8.2 NAVIGATION’S FUNCTIONS TO A SINGLE WAYPOINT (GOTO)
The following navigation’s functions are available only if a navigation toward a single waypoiny (GOTO) is active :
8.2.1 DIRECTION, DISTANCE, HEIGHT TO THE CURRENT WAYPOINT (GOTO)
BRG 1 (B1) : is the direction to the current Waypoint. Even shown on compass with this icon
and with “follow me" simbol
DST 1 (D1) : is the distance to the current Waypoint
It is possible to set the distance’s unit of measure using the parameter (MAIN SETUP \ n. 16 U-
SP) the same used also for the speed value.
ALT H1 (H1) : is the estimated height of arrival above the current Waypoint.
This height is computed integrating the following info: Altimeter A1, distance to the Waypoint
"DST1" , Waypoint altitude and average glide ratio.
The average glide ratio is continuously update during the glide and stored in the memory during the thermal
flight. To change the average time (seconds) use the parameter (ADVANCED SETUP \ n. 8 EFFA).
The Waypoint’s altitude have to be included in the Waypoint’s name:
o aaaNNN visible on the bottom of the waypoint’s page.
o aaa = 3 alphanumeric characters for the Waypoint’s name.
o NNN = waypoint altitude above sea level, in tens of meters. Note: if the field NNN doesn’t contain three
numbers, then the navigation uses the Altitude field.
8.2.2 NEEDED GLIDE RATIO TO THE CURRENT WAYPOINT (GOTO)
It is the estimated requested glide ratio to reach the current Waypoint.
8.2.3 ARRIVAL HOUR, ARRIVAL TIME TO THE CURRENT WAYPOINT (GOTO)
It is the expected arrival hour "TIM1 (T1)" and the expected arrival time "ETIM1 (E1)" to the current Waypoint
8.2.4 HSI GRAPHIC INDICATION TO THE CURRENT WAYPOINT (GOTO)
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 case of wrong route and up or down the
dashed horizontal line telling us the arrival height with the current gliding ratio.
