Honeywell, ACSS will settle suit out of court
Honeywell and ACSS have agreed to let a private arbitrator resolve their ongoing legal dispute over EGPWS patents.

Honeywell and ACSS have agreed to let a private arbitrator resolve their ongoing legal dispute over EGPWS patents. As a result, Honeywell has dismissed its lawsuit against ACSS (filed last August in U.S. District Court in Delaware) which had accused the smaller company of infringing patents first applied in the enhanced version of Honeywell’s GPWS.

ACSS (Aviation Communication & Surveillance Systems), a joint-venture company owned by L-3 Com- munications and Thales, is close to certifying a competitor to EGPWS called T2CAS (see page 62), which combines TCAS with a terrain awareness and warning system (TAWS). The TAWS portion of the product, known as the ground collision avoidance module, was originally developed by Dassault as the terrain- following system in Mirage fighters and later purchased by Thales.
