Which components are typically included in an aircraft VOR system?

The correct answer includes the essential components of an aircraft VOR (VHF Omnidirectional Range) system, which are crucial for determining an aircraft's position relative to a navigational aid. The receiver is the device that picks up VOR signals transmitted by ground stations, allowing the aircraft to determine its bearing. The control box is used by the pilot to input desired course and make necessary adjustments during flight. The course deviation indicator displays the aircraft's position in relation to the selected VOR radial, showing whether the aircraft is on course or needs to correct its heading. Together, these components enable pilots to effectively navigate using VOR signals during their flight operations.

In contrast, the other options contain components that are not typically associated with the VOR system. GPS and autopilot systems are related to modern navigation techniques, but do not form part of the VOR. Flight data recorders and transponders serve different purposes in aviation, primarily related to recording flight data and aircraft identification, respectively. Lastly, while communication radios and weather radar are important for overall flight safety and navigation, they are separate systems that do not contribute directly to the VOR's functionality.
