FAA Aircraft Dispatcher (ADX)Regulations (Part 121)Medium
According to 14 CFR 121.463, an aircraft dispatcher who has been on duty may not be scheduled for more than how many consecutive hours of duty in a 24-consecutive-hour period without being given a rest period, unless relief is provided by another qualified dispatcher?
- A8 hours
- B10 hours
- C12 hours
- D14 hours
Show answer & explanationAnswer & explanation
Correct answer: B. 10 hours
14 CFR 121.463 limits scheduled dispatcher duty to 10 consecutive hours in a 24-hour period; duty beyond that requires a relief dispatcher. The regulation also requires a minimum rest period before the next duty period begins.
Why the other options are wrong
- A. 8 hours is not the scheduled duty limit under this rule.
- C. 12 hours exceeds the regulatory scheduled duty limit.
- D. 14 hours far exceeds the allowed scheduled duty period.
