Not that much use for a 737 domestically in PNG, I would have thought.
Most places too short or narrow, Tokua full of holes, Gurney, Manus, Nazab ok, but movements restricted by NAC to minimise Runway and Tarmac damage.
Most places have had U/S NAVAIDS for many, many, many months meaning visual or GPS approaches only.
Maybe Travel Air going International. 😳
