  • Park Air Training

    The Park Air Academy – a purpose-built facility – offers comfortable and uninterrupted learning for the students in a pleasant environment. Park Air offers training courses for users responsible for the acquisition, installation, support and maintenance of Park Air ATM communications systems; both beginners and advanced. Courses are developed by technical experts and delivered by professional trainers with extensive experience.

    We use the latest blended learning techniques – students will receive information in a number of ways: visual, auditory, touch, peer learning group exercises, individual exercises, video, and calculations. This concept of blended learning is more effective than purely face-to-face or purely online classes.
