Performance-MEP1 takeoff climb data
in the CAA performance manual for JAR FCL exams CAP 698, Feb 2002 issue;
page 30: there is an example they give to calculate distance from the end of TODR to 1500 ft. and rather than print it all, will hope that some others studying for the UK tests toward the JAR ATPL will have the same manual to open;
"Distance to cloud base= 350/1660 x 90/60 x 1.3 = .42 NM"
i can understand everything on the entire page, except for the
"x1.3"
like wise on page 31, another example; "distance to cloud base=350/1500 x 124/60 x 6080 x 1.3=3811 ft"
i don't understand where the "1.3" is coming from in both cases.
perhaps i cannot see the forest for the trees.
and while we are on the subject, i am finding these charts most difficult. such precision required on such small charts! and their example on page 24 at the bottom, "3370 lb. Using 2000 ft" i can't even get close to that when following them through.
i thought meteo was going to be bad. but i surprized everyone and passed it first time. but this performance really scares me now!!!
