As far a which is the duty runway, it's the most into wind runway
The above is correct, I would suggest all of you posting on this thread read CAR 166, rather than rely on the AIP.
Are you really certain that the homebuilt really was doing a straight-in? That is not easy to establish, in a legal sense, strange as it may seem.
Having been involved in trying to sort more of this kind of allegation than I care to remember, it is more often than not impossible to reconcile the competing stories of the two pilots involved, without a full tape of the comms., witnesses statements almost always conflict, and even with a tape, you wind up with some wide interpretations, having related the timing to aircraft estimated position.
The types of aircraft are not relevant, same rules apply to all, especially "Regional" airlines.
In balance, the aircraft landing into wind probably had priority.
Who was demanding who's ARN, and no, you don't have to reveal it (identify yourself) to other than an authorized person.
Tootle pip!!
