I wasn't too sure where to post this as it's comprehension, rather than technical, but here goes...
I'm working through some aviation related physics questions in preparation for the ATPL theory and have come across the following statement.
The fore and aft distance between the two main wheels and the single tail wheel of an aircraft is 8m.
Maybe I'm missing something here but, what on earth does that mean? The question is about calculating forces on the wheels so I'm thinking the simplest configuration is most likely.
