What is a cursor?

• A. An electrically generated strobe that normally originates in the center of the CRT
• B. A mechanical pointer for range scaling
• C. A fixed crosshair overlay on the PPI
• D. A scrolling text indicator at the bottom of the display

Answer: (A)

A cursor on a plan-position indicator is the electronically generated marker that designates a reference location on the radar display. It’s produced by a strobe circuit and normally starts at the center of the CRT, so you can move it to any point on the screen to indicate the target’s position for range and azimuth measurements. This marker is moved with controls, unlike a fixed crosshair or a scrolling text indicator. It’s not a mechanical pointer, and it isn’t a static overlay, but a movable electronic cue used to pinpoint positions on the display.
