    Please help - Do I have to disclose a sealed record?

    I think the recommendation was to ask Bruce for a referral to a good lawyer with knowledge about aviation medical issues. Given that he's one of the most knowledgeable AMEs in the country, I think this is an appropriate query.

    Co-Ownership %

    No matter what the arrangement is for co-ownership, a well defined exit strategy is a must!

    Another crash :(

    I never liked PUSH nor do I like "forward pressure" for the stall recovery description. To me the only thing that makes sense is "Unload the wing" and the best way to describe that is move the elevator until you feel lighter in your seat (or for you crazy/wise folks with AoA until the AoA...

    panel upgrade vs tablet

    I wouldn't consider an iPad as a MFD replacement for serious IFR flight but for VFR and "light IFR" it should do the job. The main downsides (assuming you mount the iPad somehow) are the lack of sunlight readability, overheating concerns, lightning connectors falling out in turbulence, and the...

    Aircraft tax depreciation with CFI spouse

    Not the case for me. I have a house in Michigan that I rent out except for a couple weeks for personal use (my wife likes it there). The income from the rental is offset by the expenses for the house including depreciation (which is basically just a zero interest loan from the government) but...

    Tach time vs Hobbs time

    That ratio depends on the airplane (especially fixed vs C/S prop) and the type of flight. 1.3 is about right for a 172 doing touch and go landings and some other 1 hr training flights but the same airplane running high power on a long trip will actually get more time on the tach than the Hobbs...

    Full Fwd/Aft Trim

    I would certainly expect this effect to be somewhat proportional to the size of the trim tab relative to the elevator and IME it's not a huge effect on most airplanes. It also seems contrary to safety to use full nose down trim in the landing flare given that this means you have to pull really...

    Thinking about moving to the midwest late this year

    Probably don't have a lot of hot muggy days either.

    Full Fwd/Aft Trim

    While this is true, elevator trim implemented with tabs does affect control "effectiveness" but in the opposite direction one might expect. IOW if you apply full nose UP trim the elevator will become more effective with the wheel fully forward (nose down) and less effective with the wheel/stick...

    $4 million in damage...

    My nephew works there and is probably involved with this airplane. I'll have to ask him what actually happened. He runs a crew that completes new business jets but I think he told me he was going to be part of the team upgrading VC-25.

    Thinking about moving to the midwest late this year

    A tiny bit farther west than Wisconsin you'll find the "Little Apple" (Minneapolis). We have a large network of GA airports (seven with paved runways, 4 with control towers, all with approaches). We're also very high on the "Best places to live list. I live 25 minutes from Downtown Mpls (35...

    What causes stalls?

    One often overlooked effect of high DA in the pattern is that the resulting higher TAS requires a wider pattern or greater bank in the turns. The usual result is more overshooting the turn to final.

    Stop training to wait for medical?

    While you're waiting for your SI, see if you can hook up with one or more pilots you trust that make $200 hamburger runs or trips to places you'd like to visit. Split the flying and the total cost if it's a rental or just the gas if the pilot owns the plane. Mix this with some dual every few...

    Aircraft lithium battery fires

    Li-Ion batteries require very well controlled charging and discharging. Typically in any expensive gear that's controlled by a dedicated microprocessor that measures the current going in and out, the battery or individual cell voltage(s), and temperature of the pack. With that kind of setup...

    ADS-B Weather as Substitute for AWOS/ASOS ?

    That's what windsocks are for. ;) I had something similar happen once. I flew from home base where the wind was out of the east at something like 10 Kt to an airport about 20 miles west that had no wx reporting. I entered the westbound downwind and after turning base and final towards the...

    mx cost shootout: Comanche vs. Bonanza

    The "common knowledge" is that Bonanza parts are more expensive but don't need replacement as often so the long term costs are probably pretty close unless you're extra hard on airplanes or just unlucky. And while Beech's prices for some parts will take your breath away, most of the things that...

    Insight G4 vs JPI 900

    How would you monitor oil pressure if the only gauge is unpowered until you turn on the avionics master?

    What causes stalls?

    Taking a crack at the original question: In mathmatical terms lift, dynamic pressure (indicated airspeed) and AoA are inseparately related as long as the AoA is in the range from the zero lift angle to a little less than the critical angle of attack. IOW if two are fixed you cannot change the...

    What causes stalls?

    Your reply suggests you're confusing AoA with pitch attitude. If you're AoA is less than the critical angle and you reduce lift without changing airspeed you have just reduced the AoA. If you reduce thrust and maintain the exact same AoA there will be on stall. How could there be a stall if...
