BADGER
I've never been a huge fan of mnemonics; but I invented one a couple of weeks back. I've taken to being The Winch Driver out at the Gliding Club. I came up with BADGER as a pre-launch mnemonic.
There are many things that can go wrong with winch launching. I am sure I have not seen all of them; but I have seen a few. That's why I decided to use a mnemonic to make sure that all essential items are checked before starting the 357 Chevrolet motor which pulls the gliders into the air. That motor is mounted on the rear of an old International Harvester truck which carries two steel winch cables coiled on specially made heavy steel drums. You can see one of the drums just behind the white cab. Behind the drum is the winch motor under its metal canopy. At the rear of the winch truck are the wire guides. Each of these is made up of two vertical rollers topped by two plough shares bolted back to back. When the wire reaches the plough shares the glider is usually at an angle of about 45 degrees to the winch.The incoming wire is stopped rising by the mid section of the plough shares which begin to spin very rapidly.
It only takes a minute to haul in the 1,600 metres of cable leading back to the glider, which, on a good day can gain a launch height of 2,000 feet. We lay out the cable by first attaching the ends to two pickets driven into the surface of the airstrip at the Launch Point. Then the winch truck is slowly driven to the far end of the strip with the cable casting off the drums to the rear as the truck moves forward. The drum speed is controlled to prevent the wire being thrown off and getting tangled, by a hand brake mounted in the cab.
Once the truck is at the end of the strip I commence my BADGER check. B is for the truck hand BRAKE. I've seen the truck move backwards when someone forgot to put the wheel chocks in place, so I make doubly sure that the handbrake of the truck is on. I then put the truck in first forward gear, thereby connecting its A, for AXLE, to the gearbox and engine which acts as another measure to keep the winch stationary. D is for the DRUM Brake. It has to be totally released so that the drums are free to haul the cable in. G is for a GROUND check to make sure the wheel chocks are on the ground behind the truck wheels. E is for ENGAGEMENT. Each drum has a driving axle which can be engaged or disengaged. Only one drum axle should be engaged at a time. Having both axles engaged causes all kinds of trouble as both cables get hauled in at once. R is for REPORT. I report by radio: "Launch Point - winch is standing by".
Knowing that I have completed my BADGER check allows me to relax and enjoy the quiet sounds of the bush which surrounds the strip. It is a time for solitude, reflection and contemplation, until I get a call on the radio saying that a glider is hooked up and is ready to be launched. It is then that the Chev motor destroys all sounds of silence until the glider is launched, released and the cable with its drogue attached, is hauled back in and the Chev motor is shut down.
I then swap drum axles and run though BADGER once more before letting the sounds of the bush creep back in.
