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. By disabling it and replacing it with our own, they show as disabled. The MEL (Minimum Equipment List) allows aircraft to depart with certain systems partially or completely INOP (inoperative). Airbus A320 Flight Control Surfaces Working Principle. Aviation Nuggets. NOTE: Record the ELAC 1 reset in the logbook (successful or unsuccessful). We also take a quic Contact Information. : A320-27-1243 The main calculators for Airbus A320 family are: ELAC: elevator and aileron computer; SEC: spoiler and elevator computer; FAC: flight augmentation computer; SFCC: secondary flight control computer; They are redundant and some functions dedicated to one computer can also be executed on other computers. Updated on February 1, 2024. The other day we had an ELAC2 failure in flight that was easily resolved by s/w off option (reset didn't work), however felt uneasy working on In normal operation the Ailerons are controlled by ELAC 1 using one servocontrol per aileron. This is two completely independent chains including different actual control surfaces except for the side-sticks. A similar TR reference 568-1 was issued for the QRH 2. A. Elevator and Aileron Computer (Airbus A320) ELAC: Extraneous Logical and in Expression Used as Branch Condition (software fault) ELAC: A share cockpit config for Microsoft Flight Simulator's Fenixsim A320, based on Yourcontrols. GND SPLR 1 + 2 (3 + 4) - A320 aircraft fitted with sharklets: inhibition of anti-pitch up law used at high Mach and high AOA when speedbrakes are extended. Scenario - ELAC 1 U/S at dispatch (permitted acc. Last Ditch. ELAC is defined as Elevator and Aileron Computer (Airbus A320) frequently. JAOC2C 24-01. You will immediately feel, hear, and see the differences between the A319, A320, and A321 respectively, and learn to master their unique traits. General.
