Rn-time error 55 when entering a route

[Ray Proudfoot]

I'm running build 400 of the Boeing CDU and I'm having great difficulty entering routes without encountering run-time error 55 - file already open.

Here is one example...

EGKK
Rwy 26L
LGAV
Rwy 03R
SID=BOGN1M

I press Route and the display shows BOGN1M.BOGNA in LSK4L and BOGNA in LSK4R.

I then press LSK5L to show available routes and select UN615.XAMAB and then press LSK5L to insert it into the plan.

I then press Next Page and press LSK1L. Nothing happens. the display remains blank. I wait 15 seconds and press LSK1L a second time.

BANG! Run-time error 55 - file already open.

This is very frustrating. I would love to enter my routes using this method but it just isn't reliable. I've just installed cycle 0813 but it has happened with previous cycles too.

Do I have a corrupt installation or are others suffering the same problem? As a programmer it would help if the error message was a bit more helpful. What file is already open? And why can't the routes be retrieved?

Hi Ray,

only see this issue one time at entering a route.

I entered Airway and then the Waypoint, then CDU crashed with Run Time Error 55.

Entering complete Waypoints, without Airways, all was ok and no crash.

Route:

RTE VIA: DEP NSFA
GOTSO-GOTSO / H969-TUT / A212-PUPIS / G347-DATBE / VECKI6-VECKI /(APT-PHKO)

Latest Builds from PM-CDU 400.

Best regards

Thanks Roland.

And what do you do if you don't know all the waypoints required? You're working around the problem. Have you reported it to PM as Jonathan has requested?

Something in the data must be wrong but the error is simply caused by trying to open a file that is already open. This should be a trappable error and shouldn't cause the CDU software to crash. So there are two problems - cleansing the data and preventing the error.

Navigraph supply data for other CDUs such as PMDG and Level-D. I don't know if this problem also occurs with their systems.

It's not as if this is some obscure jet route. I've had it happen twice now in UK airspace so something is clearly wrong somewhere.

Hi

I will continue to watch for the error, initial I can not create - perhaps someone will post an *exact* procedure, step by step to create it.

Here are the steps to creating the error. 1R means LSK1R; 3L means LSK3L. RTE means the RTE button was pressed. All LSK presses are in red.

Press RTE twice.
Press Flush.
Type EGKK and press 1L.
Press 3L and choose 26L.
Type LGAV and press 1R.
Press 3R and choose 03R.
Press 6R - Activate.
Press EXEC.
Press DEP/ARR.
Press 1L - DEP.
Press 2L - BOGN1M.
Press EXEC.
Press 6R - ROUTE.
Press 5L.
Choose 1R - UN615.XAMAB.
Press 5L to insert UN615.XAMAB.
Press Next Page.
Press 1L. Nothing happens. Wait 15 seconds.
Press 1L again. Run-time error 55 - File Already Open.
Press OK. CDU crashes.

No, I haven´t reported to Jonathan cause I have in the moment bigger problems (2 Computer with Hardware defect, so I can´t fly and test). Some CDU 400 Problems by entering Airport POS the CDU enters DGTK as airport. Hope to get new hardware next week so i can build up my simulator and test.

I plan my route over http:/vatroute.net or FOC2003 so I get always plans with Jetways or the complete routing. I know it´s a workaround and I perhaps there are problems with the data to recompose Jetway and Waypoints.

Hi Roland,

The DGTK problem is because the CDU isn't 'seeing' FS. That airport is the closest to lat 0. long 0.

Anyway, I seem to be able to find these runtime problems at will so hopefully Jonathan can replicate it and then fix it. If he can't then it suggests I have a corrupt file. But which one?

[RGroebl]

Hi Ray,
thanks for your information about DGTK.

I don´t think you have a corrupt file. I think there is something with the navdata and the recomposing of Jetway and Waypoint. There is also sometimes problems with SID´s don´t calculate FL and Speed, after inserting an FL or Altitude (at example /4000A) all is calculated correctly.

There must something wrong with the imported data.

Hi Ray

I don't get a runtime error with that procedure - tried it three times. Can you explain to me what you are expecting to see on the RTE page 2? May be I got lost here...

Do you have VIA and TO shown on the RTE 1 page?

BTW - this is using most recent Navdata cycle, but previously I have been using April / July & August without problems. This one is Nov/Dec

Pictures are the best way of showing my situation. The first shows the situation after I have entered the SID and the first sector - UN615.XAMAB.

On the second page I would expect it to be blank initially but when I press 1L I'd expect to see several routes to choose from. Can you show a screenshot of what you're presented with please?

I am also on the latest Nav cycle installed yesterday. I extract the required files and place them in the main CDU folder. That's what the readme say's to do. Do you also do the same?

I'm attaching a screenshot of the contents of CDU\Data.
