Avidyne | DFC90, 100 FAQs (Last updated: 26 June 2012)

(DFC90) What does a typical DFC90 installation in an Aspen-equipped Cirrus

involve? The upgrade to the DFC90 is a two-part upgrade – the Aspen PFD must be

updated in order to communicate with the DFC90 . The second part of the DFC90

upgrade is to replace the STec flight control computer with the Avidyne DFC90 flight

control computer. This is just a matter of having the autopilot flight control computers

swapped and some flap wiring added. In most cases, the original autopilot tray and

wiring is left intact/untouched. (added 24 July 2011)

(DFC90) What does a typical DFC90 installation in an Aspen-equipped Baron,

Bonanza or Skylane involve? We have not yet compiled any installation time

estimates but generally speaking, the following tasks will need to be accomplished:

• Remove all the legacy gear, if not already done so by the Aspen mod (e.g. ADI,

HSI, Remote Annunciators, Mode controllers, DGs, Alt/VS Preselectors, etc);

• Replace the autopilot tray (except for S-TEC 55/55X installations where the tray

is reusable);

• Install the new equipment (e.g. DFC90 autopilot tray if required, DFC90 flight

computer, etc)

• Install the autopilot harness adaptor (expected to be a plug & play adapter harness

that uses the existing autopilot wires/connectors/harness for most airplanes but

others will be easier to replace unreliable or poor existing connectors/harnesses

with a new one). Note that when replacing an STec 55X, there is no harness

adapter required;

• For aircraft that are replacing a King autopilot with the DFC90, the King servos

must be swapped out for the new Avidyne ASA575 servos which are a form-fit

replacement for the King servos;Add any supplementary wiring required (e.g.

wiring in the flap position)

• System checkout and paperwork signoff
