Chapter 5. Flight Analysis
35
Comp ID
Contest ID from of the glider
Total Flight Time
Elapsed time between the roll time and landing
time. Useful for determining the time for a flight
logbook entry
Number of Fixes
The number of position fixes in the IGC file.
Task Status
Tells if the task was successfully completed.
“Completed Task” means a valid start was made,
all turnpoints were visited in the correct order, and
a valid finish was made. Otherwise, this value is
“Incomplete”.
Distance
The task distance: the sum of the straight-line
distance between each task leg, minus the start and
finish cylinder radii if they are defined.
Time On Course
The time difference between the start time and
finish time
Speed
Average speed over the entire task calculated by
dividing the task distance by the time on course
Roll Time
Time at which the glider reached takeoff speed.
Start Time
Glider start time. This could be the last exit out the
side of a start cylinder, out the top of a start
cylinder, or the last crossing of a start line. The
start time is calculated by linear interpolation
between the first fix after the start and the
preceding fix.
Finish Time
Task finish time. This could be the entry into the
side of a finish cylinder, descending into the top
finish cylinder, or the crossing of a finish line. As
with start times, finish time is calculated by linear
interpolation between the last fix before the finish
and the next fix.
Landing Time
Time the glider dropped below flying speed and
landed.
Turnpoints
Achieved
These are the ID’s of the turnpoints successfully
achieved in the correct order. To achieve a
turnpoint, at least one fix must be within the circle
defined by the turnpoint radius from Step 1
(above). The turnpoint is still be considered
achieved if there is at least one fix in a circle
defined by the outer radius, but a warning is be
displayed.
Notes:
Information and warnings about the analysis are
displayed in the Notes section.
Troubleshooting
Occasionally the analysis calculates that the task was incomplete, when clearly the task
was flown and completed correctly. In this event, check the following carefully.
?? Display the flight with the task overlaid to verify that the task’s turnpoints were
specified correctly, in the correct order. Make sure that at least one fix is inside each
turnpoint’s outer radius.
?? If using start or finish lines, make sure the lines were crossed in the correct direction.
?? Using the Back button, go back to steps 2 and 3 (above) and verify that your start
gate, finish gate, and turnpoints were set up correctly.
?? Check the calculated start time and see where that fix appears in relation to the start
cylinder or start line. Check the pressure altitude against the top of the start cylinder.
