What are your thoughts on intersection departures? Are there any procedures/rules that prohibit when you can use them, other than the obvious need for a full-length TO due to weight?
I was always trained that runways are your friends and you would rather have more than less of them on takeoff. However, I noticed that RJs were departing 14L using U2 at ORD on a rainy night yesterday. On my very lightly loaded 777 the captain accepted an intersection departure out of DOH last month.
I realize that pilots have to make a judgement between getting out expeditiously and having more runway below them should things go wrong. Just curious as to what goes into the decision to accept, even request, an intersection departure.
