Altrak VS control panel installation
The Altrak VS comes with a reversible control panel, which can be mounted either horizontally or vertically.
The engage/disengage button requires a 5/8” diameter hole; the same size hole can be used for the mounting
of the VS control knob. A template for the two holes is included with this manual. When putting the knob on
the VS control potentiometer, the pointer must be pointing at the larger white mark on the control panel. This
is shown below for both the horizontal and vertical mounting orientations.
Power Up
When powering up the autopilot ensure that the aircraft is still
for 10 seconds.
The power up of the autopilot takes approximately ten seconds. During the power up cycle it is very
important that the aircraft be as still as possible for the initialization of the internal gyro. While the
autopilot is in the power up phase, the enunciator will flash rapidly for approximately ten seconds. Once the
power up phase is completed, the enunciator will remain unlit.
