When taking off from your home airport, what’s your preferred departure technique? Do you choose to climb at Vx (best angle-of-climb airspeed), Vy (best rate-of-climb airspeed) or perhaps some other speed?
Calculating Cruise Climb Speed
Key Takeaways:
- For high-performance piston singles, using Vx or Vy for departure may not be the safest due to a significantly narrower margin above stall speed in the event of an engine failure.
- A cruise climb (Vcc) is generally recommended instead, providing better visibility, passenger comfort, and crucial extra airspeed for reaction time during an engine emergency immediately after takeoff.
- If Vcc is not listed in the aircraft's POH, it can be approximated using the rule of thumb: Vcc = Vy + (Vy - Vx), which helps ensure a safer airspeed margin.
