It's the Dash 8 Q400 they are looking at,rumour is that they want 2 by the end of the year to operate over the F100 routes. Aparently Lihir Gold and Oilsearch are also very interested because the aircraft has the legs to go direct to Brisbane from there sites at pritty much jet speeds. Obviously the payload would be sumwhat reduced down to about 50 pax. Crewing and maintaining the machines will be the biggest headache. PX can't crew all the Dash 8's they already have.
