Enhanced Flight Vision System (EFVS)

Definitions

• An installed aircraft system which uses an electronic means to provide a display of the forward external scene topography (the natural or manmade features of a place or region especially in a way to show their relative positions and elevation) through the use of imaging sensors, including but not limited to forward- looking infrared, millimeter wave radiometry, millimeter wave radar, or low-light level image intensification.

  electronic means to provide a display of the forward external scene topography (the natural or man−made features of a place or region especially in a way to show their relative positions and elevation) through the use of imaging sensors, including but not limited to forward−looking infrared, millimeter wave radiometry, millimeter wave radar, or low−light level image intensification. An EFVS includes the display element, sensors, computers and power supplies, indications, and controls. An operator’s authorization to conduct an EFVS operation may have provisions which allow pilots to conduct IAPs when the reported weather is below minimums prescribed on the IAP to be flown.
