Hi I have a quick question about the 737NG FMC.How do you enter a waipoint that is on the runway departure heading, at a set altitude but not at a set distance. For example, when you bring up some SID's, on the RTE LEGS page a waypoint on the runway heading that reads (3000) with the heading above it saying for example 320 degrees and TRK after it (refer to page 8-29 of the 08 FMC 737-678900). What I want to do for example is, depart Sydney Australia YSSY 34R and at 500 feet, make a turn 023 degreesto the right to waypoint HALLAS.I hope I have managed to make my question clear.Cheers,Nathan Ford

I am pretty much convinced there is no FMC that would let you create such a waypoint from the CDU. At least I wouldn't know one, correct me if I'm wrong. These points are specified in the SID that the systems stores in its database. The FMC can usually fly a number of different leg types, but that doesn't necessarily mean you could enter them on the fly, I'm afraid. :(

No name is correct. A fix defined by an altitude is called a floating waypoint because its position depends on your rate of climb. You cannot program floating waypoints through the CDU; however, they are easily inserted in a terminal procedure (sidstar file).Terry Yingling has an excellent tutorial on how to edit sidstar files at his site: http:\\planepath.comYou would use the keywords such as TRK 340 UNTIL 500

Thank you for your quick responce's.Cheers,Nathan

Have you tried putting a custom waypoint at that location, inserting it into the flight plan and then putting an altitude constraint on it in the plan and flying to it with VNAV? I would imagine that would do it.i.e putting HALLAS203/20 in the scratchpad and inserting it into a disco for example, to get a waypoint 20 miles from HALLAS that would put you on a 023 heading to HALLAS from it, which could then of course get an altitude constraint added on the legs page.Al
