Aspen has shown that the EFD1000 E5 system is capable of transmitting altitude data
reliably on a better than 95% probability basis. Therefore, when the EFD1000 E5 altimeter
system is tested and calibrated in accordance with 14CFR 91.413, the EFD1000 E5 system
can be used as an Encoding Altitude source.
The EFD1000 E5 provides this output in RS-232 Format Z. See Figure 9-28 for wiring
connections.

Flush or Recess Mounting the EFD
If there is insufficient clearance between an EFD and the control column when the flight
controls are in the full nose down position, it will be required to flush mount or recess
mount the EFD in the instrument panel. Also the installer may choose to flush mount the
EFD for cosmetic reasons.
Aspen Avionics Flush Mount Kit
Aspen Avionics offers a specific Flush Mount Kit for this purpose.
Locally Fabricated Brackets
If the installer chooses to fabricate their own brackets for flush mounting the displays
then this modification is beyond the scope of this manual and will require that the
brackets and the instrument panel modification be separately approved.
