So this discussion comes about from a recent night VFR CFIT accident. The facts are not all in yet, but it appears a close temperature dew point spread of 2 degrees C combined with already low ceilings may have been a major factor.
It makes sense that night flying is more hazardous than daylight flight. I don't remember the source (maybe AOPA), but forced landings in daylight have a 90+% survival rate, while at night it goes the other way and the survival rate drops to like 10%. Does anyone know where this comes from or if it is even close?
