Engine Flashcards
How many Oil Sumps are there and How many Bearings
SUMP A = Bearings 1,2,3
SUMP B = Bearing 4
SUMP C = Bearing 5
What is on AGB
Fuel EDP, IDG, ATS, Hydraulic EDP, Lube & Scavenge, Chip Detector
What does the Oil System lubricate
AGB and 5 Bearings
What is Vx and Vy
Vx = Green Dot Vy = Green Dot + 50kts
What are Thrust Reversers Lockouts used for
They are Red and used to denote a MEL’d TR
What does a Cyan Line on the N1 gauge represent during Approach and when does it appear
Min N1 to meet Bleed Requirements and will appear when configured for Landing < 1200’ RA when A/I is ON
What within FADEC provides the Under - Overspeed Protection and at what %
FMU in the FADEC 52% (Underspeed) and 102% (Overspeed) N2
What 4 Scenarios does the ATTCS command RSV Power Automatic
Automatic: 15% Difference of N1 values OEI T/O OEI G/A Windshear
Manual:
Thrust Levers to Max detent
Which IDLEs increase Min N1 due to Ice speeds
FLT IDLE & APPROACH IDLE for Bleed Protection
What is Max Oil qty AMS Usable Oil qty
Max = 10.5 qts Usable = 7.5 qts
What does a Cyan OFF on the N1 EICAS indication indicate
Cyan OFF indication is displayed when the Engine is shutdown in FLT by Pilot action
What are 2 Major Components of the Starter System
Starter Control Valve (SCV) and Air Turbine Starter (ATS)
What is the purpose of the SCV
Opens to allow Bleed Air from APU, Cross side Engine or GRD source to Power the ATS
Describe N2 Spool
10 Stage Axial Flow Compressor with a 2 Stage High Pressure Turbine
Describe the Variable Geometry Actuators
2 VGA’s per Engine, master/slave configuration, Fuel Pressure driven that control Compressor Stator Vanes Stage 1 - 4
