What practice, under visual flight rules, can lead to spatial disorientation or collision if the pilot continually flies into instrument conditions?

• A. Continual flight into instrument conditions
• B. Flying at night with no instruments
• C. Flying near clouds
• D. Ignoring checklists

Answer: (A)

Relying on visual cues under visual flight rules means you must keep outside references in view. If you continually fly into instrument conditions, you lose those outside references and have to rely on your flight instruments. The vestibular system and inner-ear cues can’t accurately tell you your true orientation when the horizon isn’t visible, so you can experience spatial disorientation even though you think you’re level or straight-and-level. That disorientation, combined with reduced visual information, makes it easy to misjudge bank or pitch and run into another aircraft or the ground. The important point is to avoid IMC when flying VFR, or transition to instruments if you expect to be in instrument conditions for any length of time. Other scenarios—night flying with no instruments, flying near clouds, or ignoring checklists—pose their own risks, but they don’t describe the same direct hazard of losing orientation from continuing into instrument conditions.
