Embraer ERJ 145 Flight Simulator

Welcome to the world of home built Embraer simulators

Mk VI Pedestal

Well the new pedestal is complete.

Highlights:

New structure (at last at the right size!)

New throttle and Gust Lock at corect sizes, and linked to throttle - 2 pots from my CH TQ, and gust lock a microswitch.

New Speed Brakes direcly using the arm of the CH pot located underneath.

New Flap lever, using CH pot lever underneath, and MDF detents

New Parking Brake using steel tube and angle iron, linked to microswitch, with MDF detents (lift and turn)

Electronics bay with access panel, containing button and axis connections and FDS card.

Added joystick buttons on the pedestal for multifunctions, not yet available.


The pedestal has a new structure, slightly lower than the Mk4 made from 8mm MDF. I retained the original TQ main structure, but made new levers and handles using PVC pipe, with MDF fillers cut using a drill saw - this makes fitting the TOGA buttons and wiring easier.

The back of the lever is machined out using a router to allow the cabling, and then filled using car body filler. The throttle levers connect to the pots using alu links, and the post are positioned at the rear of the main structure, and are adjustable using the fitment to the base board.

The gust lock is made using steel flat bar joined at the top by a steel tube, mounted on the same axis as the levers (an 8mm threaded rod) and is free rotating, but only operates over the front 90º of the quadrant. A cross bar mounted about half way up contacts a limit switch when the lock is in the free position.

The top is made from 4mm perspex, bent using a heat gun, and is liiuminated using LEDs between the levers. The finishing touch is the rubber gaiter, cut from a bicycle inner tube, and glued to the MDF beneath the cover.

Cabling for the buttons and the FDS interface card sit at the rear of the pedestal, and are accesable via an inpection panel.

Connection runs out through the open front ,and connects with the interfaces and PCs mounted behind the MIP.

 

The nose wheel steering wheel on the left pedestal. is linked to a potentiometer and calibrated using FSUIPC.

In front is the sound control for the Soundblaster card, behind that the ashtray and drinks holder,  then the GoFlight ATC unit ( well, half of it, the other half with the LCD and knob has been relocated to the pedestal.

 

Here is the interior of the pedestal showing the throttle levers and pots. After the addition of the wires for the buttons, it looks a bit more crowded.

Also added was a dummy compass, with a curved perspex front, curved letters and an LED in the centre. This does not move, but adds to the "eye candy! when looking around the deck.

MK IV Pedestal

The pictures below show some of the features of the MkIV pedestal - the CH unit has been moved further back, and linked using pushrods, and a new heavier duty throttle unit added.

This gives a more positive feel, and although not 100% scale, is certainly an improvement.

The MkV is on the drawing board, where I plan to discard the CH unit completely, and use new slider pots and a different controller card to give further enhancement.

 

The top of the unit now has realistically sized panels, fitting standard racks, and will feature new controls - trim, FADEC, TOGA and probably the coffee maker.


With CDU

 

 

I added an FDS Boeing CDU to the setup, in the absence of the Honeywell FMS.

The fitment is temporary (what isn't!), and uses an old PC power unit to give both 5V and the 12V required for the display.

The unit is connected via S video to a Nvidia 7600 card on the pc running the PM CDU software - an excellent setup!
