Glide Path

Hename designed GP with the customers’ requirements in mind interviewing many ILS maintenance experts. One of our main goals with system design was to considerably reduce the complexity and amount of time the field engineer spends on their maintenance work. In addition the careful and thoughtful preparation in our factory is producing the fault free equipment.

Recognizing the need for a sustainable equipment running under harsh environment, we reflected every possible temperature compensation circuit on the systems.
Whether the airport is highly populated or less populated, our GP is sure to meet all demands. Upgrading from CAT I through CAT II to CAT III is very easy, every unit we are releasing from our factory is CAT III ready, supporting long term growth success.

Thanks to thorough consideration on temperature compensation Mercury ILS can immediately and instantly stablize every critical parameter after power tun ON of transmitter. This feature is especilly valuable for the airport with cold standby configuration of ILS.
