Display type EEM AM4 01 T01

This instrument presents flight and engine parameters.

The instruments include four displays. They presents parameters:

1. Display A (upper left):

  •  Air speed of the aircraft

2. Display B (upper right):

  • Altitude – in the upper left quarter of the display;
  • Vertical speed – on the right side of the display;
  • Reference pressure – in the bottom left quarter of the display;

3. Display C (bottom left):

  • Engine speed – in the upper of the display;
  • b. Cylinder head temperature – in the middle of the display; its right bar graph shows the temperature of the right side of the cylinder head, and the left bar graph – the temperature on the left of cylinder head;
  • c. Exhaust gas temperature – in the bottom of the display; its right bar graph shows the temperature measured of the right side of the engine, and the left bar graph – the temperature on the left.

4. Display D (bottom right):

  • Oil pressure – in the upper left quarter of the display;
  • Oil temperature – in the bottom lest quarter of the display;
  • Fuel- level – in the right of the display;
  • Flight time (measured from the last start of the engine) – digits in the bottom left of the display;
  • Hobbs (total engine running time) – digits in the bottom right of the display;
  • Voltage – the upper left of the display;

The casing is made of anodised aluminium. The LCD display is protected by high quality acrylic cover with anti-glare coating. This makes the device durable and easy to maintain.

The readings are displayed in both digital and graphical form. For immediate recognition of the status, colour codes are used. If the air speed stays within the desired range, the instrument displays values in green. If the warning threshold is crossed, the instrument informs the pilot by changing the colour of graphs and digits to orange. If alarm levels are reached, the digits and graph bars turn red. The threshold values (both upper and lower) are to be defined by the buyer at placing an order.
