area.
c. It is determined that the lights are of no further
use to the pilot.

portions thereof, in use between sunset and sunrise
before an aircraft taxies onto the taxiway (normally
at the time taxi information is issued) and until it
taxies off it.
11-1-18. VISUAL APPROACH SLOPE
INDICATORS (VASIs)
The VASI system with remote on-off switching shall
be operated when it serves the runway in use and
where intensities are controlled in accordance with
TBL 11-1-7 and TBL 11-1-8.
TBL 11-1-7
VASI Intensity Setting, Two-Step System
Step Period: Condition
High Day: Sunrise to sunset.

NOTE-
1. During a 1-year period, twilight may vary 26 to 43
minutes between 25 and 49 degrees N latitude.
2. The basic FAA standard for VASI systems permits
independent operation by means of photoelectric device.
This system has no on-off control feature and is intended
for continuous operation. Other VASI systems in use
include those that are operated remotely from the control
tower. These systems may consist of either a photoelectric
intensity control with only an on-off switch, a two-step
intensity system, or a three-step intensity system.

a. Where RVR/RVV equipment is operational,
irrespective of subsequent operation or nonoperation
of navigational or visual aids for the application of
RVR/RVV as a takeoff or landing minima, furnish the
values for the runway in use in accordance with
para 11-1-20, RVR/RVV.
