Seven Ways Darkness Can Mislead You
Recognize autokinesis, fixation, false horizons, reversible perspective, size-distance errors, flicker effects, and black-hole conditions.
YOU WILL BE ABLE TO
- 01Identify the rule, source, or principle behind this idea: An isolated light may appear to move when stared at without reference.
- 02Explain the operational effect of this idea: Sparse or misleading ground lights can create a false horizon or distort distance and closure.
- 03Apply the lesson to a new mission and defend a go, modify, or no-go decision.
01 / MISSION
Begin with the operating problem.
During a dark approach, a single light seems to drift while the horizon is not visible.
02 / CORE BRIEF
What the remote pilot needs to know.
An isolated light may appear to move when stared at without reference.
Sparse or misleading ground lights can create a false horizon or distort distance and closure.
Fixation narrows attention and delays detection of traffic, battery, and route changes.
03 / PILOT DECISION
Make the call.
Break fixation, cross-check attitude and position with reliable references, use the crew, and discontinue the approach if orientation remains uncertain.
04 / FIELD CHECK
Put it into the flight plan.
Name the likely illusion and its planned countermeasure in every night risk brief.
05 / KNOWLEDGE CHECK
What is the first response to suspected autokinesis?
Reveal the debrief
Stop staring at the isolated light, scan with references, and cross-check aircraft position and attitude.
