What does the TOGA button do?

TOGA is a flight mode which stands for Take off/ Go around. It is not just a power setting, it is a mode which changes the power of the engine (if the aircraft is equipped with an auto throttle/thrust) and also the flight path. Most airplanes have the TOGA button located on the side of the thrust levers.

Which type of engine is used in aircraft?

Jet engines move the airplane forward with a great force that is produced by a tremendous thrust and causes the plane to fly very fast. All jet engines, which are also called gas turbines, work on the same principle. The engine sucks air in at the front with a fan.

Are piston engines still used in aircraft?

Nowadays, piston engines are generally used only on very small general-aviation airplanes… and are no less reliable than the turboprops and jets on larger aircraft.

How do you choose an aircraft engine?

Pay attention to mounting and compatibility issues. Look Into Power – Even smaller engines like the PT6A can deliver big levels of thrust and horsepower. Engines that are too small may not have the thrust to lift a plane off the ground, while engines that are too large could damage the plane itself.

What can happen when the engines are running on TOGA thrust for too long *?

The Pilot Flying (PF) moved both thrust levers forward and paused for around 3 seconds near to the CLB detent where, the EPR and N2 increased to the the following values: ENG 1: 1.03 EPR 78\% N2. ENG 2: 1.24 EPR 91\% N2.

What can happen when the engines are running on TOGA thrust for too long?

The strong longitudinal acceleration induced by the TOGA thrust may ultimately lead to Spatial Disorientation (SD) of the flight crew caused by a Somatogravic Illusion (SI). SI is a suspected element in several fatal accidents.

What is the difference between engine and powerplant?

Like a motorcar engine, a gas engine power plant is characterized by a four-stroke cycle. The major difference is that the fuel is natural gas or others. The engine connects to a generator for electricity generation. Similar to a car engine, this engine warms up and produces waste heat.

How does a plane generate thrust?

Thrust is generated by the engines of the aircraft through some kind of propulsion system. Thrust is a mechanical force, so the propulsion system must be in physical contact with a working fluid to produce thrust. Thrust is generated most often through the reaction of accelerating a mass of gas.

How do jet engines deal with rain?

During freezing rain while sitting on the ground waiting for takeoff, pilots are also trained to rev the engines frequently to prevent ice accumulation. Another design feature that helps keep a jet engine operating in heavy precipitation is igniters, similar to spark plugs, in the combustion section.

How does the pilot control thrust in an airplane?

The pilot controls thrust by adjustment of the control levers for the engine. In an aircraft with a reciprocating engine these can consist of a throttle, mixture control (to control the ratio of fuel and air going to the engine), and propeller control as well as secondary devices such as supercharger controls or water-alcohol injection.

How does the thrust lever work in a jet engine?

The thrust lever is linked to a fuel control and/or electronic engine computer that meters fuel flow based upon revolutions per minute (rpm), internal temperatures, ambient conditions, and other factors. [Figure 15-3] In a jet engine, each major rotating section usually has a separate gauge devoted to monitoring its speed of rotation.

What is the principal control of turbojet engine?

In a turbojet engine, the principal control is the throttle, with auxiliary devices such as water injection and afterburners. With water injection, a water-alcohol mixture is injected into the combustion area to cool it, which allows more fuel to be burned.

How do aircraft propellers work?

Most modern aircraft have an automatic variable-pitch propeller, which can be set to operate continuously in the most efficient mode for the flight regime. If an engine fails, most modern propellers can be feathered (mechanically adjusted) so that they present the blade edgewise to the line of flight, thereby reducing drag.
