Avionics System Integration Flashcards
What is the mission computer?
The mission computer is the central component of the avionics system. Flight critical elements of the avionics system are designed to be independent of the single MC.
How does it work broadly?
It coordinates inputs from the avionics system and sends video for display on the MFDs.
It also sends information to the HUD system and the PFD.
The MC is controlled through the UFCP, the MDF and the HOTAS.
What is included in the MC?
One main processor, two graphics processor cards and one radar processor card.
How is it supplied with power?
By selecting the mission switch to MC or MC/HUD connects the MISSION BUS to the BATT BUS and energizes the MC and the subsystems.
What are the MC functions?
- Tactical navigation and operational training
- Enhanced engine indicating and crew alerting system (EICAS)
- Systems displays and monitoring
- Electronic checklists
- Mission data recording
What other functions does the MC provide?
- UHF-VHF radio
- ATC transponder
- VOR and ILS receivers
- DME transceivers
- TACAN
- AGs
- Aural Warnings
- Intercom volume
What front cockpit controls, indicators and displays are entirely or partially depends on the MC?
- HUD and HUDR
- UFCPs
- MFDs
- Decouple panels
- Arm panel
What are RIOCS and how many are there?
- Remote-input-output-concentrators
- 4 of them
What are the RIOC functions and interfaces?
They gather discrete, analogue and data bus signals from other systems and components in the aircraft, concentrate the data, perform control and monitoring logic and pass it on to the MC and to each other.
What are the PFD and SFD?
- Flight instrumentation displays are shown on one PFD, mounted centrally in each cockpit.
- Backup data is provided by the SFC in the front cockpit and also shown on the SFDR in the rear cockpit.
- The PFD uses the SFD data for an attitude comparator function.
- The front and rear PFDs and the SFC and SFDR always operate in tandem.
The following systems supply critical data to the PFD?
- MC
- ADC
- IRS
- FMS
- VOR 1 and ILS 1 receiver
- VOR 2 and ILS 2 receiver
- TACAN and DME transceiver
- Radar altimeter
- RIOC 2
The SFD has an integral attitude source and the following systems supply data for other SFD indications
- Air data from the ADU
- Heading data from the MHS
What does the HUD system comprise of?
- HUD PDU (front cockpit)
- HUDR (rear cockpit)
- HSG
What are the multi function displays and how many are there?
- The MFDs provide the primary display of all mission data and control input to the MC through pilot-operated soft keys on the MFD bezels.
- There are two multi function displays, one on either side of the PFD.

What radio navigation aids are fitted?
- VOR 1 and ILS 1 receiver
- VOR 2 and ILS 2 receiver
- TACAN and DME transceiver
How are the radio navigation aids controlled for primary and secondary?
Primary control is by the MC through the UFCPs
Secondary control is available through the FMS units.
What is the FMS navigation?
- The FMS provides RNAV in accordance with the requirements of standard civil IFR.
- Subject to receiving acceptable navigation information, the FMS provides RNP capability in enroute, terminal, approach and departure phases of flight.
