BLIP Track Average

This application will determine if a given task can be completed, using the RASP forecast data as a guide.

To use the application, perform the following:

(1) Select the day you're thinking of flying.
(2) Select the proposed time of departure.
(3) Select a glider (your own type) - generally the Standard Cirrus (StdCirrus) is good at 36:1 glide ratio
(4) Select if you're using ballast or not.
(5) Select estimated circling sink rate (in still air - 2.0 down is a good default).
(6) Select thermal multiplier (1.0 is a good default).
(7) Add your turn points for your task in BGA three-letter codes. Note that you need a 'start' and at least one other (TP1). You do not need to fill all the boxes in.

(8) Press the 'GO' button.

Notes:
(a) The actual date is printed on the results.
(b) If you want the results in a separate window, 'check' the 'NEW WINDOW' check box above the 'GO' button.
(c) Not sure what a turn point is? A full list of BGA turpoints can be found here.

Based on original script by Paul Scorer. With additions by Darren Hatcher.
