pressure altitude in hundreds of feet. The Altitude option
choice is shown in the upper left corner of the screen.
Relative altitudes are shown with a “+” or “-”, while
absolute altitudes are shown as just a number.
Filter
An altitude filter allows targets that are outside of a

The current mode is shown in the upper left corner of the

filtering is active.
