What is the maximum VTOL take-off and landing slope angle?

The maximum VTOL (Vertical Take-Off and Landing) take-off and landing slope angle is 9°. This value is critical for operations because it defines the safe limits within which a VTOL aircraft can perform both take-offs and landings without risking performance degradation or safety issues.

Exceeding this slope angle during these critical phases of flight can lead to increased power demands on the engines, potential loss of control, inadequate lift, or complications in descent and ascent profiles. Thus, adhering to the 9° guideline ensures that pilots can maintain optimal performance and safety margins in varied operational environments. This regulation reflects the engineering and design capabilities of most modern VTOL aircraft, ensuring that they remain within operational limits for effective handling during these challenging flight phases.
