I like my old whisky compass. Its max deviation as installed in flight with engine running, radios on, etc. is never more than 1-2...

All of the guys I know that blew an engine had excellent oil analysis prior to throwing a piston:oops: .

Not in my case. I took every sample from an engine still warm immediately after flying, mid-drain (not near the start nor end), directly...

One problem is that oil analysis can give both false positives, and false negatives. It can show high metals when there is nothing...

Over decades, congress has ceded too much authority to the executive branch leading to an imperial presidency. Hence the flagrant abuse...

But if you're 5000' above the airport, that's already an uncommon position to be in. What do you do to get to the point where you can...

You mean if you need to get upwind, so fly a little faster? Sure.

5000' above gives you a lot of margin. While trimmed for best glide, I will circle over the approach end of field, on each leg of the...

This is the reason one of my instructors felt it important to teach power-off 180's to primary students, despite it being a "commercial"...

Can you be more specific? Some cars store the H in liquid form and convert to gaseous on demand for combustion.

Chances are, if you ride motorbikes or fly airplanes, and do it long enough, you know people who have been killed doing this activity...

No. A V8 has 2x as many cylinders but likely not 2x the number of parts, so cylinders and any parts duplicated per cylinder will have...

The problem with H is low energy density, and addressing that means liquid form which means being very cold, which means mechanical...

Yep. She taught that "he" was considered to be gender neutral unless the context of usage made gender clear. Due to English lacking a...

Agreed, that is my point. Sure, two engines doubling the risk of failure is just a rough rule of thumb. Yet the fact remains, the...
