What rule of thumb should be used for a level off lead point when the VSI is less than 2000 fpm?

When considering the level off lead point for an aircraft when the Vertical Speed Indicator (VSI) shows less than 2000 feet per minute, using a rule of thumb of 10% for a smooth transition is advisable. This approach helps ensure that the aircraft levels off gently and avoids abrupt changes in altitude that could lead to discomfort or loss of control.

When leveling off, initiating the transition at a lead point that is 10% of the vertical speed provides a systematic way to predict when to begin the leveling process. For instance, if you are climbing at 1000 feet per minute, starting to level off approximately 100 feet before reaching your target altitude would allow for a gradual adjustment to level flight. This promotes a smoother flight experience and better adherence to altitude restrictions, especially in busy airspace.

This method is effective in maintaining control and stability during the transition to level flight, making it a preferred technique in flight operations.
