Hi Terry, hello all A lot has now been said about the 50 ft rule but I'm surprised that no one has pointed out that this can be outright dangerous. Consider the case where a heavy open class glider (touching down at 55 kts) is forced to outland in a rather small paddock. Compared to an

For past 20 years I use the units chair height, table height a and roof height. Also when power flying I have no issues with with nautical miles for distance as theside of every map has the scale. Also a young kid learning gliding taught me the conversion from kts to kph you multiply by 1.852
