RE: T/O On One Engine?

The key for trying any attempted t/o with less than all engines operating is not to use max power until you get above V<sub>MCG</sub>. Less thrust differential means you have a lower V<sub>MC_</sub>.

If you are going to call them fowler flaps, you would need to call them "single slotted fowler flaps" I think that given the 175 ft<sup>2</sup> surface area, the extra <7.5 square feet from the flap travel isn't that noticeable. Therefore, calling them slotted is probably more correct. I think the o...
