    of them? I'm appreciating my cat more and more everyday. Each evening, my buddy waits for me to walk down to the hangar. He heels up and we walk down. If I let him in, he immediately dives into the insulated walls and starts the hunt. If I don't let him in, he works the hangar perimeter then takes a nap on top of the AC unit until I'm finished. Whether it's 30min or 4 hours, when I leave, he's waiting. He heels up, we walk home and he comes in for bite and a scritch. Haven't seen a dropping in the hangar since we started our routine... if I could just get him to bring the newspaper in the morning.

    of them? Ref the attached article. ".Hall says that without actually opening up the plane and looking inside there would have been no way of knowing the mice were there before takeoff." Hmmm, WRONG. Checking the carb heat during the run-up (as instructed by the POH) would have sucked the stuff into the carb BEFORE takeoff. FAA hazardous attitude anecdote: the rules are there for a reason. _____ As if bird's nests weren't bad enough, now we have . . . http://tinyurl.com/5vmasm Bob . . .

    Bob, If I understand correctly, as the landing-light-retract motor slows due to increased circuit resistance (and thus lower voltage at the motor), the motor current will not increase because the torque required to operate the retract mechanism is the same as before. The power (watts) of the motor is less because power equals speed times torque, and the speed has decreased. The total energy used to operate the mechanism will be about the same because it is a function of power and time. Even though the motor is less powerful operating at a lower voltage, it runs for a longer time and thus uses about the same total power as it would operating at a higher voltage for a shorter time. It seems to me that a slower motor develops less back-EMF and therefore would allow more current to flow. But on the other hand, higher resistance in the circuit counteracts that. I do not know how to calculate that, so I will take your word for it that the current stays the same. Suppose there are no high resistance connections and one compares the motor current at two different voltages, say 14 volts compared to 11 volts with a failed alternator. What happens to the motor current as the supply voltage drops? From what you wrote, I assume that the current will not increase. I am not trying to contradict anything that you said. I just want to understand. My experience has been with AC motors that try to maintain their synchronous speed by increasing current draw when heavily loaded or when operated at a lower voltage. DC motors do not have any certain speed that they strive for. Joe Gores

    I was going to test this but it soon became apparent that the problem was beyond mere testing. One consideration that I have not seen is that breakers wear out. "I squared T" or current squared X time" is how breakers blow, but the problem has many back alleys of complication. Once a beaker has tripped at above a specified current, the breaker will be degraded and trip thereafter usually at a lower current. All breakers have a one-time maximum trip current. (This is what is wrong with crowbar OVPs). So--can a landing light blow a circuit breaker below the specified lamp current if there are some high-resistance connections? My guess is "yes" but it depends on the breaker, the lamp, the nature of the loose connections, the wire, and myriad other variables. The likely culprit is the breaker.

    Paul McAllister was the first buyer of my LED position lights and tail lights, then after a horrendous run-in with some lightning, was also the second buyer. The tale of this episode in on Bob's AeroElectric Connection website http://tiny.cc/1utIH . The damage photos still frighten me! My third buyer landed in Texas USING only the LED position lights when his halogen landing lights had a circuit problem. This may have set an historic milestone in aviation lighting. But I have decided not to enter the field of LED landing lights, even though I am a big promoter of them. There is NO WAY for me to make money in the field because of the thousands of people busily engaged in developing solutions. Chinese companies are making exact drop-in replacements for any lamp you can think of, and many you can't.
