V-speeds

Groups B/D: First Year Beginning

Essential Questions

• What is a v-speed?• What does the “v” stand for?• What purpose do v-speeds serve and why are

they important?

What are v-speeds?

• velocity speeds• speeds that are common for all aircraft and specific

for each model and type (ex. 172K is different than 172N)

• We’ll be learning: Vx - best angle of climbVy - best rate of climbVr - rotateVa - maneuverVso - stall dirtyVs - stall cleanVfe - flaps extendedVne - never exceedVglide - best glideVno - max structural cruising

How do v-speeds work?• Vx = best angle

• pitch up - lower airspeed

• Vy = best rate

• pitch down - higher airspeed

How do v-speeds work?

• Vrrotate253: 55 kts

• Vamaneuver253: 82-99 kts
