Landing gear extension and retraction are usually part of the standard operating profiles.

On take-off, once there is an indicated positive rate of climb, the flying pilot will call "positive rate gear up" the monitoring pilot will select the landing gear handle to the up position.

For landing, there are more variables. For a landing in reduced visibility requiring flight solely referring to the instruments, the landing gear is usually extended around the final approach fix (around five miles from the runway). This can vary depending on the type of approach being flown. In good visibility when a visual approach can be flown, the extension can be delayed somewhat. During a visual approach from downwind, the gear is often extended when turning on to the base leg.

Gear extension during visual conditions can also depend on if it is needed for additional drag to help slow to landing speed.
