NAVIGATION TO START PYLON WAYPOINT
If the current waypoint is a Start Pylon, on the info bar appears the message “START PILON” and 3 minutes
before the start time it appears the message " 3 min to go! " emphasized by a beep.
3 minutes before of the start time some fields of the screen are automatically changed by the instrument
itself.
More: in the screen Glide Plotter, 3 minutes before the start time are changed also the first field from the top
showing the distance from the start “dst1” and the second one from the top where it is shown the tool “er0”,
that indicates in seconds the estimated arrival time to the start, based on the current medium speed referred
to the countdown. E.G: if this field shows “10” means that the pilot twill arrive at the start with a 10 second
late, if it shows “-15”, this means that he will arrive 15 second early (penalty).
Still in this condition, it is disabled the graphic indicator of the HSI.
When expires the time to the start (e.g. =00:00), it appears the message “Gate Opened” followed by a long
beep, advising the pilot that the start gate is opened and it is possible to cross the start line.
When the start time gate is open "Gate Opened" it is allowed to cross the start’s cylinder line (entering or
leaving accordingly of the selected IN / OUT option).
If the start’s pylon cylinder is crossed before the open start gate time, the start pylon distance’s indicator
blinks to show that the pilot is in the wrong side of the start pylon cylinder.
This instrument constantly drives the pilot toward the start line of the “start pylon” till t is properly crossed
from the right side, IF the start time gate is opened; if everything is correct it appears the message: "Start is
OK" and the navigator switches to the next waypoint.
IN = Validation of the start pylon entering in the turn point cylinder.
OUT = Validation of the start pylon leaving the turn point cylinder.
