Sure they can. there is lots of evidence that you can observe yourself to demonstrate the Earth's curvature. There's no need to take anyone's word for it. Watch a ship disappear over the horizon -- from the bottom to the top. Glad you brought that up. It's perspective, waves blocking, and visibilit...

Thank you for re-inforcing my comment about you following typical conspiracy theorist behavior. You utterly ignore context and use a small snippet of information to back your arguement. Small snippet? The entire article is about creating images of the Earth. Why the hell don't we have an entire, si...

Well other than the fact that I never mentioned gravity in my previous response, a few screenshots of a spreadsheet aren't enough for me to agree or disagree with you. The lines you've drawn are quite useless to me as in scale at least they are grossly misrepresentative. Forget my lines, look at yo...

Have you read the details from the beginning of this thread about gravity, the ADI, the curved climb vs. straight climb, no stick inputs vs stick inputs required? Have you? The clouds don't move in that "live feed". Clouds are ever-changing, over minutes of time. I'll look for the time-lapse showin...

NASA has NEVER shown an image of the earth that was not CGI or composite. It's clearly printed on their website. By 2002, we finally had enough data to make a snap shot of the entire Earth. So we did. The hard part was creating a flat map of the Earth’s surface with four months’ of satellite data. R...

The scientists, and a whole lot of people who are a lot smarter than me, tell me that the earth is round (Ok, oblate spheroid) ... Again, good enough for me.. They tell you , but they can't show you . Is that good enough? Have you read the details from the beginning of this thread about gravity, th...

Oh for **** sake... You're going to pull out that arguement? That isn't how "Seeing the curve" works. For the sake of brevity: Learning2Fly: Do you believe the planet is a big ball-shaped object or a big flat disc-ish thing? Nevermind seeing the curve, I plotted aircraft data that doesn't agree wit...

Jeebus on a bicycle! Is this still going on? And now the flat-earthers are in on it, too! :rolleyes: Next y'all'll be talking about variable tailwinds... Yes sir, can you explain this stuff? We have all of these expensive and accurate flight instruments plotted on a graph that do not support your m...

Two members on page 5 (Chris M., and KevinD) agreed that the climb profile should be curved with respect to gravity, otherwise the flight instruments and control inputs don't coincide. So now we have two pilots vs. two pilots stating different perceptions of the flight profile. Which is it? So then ...

Ok, I don't see what's surprising about what you just posted. A straight line climb with respect to the earth is the same thing as a constant climb with respect to MSL, which is a curved path looking at it from space, since both the earth and MSL are spherical (approximately). What point are you tr...

Prelim results are posted. Again, I say interesting. I think I need to use LAT/LON co-ordinates to get a more accurate total ground coverage, but this is a decent start. LON appears to be way off from Airport chart? Starting elevation is 12.1 feet different from chart which I believe is within spec ...

There isn't much out there in NTSB land that shows a complete animation of take-off to cruise alt. I found one animation that we can use, along with flight data. We all agree that a green line is good; curving while ascending which indicates gravity. If we see an altitude profile that resembles the ...

And altitude is measured from MSL so why would you want to compare altitude to MSL?

Sorry, I meant altitude profile using MSL values.

Pressure altitude, yes.

profile of altitude vs. MSL.

]Going to look back at those NTSB flight data animations. I'm pretty sure those climb outs had a straight line to cruise alt Frame of reference. Straight line to our frame of reference which is sea level and gravity. Looking from out side the frame of reference, it would be curved, inside it is str...

Just had a wicked thought.

If friction produces heat how long should it take for a dog to hump a pail of water to a boil? Hey smart guy, can you tell me how the VSI indicates ft/min? Apply your answer to a curved ascent, while gravity is pulling the aircraft over the curved Earth. I don't ever remember the instructor drawing...

the trim will require resetting constantly. So you could run out of trim, before you ran low on fuel? I must flight plan a route only so long as can be flown before I run out of trim range! I've never seen that in a flight manual! Then our perception of constant climb cannot be a straight line as s...

Digits, According to the engineer in the video, the trim will require resetting constantly. You can't just aim the aircraft without elevator inputs because the Earth continues to curve, and gravity will continue to pull the aircraft off pitch. If you were to neutralize the force, the elevator would...

He asks a valid question: Why are you not making constant corrections on the yoke (pulling back) to main...

It seems to me that you should stop thinking about this, and simply accept that these instruments work perfectly fine as intended No, I think I should continue thinking about this and you should as well. You're not accounting for the small, constant forces that I have described which will confuse t...

^ Right, but again, the small forces over extended periods would confuse the instrument. For example, a rotation of +/-1 or 2 degrees in pitch, or bank over 20 miles of ground would activate the erection system. The ADI would self correct with the force of gravity, and the scenario repeats constantl...

Thanks Steve, Having an electronics background helps me understand that force inputs outside of the filter cut-off will not be transmitted to the erection system for correction. In my mind, using a tunable bandpass filter would be even better to cancel out sub forces below the operating envelope of ...
