These readings also assist Airport Traffic Control (ATC) when issuing control instructions to avoid interfering operations within ILS critical areas at controlled airports. The RVR reading is key to determining the category of precision approach capability required to conduct safe aircraft operations. During reduced visibility weather conditions, RVR system measurements are used by air traffic controllers to establish airport operating categories. The data is used to decide whether it is safe to take off or land during limited visibility conditions. The RVR equipment are located next to a runway that provide air traffic controllers with a measurement of the visibility at key points along a runway (e.g., touchdown, midpoint, and rollout). MALSRs consist of a combination of steady burning light bars and flashers that provide pilot's visual information on runway alignment, height perception, roll guidance, and horizontal references. RVR is a critical component in determining what the ILS minimums will be for each landing Category. The MALSR is a medium-intensity approach lighting system (ALS) installed in airport runway approach zones along the extended centerline of the runway. Recreational Flyers & Modeler Community-Based Organizations.Critical Infrastructure & Public Venues.My question is, why not use SSALR instead, which is basically the same thing, but high intensity lights. Certificated Remote Pilots including Commercial Operators As you can see, the vast majority of CATI runways have MALSR approach lights, which is a medium intensity approach lighting system with runway alignment indicator lights (sequenced flashers).Legislation & Policies, Regulations & Guidance.Distance from the decision bar at DH MALSR light bars are spaced at 200 foot. Data & Research Subnav: Data & Research 1 The ALS is an airport lighting system that projects light in a directional.The threshold light array consists of 18 to 33 aviation green steady burning lights depending on runway width, arranged in a line at and parallel to the threshold of the runway.

Powder coated orange, other colours available Once the elevator is fully lowered, the 12m frangible portion can be further lowered using a screwjack where it can be serviced from the ground. The frangible tower can be installed on a platform (elevator) that can be raised and lowered alongside a steel tower. Frangible towers are typically lowerable onto a steel platform where they can be serviced. Gantry designs typically extend for multiple positions allowing multiple towers to be serviced with a single climb. The frangible tower can be installed on a freestanding steel tower or gantry. The column can either be fixed or lowerable via rope-and-pulley and a counter-weighted system. The frangible tower is supported by a hot-dipped galvanized steel column. For positions that exceed 14.50m, Millard offers a variety of solutions that comprise of a steel base structure and a 12m frangible tower. Depending upon an airport’s access to equipment and to the tower site, designs can be economically fixed for crane access, or engineered to be lowered for servicing from the ground or elevated platform. Per ICAO, only the upper 12m of a tower is required to be frangible.
