EASA ATPL Performance | Revision | Chapter 7 - V speeds 2023/2024

EASA ATPL Performance | Revision | Chapter 7 - V speedsApproach Climb Speed - correct answers - Recommended speed for initial climb out following a missed approach, initiated at or above the decision height. Conditions: - Critical power unit INOP - MLM - Gear Up Class A: - Twin: 2.1% - Three: 2.4% - Four: 2.7% Not faster than 1.5Vs Buffet Speed - correct answers The speed at which aerodynamic flow becomes turbulent and causes uncontrollable vibration of the airframe Cruising Speed - correct answers Representative TAS, to the nearest 10kt, used for aeroplanes of the type to calculate their compliance regarding over-water flight and two-engine-INOP data Flaps-Up Safety Speed - correct answers 1.2Vs, safety speed during the 4th segment of the six-segment net flight path Landing Approach Speed - correct answers - CAS in the landing configuration which must be maintained down to a screen height of 50' during a stabilised approach. - Not less than 1.3Vs Landing Climb Speed - correct answers - Recommended speed for the intial climb-out after a baulked landing. Conditions: - All power units operating - Landing configuration - At the power obtained 8s after initiation Allows, in the above configuration, a gradient of climb of 3.2% - Never less than Vmcl - Not greater than 1.3Vs - 1.15Vs for 4 engines - 1.2Vs for other Class A Maximum Abandonment Speed - correct answers The highest speed from which a takeoff with all engines operating on a contaminated surface can be abandoned with a reasonable degree of safety. Normal OEI Cruise - correct answers The TAS in ISA computed from the AUW at 2 hours after takeoff at MTOM and climbing to, and maintaining, the all engines operating optimum initial cruise level for long range cruise. V1 - correct answers - Never less than Vef + speed increase after engine failure to the point at which the pilot first applies the means of retardation. - Not greater than Vr or Vmbe - 2s delay built in V2 - correct answers - Speed must be attained upon reaching screen height with OEI - Varies with air density, TOM, and flap setting - Not less than V2min - Not less than Vr + the increment attained before reaching screen height with all operative power units at MTOP V2min - correct answers - Minimum that V2 may be in terms of CAS
