Sliding window, with fittings

Sliding windows in the side panels are not only useful for large helicopters, they also serve safety.
The door or cabin entrance remains closed for the quick transfer of small items because the sliding windows can be used to pass them through.
If cracks appear in the windshield after the impact of foreign bodies, vision becomes impossible. Then the view only passes through the open sliding windows in the side windows.
Suitable for all model sizes.
