What is the altitude clearance needed to clear a 50 ft obstruction if conditions are high temperature and low wind?

To determine the altitude clearance needed to safely clear a 50 ft obstruction under high temperature and low wind conditions, it is important to consider how temperature influences aircraft performance. In high temperature environments, air density decreases, which negatively impacts an aircraft's lift capabilities. This often necessitates a greater altitude clearance to ensure safe passage over obstacles.

Typically, the required clearance can be calculated by applying a standard altitude that accounts for the obstruction height and the performance adjustments needed under varying conditions. For a 50 ft obstruction, a commonly accepted safety margin is applied, which includes overall terrain effectiveness and obstacle clearance at a safe altitude.

In this case, an altitude clearance of 800 ft provides a cushion above the 50 ft obstruction while compensating for decreased performance associated with high temperatures. This allowance ensures that the aircraft maintains sufficient altitude without risk of collision under the specified environmental conditions.
