PILOT’S GUIDE Current and future solutions are considering multiple stages of flight, such as approach to land, taxi and reduced take-off operations during low-visibility conditions. This is in addition to other benefits that the various vision sensors can and do provide. Below are a series of charts showing the various technologies and how they provide for different credits. A credit is a specific operational benefit derived from the application of the FAA airworthiness circulars and certification effort. Table 2: Below is the current and future status of credits in each aircraft operations category. Operation* PART 91 PART 91K or 135 PART 121 Lower landing limits Yes Yes Yes Lower take-off limits NA Yes Yes Approach ban clearance NA Yes Yes Surface movement ops NA RTCA RTCA * In EU Ops, the same flight rules apply for all three different categories of aircraft. NA – not applicable. RTCA – refers to being “in work” by RTCA SC213 special committee. Part 91K, 135 and 121 approvals are typically issued to specific operators via special authorization and OpSpecs. Table 3: Below is the technology combination driving the credit (current and future).

The FAA currently uses the term enhanced flight vision system, or EFVS, when an EVS is displayed on a HUD and certified for operational credit. Continued on following page… - 27 -
