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!

EMS/Air Ambulance

Patients just being moved from one hospital to another do not qualify for any exemptions for saving life, but special provisions may apply for duty hours.
A Helicopter Emergency Medical Service (HEMS) flight is for immediate and rapid transportation of medical personnel, supplies (equipment, blood, organs, drugs) or ill or injured persons and anyone else directly involved. An approval is required. The purpose of a casevac is to give immediate assistance to sick or injured people in life threatening circumstances, typically from the scene of an accident.
Otherwise, there are two types of ambulance flight, Intensive Care Transport (ICT) and Ambulance Taxi Transport (ATT). Both are usually planned in advance, meaning that there’s not so much of a rush. Any police observers or medical attendants should be able to monitor and assist the patient during the flight and inform you of any problems.
Whatever you get involved in, the following should generally be avoided:
.
Anyone with previous or present signs or symptoms suggesting epilepsy or any other form of fit.

.
Unconscious patients, unless in-flight attention is available.

.
Patients with severe haemorrhagic types of injury, unless in-flight attention is available.

.
Abdominal or chest injuries if altitude changes of up to 1500 feet are likely to be involved.
