I made a small tutorial for the 787 to cut it down to the basics - hope you like it

Having an altitude issue landing the 787
I am using autopilot, hitting the FAC/LOC button on approach, then once engaged I hit the APP button for G/S. I am unsure why, but it will often be too high for the runway, and I have to go-around and do a manual land, any ideas?
Welcome aboard! I have not viewed the video above in this post of 3 years ago so will respond instead to your situation with a few questions, if you please. These might not be enough to get to an answer but will help you think through what may be an issue.
What kind of approach procedure? ILS, RNAV, something else? And too high by how much?
Autothrottle on at the time? Airspeed target on the approach? Airspeed set by you on the panel or airspeed managed by the FMC/FMS?
There are a lot more questions one could ask but why not let’s start here and see where it goes?
Hi, thanks for the assistance.
Yes its an ILS approach.
I am high by about 500-1000ft, and at times have been 500ft under.
Autothrottle is on most of the time, I do turn it off at 500ft.
Airspeed target on the approach is at around 155kn, although sometimes at 175kn, that seems to be set by the Autothrottle.
I thought by setting 30/152kt in the approach ref took care of the speed on approach?
Ok, ILS 9L at CDG is a standard 3 degree glide slope so nothing unusual and the App Ref page looks normal, so let’s work the problem a little further. Backing up a bit, are you on 2020 or 24, PC or Xbox, and any controller peripherals?
Altitude set on MCP is something like 4,000’ to intercept the ILS?
At what flap setting are you intercepting the GS, what kind of flap schedule up till then?
Any challenges with weather, winds on the approach or over the runway threshold?
Are you hand flying the ILS and if so, at what altitude do you take over from the A/P?
Do the altitude deviations, high/low on approach, happen on a full Autoland approach?
I’m of course not sure if this way of working the problem is helpful to you, so if not, LMK? Cheers

I have 2020 installed, on a PC and using an extreme 3D Pro joystick. I have a yoke setup, but its a little bulky for the desk.
I start adjusting the flaps at 4000ft as the GS engages.
4000alt - 5Flaps
3000 - 10
2500 - 20
2000 - 30
Happens on most Autoland approaches, if I can tell its too hot I try a manual land.
I tried one just now, was at 233kt at 2000ft, its really annoying as I have sat waiting for 30mins to see how the landing plays out.
I think this is helpful, thanks for your help in advance.

Latest update:
Seem when I drop the gear and flaps going into G/S, its a more consistent and sits at 157kt through landing…2/2 landings so far.

Right, with this flap schedule the Dreamliner is carrying way too much energy/airspeed for a stabilized final approach to landing. We can improve upon this and you will find landing much more manageable, either on A/P or by hand.
I’m not in the sim right now, so this will be a little loose and you can improve upon it for sure.
- Start reducing airspeed along the Standard Terminal Arrival (STAR) procedure and/or…
- Plan your descent to fly no faster than 250 just above transition altitude, 5,000’ in France?
- Plan to fly below 240 below transition altitude, reducing speed before the Initial Approach Fix
- Look for the flap speeds on the airspeed tape, this not altitude is your flap extension schedule
- It may help to take over Airspeed from the FMC and set on the MCP to get the hang of this
- Once you are comfortable with the above, you can set your airspeeds in advance on the FMC
- If you are using ATC, you may have make requests/ignore stuff to get a stabilized approach
- I suggest flying without ATC, multiplayer and/or traffic on to practice final descent/arrivals
If one thinks about a busy airport like CDG, aircraft will often be stacked up on the ILS closely spaced. They need to fly about the same airspeed to fit into traffic flow, therefore, you will be close to Vref +10 at 4,000’ to intercept the ILS. That suggests 160kts and flaps 15-20. Gear can go down intercepting the GS and final landing configuration, flaps 25-30, by the 2,500’ call out. in 2020, I want landing configuration done, landing checklist done, by 2,500 and before disconnecting the A/P. I leave A/T on till over the runway threshold, but you can play with that.
Why not play with this on a few flights then ask questions, you will sort it out quickly, I believe!

I will do that. I really appriciate your advice
The G/S indicator display will appear automatically when detected or is there a button to turn on like airbus ILS button .
I referring to those dots and diamonds indicator
