value on the scale. The white triangle on the scale identifies zero roll.
Two short dashes identify 10 and 20 roll. Larger dash is used for 30
roll, next short dash for 45 and final longer dash for 60 .
During flight, two orange markers identify the roll required to keep
selected turn rate. Please note that turn rate marker position depend
on the airspeed and they move as speed is changed.

The pitch scale gives a rough estimate about current pitch angle. The

scale should be read at the middle point of the yellow wing reference
line.

Altitude Indicator
The altitude indicator, also known as altimeter, is used to measure the atmo-
spheric pressure from a static port outside the aircraft. This measurement is
then converted into an altitude above sea level in accordance with a mathe-
matical model defined by the ISA. The altitude is always calculated according
to some reference pressure (QNH value – baro-correction). This pressure must
be set by a pilot and can be changed during flight. The QNH value is typically
obtained from air traffic control.
The indicator shown on Figure 20 is used to display calculated altitude and
reference QNH pressure (baro-correction). The altitude is shown by two nee-
dles, where the short needle points to 1000 feet (or meters) and the long needle
points to 100 feet (meters).
A touch on the QNH window opens the QNH editing window.

Tachometer (RPM) and Manifold Pressure Indicator
A tachometer is an instrument that measures the rotation speed of a motor
shaft. It displays engine revolutions per minute (RPM), hence its alternative
name the RPM indicator. A manifold pressure is an effect of choked flow
