Final answer:
The 2 bar VASI is for aircraft with an eye to wheel height of up to 2 meters.
Step-by-step explanation:
The VASI system is a visual aid installed at many airports to assist pilots in maintaining the correct glide path during approach and landing. It consists of a series of lights arranged in two bars, each with two or three lights. The lights are typically white and red, with the white lights indicating that the aircraft is above the desired glide path and the red lights indicating that the aircraft is below the glide path.
The 2 bar VASI system is specifically designed for aircraft with an eye to wheel height of up to 2 meters. This means that the height from the pilot's eye level to the aircraft's wheels should not exceed 2 meters. This information is important for pilots to ensure that they can accurately interpret the visual guidance provided by the VASI system and maintain the correct glide path during approach and landing.
