FAA has given the green light to 32 helicopter wide area augmentation system (WAAS) lateral precision with vertical guidance (LPV) instrument flight procedures from Orange Beach, Ala.-based Hickok & Associates. The new flight procedures provide descent altitudes between 250 and 300 feet, instead of the current lateral navigation (LNAV) minimum descent altitudes (MDA) of 460 to 500 feet. Hickok is currently developing 33 additional LNAV procedures. The company is also maintaining 28 flight procedures previously held by FAA. The WAAS LPV program holds supplemental type certificates (STCs) for the AgustaWestland AW109, Bell 429, Eurocopter EC135 and EC145, and Sikorsky S-76.
