As every schoolboy knows the English Channel is 21 sm wide at its narrowest point, this is 18 nm. I have just checked this on the map and it is bang on and there is no restrictions on this route. If you are out by this much with your planning ……
At 130kn that is about 8.5 min from coast to coast. I know my maths is right so it is up to each pilot to do the sums and allow for wind for the point of no return and calculate the amount of time out of gliding range. I do not fly a PA28 so I have no idea how it will relate, and there are many versions.
Most aircraft, correctly ditched, will float, but not all, so yes I do hope mine is one of them.
