In this case, aircraft alters course by 60 degrees and flies the new course, for say, one minute. After one minute the pilot alters course by 120 degrees and flies this course for one minute and thereafter gets onto the original course in this process. The aircraft would have lost one minute. Other dog leg procedures involve alteration of original course by 30 and 45 degrees.
An intentional, temporary moving away from the track and returning to it later on with a view to either lose time or avoid bad weather or an obstruction. The two common methods of doglegs are to alter one's course by 30°/45° and fly for a fixed period of time. Thereafter, the pilot can alter the aircraft's course by double the original change (i.e., by 60°/90°) and fly this leg for the same period of time. At the end of this period, the original course is resumed, assuming there is no wind.
