All MFD can present all info pages by crew choice
What does amber graphics on VMD mean?
BIT Problem…
How do you switch on/off DKU?
With button in upper left corner of DKU
What is another word for ‘Volumes’ when talking about DKU/MFD:s?
Main System…
How do you switch from ‘maintenance mode’ back to ‘operational mode’?
Need to Power down H/C and on again (wait always at least 15 s)
When switching Battery Power on, what happens with DKU:s?
Left DKU(1) will show a rainbow pattern for a minute during PBIT, then picture. DKU(2) will be black until AC comes on.

Last input
What are the three 1553 bus systems?
Core bus, Mission bus (1), and Mission bus (2)
Core bus is for basic avionic and flying, Mission bus (1) is for mainly sensor, advanced navigation, displaying and recording purposes, and Mission bus (2) or NAVAL is for SONAR, RADAR, EWS, Tactical COM with operators.
What is the purpose of the Core bus?
The Core bus is used for basic avionic and flying.
What is the purpose of Mission bus (1)?
Mission bus (1) is used mainly for sensor, advanced navigation, displaying, and recording purposes.
What is the purpose of Mission bus (2) or NAVAL?
Mission bus (2) or NAVAL is used for SONAR, RADAR, EWS, and Tactical COM with operators.

What does the oil minimum level detection (LEVELMIN) in the hydraulic circuit 1 lead to?
The tailrotor Shut Off Valve closing.
The electrically driven hydraulic pump is energized thanks to?
115V/400Hz AC
What occurs if there is a hydraulic system 2 minimum level detection (LEVELMIN)?
Main rotor and tail rotor actuators remain powered and the utility circuit is lost.
When there is a low pressure detection on the Flight Control hydraulic circuit 1, selecting the Flight Control 2 Shut Off Valve switch to OFF position?
The Hydraulic Circuit 2 remains pressurized.
Each hydraulic pump is connected to?
One pressure line, one suction line and one case drain line.
In case of an overheat detection on the hydraulic circuit 1?
The whole circuit has to be isolated thanks to the Shut Off Valve 1 switch.
What is the type of pumps belonging to the hydraulic system?
Axial piston pumps
