| SA4550 Primary Attitude Display |
The new SA4550 Primary Attitude Display is the perfect update for aging Sperry and Collins electromechanical ADIs. Providing reliable, easy-to-read attitude information, the SA4550 accepts input from existing sensors to provide a clear, reliable depiction of the aircraft's attitude in pitch and roll. And because it features Sandel's patented bright, high-contrast display -- the same technology used in the latest military aircraft -- you get unmatched readability in any lighting, while eliminating the high maintenance costs and potential for failure associated with older electromechanical units.
Standard ADI features include flight director command bars and a glideslope/localizer deviation scale; convenience features include a fast/slow indicator and mode annunciations to make flying easier and safer. A pilot-selectable single-cue/split-cue display option is also available. |

Featuring an ultra-wide viewing angle (180 degrees in both the horizontal and vertical axes), the SA4550 boasts an MTBF in excess of 10,000 hours. With Sandel’s
patented LED display technology generating a resolution
of 200 pixels per inch — unmatched in the industry
for brightness, clarity, readability and color fidelity — you’ll
find the SA4550 completely transforms your panel. Reliable, affordable and backed by Sandel’s award-
winning product support, the SA4550 is ideal for corporate
and air transport aircraft. |
