Re: Landing at night before the lighted displaced threshold

It's in AIM AGA 3.5 (not 3.1):

"When the portion of the runway preceding the threshold is
marked with arrows (see AGA 5.4.1), it is permissible to use that
portion of the runway for taxiing, takeoff, and landing roll-out
from the opposite direction. "

Re: 172 flap detents at 15/25 instead of 10/20

They are single slotted flowler flaps on the Cessna 172. For the first 10 degrees of flap the travel is more extension than deflection. To 20/30 degrees they now move more in deflection than extension. To measure the flap deflection in degrees you set an inclinometer to 0 on the bottom of the flap ...

Re: 172 flap detents at 15/25 instead of 10/20

Your flap lever and cutouts are correct! The top of the flap lever indicates the flap selection/travel, so to get 10 degrees you select the flap lever to the bottom of the first cutout. The top of the lever will indicate 10 degrees flap and that should correspond with the actual flap angle. Same fo...

Re: FedEx quietly begin single-pilot tests - ATR 42

Also, redundancy is one of the many important roles the PM brings to the cockpit. I don't know how you could work in the airlines and not know this.

Flight engineers used to be just that...engineers. They monitored and ran the complicated and decidedly unmonitored and non-automatic systems available at the time. They did not ever need to be pilots. Do you fly large transport airpłanes ayseven? I ask only because if you do your flight operations...

Re: Fuel density effect on range/fuel capacity US West coast against south east Asia

The point he is making is that aircraft fuel tanks are limited by volume, so the weight of that fuel that you can carry will depend on the fuel density, and that depends on temperature.

Re: O-200 cold weather starting

POH says "with ignition switch off and throttle closed, prime the engine four to ten strokes as the propeller is being turned over by hand". Presumably that means forward.

Re: Carb fire season

Here is the exact quote (from 1968 model POH): Engage starter and continue to prime engine until it is running smoothly, or alternely, pump throttle rapidly over first 1/4 of total travel. Pull carburetor air heat knob full on after ...

Re: Pfizer Covid Vaccine shows 90% effectiveness.

How is it right when cases are at all time highs, all of a sudden now it’s time to open back up? Covid is proving to be more political than anything. No I can’t predict every turn of events but you don’t have to look to hard to see that this is less about the virus and more about politics. If you g...

Re: Carb fire season

Owkay... Let me rephrase: the OP didn't want to use the "pump the throttle" technique because the accelerator pump isn't designed to prime the engine. This makes me wonder if the primer is designed to prime the engine while it is already running. I was under the impression that priming sh...

Re: Carb fire season

This O-200 is configured with a primer nozzle on each cylinder injection port, rather than one nozzle above the carb, so I too was surprised that fuel could find its way back to the carb and airbox, but, they are down hill! Ah, ok. All the C150 POHs I can find say the primer injects fuel into the i...

Re: Carb fire season

I thought the standard primer injected into the manifold. That is what the POH shows anyway (although it might depend on model). How would fuel get from the cylinder back to the carb? Were you using the primer after starting? Did you pump the throttle at all? Just curious, so I can avoid the same th...

Re: Over Limit CHT

Just checked today: reducing throttle slightly in a full power climb has no significant effect on fuel flow (< 0.1gph), but CHT does start dropping. Although in this article it says the economizer jet only activates over 60-70% power: https://www.flight-mechanic.com/float-type-carburetors-economizer...

I find that on a hot day climbing at Vy results in about 430F, so I usually climb 20-30kt faster which normally keeps it around 400F, or I bring the power back to 75% after reaching 1000ft which also helps.
