77 Engine Indicating Flashcards
Summary of oil temp indicating for the fusion system.
oil temp bulb mounted on AGB, displayed on MFD, increments of 1 degree c.
Summary of oil pressure indicating for fusion system.
oil pressure transducer mounted on AGB, displayed on the MFD, pressure sensed by transducer and transmitted to EDC and DCU. 0 volts = 0 psi, 5 volts = 200 psi
When will your low oil pressure annunciator illuminate.
Below 40 PSI, low oil pressure switch mounted on the AGB, displayed on CAS on the MFD.
Where is your chip light displayed?
Via the CAS system on the MFD.
What should be done to the oil system if contaminated?
Oil cooler replaced and system flushed clean.
How many gauges are there for the analog system?
12 guages stacked in 2 vertical rows of 6
Interstage Turbine Temperature (ITT) is generated by signals from the engine thermocouple over a range of
0 to 1200°C.
The interturbine temperature (T5) system consists of
positive and negative bus-bars, 10 immersion thermocouple probes, wiring harness, T1 trim thermocouple, and related parts.
What intervals are there for your over torque pressure intervals?
A. 0 to 100% (Normal).
B. 0 to 102% (Transient for 5 minutes, caution for 2 minutes, after 7 minutes Red). C. 102% to 156% (Caution for 20 seconds, after 20 seconds Red).
Two sources for all engine parameters exist for each engine, what are they?
Data concentrator unit and the Engine Data Concentrator.
