Aviation is full of jargon and technical terms. Other times, everyday words are used in new and unexpected ways. It is used throughout the industry but is especially noteworthy in Airbus aircraft.

Numerous jokes have popped up. After all, who would want to fly a plane that insults its pilot? For example, chemicals are used to retard the spread of fire. In the example of an aircraft, the thrust levers are moved aft to retard the power produced by the engines. The Airbus computers are reminding the pilot to move the thrust levers to their idle detent. Why does the pilot need to be reminded?

The word is not only associated jet planes crashing function Airbus aircrafthowever. The verb is used throughout industry publications and training to describe the action of reducing power.

Often, mechanical throttles found in small aircraft use jet planes crashing function terminology open and close, to describe the actions of controlling the butterfly valve inside the carburetor. When the throttle is advanced, or opened, the butterfly valve allows the maximum amount of fuel and air into the cylinders. When the throttle is closed, or retarded, the amount of fuel jet planes crashing function air is reduced, and power decreases.

The use of open and closed is related only to reciprocating engines, however. On jet-powered aircraft, thrust lever position is usually advanced or reduced. By the time a pilot get to the flight deck of an airliner, he or she has many hours under their belt. When told to retard jet planes crashing function, their hands will fly to the power levers, because that word has been associated in their minds to the throttle position.

Autothrottle technology has been around in jetliners and corporate airplanes since the s. By setting the throttles or power levers to max takeoff, the system will deliver the maximum thrust without the pilots fussing over power settings.

Likewise, the system will optimize power jet planes crashing function for every phase of flight, like climb and cruise. As the pilot commands a pitch up to climb or banks into a turn, the autothrottle system automatically commands more power to the engines. The final airspeed should remain constant. When approaching a runway in gusty conditions, an autothrottle system makes many small power corrections and maintains airspeeds far more consistently than a human pilot can.

One of the greatest benefits of the technology is that it adds a fourth dimension to autopilot systems. Most small aircraft only have roll and pitch control. Larger planes include yaw control. A plane with autothrottles can easily incorporate power or speed control. On most equipped airplanes, the desired airspeed is selected into the autopilot, just like altitude or heading is.

Autothrottles come in two variants, front-driven or back-driven. Back-driven systems set power based on thrust lever positioning. The levers move via servos when the system makes power settings. The levers do not move as the system adds or reduces power. Read more about the history and advantages of autothrottle technology from Flying Magazine.

Pilots must learn to use and to listen to all available resources. Over the decades, jet planes crashing function procedures and techniques that pilots use to work together in cramped flight decks have been polished and perfected. While every operator may do things a little differently, crew resource management CRM is the set of skills that all pilots must develop to share responsibility in the cockpit.

There are many sides to the CRM equation, but briefings and callouts are some of the most visible. Jet planes crashing function all times on the flight deck, there is a designated pilot flying PFwhile the other pilot is the pilot monitoring PMor sometimes called the pilot not flying PNF.

Ideally, the PF is doing jet planes crashing function of the actual hands-on flying or controlling and monitoring of the autopilot. In doing so, the PM shall brief the PF on what jet planes crashing function been done and what is coming up. Briefings provide a standardized way for the PM to describe the procedures. As succinctly as possible, the PM tells the PF what to look at and when. In the example of an instrument approach procedure, the PM will review the approach plates with the PF and describe how the aircraft is going to fly the approach.

Callouts serve a similar function in that they keep everyone on the flight deck focused on the essential items during critical phases of flight.

On takeoff, the pilot monitoring should be carefully monitoring the airspeed and should call out V1, V2, and rotation speeds. These speeds are previously calculated and agreed upon before commencing the takeoff roll, but the pilot flying might be distracted and focused on another task, like fighting a crosswind. Having the PM make these callouts ensures that each jet planes crashing function on board knows exactly what the plan is at each point.

These critical airspeeds benchmark the flight profile, and the plan of action should anything go wrong. By having two pilots on board, they can divide their attention and accomplish more as a whole than either one can do individually. Automation has taken over some callouts for us.

Aural, or sound, alerts are used in some advanced avionics systems to grab the attention of those on the flight deck. Ground proximity warning systems GPWSfor example, use radar altimeter to measure height above ground.

Most large aircraft use their radar altimeters to trigger callouts for low altitude. This is an explanatory description of crew resource management to illustrate the importance of callouts and briefings. Actual CRM skills vary slightly from company to company and is an integral part of pilot training at the airline or air charter operator level.

The importance of the RETARD aural alert in Airbus aircraft is an important case study in why knowing the systems of the aircraft is vital knowledge for pilots. The Jet planes crashing function A was the first completely fly-by-wire airliner. Fly-by-wire technology uses only electronic signals and computer programming to move flight controls and to change jet planes crashing function settings.

The position of the flight controls and the inputs pilots make Jet Planes Crashing Rules with them first gets analyzed by the flight computer systems before a resultant force is placed on the control surfaces. This jet planes crashing function integrates the use of front-driven autothrottles.

Unlike aircraft that use back-driven jet planes crashing function, the Airbus thrust levers do not change position on their own. The levers have certain detents built-in. The computer is often changing the power setting during the flight to maintain airspeed. But the throttle position also provides a signal to the automated flight systems to cue other features, like auto braking and air spoilersthe movement of the throttle is critical for a safe landing.

Any additional power at this critical time would cause the aircraft to float on the runway and prolong the jet planes crashing function roll. In these planes, you can then watch the thrust levers move aft, since they are equipped with back-driven autothrottles.
