Question: 1 / 400

What is the maximum allowable error when flying directly over a published airborne VOR checkpoint for IFR flight?

Plus or minus 6° of the designated radial.

The maximum allowable error when flying directly over a published airborne VOR checkpoint for IFR flight is indeed plus or minus 6° of the designated radial. This tolerance is set to ensure that pilots maintain an acceptable level of accuracy when navigating using VOR (VHF Omnidirectional Range) navigational aids. It permits some deviation due to various factors such as aircraft equipment errors, signal strength, and environmental conditions that may affect the VOR signal and the aircraft's navigation systems.

By adhering to this standard, pilots can ensure that they remain within safe operational parameters even when there might be slight discrepancies in the reading of the VOR system. Understanding this detail helps reinforce the importance of navigation accuracy, especially in IFR conditions, where following precise flight paths is crucial for safety and compliance with air traffic control directives.
