VASI. See visual approach slope indicator.
VDP. See visual descent point.
Vectoring. Navigational guidance by assigning headings.
VASI: A pair of lights adjacent to the runway that indicate to the pilot whether his approach is too high, too low, or just right.
VSI: Vertical Speed Indicator; tells how fast your're going up or down.

VASI (visual approach slope indicator
Have two for G.A. aircraft or three bars for 747 types.
"Red over White, you're all right."
Three bar VASIs will have two red over white for G.A. aircraft.
VASI: ≡ visual approach slope indicator, 12
Venturi, 3.4.2

VOR: ≡ very-high-frequency omni range, 14.3.2
variometer, 1.2.4
vector, 14.2.4, 19.1, 19.9.2
vector (from ATC), 14.7.5, 15.1.
VOR, ILS, NDB, VASI, DME, MLS, are different navigation aids and need periodic flight inspection.
A more accurate VASI. This 4-light visual glideslope indicator is calibrated to display smaller deviations than a VASI.
