Dynon

Happy New Year all!

1. I am installing two Dynon units D100 and a D10A, the 10A as a back up. What I need to know is where is the best place to install the remote compass so as not give false readings.

2. Is it required (By a DAR) to have a wet "round" compass if I have a remote compass.

Thanks,

Remote compass

Adam, I mounted mine well behind the baggage compartment bulkhead on the bulkhead behind, away from everything. It is very sensitive, and anything metal put in the baggage compartment will affect it if it is too close. Note that it has to be mounted at the same angle as the Dynon unit (8.5 degree panel tilt) and level laterally.

As far as a wet compass and other things required this is from FAR part 91.205 (it doesn't say anything about it having to be a "wet" compass, just magnetic):

? 91.205 Powered civil aircraft with
standard category U.S. airworthiness
certificates: Instrument and
equipment requirements.
(a) General. Except as provided in
paragraphs (c)(3) and (e) of this section,
no person may operate a powered civil
aircraft with a standard category U.S.
airworthiness certificate in any operation
described in paragraphs (b)
through (f) of this section unless that
aircraft contains the instruments and
equipment specified in those paragraphs
(or FAA-approved equivalents)
for that type of operation, and those
instruments and items of equipment
are in operable condition.
(b) Visual-flight rules (day). For VFR
flight during the day, the following instruments
and equipment are required:
(1) Airspeed indicator.
(2) Altimeter.
(3) Magnetic direction indicator.
(4) Tachometer for each engine.
(5) Oil pressure gauge for each engine
using pressure system.
(6) Temperature gauge for each liquid-
cooled engine.
(7) Oil temperature gauge for each
air-cooled engine.
(8) Manifold pressure gauge for each
altitude engine.
(9) Fuel gauge indicating the quantity
of fuel in each tank.
(10) Landing gear position indicator,
if the aircraft has a retractable landing
gear.
(11) For small civil airplanes certificated
after March 11, 1996, in accordance
with part 23 of this chapter, an
approved aviation red or aviation white
anticollision light system. In the event
of failure of any light of the anticollision
light system, operation of the
aircraft may continue to a location
where repairs or replacement can be
made.
(12) If the aircraft is operated for hire
over water and beyond power-off gliding
distance from shore, approved flotation
gear readily available to each
occupant and at least one pyrotechnic
signaling device. As used in this section,
??shore?? means that area of the
land adjacent to the water which is
above the high water mark and excludes
land areas which are intermittently
under water.
(13) An approved safety belt with an
approved metal-to-metal latching device
for each occupant 2 years of age or
older.
(14) For small civil airplanes manufactured
after July 18, 1978, an approved
shoulder harness for each front
seat. The shoulder harness must be designed
to protect the occupant from serious
head injury when the occupant
experiences the ultimate inertia forces
specified in ? 23.561(b)(2) of this chapter.

Adam,
Check with your DAR about the "wet compass". There are still a few sticklers out there that want to see a wet compass. The way the rule is written, a wet compass is not required. The rule simply states that you must have a "magnetic direction indicator." The Dynon compass qualifies with the letter of the law.
