Question

EUs with weather equipment sensors installed near the approach end of two or more runways will use the sensors installed at the active (approach) end of the runway when the equipment is operational and considered reliable. If cloud height equipment for the active runway is inoperative, data obtained from the inactive runway (or alternate runway) equipment may be used if the measurements are considered representative. True or False?

Answer 1

True, air traffic controllers use sensors at the active runway and can use alternative runway sensors if necessary and representative.

Step-by-step explanation:

True, when the weather equipment sensors installed near the approach end of runways are operational and considered reliable, air traffic controllers will use the sensors installed at the active (approach) end of the runway. If the cloud height equipment for the active runway is inoperative, they have the option to use data from the inactive runway (or alternate runway) equipment, provided that the measurements are considered representative of the actual conditions. This protocol ensures that flight operations can continue safely even in adverse weather conditions such as clouds, wind, and rain, which could otherwise limit visibility and hinder the safe management of air traffic in the manner that radar instruments can probe through perpetual cloud layers that might obscure visibility.
