Wamena Elevation - GPS vs Altimeter Set to Low Elevation Air

The DGCA is updating airport elevations using survey-grade GPS units. Pilots arriving at Wamena with an altimeter setting from a low-elevation airport (Sentani, Timika, Nabire, Merauke) will notice a significant difference in elevation (altimeter will show closer to 5100’ at Wamena). This is mainly due to the errors associated with a pressure altimeter in higher-than-standard temperatures. For more information about this indicated vs true altitude error, see FAA AC 00-6B 5.4.1 “Altitude”, John S Denker “How It Flies” 20.2.4 <> and Mike Borgelt’s article at
