NAVIGATION FUNCTIONS TO A SINGLE WAYPOINT (GOTO)
The following navigation functions are available only if navigation toward a single waypoint (GOTO) is active:
8.2.1
DIRECTION, DISTANCE & HEIGHT TO THE CURRENT WAYPOINT
BRG 1 (B1): is the direction to the current Waypoint; it is shown on the compass with the icon
and the “follow me" symbol
.
DST 1 (D1): is the distance to the current Waypoint.
It can be displayed in km or in mi; go to MENU \ MAIN SETUP \ n.15 U-DS.
ALT H1 (H1): is the estimated height of arrival to the current Waypoint.
This height is computed integrating the following information: A1 Altimeter, distance to the
Waypoint "DST1”, Waypoint altitude and average glide ratio.
The average glide ratio is continuously updated during the glide and stored in the memory during the thermal
flight. To change the average time (in seconds), use the ADVANCED SETUP \ n. 9 EFFA parameter.
8.2.2
COMPASS TO THE CURRENT WAYPOINT
There are two types of “Compass” instruments: a circular and linear compass and two models of the linear one.
All of them will show you the direction to the current waypoint displayed with the icon.
8.2.3
REQUIRED GLIDE RATIO TO THE CURRENT WAYPOINT
It is the estimated required glide ratio to reach the current Waypoint.
8.2.4
ARRIVAL HOUR, ARRIVAL TIME TO THE CURRENT WAYPOINT
It is the expected arrival hour "TIM1 (T1)" and the expected arrival time "ETIM1 (E1)" to the current Waypoint
8.2.5
HSI GRAPHIC INDICATION TO THE CURRENT WAYPOINT
HSI is a graphical navigation tool made by two dashed lines that intersect each other,
indicating the current WPT and its real height. Flying towards the center of the WPT cylinder,
the airplane icon moves right or left of the dashed vertical line in reference to the route and up
or down of the dashed horizontal line telling us whether, with the current glide ratio, we will
arrive above or below the waypoint.
