Is the INITIAL ALT of an SID used in simbrief and where is that variable?

Trying to find the data - its on the charts but I dont see it in the flightplan. Thanks.

No, SimBrief does not account for SID and STAR altitude restrictions yet.

But also, the initial altitude would not really be featured in the OFP in any case.

You would find it on the chart and/or it might be given to you by air traffic control (they’re allowed to amend the initial altitude in some cases, and some SIDs have an ATC-assigned initial altitude as indicated on the charts), and the pilot would manually write it down somewhere along the rest of the departure clearance.

Regards,

Most professional flight planning systems don’t consider it (especially the older ones) - for example on some SIDs departing N out of RJAA there is a hard altitude of 7000 until passing a given fix; some systems will cap the altitude until 7000 until passing that fix then climb accordingly. It doesn’t impact the ATC filing at all, but the gas for the climb reflects the 7K altitude restriction, so the climb time/distance/fuel is more realistic. Every time I have jumpsat out of RJAA on that SID (RJAA-LFPG 777F), we dutifully maintained 7K until passing that fix, then ATC got creative with us.
