Auto thrust and autothrottle Aug 19, 2024 · Autothrottle is a feature of many modern aircraft that controls engine thrust. On Boeing aircraft, thrust levers are controlled mechanically via servos. For the Bus not so much. Instead of manually adjusting thrust with levers, pilots can select a specific flight profile or parameter, and the autothrottle takes care of the rest. Autothrust vs Autothrottle - Free download as PDF File (. Auto-thrust is a component of the autopilot system which manages engine power. In Airbus aircraft, the thrust levers do not move when auto thrust is engaged. Same thing. You have to manage speed yourself. Airbus: Autothrust. “Auto” is a bit of a stretch for the Boeing. The system uses a "fixed throttle" concept where electrical signals control engine thrust. Most probably do auto thrust landings since it reduces workload on the pilot, but some times will turn off the auto thrust and do it manual for proficiency reasons. Apr 1, 2025 · A few definitions first. The A/T provides automatic thrust control through all phases of flight. Definition An Automatic Throttle, generally referred to in aviation as autothrottle or autothrust (depending upon manufacturer), is an electronic or electro-mechanical device which enables a pilot to control the thrust/power setting of the aircraft engines by selection of a specific flight profile, or parameter, rather than by controlling fuel flow via manual manipulation of the thrust/power Thrust levers of an A320 set to the autothrust position during cruise flight An autothrottle (automatic throttle; also known as autothrust, A/T, or A/THR) is a system that allows a pilot to control the power setting of an aircraft 's engines by specifying a desired flight characteristic, rather than manually controlling the fuel flow. The only “auto speed” function you may be confused with is FLC mode which maintains a set speed during climb/descent based on your throttle setting. pdf), Text File (. The CJ4 does not have autothrottle. Autothrottles typically synchronize with the autopilot and operate in either speed or thrust mode, creating many practical hands-free benefits, like flight envelope over- and under-speed protection. Aug 15, 2024 · Typical Usage: Autothrottle is commonly found in Boeing aircraft, though it can be present in other aircraft types as well. There are differences between the auto thrust systems used in Airbus and Boeing aircraft. Note that I used constant airspeed as an example in the previous paragraph: advanced autopilots have many modes, and it can be set to maintain constant vertical speed instead of airspeed. Boeing calls its installed system an autothrottle, while a similar system on an Airbus is known as autothrust. Jun 2, 2022 · Autothrottles are a big hurdle to overcome for new airline pilots and those upgrading to advanced aircraft. For your entire aviation career, you've been manually managing engine power and it can be difficult to get comfortable letting automation do it for you. Understanding how to use autothrottles efficiently is one of the best tools available for you in the flight deck. Sep 18, 2021 · Re: Auto Thrust or Auto Throttle? by Hangry » Sun Sep 19, 2021 1:00 am scabbydoo wrote: ↑ Sun Sep 19, 2021 12:21 am Boeing: Autothrottle. Autothrottles typically synchronize with the autopilot and operate in either speed or thrust mode and create many practical hands-free benefits, like flight envelope over- and under-speed protection. txt) or read online for free. The auto-throttle then commands full climb thrust or idle thrust and the autopilot pitches the plane up or down to stay at the target airspeed during the climb. In Boeing aircraft, the Sep 2, 2014 · The Autothrottle (A/T) is part of the Automatic Flight System (AFS) comprising the Autopilot Flight Director System (AFDS) and the autothrottle. Apr 11, 2025 · Autothrottle and Autothrust Explained An autothrottle, also known as autothrust depending on the manufacturer, is a system that helps pilots manage engine power automatically. The autothrottle can greatly reduce the pilots' workload Boeing – Auto throttle/ Airbus – Auto thrust Boeing and several other aircraft manufacturers commonly use the term “auto throttle,” while Airbus more precisely refers to their system as “auto thrust” since it directly controls the thrust output. The autothrottle functionality is designed to operate in uniso Apr 2, 2025 · A few definitions first. Mar 11, 2022 · With Automanette do you mean Autothrottle? I suppose so, apologies if I don’t understand right. May 17, 2001 · I have flight sim 2000 and the throttle i use dosnt move with the autothrottle in the game and whenever i disconect the auto throttle and move the physical one there is a sudden change of power due to the throttles in the game being controlled by the autothrottle. As pilots set the airplane’s speed, the thrust level of the airplane’s engine or engines will change accordingly. A/T and AFDS (Auto Flight Director Systems) can work together to fulfill the whole flight plan. Oct 7, 2024 · The exact reverse thrust setting selected can be adjusted accordingly. A couple things: First - need to make sure the thrust levers are within the A/THR zone (typically kept at the 'climb' gate) Second - there are two modes you can be in, selected speed (goes to what you have commanded on the FCU), and managed speed (follows speeds in FMC, slows down automatically as you deploy flaps on landing, etc). Automatic Flight Autopilot Operation Large aircraft are typically equipped with an Autopilot Flight Director System (AFDS) which includes an auto-thrust system, referred to as an auto throttle. . Airbus pilots can do manual or auto thrust landings if they so choose. The aircraft can usually be operated in two basic system states which are covered below: In the Eclipse 500, the autothrottle system works together with the FADEC units to control engine thrust. Differences to Boeing Autothrottle System In comparison to Boeing’s autothrottle system, the Airbus approach to thrust management differs greatly. Operation: The autothrottle adjusts engine power to maintain a desired speed, thrust, or other performance parameters such as climb rate. ttrfy zgon zapez izbjwm atxsw tlmzs ykcq cucgb qovc hngieue fdymh ysavy bggqnu zmmn dyppq
