What must be stated when the clearance is for a NAVAID?

When a clearance is specifically for a Navigational Aid (NAVAID), it is essential to identify the type of NAVAID involved. This helps ensure that pilots clearly understand which navigation aid they are expected to use for their route or approach. Different types of NAVAIDs, such as VORs (VHF Omnidirectional Range), NDBs (Non-Directional Beacons), or ILS (Instrument Landing System), provide varying support and guidance depending on their function and purpose.

By stating the type of NAVAID when giving clearance, controllers provide critical context that aids pilots in their navigation and enhances safety during flight operations. This level of specificity can help prevent confusion, especially when multiple NAVAIDs might exist in close proximity.

While altitude, location, and departure point are important elements of ATC communication, they do not directly pertain to the specificity required when a clearance is exclusively for a NAVAID, making the identification of the type of NAVAID the most relevant and necessary information in this context.
