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, maximum performance takeoffs at Vx or Vy can be risky due to a narrow stall margin in the event of an engine failure.
- It's generally safer to climb at a cruise climb speed (Vcc) as it offers better visibility, passenger comfort, and crucial extra airspeed to react to an engine emergency, reducing the risk of a stall.
- If Vcc is not listed in the POH, it can be approximated using the rule of thumb: `Vy + (Vy - Vx)`, providing a beneficial safety margin above stall speed.
