DFC90 STC for Bonanzas Granted today

The table below lists the Bonanza models covered by this STC. Both 14V and 28V aircraft are covered.

The DFC90 is plug and play with the STec 55X (meaning just the control head needs to be replaced and all other elements can remain untouched). It is also approved to replace the STec 30/50/55/60-2/65 but obviously the control head is not just plug-and-play in that case.

The install also requires the presence of an Aspen PFD (EFD1000) with v2.6 or later software.

Wiring in the flap position switch is optional. Doing so adds the "Flap Overspeed" aural alert and improves the accuracy of the full-time Envelope Alerting underspeed alert (stall speed changes with flap position). The STC allows for installations with and without the flap wiring.
