![]() His original statement was there are only a dozen or so switches and buttons. No, I believe his original statement related to those buttons which are required for the pilot to manually control the aircraft and over ride the active route in the Flight Management Computer and those buttons are on the Mode Control Panel which is a portion of the panel above the 'glass cockpit' and below the window. The overhead panel and many other panels are NOT required during the majority of flight, they are for pre-flight and engine starts. The majority of the console between the pilot and his first officer are for radio, navigation radios, TCAS, transponders, weather tracking controls, autobrakes, passenger signs etc. I keep posting this typical approach and landing of a real 747-400. Whilst the FMC has the active route ATC require the pilot to retain certain headings, altutude and speeds which are ALL entered via these 'dozen or so switches', watch it and you will see. This isn't coming from my perspective or MXs but Boeings http://www.youtube.com/watch?v=5ShBOtPiuNM Ibby |

![]() Some of us appear to have a very abbreviated sense of what is "right" To posit that an airliner's Inertial Navigation System is "kinda like GPS" is akin to stating that the aileron controls work like a steering wheel! Neither approximation will get the ship safely to port. Yours is a dangerous and irresponsible contribution. The IRS system IS a system that provides positioning data of the aircraft to the Flight Management Computer but is not as accurate as modern GPS so my comments stand correctly. They perform the SAME function but GPS use is more common now. The 747-400 uses both an IRS and GPS data. NOTAMS will display which countries are GPS certified. The Pilot must configure the Flight Management Computer when flying over these countries so that the the IRS positions aren't updated with an innaccurate GPS position Ibby |

They perform the SAME function but GPS use is more common now. The IRS is more accurate over short distances and times, but the GPS is much more accurate over long distances and times, whence the utility of using both. The 747-400 uses both an IRS and GPS data. NOTAMS will display which countries are GPS certified. The Pilot must configure the Flight Management Computer when flying over these countries so that the the IRS positions aren't updated with an innaccurate GPS position GPS accuracy is not country-dependent, since it is a space-based system. I've never heard of GPS certification for countries; can you point me to a typical NOTAM for this? |

![]() I believe the original discussion was about someone with no clue finding the correct button to push to do a particular thing amongst ALL the buttons one would see. -- Jim Pennino Remove .spam.sux to reply.- Hide quoted text - - Show quoted text - Yes that is correct Jim but then it very quickly changed because of everyones attitude towards MX (rightly so at times) stating that his aquired 'familiarisation' of a certain aircraft through a simulator/ game would have NO bearing on what sat forefore you on the real flightdeck and this is where I stepped in to partially agreeing with MX's views (not his methods of response as others here just talk back in the same manner). I personally have FSX, a default installation is pretty **** for aircraft systems and flightdecks to put it bluntly. The default 747 bears virtually NO similarity to what is on a real 747 flightdeck with hardly anything modelled and most switches having NO effect. Good quality payware aircraft like PMDG 747-400X HAS a photorealistic 3D Cockpit which you can look around with the right pc hardware (TrackIR). Every button, every switch, every panel, every display on the glass cockpit IS the same as the real one. You can Google for real images till your heart is content or use the official Boeing sites or the likes of Airliners.net to compare sim to real. Most ppl on this forum just denounce it bears ZERO resemblence to the real flightdecks for which they model yet somehow the Trades Description Act has yet to be brought in and these Vendor's prosecuted for 'pretending' they bear a similarity.

![]() GPS accuracy is not country-dependent, since it is a space-based system. *I've never heard of GPS certification for countries; can you point me to a typical NOTAM for this? I am quoting from Angle of Attacks comprehensive video guide on the FMC's POS REF page. They state that the 'GPS NAV (ENABLE) button (Line Select 5 Right) toggles the GPS position (default is on) 'as some countries do not meet certain standards for GPS navigation', 'the GPS will then try to correct an accurate IRS position with an inaccurate GPS position, knowing what countries this happens in are part of the NOTAMS that a pilot would get in his pre-flight with dispatch'. I wasn't aware of this either so it would need looking into if you're curious |

I wasn't aware of this either so it would need looking into if you're curious I suspect Angle of Attack (which I have for the 767) has got something wrong or isn't stating something clearly. While it is possible to jam GPS locally, in the absence of jamming, the accuracy of GPS is the same just about everywhere, although it declines slightly near the poles (but not over any specific country). |
