 28VDC. It is closed when powered.

(2) When the main metering valve is positioned below a minimum fuel flow position : a mechanically operated pilot valve in the HMU closes the pressurizing valve. This function is software logic inhibited to prevent operation at and above idle operation. The fuel shutoff valve meets the following concepts.

- The pressurizing valve does not actuate open with boost pressure (even if both pilot valves call for ON) until the HP fuel pump provides sufficient pressure to open it. - Loss of power supply does not lead to change the selected HP fuel shutoff valve position. - When HP fuel shutoff valve is selected closed (open) a spurious transient voltage to open (close) does not lead to a permanent opening (closure) of the fuel valve. - The cockpit commanded OFF coil has priority over the ECU command. The cockpit control interfaces directly with the HP fuel shutoff solenoid. The valve contains a coil which operates the HP shutoff closed when energized. The solenoid is of a latching type. It latches either open or closed until a reversing signal is applied. The open

function is a hydraulic trip with a magnetic latch. A closed signal has priority.

C F M 56-5B 2. LP Fuel Shut Off Valve Control ______________________________ (Ref. ATA 28)

A. General The function of the LP fuel shutoff valve is to control the fuel supply at engine-to-pylon interface. The valve is located on the engine supply system in the wing leading

edge.

B. Valve Operation (Ref. Fig. 001) The LP fuel shutoff valve is controlled : - From the cockpit overhead panel by means of the ENG FIRE pushbutton switch - From the cockpit center pedestal by means of the ENG/MASTER control switch on engine control panel.
