WAAS LPV Approvals Picking Up

 - January 5, 2009, 5:59 AM

A number of WAAS LPV (lateral precision with vertical guidance) equipment approvals for business jets have been completed recently or will be finished soon as avionics manufacturers, installation centers and operators get serious about gaining the needed certifications to fly the GPS-based procedures. Rockwell Collins last month said it secured approval for the WAAS LPV upgrade in the Challenger 604 model as part of a contract with the FAA’s Aviation Systems Standard Division. The certification clears a path for all Challenger 604 operators to upgrade to a new LPV-capable FMS from Collins. Universal Avionics, meanwhile, announced certification for its UNS-1Fw WAAS LPV-compatible FMS in the Learjet 60 in a joint effort with STC holder Haggan Aviation of Englewood, Colo. In the coming months, Duncan Aviation in Lincoln, Neb., plans to certify LPV in six business jets. These include two Learjet 45s carrying the Universal UNS-1Ew FMS; two Gulfstream G100s, also with the UNS-1Ew FMS; a Cessna Citation Ultra with a single UNS-1Espw FMS; and a Falcon 900 with Honeywell’s NZ-2000 FMS upgraded with Version 6.1 software. WAAS LPV approaches use GPS to provide landing minimums similar to those of ILS, but upgrading Part 25 airplanes to the satnav capability requires an STC.
