D&D Design of West Milford, N.J., received an STC for installation of the Honeywell Mk XXII Enhanced GPWS with the latest 008 software in the Sikorsky S-76B and -C. Software 008 permits the EGPWS to continue mapping by dead reckoning if GPS reception is lost. The EGPWS lists for $48,500. With installation, the all-up cost is about $80,000. STC data packages are available from D&D for “under 3,000.” The FAA is preparing a rule to require EGPWS with 008 software on Part 135 rotorcraft starting in 2005, according to D&D.
