    Power Up NOTE: When powering up the autopilot ensure that the aircraft is as still as possible for 10 seconds. The power up of the autopilot takes approximately ten seconds. During the power cycle it is very important that the aircraft be as still as possible for the initialization of the internal gyro.
  • Page 4: Mechanical Considerations

Improper servo installation or failure to observe and diagnose installation problems prior to flight can result in extremely serious consequences, including loss of ability to control the aircraft.

    disturbance. Shielding has no effect on this problem; the only solution is to keep strobe light wiring as far away as possible from any electronics which can be affected by pulsating magnetic fields. RFI/EMI considerations The autopilot programmer is shielded and does not generate any appreciable level of electromagnetic interference. Moreover, the servo lines (except for power and ground) are low-current and cannot contribute to RF interference.
