Questions and answers

What should pilots do in addition to visually clearing for other aircraft?

Clear over the radio in addition to clearing visually.

What type of light should be used inside an aircraft at night?

White light disrupts your night vision, even if used momentarily. Use a red light at night.

Can instructors make mistakes during flight instruction?

Instructors make mistakes too. Many midair collisions have occurred during periods of instruction or supervision.

What does it mean when another aircraft grows larger without relative motion?

If another aircraft appears to have no relative motion in your windscreen but is increasing in size, it is on a direct collision course with you.

When are clearing procedures required?

Execute appropriate clearing procedures before and during all climbs, descents, turns, abnormal maneuvers, or aerobatics.
