[SatNews] Cobham’s Electronic Flight Instrument System (EFIS) has received.....

.....Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) amendments for hundreds of aircraft to provide Localizer Precision with Vertical Navigation (LPV) approach capability.  LPV approaches are a part of the FAA’s NextGen air traffic system and provide precision instrument approaches equivalent to Instrument Landing System (ILS) at thousands of airports across the nation without the need for expensive ground infrastructure at each airport. The amendments cover both larger-model aircraft noted on the Part 23 Approved Model List (AML) under STC #SA02254AK and the Citation 501 under STC #SA02220AK.  Hardware and software required for LPV capability on these aircraft include the following:

• A WAAS Beta III GPS receiver
• Cobham version 7.0E operating system software
• Analog Interface Unit-2, if Cobham’s EFIS is driving an analog autopilot system

LPV is a type of approach based on the Wide Area Augmentation System (WAAS), published on RNAV (GPS) approach charts. This procedure takes advantage of the precise vertical and lateral guidance available from WAAS.
