The visual approach slope indicator (VASI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during approach. These lights may be visible from up to 8 kilometres (5.0 mi) during the day and up to 32 kilometres (20 mi) or more at night.
Famous quotes containing the words visual and/or approach:
“For women ... bras, panties, bathing suits, and other stereotypical gear are visual reminders of a commercial, idealized feminine image that our real and diverse female bodies can’t possibly fit. Without these visual references, each individual woman’s body demands to be accepted on its own terms. We stop being comparatives. We begin to be unique.”
—Gloria Steinem (b. 1934)
“Oh! mystery of man, from what a depth
Proceed thy honours. I am lost, but see
In simple childhood something of the base
On which thy greatness stands; but this I feel,
That from thyself it comes, that thou must give,
Else never canst receive. The days gone by
Return upon me almost from the dawn
Of life: the hiding-places of man’s power
Open; I would approach them, but they close.”
—William Wordsworth (1770–1850)
