Can EFIS / EFMS lead to removing basic safety checks?
Jim Carter wrote:
This question is the result of the wrong runway issue at LEX last weekend… Not having flown an EFIS or EFMS myself, I'm not sure of the "into position checklist items". For example, in a standard steam-gauge panel one of the last things we check is to align the directional gyro with the runway heading and compass. With an EFIS or EFMS, is there any such last minute check, or is the heading assumed to be correct because it was aligned by the GPS when the bird came out of the chocks? If there is no requirement to manually align and verify runway heading, compass, and EFIS/EFMS then our technological advances have inadvertently removed one of our heretofore unrecognized safety checks. I heard some retired commuter pilot on the news last weekend suggesting that the only way to prevent this in the future is to put traffic lights (stop / go) on the end of every runway. I absolutely got the impression that he was there to convince the public that it is almost impossible for the pilots to get it right and the lack of the traffic signal was the whole cause of the problem. Sort of the typical "not my fault" attitude. In the modern jets and many GA airplanes too the DG automaticly aligns the correct magnetic heading. Checking the EFIS heading prior to take off was not on our companies checklist. Michelle P |

Can EFIS / EFMS lead to removing basic safety checks?

My question was more along the lines of new systems removing old safety checks, but no one seems to be addressing that. Is there any physical action that must be taken as an aircraft with and EFIS / EFMS moves into position for takeoff to assure that the compass / gyro (or suitable substitute) / display all agree on the runway heading? Could the modern glass cockpits be setting us up for incidents or accidents because insidious little actions we used to take with analog panels aren't necessary any more? Probably the best tool is a highly-detailed moving map presentation of the airport diagram. Having said that, the pilot still has to know the difference between "22" and "26." |

It should not have to be on any company's checklist. Some things are basic airmanship. No, they're equipment-specific procedures. Doing a mag check prior to takeoff is not "basic airmanship" either, nor is realigning the DG every 15 minutes. They're specific procedures required by specific equipment, and neither is relevant on a modern turbine-powered airplane. Did you align the IRUs in your 152 before you started moving? Check the landing gear doors as part of your walk-around? Of course not, because they're not appropriate procedures for THAT AIRPLANE. See what I'm getting at? |

Why would the EFIS be any different than an HSI (or as Bob already posted the 707 RMI). It still has a heading which ought to be verified with some real reference (Whiskey compass or runway). Of course it's easy to get complacent. Back when I had a regular DG that had to be set, I cross checked it against the compass/runway on takeoff as a matter of course (since it was almost assuredly wrong). Now that I have a slaved HSI, it's almost always right so I could see forgetting to check it. Of course, I also have GPS plotting my position on the Jepp airport diagram page if the field has an instrument approach so I probably was one up on these Conair guys. |

Of course not, because they're not appropriate procedures for THAT AIRPLANE. See what I'm getting at? I see what you saying about specific procedures for particular aircraft, but shouldn't heading cross-checks be basic airmanship? In the analog aircraft that entails manually setting the DG when cross-checking with the runway and compass. Having not flown and EFIS / EFMS equipped aircraft, my question was is there a similar cross-check or has the system negated that necessity. It seems from the answers that the heading cross-check is no longer manual or an actual checklist item, so the system has eliminated that safety check. Now the question becomes, would a checklist item have caught the complacency if that is truly what the root cause of the LEX accident turns out to be? |

I saw this demoed somewhere (but I don't remember where). It was pretty cool. There was a row of read lights across the taxiway access to the runway until cleared for takeoff. This is used some places. After a spate of Runway Incursion accidents (well like five years later, even the FAA's knee jerk reflexes are slow) the FAA did all sorts of things from pilot education, ATC procedure changes, charting, signage, ground radar, and lights to try to diminish runway incursions. It's amazing to me that sort of stuff SHOULD have applied equally to the "WRONG RUNWAY" (how to you avoid incursions if you don't know which runway you are turning onto?). Didn't seem to have worked. |

You would only check the EFIS heading if the Comparator smelled trouble and triggered a warning. The computer cross checks the left and right systems so the pilots do not have to. Michelle P |

Placing the runway heading on a steam gauge HSI was considered good form at my company, but certainly not a checklist item. |
