Is a helicopter harder to fly than an
airplane?
Certainly not. Anyone who can ride a unicycle, walk the dog
with his yo-yo, and balance a broomstick in the palm of his hand
simultaneously should be able to fly one with no problem. After
15-20 years of practice, it begins to come as second nature.
How much does it cost to learn to fly a
helicopter?
All the money you have and all you will ever make.
I've seen "Blue Thunder" and I'm just dying to know. Can
a helicopter really do a loop?
A kitchen table can do a loop, if properly piloted. Many
helicopters, including the humble Bell 47, have been looped. The
secret, as in any loop, is not to pull too many or too few Gs.
Negative G going over the top can be particularly disastrous, since
it will cause the helicopter to fall through its own rotor system.
Not recommended for long life and happy aviating.
Why can't helicopters go any faster?
Anytime a helicopter begins moving forward, at least one of
its rotor blades is always heading back the direction the helicopter
just came from. In forward flight, the speed of the oncoming wind is
added to the rotational speed of the blade moving in the same
direction as the helicopter, and subtracted from the speed of the
blade going away. This means more lift on the advancing side of the
rotor disc than on the retreating side; at some point, depending on
the helicopter, the lift on the advancing side will exceed the lift
on the retreating side so drastically that the helicopter would roll
on its back.
What does the little propeller on the back do?
It's used to offset the torque created by the main rotor, and
it works by shooting a fan of wind out to the side. The tail rotor
is connected to the helicopter's rudder or anti torque pedals, and
are also used to control the helicopter about the yaw axis.
Helicopter pilots don't have to input pedal movements in turns,
however, since there is no adverse yaw in a spinning rotor system.
What is this"Dead Man's Curve" I keep hearing so much
about?
This is merely a cute nickname for something in the
helicopter handbook called a Height Velocity Diagram. The diagram is
a chart depicting the regions in which a helicopter shouldn't be
operated for sustained periods of time because if the engine should
fail, the pilot probably won't be able to complete a safe
autorotation landing. Example: five feet above the ground and 120
knots; 75 feet above the ground and zero knots. In either case, the
manufacturers figure the helicopter would be on the ground before
the pilot had time to figure out what happened and take corrective
action.
Do jet helicopters actually use jet thrust for
forward speed?
Not strictly speaking. On some helicopters, such as the Huey,
there is a certain amount of thrust from the tailpipe. It can cause
the helicopter to drift somewhat while hovering, but it doesn't
contribute in any significant way to the helicopter's propulsion.
Are homebuilt helicopters safe?
Nobody has any guarantees, of course, when they get into any
aircraft. These helicopters have been flying successfully for some
time, and are nifty little machines. Considering anybody can have a
"Bad" day, just hope that the builder of the machine you are going
to fly had no "Bad" days during the construction of the helicopter.
Also, hopefully the builder had no "extra" parts when it was
completed!!!!!
What is "settling with power" ?
Settling with power is what happens when a very slow-flying
helicopter begins to sink into the disturbed air directly under its
rotor system. Once the rotor blades hit the agitated air, they begin
losing lift; the pilots instinctive reaction usually is to add power
to try and arrest his sink rate. When he does this, however, he only
creates a greater volume of unstable air under himself, which causes
the helicopter to sink even faster and faster. There are two ways to
fly out of settling with power: One, gain forward airspeed and fly
out of the column of disturbed air, and Two, reduce power and allow
the helicopter to drop out the bottom of the air column. The latter
procedure is not recommended especially at low altitude.
Okay, you've got the fever. You have mortgaged your life
and got a commercial airplane license and a add-on commercial
helicopter rating . Now, can you get a job?
Good Luck. : ) It's not that it cant be done, but there are
several problems. Number one, ex-military pilots as a rule get first
crack at most civilian flying jobs. This is because most of them
have 500-1000 turbine helicopter hours at a minimum and a instrument
rating. Second choice curiously enough, seems to go to the pilots
who are relatively low time (300-500 hours), but who learned to fly
helicopters from scratch. According to industry sources, A person
who learns exclusively in the helicopter, no fixed wing time, has
nothing to unlearn . High time fixed wing pilots sometimes lapse
into their "Bad" habits at the worst possible time.
Just
remember, Helicopters don't fly, they beat the air into submission!!
