Notice and Warnings
Warning: Any failure to comply with the following warnings can
lead to property damage, and serious injury including death.
Although Trio Avionics has taken reasonable steps to test its product, the final determination of safe
operation lies with you, the installer and pilot. Your workmanship in installing, cabling, and testing the
Altitude Hold system in your airplane is critical to safety. If you are not the original builder of your aircraft,
and do not hold a valid “Repairman’s Certificate” for your aircraft, you must have the installation done by a
qualified A&P aircraft mechanic or the original builder. You must comply with all current FAA regulations
regarding installation of this device in your airplane.
This product is to be used on homebuilt, experimental aircraft only. It is not approved for, nor is it legal to
install it in, certified aircraft. It is not approved by any governmental or non-governmental agency.
Prior to installing or flying this altitude hold system, read the manual completely. If you have any questions
about the installation or operation of the system, STOP and then call or email Trio Avionics for clarification.
The servo that is a part of this altitude hold system is attached directly to your elevator control system. It is
possible to install or adjust it in a manner that may result in improper or unexpected elevator movement that
could result in dangerous aircraft maneuvers. Install it only after you have read and understand the
installation instructions. You must thoroughly inspect and test your installation prior to flight. Mistakes in
any modification to your aircraft can be life threatening!
Each homebuilt aircraft is individual in its construction, maintenance and flying characteristics. Therefore,
while Trio Avionics has tested the product in a variety of aircraft, we do not represent or warrant that it is
appropriate or suitable for use in your particular aircraft. Only you can make that determination and
ultimately only you are responsible for its safe installation and use.
This product is designed for use as an en route navigation aid only, and only at safe altitudes in
unobstructed airspace. It must not be relied upon for any other purpose. It is not to be used for flight in
instrument meteorological conditions (IFR), or approaches into airports in either IFR or visual (VFR)
conditions. Power to the servo must be turned “off” for takeoffs and landings.
In operation, this product relies upon data provided by solid state sensors, gyros and electronic
components. Always keep in mind that such systems should never be thought of as totally reliable. They
may be disrupted by electromagnetic interference, close proximity of transmitting antennas and cables, and
other problems.
When flying an aircraft with this, or any, altitude hold system enabled, you must be constantly vigilant for
any sign of improper operation of the system. When there is even a suspicion that the altitude hold system
is not operating properly, you must immediately disable the altitude hold system by any of the various
methods detailed in this manual. Do not fly the altitude hold system without incorporating the remote servo
disconnect switch that is described in this manual.
There may be a tendency to concentrate on the instrument display when test flying this or any other new
system in your aircraft. Do not allow it to distract you from the need to “see and avoid” other aircraft.
The safe practice of aviation demands the consistent exercise of pilot skill, knowledge of
airmanship and weather, judgment and focused attention at a level which is appropriate to the
demands of each individual situation. Pilots who do not possess or exercise the required
knowledge, skills and judgment are frequently injured or killed. Therefore, although an altitude
hold system can serve as a useful navigation aid, no altitude hold system can be relied upon and
you must be at full attention at all times while flying any aircraft.
If you do not agree to comply with any of the warnings or notices above, do not
install or fly this altitude hold system in your aircraft. Call Trio Avionics for a
Return Material Authorization (RMA) and return the unused system for a full
refund.
