Avionics Exam Questions with Correct Answers (Grade A+)
Question 1: Define Fixation (regarding PFD)
Answer: Psychological condition, pilot focuses on one thing.
Question 2: Turn coordinator, how is that presented on the PFD?
Answer: It is a segmented triangle, bottom half slides (ball).
Question 3: How do you know when you are in flap operating range (PFD)?
Answer: The white colour stripes/ Line beside the airspeed line.
Question 4: AHARs system senses movement on which axis of the aircraft?
Answer: Measures movement along the lateral, longitudinal, and normal axis.
Question 5: How is an unusual attitude depicted on PFD?
Answer: The Chevrons, Red arrows that tell you where to go.
Question 6: assuming the failure of the ADC, what instruments will be inoperative?
Answer: Loss of Pitot static: VSI, Airspeed indicator, and Altitude indicator.
Question 7: How are failures of instruments represented?
Answer: Big red X
Question 8: What is the big advantage of WAAS?
Answer: Provides enhancement to GPS signals, monitors satellites and if on or more get out of sync it will
try to correct it.
Question 9: how does WAAS operate?
Answer: Ground to satellite to masterstation to satellite to plane.
Question 10: What is RNAV and what does it allow us to do?
Answer: Area navigation, allows pilot to navigate from point to point, latitude and longitude.

, Question 11: How many meters of accuracy does WAAS provide?
Answer: at least 7 Meters of accuracy both vertically and horizontal.
Question 12: Define mode awareness
Answer: Pilots ability to keep track/ and monitor systems
Question 13: difference between Flyby and flyover waypoint images.
Answer:
Question 14: Why would you need two different types of waypoints (flyby and flyover)?
Answer: In case of terrain
Question 15: What sensitivity does the GPS maintain in enroute mode?
Answer: 5 NM
Question 16: RAIM, does it do it automatically or force it or can you do both?
Answer: Receiver Autonomous Integrity Monitoring: You can do Both, but usually does it on its own
Question 17: How many satellites need to be in view for reliability for instrument nav systems?
Answer: 5 satellites for IFR
Question 18: Cruising along at 8000ft, you are asked to cross London VOR at 3000ft, planned decent
speed of 100 knots, however you end up flying at 110knots, where will you be regarding the decent
path?
Answer: You will be above the decent path, because your ground speed is faster so you are ahead of the
path.
