Ah! Not the right ones for your degree of frequency overlap...

Have you tried the color blindness correction glasses? My nephew found them quite revealing, and he works with colors also. Paul

There's no requirement for a report to the FAA even if you make a gear-up landing that leaves the airplane unflyable. The NTSB reporting requirements also exclude a "simple" gear-up landing. At a towered airport, the tower will log it as an event, and it may make its way to the FSDO that way...

Mine is turbonormalized, Dan... and switching to one mag effectively retards the timing, and cools the engine... even at full throttle. Paul

Sure, I do that every flight, as part of my LOP cruise mag check... much more demanding of the ignition system than the pre-takeoff checks. On one mag, the EGTs go up, and if you wait a minute, the CHTs come down. Paul

When I geared-up my Cardinal, insurance asked for one hour ground and one hour flight instruction, with focus on pre-landing checks. The FSDO agreed that was adequate retraining. Paul

That depends! If you have a gravity-friendly path to a drain, great. If not… pump. Paul

It's quite the opposite. Look at what happens when you do an inflight mag check... the combustion slows, as evidenced by the higher EGT... and power output declines, as evidenced by the lower CHT and lower airspeed. Lower CHT equals LESS chance for detonation. Since the combustion takes longer...

Forced air furnace? Then you may well be able to use the existing ducts. Wall furnace? Not so much... Now available are cassettes that mount in the ceiling, between joists. When turned off, it's a flush panel, that you can paint to match the ceiling. When on, the duct doors open to bring in...

That's not necessarily accurate. In California, to be self-insured for automotive liability, you merely have to convince a bond and surety company that you have sufficient assets to satisfy the required claim amount. There's no dedication of assets or set aside required... just a demonstration...

I suspect the sarcasm was the math... "for every 1,000 feet increase in altitude, the sun's intensity increases almost 10 percent" So there's 200% more sun at 20,000 feet? Doesn't seem that much brighter... Paul

LP Aeroplastics offers an upgrade to plastic that blocks UVA, UVB and IR. I have them. Paul

Yes it does. Used to be a few without the exclusion... but no longer AFAIK. Paul

Just drove an Avis Pacifica from California to Missouri. We both enjoyed it… the dogs loved the disappearing middle row of seats… big flat lounging/play area. Considering the PHEV… Paul

Maybe it’s telling us that engine failures don’t necessarily result in accidents. I’ve had half a dozen engine failures in 45 years of flying… no accidents yet! That said, I’m very cautious during the first 30-50 hours of engine operation… two oil change intervals (first change at ten hours…)...

As others have stated, even an engine with a 0/80 leakdown test (compression test) can make full power. It's just that there will be lots of blowby and other undesirable side effects. And you may be headed for a failure if the leakage is past the exhaust valve due to thermal distress. The...

We recently drove a rental ICE Pacifica California to Missouri to help the nephew relocate. At a number of gas, pee, or coffee stops, we were proximal to rechargers, and I’d stretch my legs and survey the customers. A couple non-Tesla folks, one Volvo, one Mustang, were very disappointed in...

Pump and pressure tank at bottom of hill… need 1# pressure per 2’ rise, roughly.

It speaks Capstone, so the Apollo legacy boxes, like my GNS480, support that. Have requested that Avidyne support Capstone XPDR control going forward. Paul

Two errors there. First, all hydrocarbons, from methane (natural gas) through roofing tar have about the same energy content per *pound* but, since density varies, BTU content per cubic foot or gallon varies widely. second, flame temperature does not correlate well to density … it’s a function...
