10.4 NAVIGATION TO STANDARD WAYPOINT
If the current Waypoint is not set as a start
pylon, the navigation is managed in ‘standard
cylinder mode’ and the Digifly Air will drive you
providing constant info about your posistion,
distance, direction, required glide ratio and
expected arrival height above the current
Waypoint cylinder and to the arrival Waypoint
cylinder.
When you arrive near the Waypoint cylinder
the flight recorder rate is automatically set to
one data point per second. The parameter “NEAR” can be modified from the page Waypoint’s edit.
Cylinder validation: entering in a cylinder the Digifly air will alert you with a sound and will appear the message
“WPOK” or the message “TASK FINISHED” if it is the arrival Waypoint then flight recorder rate returns to the
setup value (MAIN SETUP \ n. 5 RECR).
If the navigation is activated the following functions are available :
10.4.1 DIRECTION, DISTANCE AND HEIGHT over CURRENT WAYPOINT
BRG 1 (B1) Shows direction to current cylinder waypoint along the optimized route. Its shown
with this icon
on compass and with icon "follow me"
DST 1 (D1) : ) Shows distance to current cylinder waypoint along the optimized route.
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) : ) Shows estimeted arrival height to current cylinder waypoint along the optimized
route.
this height is calculated as follows: Alti A1, distance to current cylinder waypoint DST 1, height
current Waypoint and average efficiency.
Average efficiency is updated in real time while gliding and stored while thermaling , to change value of refresh
(in seconds) modify parameter (ADVANCED SETUP \ n. 8 EFFA).
