B737 Cockpit Companion Pdf

[Ping Weafer]

Notsure I understand the logic behind the SOURCE OFF lights on the overhead Elec panel...From a dead ship, I start the APU. I then select, say, the APU Gen switch on the left to ON. The SOURCE OFF light on the left extinguishes, but the one on the right doesn't (even though the Right Transfer Bus has power). There is only one APU Generator and one Aux Power Breaker on the 737NG.Is there some obscure logic behind this? The 767 has a similar electical system, but the 767 panel layout/indications seem way more sensible.Thanks.Cheers.Ian.

Hi Ian,The SOURCE OFF light means that the (in your example) the right transfer bus is feed by the other source in this case the left transfer bus.This is what written in the 737ng cockpit companion:- no source has been manually selected to power the related transfer bus or - the manually selected source has been disconnected.- if a source has been selected to power the opposite transfer bus, both transfer buses are powered.- does not indicate that the AC transfer bus is de-energized example: in flight, left SOURCE OFF light comes on when GCB 1 trips, however, the bus transfer function lets IDG 2 power AC transfer bus 1.I hope this explane the function of the SOURCE OFF light.Best Regards,Alex

Ian, that's just because the 737 electrical system was designed by Fred Flintstone. The 737NG theoretical course was easily the most frustrating course I've done. Especially after the 757/767 course, this aircraft has a total absence of logic in its system design and operation. Actually, some systems actually employ logic that's 180 degrees opposite from the other Boeings, for example the speed trim system, which works to aid you during manual flight (make it easier to fly) in the 757/767/777, yet the 737NG speed trim works against you, adding extra opposite trim so it becomes harder to fly.. Go figure.

There are some interesting related comments on the SOURCE OFF light in this posting on the PPRuNe site (see link)... Not all the postings agree with what is being said here.... Perhaps someone should straighten them out ;-) =120071(I deregistered myself from the PPRuNe site so can't add my comments).Cheers.Ian.

Products from CMC Electronics CMCElectronics' integrated avionics suite, known as the Cockpit 4000, was ondisplay in the Alenia Aermacchi M- 311 jet trainer aircraft at this year's ParisAir Show.

The avionics suite is fitted in both front and rear cockpits of the M-311.The front cockpit consists of a CMC Electronics' SparrowHawk Head Up Display(HUD) and Up Front Control Panel (UFCP) and three 57 in. MultifunctionDisplays. The rear cockpit suite also comprises a UFCP and three 57 in.Multifunction Displays, one of which can also be used as the HUD repeater.

At the heart of CMC's Cockpit 4000 integrated avionics solution are two CMCElectronics' FV-4000 Mission Computers. The open architecture uses provenavionics hardware, which features Compact PCI/PMC technology. The SparrowHawkHUD and three Multifunction Displays in both the front and rear cockpits aredriven directly by the FV-4000 Mission Computers, providing control and displayfunctions for the high- resolution graphics of the navigation and mission data.

A variety of Multifunction Display pages can be displayed simply, using thesoft bezel keys. Selectable mission data include primary flight display, engineindicator data and stores management. Because of the centralized controlprovided by the two FV-4000 Mission Computers, all functions can be controlledfrom the Up Front Control Panels and/or Hands On Throttle And Stick, thusgreatly simplifying cockpit management.

The avionics suite includes simulated weapons delivery capabilities and canaccommodate other functions such as embedded Air Combat ManeuveringInstrumentation with virtual radar and Electronic Warfare simulation and digitalmapping.

CMC Electronics' new Portable Mission Display known as TacView was alsoexhibited for the first time. TacView is specifically designed to facilitatemilitary and paramilitary airborne mission effectiveness through improvedreal-time situational awareness. The system consists of a rugged, compact,self-contained, Night Vision Imaging System compatible smart display andcompanion power supply/interface module. TacView provides functionalityenhancement for military transports, fighters and helicopters without impactingthe aircraft's operational flight program.

Functions that can be hosted by TacView include tactical data link displayfor network-centric communications, portable mission planning, digital movingmap, weather imagery, electronic aeronautical charts and targeting pod imaging.In addition, the TacView provides Electronic Flight Bag (EFB) functionality forpaperless cockpit requirements for military aircraft.

TacView is large enough to display full-size instrument approach charts,checklists and moving maps, but small enough to mount in virtually any cockpit.Cockpit side mount, yoke mount and knee mount options provide the level offlexibility required for a wide range of aircraft. The TacView's super bright,sunlight readable 57 in. display features an integrated sliding keyboard,film-on- glass touch sensitive screen and bezel keys that provide an exceptionallevel of operator interface flexibility.

The design of the TacView portable mission display is based on CMC's industryleading PilotView EFB. The Austrian Air Force recently decided to equip theflight decks of three C-130 aircraft with a dual installation of the PilotViewEFB. PilotView is the sole OEM EFB option at Dassault, Gulfstream, Pilatus, SinoSwearingen and was recently selected by Embraerfor the E-170/190 program. Over23 STCs are available for the PilotView EFB on aircraft ranging from the GV tothe B737. The PilotView EFB is also installed on the Air National GuardC-32(B-757).
