What is the VZ (Vy) speed for best rate of climb on the ERJ 170/175?

The VZ (Vy) speed for the best rate of climb on the ERJ 170/175 is indeed 255 KIAS. This speed is critical for pilots to know because maintaining it will allow the aircraft to gain altitude in the shortest time possible, which is particularly important in situations where a rapid ascent is necessary for terrain clearance or airspace restrictions.

Climbing at this speed optimally balances the lift produced by the wings against the drag, allowing the aircraft to maximize its vertical speed. Additionally, being aware of the correct VZ speed is essential for flight safety, as flying too slowly may increase the risk of stall, while flying too fast could increase the drag, resulting in less efficient climbs. Therefore, knowing that 255 KIAS is the appropriate speed empowers pilots to make informed decisions in climb scenarios.
