THE US FEDERAL Aviation Administration, is proposing that, new software be introduced for Honeywell-made airborne wind-shear detectors.
The proposed airworthiness directive (AD), which follows a US National Transportation Safety Board recommendation, would require new software which eliminates delays in the warning systems of the Honeywell standard wind-shear-detection and recovery-guidance system.
With the existing software, delays in the wind-shear-warning system may occur during takeoffs and landings, when the aircraft's wing flaps are in motion while changing position.
As many as 2,320 aircraft worldwide could be influenced by the proposed AD. Carriers would have two years from the effective date of the AD to complete the software upgrade.
