 Posted: Thu Apr 12, 2012 5:49 pm Post subject: Dynon EFIS |
 |
|
Hi Folks,
I'm still thinking of putting in the Dynon D100 EFIS with pitch and roll
autopilot for a project this winter. A couple of questions though from
anyone who has already done this - or similar.
1) does the Rotax generator generate enough power to handle the
additional power consumption of the EFIS and servos or would I need to
add more power generation via a generator presumably mounted to the
vacuum pump pad?
2) the servo installation instructions say" Wire Sizing: While it is
beyond the scope of this installation guide to advise on specific types
of wiring for a particular aircraft, choice of wiring should be sized to
1) minimize voltage drop over the length of the particular wiring run,
and 2) conduct the amount of current required by the subsystem without
the wiring becoming warm to the touch." Any ideas how to figure this out?
Regards,

Hi Martin
"without the wiring becoming warm to the touch." Any ideas how to figure this out?"
Bob from Aeroelectric has a 27 meg .pdf of advisory circular 43.13:
http://www.aeroelectric.com/Reference_Docs/Advisory_Circulars/
If you don't already have a copy, you can download and there are tables for continuous and intermittent use wire size tables. They also specify if wires are in a tight bundle or if in free air.
Also worth a download of Europas build manual CBM25 ,Ele4ctrical System:

Hi Martin,
" 1) does the Rotax generator generate enough power to handle the

vacuum pump pad? "
I am in the process of installing the Dynon Skyview which I presume has a higher current draw then the unit you are installing. Current draw for Skyview and associated systems, less the autopilot, is only 3.5 amps ( +1.5 amp current draw to charge the back up battery). Van's aircraft is planning to release the RV-12 with two Skyview displays and one back up battey all powered from the 912S stock generator. For my installation the Rotax generator is sufficient.
"2) the servo installation instructions say" Wire Sizing: While it is
beyond the scope of this installation guide to advise on specific types
of wiring for a particular aircraft, choice of wiring should be sized to
1) minimize voltage drop over the length of the particular wiring run,
and 2) conduct the amount of current required by the subsystem without
the wiring becoming warm to the touch." Any ideas how to figure this out?"
Regarding the A/P servo, I wired up the harness last night. I am using the SV32 servo (1.83 amps while engaged). Dynon sells a wiring harness for their A/P; 20 foot in length made up of (2) 20 AWG wires for powering the servo and (5) 22 AWG wires for data and a/p disconnect. For the Europa this is more than sufficient. Rather than purchase Dynon's harness (I don't need 20 foot of wire) I wired up my own using the same spec wire. Stein Air sells 7-conductor pre-twised TEFZEL autopilot servo wire with the same Dynon specifications as above for $1.45 per foot. They also carry mil spec D-sub pins and connector shells to complete the installation for a fraction of the cost of the Dynon harness.

Thanks to all who sent advice. Still in planning stages.
