[The] LLWSAS system... is marketed under the trade name LOLA, for low level alert. LOLA is a turnkey system consisting of an array of wind sensors, located on the ground, at and around an airport... The LOLA system is directed by a IBM central control unit with varied communications(VHF/UHF radio or land line) to interrogate the remote sensor sites at least once every 10 seconds. Currently, the two-minute running average of the centre-field site is the reference value from which the shears(at 15-knot threshold value to trigger the alarms) are detected. 4, record 1, English, - low%20level%20wind%20shear%20alert%20system

Le LLWSAS est un système de saisie, d'analyse et d'affichage de données exploité en temps réel et commandé par micro-ordinateur. Il recueille des données sur la direction et la vitesse du vent au moyen de six anémomètres; un anémomètre central est implanté près du centre de l'aéroport et cinq anémomètres périphériques sont placés près des zones d'approche et de décollage. 2, record 1, French, - syst%C3%A8me%20d%27alerte%20cisaillement%20du%20vent%20%C3%A0%20basse%20altitude
