Table 14-6. Checklist for PAPI
____ 1. Is all equipment and material new? [Items covered by the FAA L-800 series should
be listed in the FAA AC 150/5345-53]
____ 2. Is the location of PAPI light boxes according to plans?
[Distance from threshold, distance from runway edge, distance between light boxes.]
____ 3. Are the foundations and equipment mountings according to plans, and do breakable
couplings not exceed allowable height?
____ 4. Is the positioning and aiming of the light units in a bar in accordance with
requirements?
____ a. LONGITUDINALLY: In line perpendicular to the runway centerline within + 6
inches.
____ b. ELEVATION: In a horizontal plane within a tolerance of + 1 inch, and the
centers of the optical aperture of the light units within + 1 foot of the runway
crown.
____ c. AZIMUTH: Parallel to the runway centerline within a tolerance of +
degree.
____ d. VERTICAL AIMING: Within + 2 minutes of the specified angle for each light
unit.
[Aiming angles should be stencilled on each light box.]
____ 5. Is the aiming device and the optical bench properly calibrated and operational? Are
the optical systems, if required, properly focused?
____ 6. PHOTOCELL: Is the photocell properly aligned? Does it change the brightness of
the lamps? Is the time-delay (45-75 seconds) in the photocell operational?
____ 7. Does the tilt switch in each light unit operate when the unit is tilted down between
- degree, and also when tilted upward between - 1 degree?
____ 8. Does the lamp bypass, if included, operate with each bulb when the bulb is
disconnected?
____ 9. Is the current in the lamps within the limit for the high and low brightnesses?
____ 10. Are the lamps of proper wattage? Is the selected low brightness correct for local
conditions?
____ 11. Is the voltage at the adapter unit with the facility at full brightness within the specified
voltage limits?
____ 12. Does the megger test indicate satisfactory cable insulation resistance?
____ 13. Has a carrying case for the aiming device been provided?
____ 14. In case of adapter-fed PAPI, are the connectors at the breakable couplings of the
correct type?
____ 15. When regulator feed PAPI system is installed, are isolation transformer connections
to the lamp housings made by using cable harness assemblies meeting specification
FAA-1041, Figure 5b and 5d?
