What is the current behavior?

There are no utilities for dispersion analysis.

What is the new behavior?

Utilities are added to allow easy visualization of the results of dispersion analyses. One can simple pass a list of Flights to plot_dispersion. Each flight trajectory is converted from the time domain to the non-dimensional time domain (non-dimensionalized by the duration) and interpolated to a standard number of points (default 1000). Then mean, and standard deviation (in z-axis only) flight trajectories are calculated. Finally, all trajectories are plotted. Real trajectories are plotted in black. Statistical trajectories are plotted in red.

Does this introduce a breaking change?

• Yes
• [*] No

Other information

This could definitely use some tests. Also, it introduces a lot of new utility functions.

Great work @SullivanMuse! This is a great solution to the problem. Kudos for normalizing the time vector and making sure to make time steps uniform.

I ran your notebook here with some more flights and kept getting a great result:
