What is the maximum gear extension speed (VLOE) for the ERJ 170/175?

The maximum gear extension speed (VLOE) for the ERJ 170/175 is crucial information for pilots, as it defines the highest airspeed at which the landing gear can safely be deployed. In this case, the correct answer is 220 KIAS.

When the landing gear is extended, significant aerodynamic forces act upon it, and if deployed above the VLOE, it could lead to structural damage or malfunction of the gear mechanism. Therefore, understanding and adhering to this limitation is essential for maintaining the safety and integrity of the aircraft's systems. The 220 KIAS value ensures that the gear can be extended safely without introducing excessive stress on the components, which is critical during operations involving changes in airspeed, particularly during descent and approach phases.

The other options represent speeds above the safe limit for gear extension. Operating at these higher speeds during gear deployment could potentially result in a failure of the gear to properly lock into the extended position or adverse aerodynamic effects. Thus, adhering to the specified VLOE of 220 KIAS is vital during flight operations.
