confined area
- Definição1
- A confined area is an area where the flight of the heli- copter is limited in some direction by terrain or the presence of obstructions, natural or manmade. For example, a clearing in the woods, a city street, a road, a building roof, etc., can each be regarded as a confined area.

- Nota adicional1
- Generally, takeoffs and landings should be made into the wind to obtain maximum airspeed with mini- mum groundspeed.
- Nota adicional2
- There are several things to consider when operating in confined areas. One of the most important is maintaining a clearance between the rotors and obstacles forming the confined area. The tail rotor deserves special considera- tion because, in some helicopters, you cannot always see it from the cabin. This not only applies while making the approach, but while hovering as well. Another consider- ation is that wires are especially difficult to see; however, their supporting devices, such as poles or towers, serve as an indication of their presence and approximate height. If any wind is present, you should also expect some turbulence.
- Contexto
- Confined spaces take-offs. One of the most common causes of water take-off occurrences is the pilot attempting to take off from a confined water surface with a heavy or overloaded aircraft. Confined area operations may also be adversely affected by wind conditions.
