Electrical, Photometric, Colorimetric, Effective Luminous Intensity, Luminous Range Measurements of Aviation Aids to Navigation Signal Lights are performed in accordance with FAA regulation.

Effective Intensity Measurements are evaluated depending of the form and operating mode of the flash using an oscilloscope and a very fast photometric detector to capture the light output.

Effective Intensity Measurements are evaluated based on the form of the flash using :

- Schmidt Clausen Method also called Form Factor Method

- Allard Method

- Modified Allard Method
