Which type of airspace is primarily used for VOR-NDB approaches?

• A. Class B airspace
• B. Class G airspace
• C. Class C airspace
• D. Class D airspace

Answer: (B)

The primary type of airspace used for VOR-NDB (VHF Omnidirectional Range and Non-Directional Beacon) approaches is Class G airspace. Class G airspace is uncontrolled airspace, where pilots are free to operate without air traffic control (ATC) clearance. This characteristic allows for greater flexibility and accessibility for VFR (Visual Flight Rules) traffic, as well as for aircraft conducting non-precision approaches like VOR-NDB. VOR-NDB approaches mainly serve areas where precise instrument landing systems (ILS) are not available, and they are especially useful in rural or less-trafficked regions typically associated with Class G airspace. While other classes of airspace, such as Class B, C, and D, can facilitate instrument approaches, they generally involve ATC service and procedures, which are not the focus of VOR-NDB approaches. These other classes often require more stringent communication protocols and present a higher density of air traffic, making them less ideal for the flexibility and simplicity of VOR-NDB operations.
