STATIC PORT SWITCH
There are two static ports (to measure static pressure) on the AKS 21 Mi. One total energy
compensated (TE) mounted on the Vertical stabilizer and the others are little holes in the fuselage
(Stat). The Static Port switches the source of the variometers between these ports and is marked
with glider and motor operation.
When you use the engine you need to select the static port in the fuselage to get a correct reading
of the variometers and prevent failures.
SPEED TO FLY SWITCH
The variometer has a ‘speed to fly function’. It is based on MCReady Theory and tells you at which
speed you fly most efficient calculated using the current sink and the expected climb in the next
thermal. When you switch it to speed to fly (Vario), the vario shows you if you need to fly faster or
slower (also the audible one).
ENGINE CONTROL GAUGE
The engine control gauge provides feedback on the engine (temperature and RPM) and
is used to starts and stop the engine and to extend and retract the propeller. Complete
functionality is explained in the flight manuals.
