There is nothing about being a pilot that would reveal the shape of the earth to you. A previous moderator, TheEngineer, has testified to this as well as various pilots who have come by over the years.
Are you sure? There are few things that a light plane pilot might note and that's all TheEngineer flew.
But pilots that fly at much higher altitudes do note enough things for them to see that the earth is a Globe.
One of the most obvious is the "dip angle to the horizon". That is the angle the horizon is below eye-level, the observers local horizontal.
If the earth is flat the horizon must always be at eye-level (the "dip angle to the horizon" must be zero). Your own Wiki says so:
Basic Perspective
A fact of basic perspective is that the line of the horizon is always at eye level with the observer. This will help us understand how viewing distance works, in addition to the sinking ship effect. Have you ever noticed that as you climb
Samuel Birley Rowbotham also claims the same in,
Zetetic Astronomy, at sacred-texts.com, EXPERIMENT 10.Some flat-Earthers have correctly said this would not be quite true but it's close enough.
If, however, the earth is a Globe then the horizon is below eye-level by a predictable amount and pilots can certainly see that the horizon is a predictable angle below their eye-level or local horizontal.
It is true that the horizon seems to rise to eye-level but this is simply a result of perspective.
The simply because the
distance to the horizon is so much than the distance the observers
eye-level is above the horizon - twice one's height above the horizon.
There are plenty of YouTube videos of pilots and passengers measuring this dip angle to the horizon.
