My experience with OH gyros has been so-so... Not horrible, but not good
enough to risk my life on them... One time back in the 60's, flying my Skylane up to Drummond Island to take my boys fishing, I did have my only horizon slowly wind down and roll over - I used the TC to let down underneath and fly marginal vfr back to my home airport... It was an old unit that had been overhauled a couple of times in a 7000 hour airframe... My rule since then is that the PIC AI/TC have to be replaced with new if they go sour... Back up gyros/nav-heads can certainly be OH units... Most of us have two VOR, so I don't have strong feelings on them... But, many pilots have just one GS, so it needs to be trustworthy... I have actually had the fun experience about two years ago of having an recently overhauled GS head pack it up in, 300 and a mile conditions ... The needle centered on the bubble and stayed there... No warning flag... If it weren't for the fact that it was rough air and I had been having to jockey the throttle all the way down to that point I might have been lulled into a bad situation... I got suspicious fairly quickly, added power, and when the needle did not react and declared the missed approach... That was the day I added another rule to my book - the copilot side ILS radio WILL be turned on and on frequency during any real IMC approach... Yup, seems some of those on here are spoiling for some kinda fight... Wrong guy for that... I'll just keep commenting where I see fit... denny "Jay Masino" wrote in Dennis, I tend to agree with you. My experience, as well as the experience of my avionics person (who's also a friend of mine) is that the overhauls don't tend to last as long as new. I'm not sure why you're statement is causing so much heartburn. |

I don't know about actually paying more to put one in, but in my Cherokee,
it's slightly nice to have. I usually leave it set to IAS (non-corrected), but once in awhile when I'm bored at 9000', I'll check to see how much headwind I'm fighting between the TAS and GPS readouts.... I've got good eyes, and for some reason, it *is* a bit awkward to set the temp/p-alt in a TAS indicator. Just a weird combination of numbers, I guess. -Cory In rec.aviation.owning Jay Honeck wrote: : I've always had a TAS ASI, and I've never had a problem setting it : correctly.

After you've done that once or twice, you will know what your airspeed will normally be at 9000 feet. From that point on, a glance at your GPS ground speed will tell you precisely what kind of headwind you're up against. I'm not saying it's not a useful doo-dad to have on board, but I sure wouldn't pay extra for it. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

Before you get too excited, check with your local FSDO. With the Teterboro FSDO, the instrument must either be the exact make and model of one on the original equipment list, or it must be STC'd for the aircraft. It may be possible to get others approved, but it's like pulling teeth on a Grizzly with no anesthetic. George Patterson Treason is ne'er successful, Sir; what then be the reason? Why, if treason be successful, Sir, then none dare call it treason. |

Not right now you wouldn't. The whole workshop is in boxes in the barn waiting for the rebuild of the hangar benches and furniture. Jim "Jay Honeck" shared these priceless pearls of wisdom: - -Am I the only one here who would pay good, hard-earned cash just to see -Jim's workshop? - -:-) Jim Weir (A&P/IA, CFI, & other good alphabet soup) VP Eng RST Pres.

I haven't had one apart in twenty years, but as I recall, the shaft for the TAS knob was outside the pressure vessel. Jim rip shared these priceless pearls of wisdom: -And, when you get your pitot/static check done, the shaft for the TAS -knob is pretty much a guaranteed leak.

Well I got my ASI today looks great bright lettering pito/static system will
be rechecked on Friday to see if it holds when the avionics guys return from Vegas on Friday look great in my panel. "G.R. Patterson III" wrote in message ...
