Guest Cralis Posted October 21, 2008 Share Posted October 21, 2008 Hi guys, I took my frequency scanner to Caboolture on Sunday to listen to what was happening and see what is meant by building a mental picture of where aircraft are based on their calls. Quite interesting... I'm battling with '5 miles North West of the field'. I'm thinking in my head - how did he know that!? Look at the compass, and work out the reciprical value, or something? Need to brush up on my quick maths! :) Anyways, I saw a powered glider doing his downwind pass. Behind him, not very far back was a normal glider. I heard the powered guy reporting that he was on downwind. Thene there was a 'hiss' on the radio as if someone was about to speak - lasting maybe 4 seconds, then nothing... The powered guy entered left base, and reported. Glider had closed on him a bit. Then the glider entered his base turn, and again.. a hissss.... and nothing. By now, I was watching intensly, as it seemed the glider was catching the motorised glider. Motorised guy turned and reported for finals. Then, about 5 seconds later, this hissss... as the glider followed him... They were now at a distance that I thought the powered guy may have been towing... but surely not! I watched as the powered guy landed... and timed it.. and measured that 3 seconds later, the glider landed behind him - same runway. There was no tether! :ah_oh: Firstly, if this is normal - disregard. But I just thought that it looked like an accident in the making. The glider seemed WAY too close. 3 seconds.. count it ... is pretty close, no? And he was cathing all the time... OK, maybe the slowing speed makes the time gap remain the same, but the distance reduce... but... it seemed fishy. Also, the fact that I never once heard the glider report his position... strange. So, as a novice, I can guess at the fault: The gliders mic wasn't working. Was he perhaps broadcasting, but as there was an issue with his radio, no-one heard him. Especially the powered glider ahead of him. He may have had no idea he had a glider behind him, and I guess a glider can't do a go-around - but without the powered glider knowing there was someone so close behinf him - he was just cruising in as normal. Or, perhaps the powered guy knew about it, and maybe this is what you do when you know another aircraft has a comms problem? Fly close? I saw the glider had his spoilers up from quite far out... so he was trying to go slow... but as I say, it seemed to get closer and closer... dangerously so. Any ideas? Seems srange eh? My second question would be what IF the radios were working. As the powered guy seemed to be going slower (somehow), could the glider warn him that he is a glider, and to hurry up - which would then maybe get the powered guy to abort, climb out and go around for another landing? The glider really has no option except to slow down. But he can't go-around... he's basically commited to the landing. What happens in this case?
