I guessed what happened the moment I read that you had flown through the localizer. This is becoming a real problem and I am beginning to think that there is a fundamental design flaw in advanced avionics systems. I have noticed a tendency for people to forget to switch on the CDI even when they are very familiar with the GPS. This is one reason we like our setup, which is a separate CDI dedicated to the GPS. It's always GPS, the CDIs are always LOC/VOR. One question for the original poster: is the GPS moving map in your scan? Does it automatically, or is it configurable, to show the loc course? I do this, and find it helpful. If the CDI must be manually switched, it definately needs to be built into one's approach checklist and as the original poster pointed out, that's the reason it's needful to become familiar with each installed avionics setup. If I moved into a plane (or a setup) that required manual switching I'm sure it would bite me before I'd had time to integrate the check into my procedures. Cheers, Sydney |

I have watched folks under the hood screw the pooch (figuratively) by
not being familiar with equipment and avionics. I have to wonder.. how did you blow through your required fuel reserves for IFR with only "one" missed/messed up approach? Were you stretching it, not plan for winds or were your fuel numbers wrong some other way? Glad you lived to talk about it.

As a lurker here for many years, I have come to enjoy reading about people's experiences and try to learn from their mistakes. So tonight I am posting my experience in hopes that someone else can learn from me. Today started out as just any ordinary day with a cross county flight that was going to take about 4 hours there, drop someone off and then come back home. I was in a Seneca II turbo and the weather was looking mostly VFR with the occasional MVFR called for my route, but was clearing. My flight to my destination was uneventful. It was the return flight and about 9 minutes out from my final destination when things went wrong. It was around 2200 and I was on with center with flight following and I turned to the ATIS to get weather for my destination. They were advising of Snow and ceilings at 2500. But how could that be, this stuff was not forcasted, I'm about 30miles out, flying at around 4500 agl and I have the city in site, but not the airport. I asked center if my destination was IFR and they advised that they were not. The center then handed me off to approach. I proceed to descend in anticipation of lower clouds then BAM, the city went away. I was not IMC at the moment but I could not see anything in front of me. I thought to myself, no big deal, I will call for local IFR and shoot the ILS in. I have shot this approach many times.... Well at least in an aircraft with 2 nav radios and a GS. I have about 50ish hours in this Seneca (mostly x-county time) and we had just gotten the MX20 and CNX80 system put in about 3 weeks ago. I really haven't gotten use to shooting approaches with this system yet but here we go. Approach gave me vectors and altitude changes. Now I'm in IMC. There's a little vertigo coming into play now (don't know what that was all about) so on came the autopilot and let my head clear. Now I'm flying straight and level and on course. I knew I had about 15 or so miles to go before they would start turning me in to the ILS so now I'm pulling up the approach plate on the mx20. I have the paper one in my lap but I was going to use every tool to my advantage. It pulled up, now I can see exactly where I am on the approach. Now for the final vectors, I've got the ILS tuned into the nav portion on the CNX80, I'm getting what appears to be the proper reading on the HSI. But the ILS needle isn't moving. Next I hear from approach that I have blown thru the localizer and that they were going to turn me back around for resequencing. No big deal. I looked at my configuration on my systems to try and figure out why I never got the localizer. The frequency was correct, I confirmed it with approach and they advised it was working correctly. Then I saw that I did not push the CDI button. I hit it and it came alive. Now just as they are turning me back for final vectors, I look down and see that my right fuel gauge is showing 0 but my left is still around 20. I then intercepted the localizer and turned inbound. It was at that time the right engine dies. I reached down and hit the cross feed but nothing. Now here I am, in IMC, flying a plane with avionics that I have very little experience with, with my best friend (which this is the first time he has ever flown with me) and now with one engine dead. With all of this, you can say I got a little distracted and started getting off course. I had already switched to tower freq by now, so I declared priority due to fuel. The left was still showing almost 20 but we all know how fuel gauges are accurate. An American Airlines had just landed in front of me and he advised that he broke out at around 1500 agl and that it was +10 vis underneath. I was able to get back on the ILS and intercept the GS. I then started my decent leaving my gear and flaps up (I had plenty of power on one engine to maintain blue line, but did not want to take a chance) Just as I was about to secure the right engine, it started rumbling to life. I don't know if it was the descent that shifted the fuel or fuel was finally making it thru the cross feed, I was about 1500 agl and broke thru the clouds. There was the runway. The most beautiful site I have ever seen. Flaps came out; Gear came down, and I landed. I was drenched with sweat and it was 12 degrees and snowing but I didn't care. I opened my little window and let that cold air in... It felt good. I was alive. Now it has been about 3 hours since I landed and I can not sleep a wink. I keep thinking to myself how foolish I was believing that I could go IMC using equipment that I was not all that familiar with. Another thing that I can kick myself in the butt for was to not paying more attention to my fuel situation. There are low fuel lights on the annunciator panel but they never came on. The bulbs work fine, I did test them. But without the proper training, I might have allowed all these things to just come to a boil. There were some moments of panic ( especially when that right fan quit) but I was able to use the basic training of dealing with engine outs and flying on a single engine that I was able to regain my composer and continue to fly the ILS on one engine. Without having that, they would probably be looking for the wreckage now. Thanks for reading my long winded story but this was kind of therapy for me. I think that I can now go and get some sleep.

