technology will never beat a sectional chart and knowing how high the terrain is
(but yes, it helps)
Yes it will, because I'm where the terrain is, and there are sure a lot of flight into terrain accidents around here, because the pilot has become confused for a few seconds in IMC conditions and can't get a mental bearing on the situation.
When you've got four or five seconds to figure what is what, a good moving map beats the crap of trying to figure out where you are on a sectional.
The accidents I refer too, are not a case of maintaining minimum altitudes over terrain. They are caused when descending to land, departure climbs, or missed approaches. All in IMC conditions.
These accidents have ranged from plain stupidity, to white outs, clouds in darkness, severe loss of altitude while trying to capture the ILS, or losing situational awarness while attempting a missed approach. The brain is scrambled, or just not thinking, and no time left to be looking at a sectional.
