While I agree that mass affects time such as the even horizon of a black hole where time stops, I believe the time rate difference in satellites and planes is caused more by speed rather than mass.
As an object's speed increases, time slows down and as the same object's speed increases, it's mass increases as well.
You've got that wrong. Satellites and planes time dilation is due to gravity. Time dilation due to speed is less noticeable until you get significant fractions of the speed of light. It's almost a flat line until you get to 50% then from 90 to 100% the chart turns near vertical.
Okay, I stand corrected. I'm slow because I'm been mostly laying on my back rather than standing up. I don't mind learning something new. I did fact check you using ChatGPT. I use it for a lot of research. I know it does often come up with factually incorrect answers that are sometimes contradictory with an immediately preceding answer it gives.

What affects the time rate difference of planes and satellites more compared to time on the surface of the earth - is it the relative speed or the mass of the earth? Give references and citations.

Both the relative speed and the mass of the Earth have an impact on the time rate difference experienced by planes and satellites compared to time on the surface of the Earth. However, the dominant factor in this context is the gravitational potential, which is directly related to the mass of the Earth.
According to the theory of general relativity, clocks in regions with stronger gravitational fields run slower compared to clocks in regions with weaker gravitational fields. This effect is known as gravitational time dilation. The closer an object is to a massive body, such as the Earth, the stronger the gravitational field and the slower time passes.
The time dilation due to gravitational potential is more significant for planes and satellites compared to the time dilation due to relative speed (special relativity) because the speeds of planes and satellites are relatively low compared to the speed of light. The gravitational time dilation effect dominates in this scenario.

These references provide detailed explanations of the concepts of special relativity and general relativity, including the effects of relative speed and gravitational potential on time dilation. They support the understanding that the dominant factor affecting the time rate difference of planes and satellites compared to time on the surface of the Earth is the gravitational potential, which is determined by the mass of the Earth.
