Basic Navigation Indicators<br />

Basic Navigation<br />

The basic navigation mode provides steering cues to the next route steer point. In<br />

addition to the basic HUD scales, navigation mode includes the following<br />

indicators:<br />

• The radar altitude scale appears on the right side, providing an exact, radardetermined<br />

display of the aircraft’s Altitude above Ground Level (AGL). A caret<br />

moves along the scale indicating the current altitude while a digital readout<br />

(followed by the letter “R”) appears in the lower-right corner of the HUD.<br />

• Information about the next steer point is presented below the radar altitude<br />

readout. The first number indicates the ID of the next steer point. The number<br />

following the “/” indicates the distance (in nautical miles) to the next steer<br />

point.<br />

• The time-to-go indicator, located beneath the distance indicator, shows the<br />

time to the next steer point. The number following the “/” indicates whether<br />

the aircraft will arrive early or late against the assigned time to reach that steer<br />

point. A negative number indicates a late arrival.<br />

• The current time is displayed beneath the time-to-go indicator.<br />

• The command heading bug indicator moves along the lower edge of the<br />

heading tape, providing a steering cue to the next steer point.<br />

• The destination index moves within the entire HUD, pointing to the next<br />

steer point.<br />

• The text in the lower-left corner of the HUD indicates the current autopilot<br />

mode.<br />
