What is the maximum gear extension speed (VLO EXT)?

• A. 240
• B. 250
• C. 260
• D. 270

Answer: (B)

VLO EXT is the maximum airspeed at which you may extend the landing gear safely. Keeping the extension below this speed ensures the hydraulic system, gear doors, and gear itself can deploy, align, and lock properly without excessive loads that could cause damage or misalignment. For the ERJ 175, the published limit is 250 knots. Extending at speeds higher than this increases the risk of incomplete extension, door interference, or the gear not locking, which can lead to gear issues in flight. So 250 knots is the correct maximum. Extending at 240 knots would be safe but not the maximum limit, while 260 or 270 knots exceed the permitted speed for normal gear extension.
