Fact is that the ATR is a more flexible machine for PNG long term now that Bombardier have stopped manufacturing the DHC8-200s.
Vicking Twin Otters may even be a plausible solution if PX want to continue to go to places such as Chimbu. It would be a good spinner in terms of training, financial return and satisfying the grass roots people in the rural under serviced remote locations. Air Niugini is PNGs national airline owned 100% by the citizens of PNG.
Salesmen talk actually opened up Chimbu to PX with the DHC7 🇵🇬🇵🇬🇵🇬🇵🇬
