As those of you not in Sydney and surrounds may have heard, we've had a few of a bushfire issues lately. Yesterday, we had intended to fly from Warnervale - north of Sydney - to Jaspers Brush - in the south - for the EMT course that the kind folk were running there. Unfortunately, prior to the entry to the western VFR lane at Brooklyn bridge, we hit a solid wall of smoke trapped in an inversion layer at about 1,500'. Yes, we were clear of it, but there was zero ground reference for navigation and zero opportunity to pick a landing spot should things go quiet. We shot over to the coast, but the smoke went far out to sea.
Figuring that it would dissipate as the morning progressed, we went back to base for a coffee before having a second go. Second time was even thicker. At the coast, we tried to descend on the basis that from 500', we'd have adequate visibility, but apart from choking as we went into the smoke layer, we also started to loose any horizon. Didn't hang around there, admitted defeat, and went home.
This morning, I was up at the Brooklyn bridge again, but this time on a slightly more earth-bound conveyance, and this is what it looked like. For those of you who don't know the area, this is about half way across the bridge, and there is a dirty great big mountain at the far end of it...
I hope the Emergency Maneuvers training went well, because the only emergency maneuver we go to practice was the 'Turn and Run'. Ah well, live to fight another day.
