Flight simulator Flight simulation qer

A flight simulator is a device th at artificially re-creates aircraft flight and various aspects of the flight environment. [ citation needed ] This includes the equations that govern how aircraft fly,how they react to applications of their controls and other aircraft systems, and how theyreact to external environmental factors such as air density, turbul ence, cloud, precipitation,etc. Flight simulation is used for a variety of reasons, including flight training (mainly of pilots), the design and development of the aircraft its elf, and research into aircraftcharacteristics and control handling qualities. [ citation needed ] Depending on their purpose, flight simulations employ various types of hardware, modelingdetail and realism. They can range from PC laptop-based models of aircraft systems tosimple replica cockpits for familiarisation purposes to more complex cockpit simulations withsome working controls and systems to highly detailed cockpit replications with all controls andaircraft systems and wide-field outside-world visual systems, all mounted on six degrees-of-freedom (DOF) motion platf orms whic h move in response to pilot control movements andexternal aerodynamic factors.

The simulator sits on top of either an electronic motion base or a hydraulic lift systemthat reacts to user input and events within the simulation.

As the pilot steers the aircraft, the module he sits in twists and tilts, giving theuser haptic feedback .The word "haptic" refers to the sense of touch, so a haptic system is one that givesthe user feedback he can feel.Ajoystick with force-feedback is an example of a haptic device.Some flight simula tors inclu de a completely enclosed module, while others just have aseries of computer monitors arranged to cover the pilot's field of view.Ideally, the flight simulator will be designed so that when the pilot looks around, hesees the same controls and layout as he would in a real aircraft.Because one aircraft can have a very different cockpit layout than another, there isn'ta perfect simulator choice that can accurately represent every vehicle.Some training centers invest in multiple simulators, while others sacrifice accuracy forconvenience and cost by sticking to one simulator model.

Flight simulators are used as a training device because oftheir overall effectiveness and efficiency in training pilots.

Some of the advantages of using flight simulators includethe following:2

Permit novice pilots to experience simulated flight withoutrisk to him or her or to valuable aircraft.

Availability - that is, flight simulation is not dependent onparticular environmental conditions (good weather), oravailability of a real aircraft. Correspondingly, it is possibleto generate particular conditions without them having tobe sought out in the real world.

Advantages


7/13

Risk-free introduction of emergencies and systems failures.

When used during air crash investigations - ability to accuratelyreplicate the environmental and flight conditions at the time ofan accident to test pilot responses to those conditions.Instructional features recorded flight data, ability to replayand review a simulated flight or parts of it, allow matching ofperformance against criteria.Relieves instructor from flight duties and safety considerations.Permits trainee to make and learn from mistakes without risk.

Advantages


8/13

Accessibility simulation does not require a full flight

progression (pre-flight, take-off, flight, landing, post-flight), but permits repeated practice of a particular stageof flight, such as an ILS approach.Cost-effectiveness savings in crew time, fuel,maintenance to real aircraft, revenue that would be lostusing a real aircraft, and environmental impact.Risk-free introduction of flight challenges, such asconflicting traffic, systems problems, difficult or unusualflight manoeuvres, poor weather conditions, wind sheer,and wake turbulence.

Advantages


9/13

Some of the disadvantages include the following:

Effect of the simulator environment on the operator. In a simulatedaccident situation, for example, we would not expect the simulatoroperator to experience the same stress levels as would be expected inanticipation of a real accident.Simulator users, particularly where used as part of a currency test, maybe expected to have studied and therefore anticipate certain

procedures, conditions, or emergencies during the course of theirsimulated flight.Shorter flight cycles do not accurately reflect pilot fatigue or boredom.In addition to the cost to build a simulator, they have ongoing operationand maintenance costs.

Disadvantages

Problems and solutions

Problems

1. The software is only as goodas the engineers designing itand the situations its designedfor

2. Simulator training is creditedwith saving thousands of lives.But the problem, is that in rarebut critical instances they cantrick pilots into habits that leadto catastrophic mistakes.

Solutions

The engineers that design themachine or program shouldconduct test in order to acquirereal life data and apply it to thesoftware in terms of how to

control the plane.The pilot can perform simulationbut he must also perform real-lifetraining in order to acquire a realexperience of the situation


11/13


Problems

1. The simulation does notrepresent ALL possibilities ofaccidents that might occur

2. The parts or devices in thesimulator machine might bedamaged or spoiled. Thus,the simulator cannot run themachine.

Solutions

They designer must gatherinformation from authorities such asengineers to study the worst-casescenario and apply it in thesimulationThe designer must equip themachine with the best material sothat it would not be damaged as it isused over and over again.A team of mechanics should beformed in terms of maintanance


12/13


Problems

1. The program or software arebased on a computer. So it isexposed to risks such asvirus.

2. The software can becomeobsolete and certainsimulator does not providetraining for all planes

Solutions

Proper firewall or antivirusshould be install in it so that itmight encounter the virusa R&D team is compulsory toovercome these problems.They should conduct researchto improve the software.
