AOC IQT TEST 1 FINAL STUDY PAPER 2026
COMPLETE QUESTIONS AND ANSWERS
◉ If DEEC health is good, what will the system report? Answer:
"Good" = good / "Bad" = Bad
◉ How Many Pitot tubes are there and where are they located?
Answer: 3 total Pitot tubes. 1 under the right wing, 2 under the left
wing.
◉ How many static ports are there and how are they arranged?
Answer: 6 total, 3 sets of 2
◉ What kind of navigation does the EGI use? Answer: Hybrid:
Combination of INS between GPS updates
◉ At what rate does INS accuracy degrade during GPS failure?
Answer: 0.8 nm per hour
◉ What are the 5 main components that provide data streams to the
ADCS? Answer: Pitot tubes: Primarily provides the Airspeed
datastream.
Static ports: Primarily provides the Altitude datastream.
,EGI: Primarily provides the Attitude and Navigation datastream.
Alpha probe: Provides the AOA.
Laser Altimeter: Only used within 100ft of the ground
◉ How is air pressure from the Pitot tubes and Static ports
converted to electrical signals? Answer: PPT: Precision Pressure
Transducers
◉ What are the 6 components that make up the ADCS itself?
Answer: CCDL
Fault tolerant components
FCA's
RCM (Brains of the Aircraft)
UARB
Vote Processors
◉ Data from each aircraft navigation and data system component
(EGIs and PPTs) is sent to their respective _____ that is located on the
RCM. Answer: FCA
◉ How do FCA's share information with each other? Answer: CCDL
, ◉ What component carries the commands from the RCM to the
servos? Answer: Two UARB buses (A and B)
◉ Where does mid-level voting take place? Answer: FCA's
◉ What happens when 1 or 2 of the sensors fail in regards to mid
level voting? Answer: 1. If one sensor fails (bird strike, ice, etc.) then
mid-level voting still takes place and the faulty valve is still factored
into selecting the middle value.
2. Once two sensors fail, mid-level voting ceases and data from one is
utilized
◉ What is the Function of the Vote Processors? Answer: Take the
FCA outputs and based on results chooses information from one and
selects that FCA as the FCA in command
◉ When in contact with both Ku and LOS signals which will be
prioritized? Answer: LOS
◉ What links are used in LOS/Ku? Answer: LOS: Uplink and
Downlink
Ku: Command Link and Return Link
