Another example at the airfield from which I fly! I went out this morning fully intending to do just a circuit or two. As it turned out, a flat battery put the kibosh on that. However, as usual I had my airband receiver switched on during my drive, I heard one aeroplane make a couple of totally garble calls. At the airfield there was a PA38 on the terminal apron and a Jabiru taxying out. The Jab called taxying to holding point with no mention of which holding point. The PA28 departed without any calls that I heard. There was also a light twin, Duchess maybe, that arrived on an Rnav approach (I presume) overflew before coming round and landing on 09, he then rolled through to the end, turned around and took off on 27. I didn’t hear any calls again! I’m not saying there was danger but there certainly was the potential for it!
