A7.3 Flight time
The take off time is automatically recorded and the flight time starts as soon as the speed over the ground, or through
the air, reaches a reasonable flight speed. The flight time can be displayed in the user field
Flighttime
. The 5030 will
also automatically recognize the end of the flight. In basic settings Menu>Basic Settings>Recording Mode
you can
choose between manual and automatic for the ending of flight recordings. For more details see section C2 -Flight
Memory and Flight Analysis.
A7.4 Track and Bearing
The
Track
is defined as the route of the glider over the ground and can be displayed in the user field
Track
. Bearing
is the compass heading to a desired point and can be shown in the user field
Bearing
. Geographic true North is
always 0 or 360 degrees (East 90,
South 180, West 270 degrees). The bearing is the direction to a specific
destination or waypoint from the glider. A
Track log
results from recording different position points at regular
intervals during a flight.
A7.5 Distances
A7.5.1 Distance to Waypoint
The horizontal distance to a waypoint is can be displayed in the user field
Dist to WP
.
The distance is displayed if
either the destination has been switched to automatically (using the route function), or chosen manually with the
Goto
function. For distances under 10 km, the resolution is 10 m, if farther it is 0.1 km. Please read section B7 Goto
Function. The distance to waypoint is always measured to the
waypoint
and not to the edge of the cylinder around
the waypoint.
A7.5.2 Distance to last thermal
This function helps the pilot relocate thermals that are lost when searching for better lift. The user field
Dist to ^
will
show the distance to your last thermal over 200 ft/min. A small up-arrow in the double ring of the compass rose
shows the direction to the last thermal. If this arrow is displayed at the top in the ring, then you are flying towards the
thermal. However, if the arrow is below in the compass rose, you are going away from the thermal.
A7.5.3 Distance to Goal
The remaining distance to goal or the end of a route around the balance of the route can be displayed in the user field
Dis t Goal
A7.5.3 Distance to restricted airspace
It is possible to enter restricted airspace/restricted areas (referred to as CTRs) in the 5030. CTRs will be shown on
the real-time map and can be polygons, circles or polygons with arc sections. The distance to the nearest CTR can
be displayed with the user field
Dist t Ctr.
A7.5.4 Distance to take-off
The distance to the “take-off” point can be shown in the user field
Dist Tkoff.
The take-off point is defined as the
position where the instrument declared the beginning of the flight (more than 10km/h TAS or GPS speed for 5s).
A7.6 Glide Ratio (L/D Ratio)
By definition, the glide ratio is calculated by taking the horizontal distance traveled and dividing it by the height lost.
Attainable glide ratios in calm air for the following glider types:
Normal Paraglider
High Performance
Paraglider
Normal Hang Glider
High Performance
Hang Glider
Rigid Wing Hang
Glider
5-7
7+
8-10
11-14
15+
The following types of glide ratio can be selected as a user-selectable field.
Glide ratio through the air:
L/D air
= TAS / Sink - True airspeed divided by sink
Glide ratio over the ground:
L/D gnd
= GS/Sink - Ground speed divided by sink
