Flashcards; Learn; Test; Match; ELAC 2. Its been 20 years since I did the school but the priority I think for elevators was that elac 2 was the last resort. Basically, what this schematic is saying is that the ELAC's, under normal law, provide turn coordination and dutch roll damping to the FAC's. Today, we're diving into one of the main computers of the Flight Control system: the ELACs. There are faults indicated for electrical systems, hydraulics, engines, flight controls, anti-ice systems, fuel systems, navigation equipment, bleed air, landing gear, brakes, and other A320 in service experience 8: "A320 and B757 on the liner: line pilot's perspective", by S.

This is two completely independent chains including different actual control surfaces except for the side-sticks. ELAC 1 and 2 perform the following: Normal pitch and roll, normal LAF (Load Alleviation Function). ELAC pushbutton controls the Elevator and Aileron Computer (ELAC) 1(2). Later revisions of the above document approved by the DGAC are acceptable for compliance with this Directive. Photo: Clemens Vasters ELAC (Elevator Aileron Computer) Normally, ELAC 1 commands the operation of the ailerons and ELAC 2 commands the operation of the elevators and horizontal stabilizer. It processes pilot inputs and sends signals to move Each aileron can be powered by two servocontrols signalled by two Elevator and Aileron Computers (ELAC) and supplied from different hydraulic systems. Abbreviation to define. 28th Apr 2010, 06:03. ( 11 ) will provide mode feed back to the ELAC and SEC's. txt) or read online for free. The uncontrolled roll, due to the malfunction of the pilot flying's sidestick, was recovered by the other pilot and the aircraft safely returned to land in Frankfurt without further incident. Thus, four different entities coexist: control channel A320 EFCS & ELAC by nur8alifa8biswardi If ELAC 1 or Blue Hyd fails, control passes to ELAC 2 using only the Green Hyd jack. Tech Log - A320 Beta Target - Hi Question regarding ELACs and Beta Target on A320/321.

Is it standard practice to just cycle the relevant switches which then clears the fault, or is this a QRH actionable event? Does this happen primarily when the flight deck is The ELAC will keep the turn level by adjusting the elevators to maintain your flight path and the FAC will balance the turn with rudder. Introduction The first electrical flight control system for a civil aircraft was designed by Aerospatiale and installed on Concorde. If ELAC 2 fails, OR Green hydraulics fail; control will be passed to ELAC 1 which will control the surface using Blue hydraulics. f/ctl elac 2 pitch fault; f/ctl elev servo fault; f/ctl fcdc 1 fault; f/ctl fcdc 1+2 fault; Airbus A320 no go - Free download as Word Doc (.

For anyone in the future, I applied a band aid solution by going to the screen on the left, clicking on the truck icon in the sidebar, clicking Fuel in the top right, going to the slider at the bottom, dragging it to full and pressing the "play" button. The ELAC and FAC are composed of two identical units each, the SEC of three identical units (but only two of the units are used as backup for ELAC). The roll and pitch controls of the aircraft are electrical. From the A320 FCOM DSC-27-20-10-20. Pier Seven Aviation's A320 Full Flight Simulator is certified to EASA and qualified to Level D.

The purpose of this Technology Demonstration Project (TDP) is to determine if the IFDIS can detect the intermittent faults present in ELACs that none of the test equipment currently available to ELAC stands for Elevator and Aileron Computer (Airbus A320). Location: Middle East. But I fell in love with the Airbus A320 as it is the first civil fly-by-wire plane. However, it is not allowed to dispatch an Airbus A320 with an inoperative ELAC 2. The left elevator is normally controlled by ELAC 2 using the Green Hyd jack. As a result, Airbus A318/A319/A320/A321 QRH System Reset table has been updated from 06. 61 terms. Thus, the A320 has two types of computers (ELAC, SEC), each computer has a control channel and a monitoring one.

The FAULT light goes off, when flight crew selects OFF, or at the end of the ELAC power-up test, if its results are acceptable. Have you ever experienced this ECAM warning [ ELAC 1(2) PITCH FAULT ] after manually restricting the movement of the trim wheel as the aircraft is automatically re-trimming to 0 after landing/during touch-&-go? SLT. Bespoke flight and engine models per variant. Note: The ELAC power-up test occurs when electrical power is turned on, or after the occurrence of an electrical transient lasting longer than 25 ms. A/C dispatched same thing happed again next flight. I am using Airbus X Extended A320/A321, and the issue to my flotation issues on landing is this It seems that the plane is almost flying itself, so I wanted to disable all manual flight control by disabling the ELAC, FLT CTRL, and SEC's switches, but they don't disable when I right or left click on them; they seem to be in-operable.
