Engine/Jet Start

This panel is used when starting the A/C engine. Depending on the type of turbine the panel may have little variations, as the different engines are also started in a different way. This panel is located on the left console.

Engine Start


ElementTypePositionInformation
RUNLight
(green)
 Illuminates green within 30 seconds after initiating JFS start to indicate that the JFS has attained governed speed
JFS3-Way switchSTART 1Vents one of the hydraulic accumulators to the hydraulic start motor
OFFNormal switch position. The JFS can be shut down at anytime by selecting OFF. The switch will return to OFF automatically during a normal ground start at 50 percent rpm.
START 2Vents booth hydraulic accumulators to the hydraulic start motor. This position is used for ground starts in extreme temperatures or after a start 1 failure. START 2 is also used for JFS-assisted airstarts.
EEC BUC3-Way switch
(Safety bar)
EEC (Safe)EEC (electronic engine control) in operation (normal position)
OFFEEC (electronic engine control) not in use (basic UFC operation)
BUC80: Transfer occurs when throttle is in OFF or above BUC IDLE.
LESS 80: If rpm is above 52 percent and throttle position is at or above BUC IDLE, transfer to BUC occurs. If rpm is below 52 persent, transfer occurs regardless of throttle position.
STARTING FUEL3-Way switchAUTO LEANIf UFC (EEC ON or OFF), lean fuel flow is provided during the engine start cycle until 30 seconds after the main generator comes on the line. Fuel flow then increases by 100 pph (rich fuel flow). In BUC, rich starting fuel flow is provided.
RICHFuel flow is rich at all times
LEANFuel flow is lean at all times
MAX POWER2-Way switch
(Safety frame)
MAX POWERDelivers maximum thrust (VMAX) when at 1.1 mach or above and the throttle is at MAX AB
OFFNormal (deenergized) position
