Most CFIIs around here
require pilots to practice zero/zero take offs by putting the hood on
our students before applying power on take off. Its not that we want
you to take off in zero vis, its because you could be rolling down the
runway and encounter it.

Question from the uneducated he in this case, do you keep the plane
from running off the runway by, well, by what ... the ILS? Is it good
enough for that?
