The Jetsys Defence Protractor Unit for DAU Vane Angles is a high-accuracy measuring tool engineered for vane rigging, alignment, and calibration tasks. Built for MRO, line maintenance, and defence applications, this vane protractor aviation tooling provides repeatable, traceable measurements that help technicians meet strict aircraft OEM tolerances.
Product Overview
Our Protractor Unit for DAU Vane Angles offers precise angle measurement for stall/alpha vanes, DAU vane sensors, and variable vane assemblies. The rugged body, stable mounting hardware, and positive-lock indexing ensure dependable use on the ramp and in the shop.
- Primary use –Measurement and setting of DAU vane angles.
- Secondary use –Control surface and sensor alignment where angle verification is required.
- Available forms –Digital readout or high-visibility analog dial, both offering fine resolution.
Key Features of Protractor Unit for DAU Vane Angles
- High accuracy & resolution –Fine-grade encoder or dial ensures precise angle sensing for tight vane tolerances.
- Stable mounting –Aircraft-safe clamps with optional suction or magnetic bases maintain alignment without damaging painted surfaces.
- Fast rigging workflow –Zero-set, hold, and relative-angle modes speed up calibration and reduce rework time.
- Robust aviation build –Impact-resistant housing, Skydrol-resistant finishes, and sealed bearings ensure long service life in demanding GSE environments.
- Documentation & traceability –Optional factory calibration certificate and maintenance checklist support airworthiness compliance and record-keeping.
