INDICATORS (PAPI)
PAPI systems with remote on-off switching shall be
operated when they serve the runway in use and
where intensities are controlled in accordance with
TBL 3-4-4 except:
a. As required by local facility directives to meet
local conditions.
b. As requested by the pilot.
NOTEThe
basic FAA standard for PAPI systems permits
independent operation by means of photoelectric device.
This system has no on-off control feature and is intended
for continuous operation. Other PAPI systems in use
include those that are operated remotely from the control
tower. These systems may consist of either a photoelectric

3-4-5. APPROACH LIGHTS
Operate approach lights:
a. Between sunset and sunrise when one of the
following conditions exists:
1. They serve the landing runway.
2. They serve a runway to which an approach is
being made but aircraft will land on another runway.
b. Between sunrise and sunset when the ceiling is
less than 1,000 feet or the prevailing visibility is
5miles or less and approaches are being made to:
1. A landing runway served by the lights.
2. A runway served by the lights but aircraft are
landing on another runway.
3. The airport, but landing will be made on a
runway served by the lights.
c. As requested by the pilot.
d. As you deem necessary, if not contrary to pilot's
request.

accordance with the values in TBL 3-4-5 except:
a. When facility directives specify other settings
to meet local atmospheric, topographic, and twilight
conditions.
