Totem Tray Harmonization Tool – Indigenized Runway Alignment System
Jetsys Defence introduces a fully indigenized Totem Tray Harmonization Tool, engineered for precise runway light alignment and optical harmonization. Designed for defence and commercial aviation, it enables technicians to accurately align runway approach lights, PAPI, VASI, touchdown lighting, and other AGL systems without heavy setup, external targets, or weather dependencies.
This system improves operational readiness, reduces maintenance time, and provides superior accuracy over conventional mechanical alignment procedures.
What is a Totem Tray Harmonization Tool?
A Totem Tray Harmonization Tool is a precision-engineered optical alignment instrument used to set the beam angle and convergence of runway lighting equipment. It projects a calibrated optical reference that technicians use to adjust light trays to exact ICAO-defined angles.
Why is Harmonization Required?
- Ensures every runway light emits a correct beam height and axis
- Critical for night operations and low-visibility landings
- Prevents uneven illumination zones that affect pilot visibility
- Helps airports maintain international compliance
Key Features – Totem Tray Harmonization Tool
- Collimated reference for stable beam datum (azimuth & elevation)
- Fine-pitch micrometer adjusters for sub-degree tuning (±0.1° class)
- Dual-axis alignment with clear sighting reticle/telescope
- Repeatable tray positioning for uniform runway light patterns
- Works with LED, halogen, inset, elevated, PAPI/VASI fixtures
- Aircraft-grade aluminium chassis; weather-resistant gasketing
- Rechargeable battery pack or external 12 V input
- Shock-protected optics and hard carry case
- One-person setup; no long-range targets or aircraft levelling
- Tool-less field adjustments; quick clamp/lock interfaces
- Non-intrusive to flight ops; minimal closure time
- Alignment aides mapped to ICAO-style photometric aims
- Includes calibration sheet, user checklist, and maintenance log
