3.5 Visual Approach Slope Indicators (VASI) Flashcards
when approaching to land on a runway served by a visual approach slope indicator (VASI), the pilot shall
maintain an altitude at or above the glide slope
A below glide slope indication from a pulsating approach slope indicator is a
pulsating red light
while operating in class D airspace each pilot of an aircraft approaching to land on a runway served by a visual approach slope indicator (VASI) shall
maintain an altitude at or above the glide slope until a lower altitude is necessary for a safe landing
which approach and landing objective is assured when the pilot remains on the proper glidepath of the VASI
safe obstruction clearance in the approach area
Each pilot of an aircraft approaching to land on a runway served by a visual approach slope indicator (VASI) shall
maintain an altitude at or above the glide slope
(refer to image) Illustration A indicates that the aircraft is
on the glide slope
(refer to image) While on final approach to a runway equipped with a standard 2-bar VASI, the lights appear as shown by illustration D. This means that the aircraft is
below the glide slope
(refer to image) VASI lights as shown by illustration C indicate that the airplane is
above the glide slope
which approach and landing objective is assured when the pilot remains on the proper gildepath of the VASI
safe obstruction clearance in the approach area
A slightly high glide slope indication from a precision approach path indicator is
three white lights and one red light
