What does EFVS mean in Aviation?


Number Title
§ 91.176 Straight-in landing operations below DA/DH or MDA using an Enhanced Flight Vision System (EFVS) under IFR
§ 61.66 Enhanced Flight Vision System (EFVS) Pilot Requirements

What does Efvs stand for?

Enhanced Flight Vision System
EFVS is the acronym for Enhanced Flight Vision System. Simply put, it’s a flight system that uses different image and sensing technologies, like high-definition video, forward-looking infrared (both Near IR and Long-Wave IR), millimeter wave radar, and low-light image intensification.

What is an enhanced visual system?

Enhanced Vision (EV) and Synthetic Vision (SV) are two technologies that can help. These aircraft-based sensors use near-infrared cameras or millimeter wave radar to provide vision in limited visibility environments. EV systems can identify terrain in weather, and detect wildlife or other obstructions on the runway.

What is the FAA definition of an aircraft?

Aircraft means a device that is used or intended to be used for flight in the air. Airplane means an engine-driven fixed-wing aircraft heavier than air, that is supported in flight by the dynamic reaction of the air against its wings.

What is synthetic vision in aircraft?

A synthetic vision system (SVS) is an aircraft installation that combines three-dimensional data into intuitive displays to provide improved situational awareness to flight crews. This improved situational awareness can be expected from SVS regardless of weather or time of day.

Do Jets have night vision?

Fighter jets do have a normal cockpit lighting in them. Occasionally crews do use night vision goggles, not for viewing instruments, but visual reference outside the jet, and cockpit lighting can be adjusted for NVS systems.


An enhanced vision system (EVS) is an electronic means to overlay an image of the forward surrounding topography on a head up display (HUD), allowing the pilot to see the surrounding terrain in low visibility conditions.

How does the FAA classify aircraft?

Categories of aircraft for certification of airmen include airplane, rotorcraft, glider, lighter-than-air, powered-lift, powered parachute, and weight-shift control aircraft.

What three main aviation products does the FAA certify?

The Federal Aviation Administration (FAA) certifies three types of aviation products: Aircraft. Aircraft Engines. Propellers….Size and weight are other methods used in 14 CFR 1.1 to group aircraft:

  • Large Aircraft:
  • Light-Sport Aircraft:
  • Small Aircraft:

How much is the Garmin g1000?

The G1000 NXi upgrade for these aircraft is available for a list price of $28,995 from Garmin Authorized Dealers (installation and hardware charges may apply), which includes the avionics system software and STC Letter of Authorization (LOA) from Textron Aviation for list price of $4,000.

Can pilot see the runway?

To complete a safe landing, pilots must be able to see the runway at a specific decision height (DH) above the ground. A minimum horizontal visibility is also specified, called the Runway Visual Range, or RVR. The RVR is measured on the ground, and the information given to the pilots before they begin an approach.

What is an enhanced flight vision system (EFVS)?

The forward-facing camera used for the PlaneView EVS on a Gulfstream G450. An Enhanced flight vision system (EFVS, sometimes EVS) is an airborne system which provides an image of the scene and displays it to the pilot, in order to provide an image in which the scene and objects in it can be better detected.

What does EFVS mean on a Gulfstream?

The Gulfstream system is certified to take advantage of 14 CFR 91.175, so where the regulation says EFVS, in the Gulfstream fleet that means EVS. [ AC 90-106A, ¶] EFVS Operations to Touchdown and Rollout.

What are the components of an EFVS?

An EFVS includes the display element, sensors, computers and power supplies, indications, and controls.” [ AC 90-106A, ¶2.3.1] An EFVS uses a transparent HUD or equivalent display to combine flight information, flight symbology, navigation guidance, and a real-time image of the external scene to the pilot on one display.

What is an EFVS operation to 100 feet above the TDZE?

An EFVS operation to 100 feet above the TDZE is an operation in which the pilot uses the enhanced vision imagery provided by an EFVS in lieu of natural vision to descend below DA/DH or MDA down to 100 feet above the TDZE. Natural vision must be used to descend below 100 feet above the TDZE.
