Vertical reference skills are needed, as you must place your torch right next to a second fuel/gel drum for quick and easy turnarounds. In some cases, such as backburning to a seismic line, you will need to be quite accurate, as when igniting the very edge of the upwind side of a given cut line (ensure your mirror(s) are properly adjusted). You must be able to clearly see where the flaming fuel/gel is contacting the ground. Beware of violent vertical up and down drafts close to a large flame front. In an updraft, keep the disc loaded for the inevitable downdraft that will follow, in which case you should be light enough to allow a safe margin of available power to prevent contact of your torch with the treetops. For this reason, 400-450 lbs of fuel seems to work well with a LongRanger. As with any fire, be prepared for moderate turbulence and rapid reductions in visibility, keep your doors on, and your windows closed, as small bits of burning ash and debris can enter the cabin. Be wary of pinstriping, or lettering, etc. that is not painted on. Activate the torch in spurts from 3-5 seconds, then off for 2 seconds, then on, etc. This prevents pump, and output nozzles, from overheating, and will reduce the chances of the circuit breaker popping. Disarm the circuit breaker during the ferry to or from the burn area, and when the equipment is active, try to fly only over that location, or you might start another fire somewhere else. Carry your Bambi Bucket with you, so if it all goes pear-shaped, you can put the fire out you just started!
