Helicopter
A helicopter is an aircraft which is lifted and propelled by one or
more horizontal rotors. Helicopters are classified as rotary-wing aircraft to
distinguish them from conventional fixed-wing aircraft. The word helicopter is derived
from the Greek words helix (spiral) and pteron (wing). The first single-rotor,
fully-controllable helicopter to enter large full-scale production was made by
Igor Sikorsky in 1942.
Compared to conventional fixed-wing aircraft, helicopters are much more
complex, more expensive to buy and operate, relatively slow, have shorter
range and restricted payload. The compensating advantage is maneuverability:
helicopters can hover in place, reverse, and above all take off and land vertically.
Subject only to refueling facilities and load/altitude limitations, a helicopter can
travel to any location, and land anywhere with enough space (approximately
twice the area of the rotor disk).
Compared to other vertical lift aircraft like tiltrotors (V-22 Osprey for example)
and vectored thrust airplanes (also known as VT-OL jets, standing for Vertical
Take-Off & Landing) (AV-8 Harrier for example), helicopters are very efficient,
carrying more than twice the payload, consuming less fuel in hover and costing
considerably less to buy and operate. However these other configurations have
considerably more cruise speed than a helicopter (270 km/h for a helicopter,
460 km/h for a tiltrotor, 900+ km/h for a vectored thrust airplane).

Flight training is a course of study used when learning to pilot an aircraft.
Although there are various types of aircraft, many of the principles of piloting them
have common techniques, especially those aircraft which are heavier than air types.
All training courses consist of some combination of theoretical learning conducted on the
ground, and practical exercises conducted in the air. Initial training is often conducted
in specialised training aircraft, which are designed for benign handling characteristics
and lower costs compared to the aircraft which the pilot concerned is ultimately aiming to
fly. Flight simulators are also used to train pilots in many procedures, at much lower cost
and risk than actual flying.
In basic training, the following fundamentals of safe
flying are covered for almost all aircraft (with a few exceptions for the smallest ultralights
missing some features): - Principles of Flight
- Flight Regulations
-
Meteorology
- Navigation
- Radio Communications
- Flight Instruments
- Human Factors
- Medical Certification
For powered aircraft: - Airframes, Engines and Systems
