Hi AllI am having trouble with the above , i am writing out a plan in the fmc but when i press ARR/DEP for LHR i get error EGLL 0252 unknown (i think its that number) for DEP but a full list for ARR yet i have put in the latest AIRAC only 5 mins before.What am i doing wrong?Thanks in advanceKarl BAV0221

Karl there is probably an issue with the AIRAC cycle. Take a look in your SIDS/STARS folder and see what is there for EGLL. Mine is located at C:Program FilesMicrosoft GamesFlight Simulator 9PMDGSIDSTARS. Yours may be similarly placed. You may be able to download an EGLL SIS/STAR file to get you going. Either that or roll back to the previous airac cycle and see if that works.
