Workday 14th April 2018

LCP
Before lunch it was more rubbing down of the internal walls of the cabin, currently the section above and to the sides of the display console. The repainting of the internal walls will refresh the look of the cabin as the existing paint is ‘aged and discoloured’, note the difference in colour between the prepared and original sections of the cabin wall below.

The holes used for the securing bolts for the Argus 200 remain as do the scratches resulting from installing the MK2 computer racks and console. The colour will remain ‘cockpit green’ as it is easy on the eye, according to the RAF in 1964. For interest, as you can see, the internal colour of the Swiss LCP’s is a light grey, this is a Swiss MK2A LCP taken two years ago. I know, it still looks brand new!

The afternoon was spent on recovering the simulator from faults, namely a U/S memory (Store) card and a U/S Pixel Store from the display system. The cards were replaced with spares, the memory card last week and the Pixel Store on Saturday. Unfortunately the display driven by the faulty Pixel Store still had a loss of Vertical Sync (the monitors are mounted 90 degrees from normal alignment) so the picture drifted across the screen with what looked like some flyback breakthrough.

Time was also spent on using a number of Argus operating system commands to list and interrogate files, all with the aim of helping us understand what happens and in what sequence during a boot.  One operating problem is that the software gets locked in a loop at boot up if errors occur with the display and co-processors. We are receiving some expert help on the software as our knowledge on the Argus 700 software is lacking – to put it mildly.

The simulator was left in a serviceable state.

Further work was carried out under on the cabin chassis, it was Dave’s turn this week! It was obvious that removing the wheels would assist in this task and the accompanying images show the nuts being slackened on one wheel, leverage required!

Dave was able to remove one wheel but the others will require a lot more torque to shift them! The second image shows the wheel hub exposed after removal of vegetation and a good wire brushing.

For information, tghe tyres are Dunlop Truck and Bus brand size 10.00-15. Obviously the age of the tyres means that they are starting to perish, we don’t need new tyres as the cabin is not road worthy, nor will it be, but second hand tyres that are not perished are sought – anyone able to help please?
