PQRS Glint and Glare Analysis

The PQRS Glint and Glare Simulation Tool quantifies:

When glare can occur (time-of-year and time-of-day)
Where glare can be observed (at defined receptors)
Potential ocular impact and hazard boundaries based on FAA 2021 and other international aviation policies.

Map tools

Choose a tool, then click the map.

Suggested order: locate site → fetch ASL → draw array(s) → mounting plane & module angles → vertex heights → receptors → run.

1. Find the site — drag the map, search an address, or type lat/lon. The blue Site Reference Point only needs to be near the project.

Find address

Latitude Longitude

2. Ground elevation (m ASL)

Fetch approximate ground height above sea level (public elevation data). Analysis heights = ground + height above ground (vertex / eye / cab).

Site reference ground (m ASL)

No DEM yet — heights are AGL only (flat relative ground).

3–5. Draw each footprint, then set that array’s mounting plane, module angles, and vertex heights (select an array in the list to edit it).

3. Arrays

Array area: —

Vertices: 0 (need ≥3, then lock shape)

4. Mounting plane (active array)

Orientation of the mounting surface used for vertex heights (LOW → HIGH on the map). For flat ground-mount, leave pitch at 0 so every corner stays at the base AGL. This is not module tilt — set module tilt under §5.

Array plane pitch (°) High-edge bearing (° N CW)

Flat plane — use base height below for all corners, or edit each vertex.

5. Module angles (active array · glare optics)

Tilt and azimuth of the PV modules — required for the glare calculation. Set per array; each array can differ.

Module tilt (°) Module azimuth (° N CW)

Vertex heights (active array)

Set base height above ground, then optionally type a different AGL for each numbered corner (map badges 1, 2, 3…). Changing plane pitch / base height recalculates all corners from the plane.

Base / low-edge height (m AGL)

OP eye height for next click (m AGL)

Set height, then click the map to place the observation point.

ATCT cab height for next click (m AGL)

Set cab height, then click the map to place the tower cab.

After placing, edit heights in the list below — that value is what the analysis uses.

Placed receptors

Click 1 on runway centreline, click 2 at the threshold. A 2‑mile approach is auto-extended (standard 3° glide, 50 ft TCH).

Flight paths: none

Analysis settings

Shared sky / reflectance settings for the run. Module tilt and azimuth are set per array under Draw array.
