What is the difference between a PAPI and a VASI?
The only functional differences between the VASI and PAPI is that the VASI has the red over the white, the PAPI the white actually goes to the right of the red, and the PAPI offers higher precision (or more glideslopes depending how you look at it a larger airliner with a high cockpit may elect to fly a slightly higher …
What does PAPI and VASI stand for?
Precision Approach Path Indicator
The Precision Approach Path Indicator (PAPI) uses light units similar to the VASI, but are installed in a single row of either two or four light units. These lights are visible from about 5 miles during the day and up to 20 miles at night.
How does a VASI work?
How Does a VASI Work? The individual lightboxes that make a VASI work are made of two light bulbs with a solid divider between them. The red light is below the white light. The box itself is mounted to the ground at the angle at which you want the light to change.
What does VASI stand for in aviation?
A visual approach slope indicator system is a system consisting of four light units situated on the left side of the runway in the form of two wing bars referred to as the upwind and downwind wing bars.

What should the VASI or PAPI lights be visible at?
As you come in for landing, at what angles should the VASI or PAPI lights be visible on the approach in the Horizontal and vertical planes. {E.G. 30 degrees horizontal and 20 degrees vertical} This information is for the US, taken from FAA Order 6850 – Visual Guidance Lighting Systems. a. Layout b. Aiming
What should the horizontal field of view be on a VASI?
The two-bar VASI system shall have the upwind bar aimed at three degrees and the downwind bar aimed one-half degree lower at 2.5 degrees; however, where necessary to provide obstacle clearance, the downwind bar may be aimed at 2.75 degrees. d. Horizontal field of view: 10°
When to follow the VASI on final approach?
These lights are visible from 3-5 miles during the day and up to 20 miles or more at night. The visual glide path of the VASI provides safe obstruction clearance within plus or minus 10 degrees of the extended runway centerline and to 4 NM from the runway threshold. If you see two red lights over two white lights, you’re on glide path.
What should the slope of a VASI be?
If you are slightly high, the three outer lights will be white and the innermost light will be red. If you are slightly low, you will have one white light and three red lights. Too high (As in above 3.5 degrees) you will have all white. Too low (less than 2.5 degrees) will indicate all red.
