In the PAR, the display is divided into which two sections?

• A. Azimuth and elevation data; range data
• B. Azimuth data; elevation and range data
• C. Range data; azimuth and elevation
• D. Azimuth and range data; elevation and range data

Answer: (D)

In a PAR display, two separate sections are used to provide guidance in two planes: horizontal (azimuth) and vertical (elevation). One section shows azimuth data together with range, so you can judge how far off to the left or right you are while knowing your distance to the radar. The other section shows elevation data together with range, so you can judge how high or low you are while still knowing the distance to the radar. Range appears in both sections to keep consistent distance information available in both axes. That’s why the correct description is one section with azimuth and range data and the other with elevation and range data.
