I sat my SCPL Flight Planning Exam around 1979. Are you saying they are STILL using the 727 as the example?
Did my ATPL theory back in mid '92 and the Flight Planning was based on the 727. Found it fairly straightforward, once I had it mastered, so to speak.
The actual exam was, most thankfully, almost indentical to one of the practice exams we had been given!
Somewhat surprised to read that they are still using the 727 though!
