Diese Lernkarten behandeln Leistungsberechnungen für Start, Steigflug, Landung und Hindernisumgehung bei verschiedenen Flugzeugklassen (A und B) sowie spezifische Geschwindigkeiten wie V1, VR und V2. Sie erklären Faktoren für Start- und Landestrecken auf unterschiedlichen Pistenbelägen, Netto- und Bruttostandards sowie Driftdown- und Balked-Landing-Anforderungen. Pilot:innen und Flugbetriebsfachkräfte profitieren von diesem Wissen, um sichere und regelkonforme Flugdurchführungen zu gewährleisten.
