When should cockpit lights be adjusted to minimize glare during night operations?

Cockpit lights should be adjusted to minimize glare during night operations before takeoff. This timing is crucial because setting the lights properly beforehand helps ensure that the pilots' visual adaptation to the darker outside environment is optimized right from the beginning of the flight.

Ensuring that cockpit illumination is appropriate before takeoff allows pilots to reduce the strain on their eyes while still being able to read instruments clearly. It also helps to prevent any sudden changes in lighting conditions that can lead to temporary blindness or difficulty adjusting to outside visibility during critical phases like takeoff.

Adjusting the lights before takeoff provides a safer and more effective way to enhance situational awareness, allowing pilots to focus on their primary responsibilities without the distraction of glare or inadequate lighting.
