ACTUAL Exam Questions and CORRECT
Answers
Wide Area Augmentation System - CORRECT ANSWER - WAAS
Higher accuracy and reliability
Augmented by ground stations: provide GPS position corrections
Reference and master stations
Ground station received signal from satellite - compares signal to known position and figures out
position difference
FDE
Check Status: GPS NOTAMS and WAAS page (specifically request them from flight briefer)
Global Positioning System - CORRECT ANSWER - 31 satellites
Orbiting earth
two orbits every 24 hours
Transmit signal to GPS receivers (continuously)
Receivers calculate distance to satellite by measuring the time differences (signal sent from
satellite until received by receiver multiplied by speed of light)
4 satellites needed to correct for time errors in receiver
Altitude and position
No VOR limitations
Legacy navigation system - CORRECT ANSWER - VOR - serve small areas: service
volumes
limitations due to line of sight reception and power output: limits range
Area Navigation - CORRECT ANSWER - RNAV: allows you to plan and fly optimum
route at efficient altitude
,Not limited by service volumes of ground based aids
-GPS: need IFR approved
-Intertial Nav Systems (INS) oceanic routes
-DME
High end systems grouped into RNP categories-require specific nav equipment, training and
authorization
Approved IFR GPS - CORRECT ANSWER - Must be panel mounted
Installation approved by FAA
Flight Manual Supplement - approved
No kneeboard or yoke mounted handheld GPS: aid to situational awareness ONLY - not primary
Localizer performance with vertical guide - CORRECT ANSWER - LPV
Sensitivity is angular
2 degrees
non-precision approach
requires WAAS capable GPS
Non WAAS systems - CORRECT ANSWER - Validated using RAIM
unaugmented GPS
Not using groundstations corrected position signal
Certified under different TSO
Not standalone
Must have avionic for ground-based navigation facilities: must be operational - VOR, DME, or
ADF
Need to check additional NOTAMs for ground based
Receiver Autonomous Integrity Monitoring - CORRECT ANSWER - RAIM
, If fails, cannot rely on GPS for accurate info
Monitors at least five satellites
Can be augmented with barometric altitude
Near 100% availability of oceanic, en route, and terminal phases
Better coverage required for approaches
If you see INTEG message: go Missed
Fault Detection and Exclusion - CORRECT ANSWER - FDE
In WAAS GPS systems
6 satellite in view to detect a faulty satellite
Excludes bad satellite from position solution
RNAV 1 - CORRECT ANSWER - System needs to be accurate to 1 NM, 95% of the time
RNAV 2 - CORRECT ANSWER - System needs to be accurate to 2 NM 95% of the time
Technically Advanced Aircraft - CORRECT ANSWER - TAA
PFD
MFD with moving map using GPS and showing aircraft position
Integrated two-axis autopilot system
Limitations:
Hazards: Complacency, over reliance, environmental conditions
Engine Indication System - CORRECT ANSWER - EIS
On MFD
RPM
Manifold Pressure
Fuel
