In addition to the previous chapters relates to the ‘Flight Deck Sound System", I wondered how much the ‘SPL’ (Sound Pressure Level) is in a B737-800 Cockpit.

Some allied B737-800 pilots at Ryanair have a while ago for me the test on the sum taken by a measurement to do on cruisehoogte (FL370).

This measurement is done via an App on their IPhone and not using a calibrated meter vibration. So the result is not 100% correct but it gives us an idea.

Further info regarding this test is found on page http://www.flightdeck737.be/pc/sounds/flight-deck-sound-system/

Have tacticle Sound or ‘tangible sound’ is an interesting addition to the homecockpit.

By vibrations of the different mechanical parts or situations, this gives again an additional ‘real flight’ feeling in the cockpit.

Sounds impressive ‘Flight Deck Audio System. It is better than cockpitgeluiden’.

The humming noises that can be heard from the pc speaker when the first versions of MSFS is already long past time. The current hard - and software are currently offering a lot of possibilities and perspectives to which a realistic audio-setup in a cockpit verwezelijkt can be.

The setup of a Flight Deck Audio System is also a very important factor to a ‘real’ feeling to have in a cockpit.

Last Saturday, I am the After Overhead from the FlyEngravity. In contrast with the Forward Overhead I had there this time not a lot of work. Everything was already assembled and ready for use.

The only job for me was just the AFT OVH confirm in the coverbox and connect it to the FWD OVH.

After the tinkering of the metal frame to which the overheads need to come hang out, and the confirmation of the FWD Overhead it is time for this to be operational.

The cable routing goes through the metal bracket of 80 mm. This is for the 12V-power supply with adapter (which I extended to do), the cable of the backlightverlichting of the dummy gauges, the ICS USB cable and the cable of the overhead spotlight’ (Flood light).

After making the metal frame for the OVH's now turn to the FlyEngravity-windows to mount against the support frame.

Previously I have already measured how this B737-windows must be installed at this frame, i.e. the height t.o.v. of the FWD Overhead, the pre-drilling of the attachment points against the middenstut and the brackets in the rear. After the installation, you must all the windows on the top level.

The final stage in the making of this metal frame is the confirmation of the overhead.

This means the coverboxen (ovh-frames) to the support arm.

To this frame, in other hand, there are 5 connections, or links :

• Connection between steunvork and MIP-frame;
• Connection between front steunvork and support arm;
• Connection between the suspension arm and the transverse strut;
• Connection between the transverse strut and upright steunbenen;
• Connection between the upright steunbenen and the B737-side windows.

The frame is made of iron installation/meubelbuizen of 40mm x 40mm x 3mm and 80mm x 40mm x 2mm.
The tubes are purchased at Hardware Store Vanbeeck in Leopoldsburg.

The whole metal structure is composed of 5 parts.

The painting of the frame at this time is not done with brush and roller but with a simple painting system had that I bought in Aldi.

On the Internet have different dimensions. I have the dimensions held that to be found on the website of Markuspilot.com.

I started with all the draw out on graph paper. First, the MIP platform scale and then the support frame.
I have a few ‘goals’ or referentieafmetingen respected with the rest of the construction should follow in the further drawings.
