Action description

Alliance Airlines has made the following amendments to its Operations Policy and Procedures Manual:

  • in E190 aircraft with Load 25 software, the multifunction control and display unit (MCDU) page displaying the planned landing flap should be selected on the pilot flying side before the approach commences
  • when completing the before landing checklist, the flap set check now requires that the landing flap setting in the engine-indicating and crew alerting system is crosschecked with the flap setting in the MCDU.
