"Strip width" of course refers to an obstacle-free area about a runway which for certification to handle P121 operations, is 150m. The runway, as opposed to "strip width" still requires a minimum of 45m (or 30m if you're giving one to the Director's Mrs
)
Even taking into account strip width, how long is Manapouri's runway, so that it could handle jet aircraft? I read in the media somewhere that it had been extended from 1622 meters ( which sounded too long) - 2000 meters in length (that's longer than Dunedin at 1900 meters..). I also read somewhere that it had been extended by 600 meters, from what length I wasn't quite sure.. Anyone know the correct specs of the new runway?
