Since dr dre didn’t respond to the original question, my response would be to use old school methods if VNAV was not available. You can approximate the descent point based on the 3-in-1 method or the metres button. eg From FL340 to sea level, 3x34=102NM, or FL340=10363m (103.63NM).
But if VNAV was available, what distance from Penang do you predict for the VNAV Top Of Descent Point into Penang if:
Cruise at FL340/294CAS,
Descent speed 268CAS,
Nil wind,
No STAR or approach loaded.
