Photometric Measurement System for Precision Approach Path Indicator Units
SMF/PAPI (Precision Approach Path Indicator)
An Optoelectronic Sensor head mounted on a auto leveling 3D moving mechanism driven by an embedded PC running an image analysis software and remotely controlled with a Tablet PC.
Easy to use and to deploy in the field.
Angle measurement is available immediately including the instructions on how to correct the PAPI unit position if necessary.
Measures the beam real angle with an accuracy better than 1°.
Measures all photometric parameters requested by ICAO.
Reveals any problem in the PAPI projector including defocusing issues.
At the end of measurement the following information will be displayed:
PAPI unit elevation angle .
PAPI transverse tilt angle (optical horizontality of the unit).
Transverse tilt of the single beams (horizontality of the red filters inside the unit).
Instructions to the operator for a proper alignment of the PAPI unit .
System software will also warn the operator if the PAPI unit is showing unfocused or misaligned optics.
