vilas - see post #20? These 'rules of thumb' are actually useless in this case since they only tell you the required RoC and what is needed is the actual, which is NOT available and is well out of reach of any line pilot until they see it when an engine goes pop - which is a little late if you are then over-weight for the required gradient.
IFLY does NOT need 'Rules of Thumb' - he needs performance charts for each SID at each airfield. a_d319 says they are not available and thus as OBN agrees, OEI procedures will not be adequate.
I find this extremely worrying if true. I am also concerned at the number of questions IFLY has asked (including how to fly a circling approach). It raises questions about the training he/she has received both for licence and type.
