Suggestion: Better Trip Planner

[TechieV]

Problem:
 When I play KSP 1 and 2, I must always exit the game, go to the web, find the KSP delta-V map, and calculate the delta-V to do a mission. It feels very inconvenient to me! KSP 2 already has a trip planner to stop this exact inconvenience, but I can't change much about the delta-V prediction. I can only change the target celestial body, and whether it's one-way, or a round trip. The planner always calculates the delta-V from the starting body's ground to the target's ground (and back again if "Round Trip" is chosen). I can't add or remove delta-V counts or remove the "Kerbin Orbit" dV count to only show the payload's dV budget.

My Idea:
 My idea is a Trip Planner system where you can add or remove dV counts. My idea is a list of celestial bodies with dV counts for any manoeuvre, such as "Flyby" or "Insert into Orbit". Once the action is clicked or "Drag-and-dropped", it goes to a list, where the dVs are added to make a dV budget.

Benefits:
This idea would solve the inconvenience with the online dV map AND upgrade the Trip Planner. I think it would be useful for the later milestones of Early Access, with the other star systems, as more flexibility in planning trips would be needed for the interstellar voyages. 

I hope you like this!

I would agree but also changing the starting celestial body, the starting condition as well as the ending conditions.  For example, suppose I am building a lander that needs to get from Duna Orbit to the surface and back to orbit.  This is impossible to do with the trip planner.

I would be necessary to control:

• Adjusting my starting delta-V to plan things like return trip segments.
• Determine which segments should be vacuum Isp vs. atmospheric Isp instead of them all being the vacuum.
• The starting celestial body
• The starting situation such as being landed or in orbit
• Accounting for aerobraking to reduce delta-V requirements pulling into orbit or landing.
• Using fully propulsive or parachutes plus propulsive thrust when landing (Ex: Duna).
• Adding intermediate celestial bodies and situations
• The ending celestial body
• The ending situation.

I should be able to plan starting from the Kerbin launch page, getting to orbit, transferring to Duna, and aerobraking into a circular orbit.  Then transferring back to Kerbin and aerobraking using a skip re-entry and landing using parachutes.

Amazing! That would make the Trip Planner even better. Plus, a seperate dV input could be added to add other amounts of dV, for things like safety margains or fine-tuning. Now I'm craving for this to be implemented!

Needed to add the "seperare dV input" idea to the reply.
