Find SID/STAR: display available SIDs

Even though a SID should not be filed in a flight plan routing, pilots departing from airports with jet and non-jet SIDs would make a better choice of routing if they chose initial waypoints appropriate to the SID. At CYYC, pilots frequently make the wrong choice because they assume the offered routings are appropriate when they are not. Listing SIDs to draw attention to this issue might help to resolve this problem.
