Sandel SA4550 Primary Attitude Display
	 
	The new SA4550 Primary Attitude Display upgrades electromechanical ADIs to an LED-backlit display with pilot configurable single or dual-cue flight director command bars, 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.. Plug compatible with various Sperry, Collins and King indicators for ease of installation. 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.
