Aviation safety and electricity

Whether you're piloting a small plane, a helicopter, a balloon or a hang glider, the dangers from overhead power lines are very real and can be fatal.

Before you take off

Make sure you know where overhead lines near to your departure airfield are. The CAA 1:250,000 map shows the major transmission lines, because of their height, but doesn't show other overhead lines (notably those on wood poles, which are more difficult to see from the air). You can also check in airstrip guides such as Pooleys for notes about overhead lines. Try and find out as much as possible about a new destination airstrip too: consider driving there first to inspect it personally. If you're practising low flying, keep a special lookout for overhead lines. Regularly refer to your CAA 1:250,000 map for lines near you.

Final approach and landing

Remember that overhead lines can be very difficult to see from the air. Look for a row of supporting poles or pylons. Poles could be hidden behind trees and a 'tee off' line may come away at right angles across your intended landing field. If you're unlucky enough to have engine failure, make sure you look out for overhead lines on your final approach and within your chosen field.

For gliding

Occasionally in winch/auto tow launches, the launching cable can touch overhead power lines, either from drifting across the lines after release or being dropped by the glider after breaking.
