FAA Sport Pilot Airplane (SPA)Human Factors and ADMHard
A pilot has flown the same local traffic pattern hundreds of times and has stopped performing a thorough pre-takeoff checklist, instead relying on memory and habit. One day this leads to an unnoticed fuel selector left on an empty tank. This scenario best illustrates which hazard?
- AHyperventilation
- BThe leans
- CSomatogravic illusion
- DComplacency
Show answer & explanationAnswer & explanation
Correct answer: D. Complacency
Complacency is a state of reduced vigilance or self-satisfaction resulting from overfamiliarity with a task, causing a pilot to overlook important details such as checklist items. It is a significant hazard for experienced pilots on routine flights.
Why the other options are wrong
- A. Hyperventilation is a physiological breathing response unrelated to habitual skipping of tasks.
- B. The leans is a vestibular illusion during turning flight, not a checklist behavior issue.
- C. Somatogravic illusion involves misperceived pitch from acceleration, unrelated to this scenario.
Complacency
A state of overconfidence or reduced vigilance resulting from repeated exposure to a task, leading to overlooked hazards or skipped safety steps.
- Common in experienced pilots doing routine, familiar flights
- Leads to skipped checklists or reduced situational awareness
- Countered by treating every flight with fresh discipline and full checklist use
Memory trick: 'Complacency' = comfortable couch potato skipping the checklist
