CFIT, otherwise known as
Controlled Flight Into Terrain is a phenomenom that involves an accident in
which aircrew flying a perfectly good (at least flyable) aircraft into the
ground. What do I mean. CFIT covers those accidents that involve aircraft
impacting the ground due to incorrent altimeter settings, loss of
situational awareness, or running out of gas (to name a few). Although it
is hard to imagine CFIT accidents, they do occur. If you fly IFR or at
night, this should be of interest to you.
The Flight Safety Foundation
put together an incredible package covering Controlled Flight Into Terrain (CFIT).
In their research, they analized 40 CFIT accidents that occurred from
1986-1990 to see if any trends were evident. Their findings were pretty
clear. Here is a graphical display of their findings. These images come
from the FSF CFIT package but I think it is worthwhile to show them on this
site in the interest of Flight Safety.
So which IFR approach has the
greatest risk of CFIT associated with it? Here is what the FSF uncovered...
