Hi,
here is the STAR for the 9L approach at LHR for example.
I have circled the holding pattern.
where does it say the altitude you should keep.
and also, how do you know how far you should travel the "straight" on the loop before turning to make the other side of the loop.
finally, when filing the flight plan... how do you know which STAR approach to use if there are multiple possible STAR approaches.
do you just choose the most suitable depending on your approach?
thanks
