Which probe is fitted in the inlet cowl? P12/T12 T(amb) P20/T20. How is Fan Trim Balancing achieved? Fitting Balance correction screws on the Intake Spinner Extension Fitting balance whasers on the fan blade retention screws Fitting Balance weights on the LP Shaft hub face. The fuel filter differential switch sends it signal directly to which of the following components? The EEC AIMS The FMU. Where is P50 sensed? At the P50/T50 probe At the LPT Bearing support vanes At the LPT Inlet Guide Vanes. Temperature rise shown on the maintenance pages relates to which of the following answers? The oil out temperature of the IDG The difference between the oil out probe and the oil in probe to the oil cooler The expected temperature due to electrical demand. How is Oil breathing achieved? The pressurisation valve exceeds 42 psi A centrifugal beather in the gearbox A centrifugal breather in the oil tank. Which of the following statements is correct? Turbine Impingement cooling: Is not operative in the cruise Is an Uncontrolled system flooding ambient air onto the compressor casings Uses Fan discharge air to cool the turbine cases. Manual reversion requires, which of the following to be performed? Isolation shut off valve selected top chut off position and the centre actuators locks have been removed "1/2" manual plunger has been depressed and locked ad the DVC is locked closed Isolation valve selected to bypass, Synch lock levers manually position to open and 3/8 drive plunger must be depressed. What controls the continuous ignition during heavy rain? The T30 thermocouples The IPC exit thermocouples The T44 thermocouples. Which of the following statements is correct? The turbine overheat detection system: Is a pair of thermocouples monitoring air temperature at the HPT vane front and aft face Is monitored by the EEC sending an overheat signal to the Fire Detection Cards for Fire warning generation Is a single thermocouple measuring air temperature at the IPT vane front face. Which of the following does the dedicated generator NOT directly provide a power supply to? The EEC The PCU The OPU. Where can the reverser sleeve position be observed?
