Human performance

Medical and current operational capability are separate aspects. Acute impairments can exclude a flight despite a valid document.

Technical coverage is limited. Looking outside and the other procedures remain necessary.

Sensory impressions can deviate from the actual position in the air. Appropriate visibility conditions and trained procedures are crucial.

CO is not smelled reliably and can dangerously affect performance. Appropriate precautions and proper procedures are important.

Preparation and clear priorities reduce avoidable burdens. Safe flight guidance remains the central task.

The confirmation error filters information in favor of an existing assumption. Conscious testing of counter-arguments helps against this.
