<strong>Potsdam</strong> Municipal Airport - Master Plan – Phase 1 Report<br />
Precision Approach Path Indicators (PAPI)<br />
PAPIs are <strong>us</strong>ed to provide visual glide slope guidance for non-precision or visual<br />
approaches. The PAPI system is composed of two lights that are installed in a line<br />
perpendicular and to the left of the runway. When an aircraft is on the correct glide<br />
slope angle, the PAPIs will emit one white and one red light. Other light<br />
combinations can indicate when an aircraft is too high (two white) and too low (two<br />
red). The PAPI system for Runway 6-24 is currently in excellent condition and the<br />
locations are designated with the letter “P” on Figure 2-10.<br />
Rotating Beacon<br />
The location of an airport at night is universally indicated by a rotating beacon that<br />
projects two beams of light, one white and one green, 180 degrees apart. The beams<br />
of white and green light indicate that the airport is a lighted civil land airport. The<br />
Airport has a rotating beacon that is in excellent condition. It is located adjacent to the<br />
electrical building and is depicted as a star on Figure 2-10.<br />
