Airbus Flaps in Upper EICAS

[luisgordo]

Hi Folks,

I have a couple of questions regarding the flaps position / indication in the A320.

The positions are:
UP, 1, 1+F, 2, 3, FULL (6 total, though only 5 detents are provided - one common for 1 & 1+F -, which is selected differently if for take-off or for approach).

1.- I am using Project Airbus and I can't seem to get the flaps position accurately depicted in the Upper ECAM. I know this is defined in the A320.txt, and have fiddled with it to match what is defined in the corresponding Aircraft.cfg file, with no result. Any tips or things I have to be aware of?

The kind of problems I am experiencing are when flaps lowered once, no indication in ECAM, and when lowered twice it goes down to Flaps 4, for example, etc.

2.- How have you guys implemented the function of selecting either "1" or "1+F" depending on take-off or approach? Have you used pmSystems?

I can figure out the pmSystems part, without much problem, but I sure need help with matching the indications in the ECAM with the actual flap positions. Here are the FLAPS parts of the A320.txt (PM MCDU) and the Aircraft.cfg (FS2004) files:

Thanks Matt. I know those are the physical detents on the lever, but my problem is that the flaps position selected on the aircraft does not match that of the ECAM display.

Hi Luis

You can get some help in the manual (page 112-114).
You must define flap position names in relation with flap setting in FS.
you can monitor by cdu relation between flap settings in fs and flap position in magenta software and change the txt file.
by example in my b747400.txt:
flppos=1
flpset=1

flppos=7
flppos=5

and so on

Thanks Patrick. That's what I've done to this point (see my original Post). I matched the "flppos" in the A320.txt (PM MCDU) to the "flaps-position." values shown in the AIRCRAFT.cfg file of FS2004.

See my post above. Isn't it correct? Are flaps setting set elsewhere in FS2004? Maybe in the .AIR file?

Thanks.

[luisgordo]

Mmmmm, maybe the section to be matched is the [Flaps.0] ? (I was matching the [Flaps.3], marked as "actual flaps".

I´ll give it a try and post back...

When i say flap position in fs it is flap position of the aircraft (not cfg file)
you start wtih flap 0 and you press F7 key to increment one position and you monitor in the cdu (index, maint, monitor).
for each flap position in fs you adjust flapset in magenta text file.

OK Patrick. Got it straight now! Thanks.

I do have a problem, and it has to do with Flaps 1 position. In the Airbus 320 this means only Slats are extended, not Flaps, and hence the position showed in FS is Flaps 0 (even though the slats are extended and referred to in the AIRCRAFT.cfg file).

Hence, I can not get the Flaps 1 to show up on the ECAM display. (I know this position only makes sense on approach, not on take off, but since both Flaps 0 and Flaps 1 are referenced in PM as FLPPOS 0, it simply doesn't show up in the ECAM).

Any idea?

Hi
This logic with the correct function and displaying I have included in my AutoBrake Pro for Airbus as Flaps Control where you can jsut control the Flaps by writing the Position 0 to MAX to an Offset with value 0 - 4. The correct logic is done by the program for 1 and 1+F depending on Airbus logic.
