The EMSIS AHRS is a 80 mm (3⅛”) instrument
and is the central part of the LX instrument system;
it and the other instruments turn on immediately
after main power is applied.
The display is divided into three parts, the upper
part displays your track heading (derived from
inbuilt GPS) the larger middle section is an artificial
horizon indicator and the lower part shows IAS,
altitude and QNH.
QNH always matches the value which is set on the
altimeter. The altimeter has the QNH adjustment
knob which is shared between both instruments.
