In the Groundroll (AB) phase of Takeoff, mass drops to 500e3 instantly when groundroll AB phase starts

[tjhalloc]

Description

There is an upper limit on mass set in aviary/mission/flops_based/phases/groundroll_phase.py, line 89 states an upper limit of 500e3 for aircraft mass. Raising this limit above the mass of my aircraft (656e3) resolved this issue.

Example

    phase.set_state_options("mass", rate_source="dmass_dv",
                            fix_initial=True, fix_final=False, lower=1, upper=500.e3, ref=100.e3, defect_ref=100.e3, units='lbm')
