Cessna 172S V Speeds Overview

Cessna 172S V Speeds

• VNE: Never Exceed Speed at 163 KIAS, crucial to avoid structural damage.

• VNO: Maximum Structural Cruising Speed set at 129 KIAS, marks the upper limit for normal operations.

• VA: Maneuvering Speeds vary by weight:

  • At 1900 pounds: 90 KIAS
  • At 2200 pounds: 98 KIAS
  • At 2550 pounds: 105 KIAS

• VFE: Maximum Flap Extension Speeds:

  • With Flaps 10: 110 KIAS
  • From Flaps 10 to FULL: 85 KIAS

• Maximum Window Open Speed: Should not exceed 163 KIAS to prevent issues with cabin pressure and airflow.

• VSO: Stall Speed in Landing Configuration is 40 KIAS, important for safe landing approaches.

• VS: Stall Speed in Clean Configuration is 48 KIAS, relevant for maintaining controlled flight parameters.

• Maximum Speed - Sea Level: 124 KIAS, represents the fastest speed for best performance close to sea level.

• VR (No Flaps): Rotation Speed without flaps is 55 KIAS, essential for safe takeoffs.

• VR (10 Degree Flaps): Rotation Speed with 10 degrees of flaps is 50 KIAS, adjusted for shorter takeoff rolls.

• VX: Best Angle of Climb Speed is 62 KIAS, maximizing altitude gain over distance in emergencies.

• VY: Best Rate of Climb Speed at 74 KIAS, provides the highest climb rate over time.

• VG: Best Glide Speed at Maximum Gross Weight is 68 KIAS, optimizing glide distance in case of engine failure.
