• Temperature:

• Critical: Temperature > 200°C

• Warning: Temperature < 70°C or Temperature > 180°C

• Fuel Pressure

• Nominal value is 2.5 bar

• Critical: Fuel pressure <1.5 bar or Fuel Pressure > 3.5 bar

• Warning: Fuel pressure < 2.0 bar or Fuel Pressure > 3.0 bar

On the right half of the window, by order, following information is found:

• Engine Status. Possible status are:

• STOPPED: Engine is not working. The word STOPPED will be red coloured and

this state is linked to a critical alarm in the ENG alarm in the alarms panel.

• CRANKING: Engine is being externally turned. Word will be black-coloured and

this state is linked to warning state of the ENG alarm in the alarms panel.

• WARMING-UP: Engine has been recently started and it is running an

automatic warm-up cycle. During this time, the autopilot does not have

control over engine RPM and the engine is not ready for flight. This mode will

end as soon the mean of both engine temperature indication reaches 80 °C.

When in this state, the word WARMING-UP will be coloured in orange and this

state is linked to a warning state of the ENG alarm in the alarms panel.

• RUNNING: Engine is running by its own means and the autopilot has control

over it. In this state, the work RUNNING will be green coloured and, if no

other problem is found in the engine operating parameters, this is linked to a

normal state of the ENG alarm in the alarms panel.

• ECU working condition information: temperature and main voltage value.

• Control information: Values the control is trying to maintain. These values and the

measured values should agree.

• Alarms: This subpanel holds the alarms information regarding engine subsystems.

Any abnormal condition will be signalled by showing the word FAIL coloured in red

and it will trigger a critical alarm state of the alarm ENG in the alarms panel.

Vibration frequency Graphs

Accessed through View → Vibration Frequency Graphs, this unique functionality allows you

to examine the vibration spectra of your vehicle in real time. With this tool you can clearly

see the source of vibration in your system and check if the system vibration is nominal, or,

on the other hand, there is a new source of vibration indicative of a failure.

In this window you can see the current state of the three axis vibration pattern, with a bar

that scans the different frequencies. On the right hand of every axis you have options to

alter the vertical scale (x2, x1, x1/2, x1/4) that will alter the height of a given vibration

amplitude.

Also, there is a checkbox titled “LPF”

: with it checked you will see the mean of various

samples and unchecked will give the immediate result.

17 LPF stands for Low Pass Filter
