INSTALLATION__________________________________
Is the Lifesaver approved as a primary attitude indicator?
The Lifesaver is certified as either a primary or backup attitude indicator. It can be placed in the pilot's or co-pilot's instrument panel, or used in both positions.
For more information, please see
AC20.41
which addresses installing a TSO'd instrument with a TSO'd replacement.
What certification(s) has the Attitude Indicator received?
The Lifesaver has FAA approval under TSO-C4c and is certified to
RTCA/ DO-160D.
What types of aircraft will the Lifesaver work in?
The Lifesaver is original equipment for many OEMs and has been tested in all types of aircraft, from singles to light jets, and helicopters. The Lifesaver can be installed in high-speed general aviation aircraft that fly up to 525 knots.
Will this replace my old attitude indicator?
Yes, the Lifesaver uses a 4-pin connector found standard on the majority of electric DC operated AIM and RC Allen gyros. Pin wiring may vary, so check aircraft wiring before installation. We offer units that can connect directly to many existing installations with no rewiring required. We even supply a free connector with each unit.
What size circuit breaker is needed to install the Lifesaver?
A circuit breaker needs to be 1 amp for 28 VDC and 2 amps for 14 VDC.
What size panel cutout is required?
Rear mount in standard 3 1/8" round panel cutout or front mount in ARINC style cutout. You should ensure the available instrument panel cutout meets the requirements of the Attitude Indicator. Instrument panel cutout dimensions are available in the install manual.
What approval is necessary to install the Lifesaver?
The Lifesaver is approved under FAA TSO C4c. So, if you install the unit in place of another TSO C4c unit -- where there are no changes to the form, fit, or function in the aircraft -- you are not required to notify the FAA (see FAA AC20-41A). However, if there are other changes required in the aircraft or if the aircraft is operated for commercial operations, the local FAA may require a FAA 337 and/or a Field Approval. Check with your local FAA before installation for their requirements.
The label on the unit does not specify which pin is positive and which pin is negative, how do I hook up the lights?
When hooking up the lights, it does not matter which pin you select as positive and which pin you select as negative.
What is the overall length of the unit with the battery pack?
The overall length of the unit is approximately 8 1/4 inches.
What wrench is needed in order to remove/re-tighten the pull to cage knob?
A six fluted spline wrench, .060 size.
