What problem was shown with controlled rest on the flight deck?

• A. Increased monitoring improved safety
• B. Shorter rest periods do not affect safety
• C. The crew experienced no issues with controlled rest
• D. Reduced monitoring led to loss of awareness and a runway incident

Answer: (D)

Controlled rest relies on one pilot staying awake to monitor the flight while the other rests. The key risk is that the awake pilot bears the full load and must maintain constant vigilance; if fatigue, distraction, or miscommunication reduces that monitoring, critical cues can be missed. In the scenario described, this reduced monitoring led to a loss of awareness and a runway incident. This illustrates why controlled rest must be tightly managed with clear wake-up procedures, cross-checks, and crew coordination, especially during critical phases like takeoff and landing.
