GPS instead of turn and bank
"Danny Deger" wrote in message
... I am thinking about buying a 1946 Taylorcraft that has NO gyros at all on the panel. I really want at least a turn and bank so I want die if I loose reference to the horizon for any reason. I have been told that the heading information from a GPS is good enough to do the function of a turn and bank and allow emergency operations without having a visual horizon reference. Is this correct? Some time ago (a few months?) someone (an insructor - don't remember who) posted a note either here or R.A.Student about giving a flight review and covering up ALL the gyro's and the student kept flying on track without falling off into a turn as expected. After a period of time, the instuctor inquired as to how this was possible (thinking the student was "peeking" under the hood) and was informed that he/she was using the track indication from the GPS to keep it straight. So, apparently, it can work. I tried to find the post - no joy. You are on your own if you want to dig up the details. -- Geoff The Sea Hawk at Wow Way d0t Com remove spaces and make the obvious substitutions to reply by mail When immigration is outlawed, only outlaws will immigrate. |

Please note that there may be a discrepancy if you are not coordinated, this is also true of the regular six-pack. If you cannot be sure that you are coordinated, you cannot hope to calculate the bank angle. I've never had the freaking ball fail on me yet. Most aircraft in cruise regime have no problem being coordinated without pilot input...they're specifically optimized for that. |

It cannot be done. But there are many still trying. http://www.approach-systems.com/apic.asp Bob Moore |