I have to wonder.. how did you blow through your required fuel reserves for IFR with only "one" missed/messed up approach? Were you stretching it, not plan for winds or were your fuel numbers wrong some other way? I think he filed VFR and was surprised, after 3+ hours of flight, to encounter IFR conditions. He requested a clearance to land... or am I reading the wrong post? How many of us of asked for and gotten a clearance to descend through a layer with little or no thought to required IFR reserves? |

It was my impression that the pilot simply forgot to switch tanks, and
flew one tank dry while he had 20 gallons in the other tank. However, what is the fuel burn rate in a Seneca II? Is 20 gallons worth 45mins? Dave S wrote in message link.net...

However, | what is the fuel burn rate in a Seneca II? Is 20 gallons worth 45mins? | It is a little more complex than that. Normally the Seneca burns fuel for the left engine from the left tank and fuel from the right engine from the right tank. It is possible to run out of fuel for one engine and not the other. I don't remember which tank the aircraft heater draws fuel from, but I think it is the left. There is a crossfeed valve that allows you to run both engines from either tank. The engine failure checklist calls for turning on this crossfeed valve, which he apparently did. However, the OP could have opted to simply feather the stopped fan rather than attempt to restart the engine while flying a tricky ILS approach where he was already behind the airplane. The Seneca is easy to fly on one engine and continuing the approach on one engine may well have well have been the better part of valor. He would not have had the option of going around or making a missed approach if anything went wrong, though, so he probably did the right thing by restarting the engine. The Seneca II burns between nine and twelve gallons per hour per engine in normal use. The turboed version burns a little more. Nursing it a little bit, he may have had over an hour of fuel left, especially since he was descending anyway and had elected to keep his configuration clean. Other things I think the pilot did right include turning on the autopilot when he started getting a little vertigo, leaving gear and flaps up on the descent (approaches in the Seneca usually are flown with one notch of flaps and gear down), and declaring that he was low on fuel. |

Well, tonight will go in my book as something that I will never forget. Tonight I learned a valuable lesson and was able to live to tell about it. As a lurker here for many years, I have come to enjoy reading about people's experiences and try to learn from their mistakes. So tonight I am posting my experience in hopes that someone else can learn from me. Thanks, a good reminder that even though the plane is IFR equipped, the pilot may not be ready to use those instruments. I guess there's something to be said for the simplistic KX-155 ![]() snip I looked at my configuration on my systems to try and figure out why I never got the localizer. The frequency was correct, I confirmed it with approach and they advised it was working correctly. Then I saw that I did not push the CDI button. I hit it and it came alive. Now just as they are turning me back for final vectors, I look down and see that my right fuel gauge is showing 0 but my left is still around 20. Congrats on a safe landing when things weren't going well. Did you find out why the left tank had 20Gal, but the right tank was empty? I would assume they were originally filled to the same level and that the engines were feeding from their respective tanks per standard Seneca II ops (ie not crossfeeding). I am curious - do you have the 93 or 123 gallon tanks? -Nathan |

Thanks, a good reminder that even though the plane is IFR equipped, the pilot may not be ready to use those instruments. I guess there's something to be said for the simplistic KX-155 ![]() Is there a broader question of whether any pilot is fully capable of operating (GPS) equipment in any a/c other than the ones they have trained in? My experience is VERY limited. With little exception, I've trained and flown IFR only in my owner operated a/c. It was very clear to me that the button pushing idiosynchroncies of my particular unit (G 300XL) were specific to not only that unit, but specific to the installation in my a/c. I would feel confident of being able to operate another 300XL installation but would be aware that installation options could change certain procedure significantly. The 400/500 series Garmins are pretty common and I assume that most pilots fully trained on one would feel confident operating other 400/500 installations. But I know from the couple of training flights I did with a 430, I never caught up with it. Ironically, while GPS has made accurate navigation bone simple, it seems to make jumping from plane to plane more challenging. The moving map practically eliminates loss of spatial awareness, but the button pushing required can lead to brain freeze trying to figure out how to make it show you what you want. |

I guess there's something to be said for the simplistic KX-155 ![]() It's not really simple vs. complex. When I joined the club, I was switching from KLN-90 something-or-other to a Garmin. I find both to be quite simple...but at the time, I'd never used a Garmin. So I know I'd not fly IFR in a club plane until I'd read, watched the video, and played a bit. It just seems to be common sense. - Andrew |

I reached down and hit the cross feed but nothing. Another scary thought ... With the aircraft flying unbalanced (ie banked 5 deg towards working donkey, and compensating rudder applied), I doubt very much if anything close to the full 20 gallons would be available. Curious also as to why such an (apparant) imbalance between the tanks? |
