Heading Indicator with Moving Map
Figure 55:
The combination of rotor RPM and engine RPM. Both scales are in percentages.
Like in the gyrocopter case, the bottom window can be configured to show the manifold
pressure.
Both scales are fully configurable.
The optional green range defines the recommended range of RPM.
The optional yellow range defines the range of RPM, which should not be used for
longer period and should be generally avoided.
The red lines limit the RPMs.

Heading Indicator with Moving Map
Nesis introduces a combination of heading indicator and moving map. Traditionally, a head-
ing indicator
28
informs a pilot about the airplane heading. However, in Nesis a pilot can
choose between true
29
heading, tracking and magnetic heading. This selection was described
in section 6.3 on page 36.
The scale and the map is rotated in the direction of the airplane nose.
The tracking option is based on the movement of the airplane. In this case the scale
and map are orientated in the direction of the airplane ground track. The tracking
information is based on the GPS tracking.
The magnetic heading option displays the map in the magnetic direction detected by
magnetic compass.
Figure 56 shows that the indicator is equipped with a lot of useful information:
The direction box shows numeric information of current true heading.

Heading indicator is also known as directional gyro.

The Magu unit has a built-in world magnetic model, which provides magnetic worldwide declination and
inclination information. Hence the magnetic heading is automatically corrected into true heading. Note
however, that the precision of the model is limited to general magnetic field behavior. The model does
not include large local anomalies and unpredictable events like magnetic storms.

We will use the term heading to describe the instrument. However, if tracking option is active it should
read tracking instead.
