Vmid a new call-out speed on TO and Landings

[BEagle]

I'm not convinced that the folk who:

- Use incorrect TOW;
- Ignore the effect of tailwind on RTOW (AF Concorde accident...);
- Use incorrect contaminated RW procedures on take-off or landing;
- Touchdown long and hot on very wet RWs;
- Don't understand 'slippery when wet';
- Don't check they're on the right RW:

would be saved by any other gizmos than already exist.
