Measuring Apparatus for Checking an Approach Path Indicator for the Landing of an Aircraft, and Corresponding Checking Device

A device for checking a light unit comprising:

• a mobile apparatus for measuring characteristics of a light beam emitted by a light unit, presenting at least two angular portions of different colors, said apparatus comprising a support that enables the position of a measuring set to vary, wherein the measuring set comprises a single orientable camera, equipped with a zoom element capable of taking at least two positions:
• a first position of low magnification, offering a low magnification and a wide field angle, enabling detection of the position of the light unit to orient the camera precisely in its direction;
• and
• a second position of high magnification enabling taking of an image of the light unit enabling an analysis of the characteristics of the light beam emitted by the light unit, and
• a computer configured by software to process data from the mobile apparatus for measuring, and
• an interface with an operator.
