Yesterday was a beautiful day for flying in the Philly area. We had a morning trip planned to 12N, Andover/Aeroflex yesterday morning, but the winds were cranking, especially the gusts. The steady winds were doable, but the gusts would have made for a less the pleasurable pleasure trip, so I decided to make it an evening trip instead, in the hopes the winds would die down, as they usually do in the evening. During the course of the day, I realized that it was only another 1/2 hr to Altoona, AOO, where Cathy's parents could meet us for an hour or so and have a quick picnic dinner if they so desired. A visit that would have been impossible by car, a 5 hr one way drive vs 1.25 hr flight. Cathy was excited, I was excited, and Sean was REALLY excited about getting to see Nana and Pap.

As hoped for, the winds had settled a good bit by 4 o'clock, the skies were still gorgeous, and we were set for a nice flight. Only possible negative was an airmet for occasional moderate turbulence below 8,000, and I wasn't convinced we'd have a lot of that, and even more convinced that the flight back would be really smooth. Sean has been handling turbulence with no problems in low wing planes, still had been showing some fear in the Skyhawk, bumps or no bumps, but with the prospect of seeing grandparents to distract him I figured even if we did get knocked around a bit it would be a good flight to help him get used to it and build his tolerance.

Got my first hint of possible trouble during the run-up. The ameter (which I know I'm misspelling, but can't figure out the correct way right now) needle was bouncing around quite a bit, which was unusual, but the indications were otherwise normal, so off we went. Once in the air, it turned out to be a wonderful day, just a few "wiggles," but no turb, winds aloft were low, and vis was fantastic. We were looking forward to a really nice flight and visit. Picked up my flight following, and notice the ameter was showing 5 amps... quite a bit lower than I'm used to. I got handed off to Reading Approach, and as I was levelling off, I check the ameter again. It showed zero, but the low voltage light next to it wasn't lit. Hmmmm.... tried to reset the alternator, but the needle still showed zero, but the light was still off, and I was hearing an unusual ticking sound through my headsets that sounded like it was coming from the engine. Either the guage was broke, the light was broke, or the alternator was broke. Given the weird sound coming from the engine I was kind of leaning toward a broke alternator, but I'm unapologetically chicken in the air anyway, so it didn't matter. Called Reading Approach and told them we were going back. She asked if I needed any other assistance, I told her no, if we lost the battery I'd be able to land fine without radios and flaps, and started my turn. At this point, I encounted an unexpected distraction in the form of a loud, plaintive wail from the back seat. Cathy thought Sean was scared because he'd heard the plane was broke and started to try to reassure him, but the cause of the sobs was somewhat harder to deal with... "I WANT TO SEE NANA AND PAP!!! IT'LL BE OK, LET'S GO!!!" Rats... I didn't have pilot isolate available, so Cathy got him shut up, but the boy wasn't happy. Back to the airport for a landing I'm quite happy with, and our little adventure was over. I was quite disappointed... Cathy had been really excited about getting to see her parents on the spur of the moment, and really pleased that all the sacrifices we've made to be able to fly were paying off in some small way. But such is life, and she knows there will be other flights. Still a bummer, though. It was somewhat harder convincing Sean, though.

On the making lemonade out of lemons side of things, as we were taxiing in Sean suddenly piped up from the back seat "Hey, I just realized I wasn't afraid at all, not even of looking down!!" And proceeded to regail us of how cool looking down and seeing jet skiers on the river was and, most impressive to him, looking down and watching a horse eat while we were on final. This is a BIG step. The poor guy has been terrified in the past in the Skyhawk, especially when he'd look down. We tried to tell him not to look down, but I guess that's like saying don't look at that car wreck. I guess as he's gotten to fly a bit more, and I've gotten smoother on the controls (which I've been working hard on, slower control movements, shallower banks) he's been getting used to actually flying. It's a big deal to us, and him. Most cool. Plus, we DID get to go flying, and it was a really nice flight while were up, so I guess sometimes we just have to take what we've got :)

Lessons learned: I figured we had plenty of battery power to make it back, and was prepared to land without radios and flaps if I didn't, neither of which is an emergency. But I do have a fairly recent acquired handheld radio in the flight back... and didn't even think of it. Wonder why not? Also, an extremely sad, disappointed, and upset six year old really is more of a distraction than I'd thought he would be.

