Inventor-directed decision aid

Recommend charge at droplet formation

This aid extends the SPE method. It does not fly the aircraft or replace inventor-directed calibration.

DEMO recommendation
Calibration hold
Recommended charge band at formation
4,900–5,200 V
Underside-coverage risk
Moderate · verify crosswind
Formation logic
Charge before droplet release

SPE applies electrical charge at droplet formation inside the pressurized hydraulic nozzle, rather than pneumatically charging an already-formed droplet. Verify boom geometry and valve logic before acceptance.
