(Related to, but hopefully not a dupe of, this question)
The latest NASA ASRS newsletter includes the case of an A320 crew that forgot to retract the gear and started detailed troubleshooting without noticing that the gear was still down. The captain said in his report that:
I instructed the First Officer to coordinate landing at the divert airport while I briefed the Lead Flight Attendant and then performed the Airframe Vibration Checklist
The mention of an airframe vibration checklist caught my attention because it's such a specific scenario. So, excluding normal operations, how many checklists does a typical airliner (like the A320) have for unusual/abnormal/emergency scenarios?
