I'll add that the coastal route is longer, the fuel stops are further apart, and may be inaccessible IMC on days when the marine layer is persistent.

I've flown from Seattle to Marin every year for the past 15+ years. The quickest route is over I-5, something like BTG LATHE CHEEZ MOURN OED S03 (fuel stop) GRENA RDD RBL. The only part that requires climb rate & altitude is the section from S03 to RDD. After departing S03, you may need to fly a...

Normally and most of the time, true. Though there are unusual situations where it might be useful, like having to clear tall trees or other obstacles on final approach.

That's a feature, not a bug. Increasing drag enables you to descend faster without increasing speed accordingly. Of course, a slip does the same (increases drag). But as @Half Fast says, a slip doesn't also increase lift and reduce the stall speed, as flaps do. That's why the normal procedure is...

Note that "full flaps" in the C-172 models that are so placarded means 40* of flap. If you have only 30* of flap then it's not "full" and the advisory to avoid slips no longer applies. Consequently, one practical approach to this issue is to limit the 40* flaps to 30*. Then, you get +100 # to...

If you're too high, then the first steps should be to throttle back (if you're not already at idle) and deploy flaps (if they're not already deployed). After doing that, if you're still too high then you can slip to descend faster without increasing speed. In airplanes equipped with flaps the...

That sounds like a reasonable approach for the test. However, pragmatically speaking, when landing an airplane equipped with flaps, one would normally use flaps first, and slip only if flaps were not sufficient. That means when performing a forward slip to land, it would usually be with full...

My references say the opposite: ethanol has about 72% of the energy that gasoline does. Ethanol: 82,800 BTU / gallon. Gasoline: 114,500 BTU / gallon. https://en.wikipedia.org/wiki/Gasoline_gallon_equivalent Agreed here. Blending ethanol into gasoline does not provide net environmental benefits...

The POH certainly can prohibit certain actions or maneuvers, for example airplanes that are not certified for intentional spins are placarded "Intentional spins prohibited" - not "avoid" but "prohibit". As @dmspilot says, early versions of the 172 said slips with full flaps were prohibited...

I think my CFI handled this the right way back when I was training. He read the POH with me and explained the regulatory definitions of "avoid" and "prohibited", and why Cessna would use one term versus the other. Agreed. It's not "perfectly fine" (and I never said it was). But it is not...

It's not that, but a matter of the regulatory definition. Cessna knows the term "prohibit" has a specific regulatory meaning, and does not use it. It's not disregarding, but knowing what the words mean. If it should never be done, if it were an aircraft limitation, if it required the skills of...

Slipping in a 172, even with the placard saying "slips with full flaps should be avoided", is not ignoring the POH. Cessna could have said, "slips with full flaps prohibited". But they did not say that. That is the data that says it is acceptable. It's simple: "avoid" <> "prohibited" It means...

I did my checkride in a 172 with the O-360 engine and max 40* of flaps. Just before the last landing with the DPE, he pulled power when I was on downwind, said "you just lost your engine". I did a power off 180 slipping all the way through the downwind-base-final turn. Later I learned that the...

Hence your name - nice. Kudos for sharing, this can be a rough place but if you wear your thick skin you'll get good advice. Simple rule: always stick the tanks before every takeoff. Always = no exceptions. Even though you had a fuel cap leak, sticking the tanks can also catch a cap that is not...

That valve looks bad but small chance it might be salvagable? Mike Busch has a procedure to lap the valve in place. Then you fly the airplane for a few hours and check it again. That looks worth doing, maybe it can save that valve. If it doesn't and you must replace the jug, you haven't lost...

That's what I did in a similar situation a few years ago. No problem.

Good idea. Airflow provides even more effective cooling than rich mixtures. That should be no surprise, as these are air cooled engines. Climbing at Vy or slower, compared to level cruise, there is less air passing through the cowl and the angle at which it hits the cowl is not optimal. If...

A center pole table having a 3 legged base at the bottom of the pole would reduce or eliminate that problem.

Because of this I've always wondered why 3 legged tables are not standard.

I've seen this too. When I learned to fly back in 2007, I had 13 hours when I soloed, when I was ready it took 2 weeks to schedule a local DPE and I had 44 hours coming into my checkride. The hours sound low but it was not all that unusual for that time. Fast forward 17 years, now I am mentoring...
