Re 747 cdu
I have a strange problem with the CDU pre flight setting. I wish to input all the boxes in the CDU pre-flight. In the cdu config file the pre-flight is set to "full" but when you go into the cdu the boxes are set like preflight is off. If I go to the settings page and press the pre-flight button - the empty boxes appear (ie - switch preflight back on). No matter what I do though the cdu will not save this setting or probably just ignores it as if I check in the config after exiting the cdu, the correct setting is there.
Is this a known bug?
Many Thanks again!

You want to use Pre-Flight = Full not on....Bob Reed

In the config file it is set to "FULL" but it always fills in the boxes for me. If I then go to the config page within the cdu program it says "preflight- full" - strange. So then I push the button once and it clears the boxes.... but I don't want to have to to that every time of course.

Are you referring to the Perf Init page? I have Preflight=Full and all the boxes on the left are blank except for Fuel. That is how I would expect it to be.
On my earlier point the Menu / Display screen shows the Case setting as Brown when Grey is what is showing. You press the button to change the case to Brown. I would have expected it to show the current colour.
Maybe some of that logic has made it into other menu selections?

Thanks for the reply.
First up - yes - I'm reffering to the perf init page.
Yes - I think that's how the logic's working. I.e. on the settings page it says pre-flight - full - so I press that button and the boxes are emptied. Therefore I'm thinking that by pressing the button on the settings page it is switching ON preflight=full. That's great and works as expected.
However, within my cfg file for the cdu, under preflight, this is set to preflight=full. Therefore, for some strange reason it's ignoring my preference in the .cfg I believe....weird.

With the preflight option on in the B744 cdu pages, V speeds etc has to be confirmed or corrected.
Also entries for flap retraction scheme must be entered.
Syntax in ini is "PreFlight=Full"

If the display already say's Full then by pressing PreFlight you are changing the value to either On or Off (the two other settings I believe).
If the INI entry say's FULL then you don't need to go near that option. The Perf Init screen should be all blank except for Fuel. I just press the top-left button on Perf Init and the aircraft weight is entered. Is this what you are seeing?
Sorry for being a little vague with my descriptions but the above is all from memory. My CDU is on another PC.

My ini flile says - Preflight=Full.
However, on my Perf init page, it fills in the boxes for me. (weights etc).
I do not want this of course, I wish to fill in the boxes myself.
Why I mention the settings pages is because it is the only way I can get the boxes to clear..
