Why are human factors important in aviation?

In aviation, human factors is dedicated to better understanding how humans can most safely and efficiently be integrated with the technology. That understanding is then translated into design, training, policies, or procedures to help humans perform better.

What is the helicopter approach?

An approach is the transition from traffic pattern altitude to either a hover or to the surface. The approach should terminate at the hover altitude with the rate of descent and groundspeed reaching zero at the same time. Approaches are categorized according to the angle of descent as normal, steep, or shallow.

What is human factors in aviation maintenance?

Aviation maintenance human factors programs focus on the people who perform the work and address physical, physiological, psychological, and psychosocial factors. [Figure 14-11] It must focus on individuals, their physical capabilities, and the factors that affect them.

What are helicopters inspired by?

All About Igor Sikorsky and Other Early Flight Pioneers During the mid-1500s, Italian inventor and artist Leonardo Da Vinci (1452–1519) made drawings of an ornithopter flying machine, a fantastical machine that might have flapped its wings like a bird and that some experts say inspired the modern helicopter.

How do human factors affect human performance?

The design of artefacts such as equipment, tools and procedures, as well as tasks, jobs and work systems, affect human performance in different ways. This acknowledges the influence of factors outside of humans on human performance, and therefore helps to explain it.

At what angle should you approach a helicopter?

A shallow approach is considered a glide slope of 5 deg., “generally, for almost any helicopter.” A normal approach is 10 deg. and a steep one is 15 deg. or more. The difficulty and sensitivity to errors each increases with the angle. There are several common problems or common mistakes in approaches, he said.

How do you approach a helicopter EMS uphill or downhill?

Always approach & depart helicopter from the sides (3 or 9 o’clock), never around the tail rotor. from the downhill side, never from the uphill side. Maintain radio contact with the pilot until the aircraft has landed.

Were helicopters used in ww2?

Sikorsky R-4, the world’s first production helicopter, which served U.S. and British armed forces in World War II. An experimental version of the aircraft first flew in 1942.

What is the reason why helicopters are used in warfare?

In larger militaries, these helicopters are often purpose-built for military operations, but commercially available aircraft are also used. The benefit of using helicopters for these operations is that personnel and cargo can be moved to and from locations without requiring a runway for takeoffs and landings.

What are the risks of helicopter accidents?

The helicopter’s unique ability to fly very low, land and take-off vertically nearly anywhere is also the greatest risk if there are poor human factors. An EC135 accident in November 2015 showed the stark difference between landing and continuing on in poor weather and fading light.

What are the causes of poor culture in the helicopter industry?

Poor culture will often develop with substandard leadership and supervision, and can lead to deviation from software including violations. A culture not conducive to safe flying operations may be imported from other groups that the pilot operates with. The helicopter mustering industry has seen poor culture in the past.

What is the environment of a helicopter?

Environment consists of the internal cockpit with temperature, humidity, noise and vibration as well as the external cockpit with things like weather, sun, moon, terrain and landing areas. Helicopters operate at lower altitudes and not all cockpits are airconditioned, so heat may be an issue.

What are human factors in aviation?

Human factors is a broad term that can mean anything from aeromedicine to how people inside and even outside of the cockpit interact. ICAO uses the SHEL (software, hardware, environment and liveware) model to represent the various components of the human factors’ pantheon.
