How high do I fly? It very much depends on what I’m flying.
If it’s a slow, quiet aeroplane, such as a J3 Cub or Tiger Moth etc, I normally fly as low as I legally can, taking into consideration potential forced landing territory, Rule 5 and any Permit to Fly conditions etc. If it’s a high performance or noisy aeroplane, or one that’s going to be difficult in a forced landing scenario, the height goes up dramatically, so I’ve got a better chance of picking a suitable field if the fan stops.
But I do ALWAYS fly at odd heights (1650ft, 2300ft etc) to reduce the chances of meeting soembody else flying exactly round numbers....
