mission_analysis: correct output of deceleration step before descent to approach

Feature Request

Summary

If the CAS at top of descent is above CAS given in descent speed schedule above FL100, the aircraft decelerates first before descent. During cruise iteration, some descent simulations are taken to estimate the final descent range to begin descent early enough. It seems that for this simulation, the ouput for deceleration is also written to log file, which is not needed. Please suppress this type of output when in simulation mode.

In addition, the wrong mode is written to mission_.csv file. In the file the deceleration step is named "descent_to_approach" instead of "change_speed"; please correct it

Why?

It is confusing to the user that it seems the aircraft is decelerated but indeed it is not

Acceptance Criteria

• No output of deceleration in cruise with constant Mach step
• Corrected output of mission mode in mission_.csv to use "change_speed" instead of "descent_to_approach"
