V8BP.000-01

Crew visibility through the V8BP.000-01 glass

Side visibility is important for helicopter operation, especially during taxiing, hovering, approach, landing and maneuvering near obstacles. The V8BP.000-01 allows the pilots to monitor the area around the helicopter through the side section of the cockpit glazing. If the glass is cracked, fogged, iced or has optical defects, the crew’s field of view can be reduced. This is why the glass is checked not only for physical damage, but also for transparency, lamination condition and correct operation of the heating circuit.

Anti-icing and anti-fogging function of V8BP.000-01

The V8BP.000-01 performs anti-icing and anti-fogging functions through an integrated film-type electric heater. When powered, the heating layer warms the glass and helps prevent ice formation on the outer surface and fogging on the inner surface. This is especially important when the helicopter operates in low temperatures, precipitation, high humidity or during temperature transitions between the cockpit and outside air. Stable heating helps the pilots keep a clear visual field without relying only on cockpit ventilation or airflow.

Laminated triplex construction of V8BP.000-01

The V8BP.000-01 is manufactured as laminated triplex safety glass. According to the supplied description, the unit consists of two flat silicate glass layers bonded together with a transparent interlayer. This construction improves mechanical strength and helps the glass maintain safer behavior if damaged. For cockpit use, the glass must combine visibility, structural resistance and stable operation of the heating element. During inspection, attention should be paid to cracks, delamination, edge chips, optical distortion, surface damage and the condition of the electrical heater terminals.

Electric heating of V8BP.000-01 through AT-8-3

The heating function of the V8BP.000-01 is provided by the integrated film electric heater. The glass operates as part of the cockpit glazing anti-icing system and is powered through the AT-8-3 autotransformer. When troubleshooting the heating system, it is important to check not only the glass itself, but also the wiring, connectors, control circuit and autotransformer output. Uneven heating, slow warming or complete loss of heating may be caused by damage inside the glass heater or by faults in the external electrical circuit.

Application of V8BP.000-01 on Mi-8 series helicopters

The V8BP.000-01 is intended for helicopters of the Mi-8 and Mi-171 family, including Mi-8MTV-1 and Mi-8AMT, depending on cockpit glazing configuration. It is installed as a cockpit side window and belongs to the glazing anti-icing system. Before replacement, the passport designation, dimensions, thickness, installation side, contour and electrical connection should be checked against the aircraft parts catalog and maintenance documentation. Heated cockpit glass items may look similar, but differ by modification, heater layout or connector arrangement.

Supply and documentation for V8BP.000-01

For procurement, the passport designation V8BP.000-01 should be stated clearly, with the Cyrillic version В8БП.000-01 included where required by documentation. The glass is typically supplied as a separate electrically heated glazing unit with product passport. Before installation, the unit should be inspected for transport damage, lamination quality, optical clarity, heating element continuity and correct dimensions. For aircraft use, the passport confirms the designation, acceptance and suitability of the glass for the required helicopter modification.
