DESCRIPTION

The After Overhead is together with the Forward Overhead (and, of course, ProSim737) the nerve centre of the aircraft. Through both of these panels, all systems are activated and checked.

After Overhead (AFT OVH) is not used as frequently as the FWD OVH and is usually discussed as a control system at the beginning of a start-up :

 

  • IRS alignment
  • Oxygen pressure
  • PSEU light
  • GPS light
  • Service Interphone
  • Engine panel (EEC )
  • Landing gear indicators
  • Mach & Stall warning
  • Reverser lights
  • Flight recorder

 

COMPOSITION

The components of the After overhead come from FlyEngravity and is composed of :

  • Frame;
  • ICS pcb with switches;
  • Annunciator holders with legends;
  • Subpanels;
  • Displays;
  • Buttons;
  • Coverbox for the frame;
  • Bezels and decals;
  • 5 Flat cables

ICS AFT Frame

This is the metal framework on which everything is mounted, such as the ICS-pcb with switches, annunciators, panels, gauges, displays, and decals. All the openings on this frame already. This frame is also equipped with the various DZUS-fasteners.

 

 

 

 

 

.

ICS Pcbs

These are the circuit boards on the back of the frame to be installed. The AFT-OVH consists of 5 pcb's that each individually further be connected with the FWD Overhead. This connection is done with a flat cable. The 5 flat cables each have a different width so follow the link impossible.

The ICS-pcb equipped with Smd-leds (annunciators), switches and displays such as LE Devices (Flaps/Slats) and the IRS Display.

 

 

 

 

 

 

Annunciator holders with legends

This 20 annunciator holders (housing of the annunciator or indicators) are composed of 4 parts : external holder, single holder, transparent self-adhesive plate in plexiglass and the picture with the inscription (legend).

SubPanels

These panels are no PEB panels (Easy Panel Backlighting) as in the FWD Overhead. The backlighting of these subpanels is done through Smd leds that are built-in on the ICS-pcb's.
The AFT OVH is equipped with 10 panels of each 4 mm thickness.

 

 

 

 

 

 

Displays

The 2 displays are different digital read-outmodules found on the AFT OVH.
One distinction the displays of the LE Devices (Flaps/Slats) and the IRS Display.

Both are already mounted on a ICS-pcb.

Gauges

The gauges are the different meterjes on the AFT OVH. For the AFT OVH is limited that only one gauge is that of the Oxygen pressure. For this moment, this opening is filled with a "decal" or sticker. In the future it will be replaced by a gauge from Flight Illusion.

Buttons

The ICS-AFT OVH is supplied with 2 Boeing Style knobs(IRS), and 3 special buttons for Dspl Sel, Sys Dspl and Audio V-B-R.

 

 

 

 

 

 

Coverbox

The coverbox is the ‘box’ in which the OVH-frame is mounted. The frame is so attached that this is for work inside at the front can detach and openkantelen to the bottom.
The coverbox is in turn attached to the metal suspension arm of the OVH-frame.

In both coverboxen of FWD and AFT OVH openings for cables to extend both parts.

 

 

 

 

 

 

 

Bezel and Decals

Any stickers that one here and there can make for quite the matter a bit more realistic.

*** Decal set for After Overhead ***

The bezel is a ring around the opening of the Oxygen pressure gauge.

Flat Cables

The AFT-OVH consists of 5 pcb's that each individually further be connected with the FWD Overhead. This connection is done with a flat cable. The 5 flat cables each have a different width so follow the link impossible.

ASSEMBLY AFT OVERHEAD

For me, there is in this After Overhead no assembly to come. Everything was already mounted on the frame by FlyEngravity.
Me rest with only the frame in the coverbox (idem FWD OVH) and the 5 ‘flat cabels to connect it to the AFT OVH and FWD OVH.

CONFIGURE AFT OVERHEAD

Further configuration of switches and indicators is not necessary since the AFT OVH is connected to the FWD OVH and so forms a part of the FWD OVH.
The ICS system and ProSim737 are matched by the voorprogrammatie in ProSim737 which all the functions are already working.
