Final answer:
The normal range of L class VORs is 40 nautical miles and H class VORs is up to 100 nautical miles at 1000ft AGL, with variations depending on terrain and atmospheric conditions.
Step-by-step explanation:
The normal range of L and H class VORs (VHF Omnidirectional Range) at 1000ft Above Ground Level (AGL) is as follows: L class VORs typically have a range of 40 nautical miles, while H class VORs have a range that can extend up to 100 nautical miles at 1000ft AGL. These ranges can be affected by various factors including terrain, installation, and atmospheric conditions.
VORs is a type of short-range radio navigation system for aircraft, enabling pilots to determine their position and stay on course via radio signals transmitted by a network of fixed ground radio beacons. It is worth noting that the actual reception range may vary due to specific factors at the time of the flight, despite the stated normal operational ranges.
