__________________________________________________
R 1. General
_______ R The environment protection system is divided into: R - the protection of the wing leading edge, R - the protection of the pylon, R - the protection of the nacelles.
A. Protection of the Wing Leading Edge, the Pylon and the Nacelles The protection systems of the wing leading edge, the pylon and the nacelles keep the pressure in these areas to a limit. The protection systems operate if a pneumatic duct or a wing anti-ice duct bursts or has a large leak. This prevents damage to the structure and the systems installed.
