EASA has certified a new altitude monitoring function on Airbus A320-series airliners, according to NAVBLUE, Airbus’ flight operations and air traffic management subsidiary.

The altimeter setting monitor, an element of the Honeywell SmartLanding system, cross-checks GPS altitude against barometric corrected altitude and issues an alert to pilots if a barometric reference setting error is detected. It is the first of three functions of a landing surveillance suite NAVBLUE is developing to complement the Airbus Runway Overrun Protection System (ROPS).

NAVBLUE, Airbus, Honeywell and Lufthansa Group are working together on development and certification of the new functionalities.

An approach stabilization monitor to check for excessive height and/or speed deviations on approach and a taxiway landing monitor to warn pilots if an aircraft is not lined up with a runway below a certain altitude will be certified in the next software release, NAVBLUE said April 17.

ROPS continuously monitors an aircraft’s position with respect to the remaining runway length and calculates whether the aircraft can safely come to a stop. Honeywell’s SmartLanding system is a software upgrade to the company’s Enhanced Ground Proximity Warning System.

“We are delighted to introduce the first part of the landing surveillance trio, which will offer our customers an additional innovative product to complement ROPS,” NAVBLUE VP-onboard systems Pierre Madrange said. ROPS “has already performed over three million safe landings and is trusted by over 90 operators worldwide,” he said.