Joe sounds like it could have been a lot worse when all is said and done!

Glad everything was ok. Do you have and idea what was the problem?
 
Joe,

I just had a similar experience on my Mooney coming home from San Jose on Friday. Ammeter went to "0". I did not hear any noises. I also tried to reset the alternator, to no effect. I pushed on and landed at KPRB. I had no idea if it was the alternator, regulator, etc. but was lucky enough that it was a broken wire off the alternator and I was back in business.

No, no idea. Abe, the lineman/jack of all trades who runs the place, is off on Mondays. I'll call him tomorrow and chat with him, and he can get with the mech.
 
Wow Joe. You probably made the right call, I'd be upset to have to pay for the time in that case. How do FBOs work that out?
 
What did the voltmeter read?

I had the "broken alternator" issue, and it was just a ground wiire that was disconnected.
 
Electrical problems s*ck. However as Joe noted, in day VMC they don't have to be an emergency. Night or IMC, they are potentially very dangerous. Its good to have a Voltmeter in addition to the Ammeter, especially the kind that will flash at you if the voltage goes below a set peramater. This way you can see the problem before it becomes and emergency. You may not catch the Ammeter showing a discharge right away until you start seeing problems with the radios, etc. Then it is too late.

Good call Joe.

The problem has been unearthed. The pilot was an idiot :(

Basically, I read the guage wrong. The ammeters I'm used to have a zero in the middle, and the needle will read to the right or left of it to indicate a charge or discharge status. I thought all the guages with the zero to the left, like in this plane, were load meters. I've always thought this plane had a load meter, and when I check it during runup it's always showing what looks like between 10 and 15 amps. Of course that's just after engine start, and I now realize that I've not been including it in my scan of the engine instruments in flight. The only reason I was looking at it this flight was because the needle was bouncy during run up, so I was keeping an eye on it... watching as it slowly settled back as the battery was charged. Apparently, the low voltage light is there to indicate a discharge condition, which this guage cannot show.

I thought of hiding my shame, but perhaps there's a lesson in here for someone else. On the plus side, I suppose, I still haven't had an actual inflight failure on the planes I've flown... that's actually speaks pretty well for the planes, I think, considering how old some of them are, and the way rentals get treated in general.

:redface: I'm so embarrassed!! :redface:
 
I appreciate your willingness to share your experience with us at the risk of being laughed at. I really do believe someone will benefit from your story. You should pat yourself on the back for sizing up the situation and making the right decision to head back, rather than pressing-on into what might have become a bigger issue. Even though this particular situation would not have become a problem, it did teach you to deal with unexpected in-flight annomalies. That will be helpful if and when an actual problem arrises. Hopefully you've gained some confidence from the experience.

I've had an alternator belt break in-flight. I didn't know it at the time and as the battery drained, we began to lose certain items on the panel. Lights were dimming and such. Then on the approach to our home field, the BRIGHT red light located above the ammeter illuminated. That was when I first noticed that we'd be losing the electrical system. It was a lesson learned for me. I had not been including the ammeter in my scan. I'd been flying for a long time and been training for the instrument for a while, still, I had not for whatever reason thought to scan the ammeter regularly. Luckily, everything turned out ok, but barely. It was night and we were IMC. The MDA on this NDB approach was 1180. Sky was overcast 1200. Let's just say I didn't want to go missed. The alternate was Portland, so I knew we could get in there, but probably NORDO.
 
I need to get a BNC cable installed in the Tiger so I can actually transmit with my handheld. Should have had this done at annual when my plane was apart and the avionics shop was also playing with it.
