When performing an airborne VOR receiver check using a created checkpoint, what is the first step?

The first step when performing an airborne VOR receiver check using a created checkpoint is to select a VOR radial that defines the centerline of an airway. This is essential because the VOR radial serves as a reference point for determining the accuracy of the VOR navigation signal. By aligning your aircraft with this radial, you can accurately assess the performance of the VOR receiver while ensuring that you are on the correct flight path. Additionally, selecting a designated radial that corresponds with the airway ensures compliance with procedural standards and enhances situational awareness.

This step is foundational to conducting a valid VOR receiver check, as it allows for the proper calibration of navigational instruments, ultimately contributing to safety and operational efficiency during flight. Once the radial is established, other steps can be taken, such as positioning the aircraft and observing external references, but the radial selection is the crucial starting point.
