 In `general` you can decide how the needed fuel is estimated and you can tell **mission_analysis** in which way it shall behave in different flight segments.


-The `mode` node lets you choose the methods that are applied. Using the keyword `low`/`mid` you will trigger the low-fidelity/mid-fidelity version of the [Standard Mission](methods.md) method. It also has three sub-methods to differentiate between `design_mission`, `study_mission` and `requirements_mission` which can be selected in the `mission_type` node. Please mind that the low-fidelity method only accepts the `design_mission`. The `rate_of_climb_switch` will only affect the [Climb to Ceiling](mission_steps.md/#climb_to_ceiling_subparagraph) step of the `requirements_mission`. With this option, **mission_analysis** calculates the optimum rate of climb towards service ceiling.

Please mind that the low-fidelity method only accepts the `design_mission`. After the first iteration, the [Weight and Balance tool](../performance_assessment/index.md) delivers a center of gravity position in relation to the aircraft mass (center of gravity shift due to defueling). To take that into account, you can activate `interpolate_polars`. For kerosene based propulsion, the effects are rather small, but once H2 is involved you should consider using it. Furthermore, the `rate_of_climb_switch` will only affect the [Climb to Ceiling](mission_steps.md/#climb_to_ceiling_subparagraph) step of the `requirements_mission`. With this option, **mission_analysis** calculates the optimum rate of climb towards service ceiling.
