Sandel Avionics is adding new WAAS approach annunciations to its 4-ATI electronic primary navigation display, the SN4500, with a software update available next month. The Vista, Calif. manufacturer of plug-and-play EFIS replacements for legacy electromechanical attitude-director and horizontal situation indicators said the SN4500 will then annunciate the type of WAAS approach that is armed.

Annunciations include LPV (lateral precision, vertical guidance), LP (lateral precision), LVnav (lateral navigation with vertical guidance) and Lnav (lateral navigation ) in addition to the display of GPS/WAAS lateral and vertical deviation with GPS integrity monitoring annunciation already on the SN4500.
