What does "perception-based performance breakdown" mean?

• _s 6y ago
  Most light sport aircraft are day VFR only, with an altimeter and airspeed indicator being the primary instruments. Some ultra lights don’t even have those, and you use visual cues and the “feel” of the craft to judge your energy/speed/height - and our perceptions are not the most reliable.

  Fancy words for "pilot fucked up."

  Refers to a problem where the pilot did the wrong thing because of disorientation or perceptual confusion. Take controlled flight into terrain, a common enough problem that aviation safety writing just calls it CFIT. This is when an aircraft collides with terrain, but there was no loss of control. CFIT is a relatively common occurrence, but why does someone fly a completely controllable aircraft into the ground? Almost always due to perceptual confusion, disorientation either to attitude or location. Unintended entry into instrument conditions (e.g. into a cloud or fog bank) is one cause, but disorientation can occur for a number of other reasons as well, including in good weather conditions.
