Pilot Сoсkpit

1. That portion of the airplane, occupied by pilots is the pilot's cockpit. From this cockpit all controls used in flying and landing radiate. All the instruments and equipment are installed in accessible positions. Single-place airplanes have one cockpit (accommodations for the pilot only). Two-place airplanes usually have two cockpits in tandem, although some airplanes have single cabin with two seats side by side. A cargo or other large or special type airplane has a pilot's compartment or control room in addition to the cabin. Most cockpits and cabins are completely enclosed to protect the pilot and the crew from atmospheric conditions.

2. All control systems terminate in the cockpit; all operational and navigational instruments are located here. All decisions regarding the flight of the airplane, with very few exceptions when the airplane is about to take off and land, are determined here.

3. It is necessary to locate the seat of the pilot in the cockpit so that he may have sufficient vision in all possible directions, with special attention to forward, upward, downward and sideward vision.

4. All switches and controls which the pilot must operate should be located as close to him as possible so that it will be unnecessary for him to stretch.

5. Thus the cockpit for an airplane should be constructed to give the maximum possible comfort, adequate vision and accessibility to all controls.
