Ten Rotary Commandments
Found this in an old book on the history of helicopters. It was credited to the RAF in the Far East decades ago. Most of us would have seen something similar over the years, but it's probably worth another run.
“THE TEN COMMANDMENTS OF HELICOPTER FLYING”
- He who inspecteth not his aircraft gives his angels cause to concern him.
- Thou shalt not become airborne without first ascertaining the level of thy propellant.
- Let infinite discretion govern thy movement near the ground, for thy area of destruction is vast.
- The rotor RPM is thy staff of life, without it thou shalt surely perish.
- Thou shalt maintain thy speed between ten and four hundred feet, lest the earth rise and smite thee.
- Thou shalt not make a trial of thy centre of gravity, lest thou dash thy foot against a stone.
- Thou shalt not let thy confidence exceed thy ability, for broad is the way to destruction.
- He that doeth his approach and alloweth the wind to turn behind him shall surely make restitution.
- He who alloweth his tail rotor to catch in the thorns curseth his children and his children’s children.
- Observe thou this parable, lest on the morrow thy friends mourn thee:
Safety dwells with the safest man
Who flies his bird as safe as he can.
