I did a flight from MEL (YMML) to SYD (YSSY) in P3Dv2.

This was the route: RWY16 DOSEL8 Y59 RIVET RIVET1 ILS34LY SY - SID DOSEL8, no TRANS. STAR RIVET1, no TRANS. Approach ILS34LY, TRANS SY.

( 984) ROKDL SALLY DOSEL EBONY ARRAN NONUP TARAL CULIN RIVET TAMMI BOOGI DUDOK NASHO VECTORS SY D178N (INTC) SY/16 SOSIJ FF34L RWY34L (500 ) (3000 )

I then went to LEGS page 4/5, copied SOSIJ (LSK L5) to the scratchpad, then pasted it over VECTORS on page 3/5 (LSK L5), then activated & executed the route.

The Takeoff was fine. The Climb was fine. The Cruise (FL400) was fine and the descent to waypoint TAMMI (the second waypoint in the STAR). From that point on, it was a mess. The 777 never descended below 8000 feet and I ended up being 4000 feet above the G/S upon arriving at waypoint SOSIJ! So I did the stupid thing of turning the A.P OFF and manually landing (JUST!) on the runway threshold. Common sense says I should have done a Go Around, THEN returned to capture the ILS/GS and land! If the passengers had been real, they would have wated to murder me for such a sh*tty job on the landing!

Anyway. That was a case of messing with the STAR/TRANS for the approach and landing, and the 777 did not like it at all! :(

So I redid the flight with a slight difference. This: RWY16 DOSEL8 Y59 RIVET RIVET1 ILS34LY - SID DOSEL8, no TRANS. STAR RIVET1, no TRANS. Approach ILS34LY, I did not select TRANS SY for this attempt!.

( 984) ROKDL SALLY DOSEL EBONY ARRAN NONUP TARAL CULIN RIVET TAMMI BOOGI DUDOK NASHO VECTORS SOSIJ FF34L RWY34L (500 ) (3000 )

I did NOT change the route at all (no copying, pasting, or overwriting the waypoints). Everything worked very well during the second flight! Because the second route had the VECTORS after NASHO, and before SOSIJ, so I used HDG HOLD, then HDG SELECT to turn towards SOSIJ after about 1 minute on the VECTORS heading (154 degrees).

By the time I reached BOOGI, the 777 was at ~7200 feet, by NASHO it was at ~5200 feet, and by the time I reached SOSIJ, it was actually at 4000 feet, exactly where it needed to be. The only inputs to the MCP were setting the ALTITUDE  to 9000 for TAMMI (/9000B), the 6000 for BOOGI (/6000A), and then 4000 for SOSIJ (/4000A) and also slowing down to 230 knots just prior to reaching SOSIJ, which doesn't have a speed constraint, only an altitude constraint. These were the exact same inputs to the MCP as I had done on the first flight which had failed miserably.

I wanted to share this to show that just following the route works fine. I recorded the second flight with FRAPS, and hope to put it up on YouTube later tonight. It could be a LONG video (about 1 hour), unless I can figure out how to speed it up, or cut out, the cruise portion of the flight.  :-/

THE FOLLOWING VIDEO IS NOT A TUTORIAL FLIGHT! But feel free to make use of any info you find helpful for flying the 777 Captain for P3Dv2 (and FSX). ;)

Note. Sorry about the quality, it's not very good. I messed with FRAPS settings and reduced them too much. :(
