I'm with you on this one Capt Claret. Had a similar thing the other day. Not only did a 206 (same mob as the 402) cut in on us during the final segment of an instrument approach. But took forever to vacate the runway, causing us to go around!
Then on departure, we waited TEN MINUTES, burning many lbs of Jet A1,
at the holding point as a BN2, 206, 310 and every other machine in the NT joined downwind. Not one extended downwind just a little to let us out. When asked, "No sorry, turning close base now".
Before that a 402 cut underneath us making us do a really long downwind. To make me even happier, a 210 asked could he go number 2 to the 402, seeing as how we were on such a long downwind. Yeah right!
To the guys with the Red and Yellow aircraft, how about a little courtesy?
