What climb speed should I use for a private pilot checkride?
Use the right Vx or Vy on an FAA private pilot checkride, including ACS tolerances, POH differences and fixes for common climb-speed errors.
For an FAA private pilot checkride, use the speed published for the exact aircraft and manoeuvre: the recommended normal-climb speed or Vy after a normal take-off, and Vx or the recommended obstacle-clearance speed for a short-field departure before transitioning to Vy. The POH/AFM—not a memorised generic number—controls.
This is an Aviation & Real-World Flying procedure, not a simulator convention. The examiner is assessing whether you select, explain and maintain the correct aircraft-specific speed rather than recall a fleet-wide Cessna or Piper figure.
Which climb speed applies to each checkride take-off?
The required climb speed changes with the take-off task.
| Checkride task | Speed to use | Key point |
|---|---|---|
| Normal take-off and climb | Manufacturer-recommended normal-climb speed or Vy | A published cruise-climb range may be the normal recommendation; Vy is not automatically required if the POH specifies something else. |
| Short-field take-off with an obstacle | Recommended obstacle-clearance speed or Vx until clear, then the recommended climb speed or Vy | Vx gives the greatest altitude gain per horizontal distance; Vy gives the greatest altitude gain per unit of time. |
| Soft-field take-off | Accelerate in ground effect to Vx or Vy as appropriate, then use the published climb procedure | The exact sequence, flap setting and speed are aircraft-specific. |
| Go-around | Manufacturer-recommended climb speed or Vy while changing configuration as prescribed | Apply power, control pitch and retract flap or landing gear in the POH sequence rather than rushing the configuration changes. |
Our explanation of how to choose between Vx, Vy and cruise climb covers the operational differences in more detail. If you fly a 172, check the model-specific Cessna 172 V-speeds and their meanings; numbers from another 172 variant may be wrong for your aircraft.
How accurately must I hold climb speed?
For common FAA private-pilot take-off and go-around tasks, the Airman Certification Standards generally call for the nominated climb speed within +10/-5 knots.
That is an evaluation tolerance, not a target range. Aim for the published speed itself rather than planning to fly five knots slow. If the POH provides a normal-climb range, choose a deliberate target within that range and hold it steadily; do not add the entire ACS tolerance to both ends of the published range.
The examiner also considers directional control, coordination, configuration, obstacle clearance and division of attention. Holding the number while drifting from the centreline or staring continuously at the airspeed indicator is not satisfactory aircraft control. For the wider test context, see our guide to ACS tasks and aircraft-control expectations during the FAA checkride.
If your licensing authority calls the test a skill test rather than a checkride, its numerical tolerances may differ. The aircraft's approved operating data still determines the speed.
How do I find the correct speed for my aircraft?
The correct number comes from the approved POH or AFM and any applicable supplement for the aircraft being flown.
- Identify the exact aircraft. Confirm the model, variant and any modification that changes take-off performance or approved speeds. A supplement can override information in the original manual.
- Read each take-off procedure. Check normal, short-field, soft-field and go-around sections separately. Do not assume one climb speed applies to every task.
- Check the conditions. Use any published adjustments for altitude, weight and configuration. Some aircraft provide a speed schedule; others publish one value or a range.
- Confirm the units. Older manuals and airspeed indicators may use miles per hour rather than knots. Confusing MPH with KIAS creates a substantial error.
- Prepare a compact reference. Record rotation speed, Vx, Vy, the normal-climb recommendation and any altitude schedule. A school checklist is useful only when it agrees with the approved aircraft data.
Does density altitude change the target climb speed?
Do not add knots to an indicated climb-speed target merely because density altitude is high.
Higher density altitude increases true airspeed for a given indicated airspeed and reduces climb performance, but the pilot normally flies the POH's stated indicated airspeed. If the manual publishes altitude corrections, use them: indicated Vx often rises with altitude while indicated Vy falls, but the exact schedule belongs to that aircraft.
Weight can also affect the optimum speed. Apply a weight correction only when the approved data provides one; do not invent a rule-of-thumb adjustment during the checkride.
What climb-speed mistakes cause checkride problems?
Most climb-speed errors come from using the wrong reference or allowing speed control to consume all the pilot's attention.
- Using a number from another model: verify the actual POH rather than relying on a generic training flashcard.
- Confusing rotation speed with climb speed: rotation establishes the lift-off attitude; after lift-off, adjust pitch to capture the required climb speed.
- Holding Vx after the obstacle: transition to the recommended climb speed or Vy once the obstacle is cleared unless the procedure says otherwise.
- Chasing the airspeed indicator: set a known pitch attitude, cross-check the speed, make small corrections and trim. Large pitch changes usually produce oscillation.
- Ignoring configuration: flap and landing-gear changes alter drag and pitch. Use the published sequence while maintaining a positive climb.
- Adding speed because conditions are poor: an arbitrary increase can reduce obstacle-clearance angle. Recalculate performance and reject the take-off if the margins are inadequate.
What should I brief before the take-off?
Brief the target speed, its source, the configuration and the point where you will transition from Vx to Vy.
For a short-field demonstration, identify the simulated or actual obstacle reference and what constitutes clearing it. State the planned speed aloud when useful, then fly it without fixating on the instruments. Our overview of the complete light-aircraft departure sequence explains how these speeds fit with rotation, ground effect, configuration and the initial climb.
