Do not push the envelope and remain easy on the controls
Avoid abrupt control inputs or accelerated manoeuvres, particularly at high speed.
These produce high fatigue loads in the dynamic components and could cause a
premature and catastrophic failure of a critical component.
Strobe lights ON – for your own and other’s safety
Turn the strobe lights (if installed) ON before starting the engine and leave it on until
the rotor stops turning. The strobe lights provide a warning to ground personnel.
Leaving them on in flight is also advisable since the helicopter may be difficult for other
aircraft to see.
Rotors can be extremely dangerous
Never attempt to start the engine until the area around the rotor is completely clear of
any persons or objects. Do not start the engine while standing beside the helicopter.
Be sure ground personnel or onlookers don't walk into the main rotor. Mind the spinning
rotor when hovering close to obstructions or persons. It is advisable to maintain at least
one rotor diameter distance from obstructions or persons when hovering with spinning
rotor. A fast turning rotor is almost invisible, but may contain enough energy to kill a
person.
Never let go of the control stick and make sure the rotor blades spin down in
level/horizontal attitude until the rotor is at a complete stop. Wind or negligent behavior
on the control stick may cause the blades to flap dangerously low and hit control stops,
stabilizer, or people.
Power lines and cables are deadly
Flying into wires, cables, and other objects is by far the number one cause of fatal
accidents in rotary wing aircraft. Pilots must constantly be on the alert for this very real
hazard.
Ø
Watch for the towers ; you will not see the wires in time.
Ø
Fly directly over the towers when crossing power lines.
Ø
Constantly scan the higher terrain on either side of your flight path for towers
Ø
Always maintain at least 500 feet AGL except during take-off and landing.
