Final answer:
The maximum distance for reception between VOR navigational facilities below 14,500' AGL depends on various factors, but a general range is about 40-50 nautical miles.
Step-by-step explanation:
The maximum distance you can file a direct route between two VOR navigational facilities below 14,500' AGL and be assured reception depends on various factors such as the power output and antenna system of the VOR stations, the terrain, and atmospheric conditions. However, a general rule of thumb is that VOR signals typically have a range of about 40-50 nautical miles. Keep in mind that this range can be affected by obstacles such as mountains, buildings, or radio interference.
