What measurement should a remote pilot use when considering tower heights?

  1. MSL

  2. AGL

  3. Both MSL and AGL

  4. None of the above

The correct answer is: AGL

When assessing tower heights, remote pilots should consider measurements taken Above Ground Level (AGL). This measurement reflects the height of the tower relative to the ground where the tower is located. Since drone operations are typically conducted at low altitudes in close proximity to structures, measuring heights in AGL is crucial for ensuring safe flight operations and avoiding obstacles. Mean Sea Level (MSL) is concerned with the elevation of points relative to sea level, which can be less relevant when evaluating immediate hazards like towers in the vicinity of the drone’s operational area. While MSL can provide useful elevation data in certain contexts, AGL specifically addresses obstacles encountered during typical drone operations. In this context, focussing solely on AGL ensures that remote pilots maintain a clear understanding of the potential risks posed by nearby towers, allowing them to make informed decisions about flight planning and obstacle avoidance.
