Issue When altering the Vapp entry or adjusting altitude constraints, the Flight Plan (F-PLN) profile undergoes a re-computation. If the Required Time of Arrival (RTA) function had been utilized prior to these modifications, the MCDU and PFD may unexpectedly present inaccurate speed targets. In addition, this scenario could occur if the flight crew has initially…

Issue On the Airbus A320, the “CHECK WEIGHT” message appears on MCDU when there’s a significant disagreement between the gross weight computed by FMGC and the gross weight computed by FAC. This could indicate a potential discrepancy in the aircraft’s weight calculations, which is crucial for safe flight operations. The threshold for triggering this message is…

Issue: As the wording suggests, the condition arises when ‘G/S’ is displayed as armed on the FMA despite not being expected. This issue occurs when the following conditions are satisfied within a timeframe of less than 1.5 seconds: AP 1+2 set to OFF FD 1+2 set to OFF A/THR set to OFF. Here, although AP/FDs…

Issue: This problem typically occurs when the aircraft encounters certain conditions, such as an unusual position of the LOC ground antenna or when the LOC course isn’t properly aligned with the runway axis. In these situations, the aircraft may oscillate on one side of the LOC axis, potentially leading to unstable flight or difficulty in…
