In principle, the answer to this question is "yes". Inside buildings, however, the compass may be severely disrupted or the GPS may fail.
It is important to switch to manual mode (i.e. without GPS support) to avoid surprises if the drone switches between GPS and manual mode on its own. It is also advisable to check or deactivate the copter's return function so that it does not fly above the ceiling height if the connection is lost or the battery voltage is low, for example. Many systems now also utilise optical sensors and can therefore maintain their position.
The obstacle detection often integrated into drones can lead to difficulties when flying through narrow spaces. In this case, experienced drone pilots should switch this off and fly very carefully. The pilot should be confident in his abilities.
Without these numerous support functions, the safe flight of the drone depends largely on the pilot's practice and skill. This can be demonstrated by passing a
The interior of buildings does not count as airspace and is therefore not subject to aviation regulations.
