a. A SOARING PERFORMANCE may be claimed for gain of height, absolute altitude, duration, distance, and speed.
b. A SOARING PERFORMANCE may be claimed from any flight that meets the requirements of proof for that performance. (AL8)
c. A DECLARATION is required except where specifically not required in the rules.
d. WAY POINTS must be declared and used in the sequence declared except where specifically not required in the rules.
1.4.2 Altitude, gain of height, and duration performances.
No DECLARATION is required.
a. ABSOLUTE ALTITUDE
A SOARING PERFORMANCE measured for maximum altitude achieved. An absolute altitude performance is valid only if preceded by a GAIN OF HEIGHT of at least 5000 metres.
b. GAIN OF HEIGHT
A SOARING PERFORMANCE measured for GAIN OF HEIGHT.
c. DURATION
A SOARING PERFORMANCE measured for DURATION.
1.4.3 Free distance performances for records only.
The WAY POINT(S) of free distance record flight performances may be declared postflight. Free distance courses may be claimed in conjunction with any other flight course in 1.4.4, 1.4.5 and 1.4.6 using declared WAY POINT(S) if desired. The free distance record types are: (AL8)
a. FREE DISTANCE
A flight from a START POINT to a FINISH POINT with no TURN POINTS.
b. FREE OUT AND RETURN DISTANCE
A CLOSED COURSE flight having one TURN POINT.
c. FREE DISTANCE USING UP TO THREE TURN POINTS
A flight from a START POINT via up to three TURN POINTS to a FINISH POINT. The TURN POINTS must be at least 10 kilometres apart and may be claimed only once.
d. FREE DISTANCE AROUND A TRIANGLE
(i) A CLOSED COURSE flight via three TURN POINTS independent of the position of the START/FINISH POINT. The OFFICIAL DISTANCE is given by the sum of the LEGS of the triangle formed by the TURN POINTS.
(ii) A CLOSED COURSE flight via two TURN POINTS.
(iii) For record flights of 750 kilometres or more, no LEG of the triangle may have a length of less than 25% or more than 45% of the OFFICIAL DISTANCE. For shorter record flights, no LEG may have a length of less than 28% of the OFFICIAL DISTANCE.
Note that the start and finish points are not turn points unless specifically declared as such (this applies to 1.4.4b also).
1.4.4 Distance performances for badges and records
The following COURSES may be used only for distance flights:
a. STRAIGHT DISTANCE TO A GOAL
A flight from a START POINT to a declared FINISH POINT with no TURN POINTS.
b. DISTANCE USING UP TO THREE TURN POINTS
A declared flight from a START POINT via up to three TURN POINTS to a FINISH POINT. If the FINISH POINT is the landing place it need not be declared. The TURN POINTS must be at least 10 kilometres apart and may be claimed once, in any sequence, or not at all.
1.4.5 Distance performance for badges only
STRAIGHT DISTANCE
A flight from a START POINT to a FINISH POINT with no TURN POINTS. No WAY POINT DECLARATION is required unless a START POINT other than the RELEASE POINT is used or the FINISH POINT is also to be a GOAL.
1.4.6 Distance and speed performances for badges and records
The following COURSES may be used to claim distance and/or speed performances.
a. OUT AND RETURN FLIGHT
A CLOSED COURSE flight having one TURN POINT.
b. TRIANGLE FLIGHT
(i) A CLOSED COURSE flight via three TURN POINTS independent of the position of the START/FINISH POINT. The OFFICIAL DISTANCE is given by the sum of the LEGS of the triangle formed by the TURN POINTS.
The minimum OFFICIAL DISTANCE for this type of course is 300 kilometres.
(ii) A CLOSED COURSE flight via two TURN POINTS.
(iii) For records only, the restrictions on triangle geometry noted in 1.4.3d (iii) also apply.
1.4.7 Loss of height - alternate calculation for distance flights
A distance flight (1.4 4, href="sc3.1.4#5">1.4.5 and 1.4.6) starting as defined in 1.1.7b (a declared START POINT) may be claimed where the LOSS OF HEIGHT (1.2.7) is measured from the release height to the elevation of the finish point.
The release point is not the start of the course in this case.
