NPRM Looks at Enhanced Vision System Flexibility

The FAA is seeking responses to a notice of proposed rulemaking (NPRM) that it believes will significantly improve operational flexibility for operators using an enhanced flight vision system (EFVS). Comments on FAA-2013-0485 are due by September 9.

Currently, Part 91 EFVS-equipped aircraft may take advantage of lower landing minimums by allowing pilots to substitute an electronic image of the runway for their natural vision. With the electronic version of the runway environment in sight, aircraft may descend to 100 feet above the minimum descent altitude or touchdown zone elevation while conducting an instrument approach.

The new proposal, which sets new training and currency standards for pilots, will also add the possibility of landing when touchdown or rollout runway visual ranges fall as low as 1,000 feet. Under the proposal only pilots who have flown at least six EFVS-supported approaches in the previous six months would be allowed to take advantage of all available landing options. Additionally, the NPRM would allow specific operators to dispatch aircraft when destination airport weather is below standard visibility minimums and also begin an instrument approach.
