Identifier: 16
Scope and Contents MIT DIC 6673. Project Whirlwind Report R-191. A schedule-following system for an airplane is a servomechanism. By use of conventional design techniques the system can be made to operate successfully up to the limits of the fixed part of the system, which is the airplane itself and the navigation system. For a Lockheed Constellation and an accurate (± 250 feet) navigation system, the speed control can have a bandwidth of about 0.4 cycle per minute and a speed range of about ± 15 percent of...
