Starship Inter-Atmospheric Flight Cost

For discussion of the original 1978 rules and for the revised second edition that is entering development.

Starship Inter-Atmospheric Flight Cost

Most starships are just not structurally designed with inter-atmospheric flight intended. Since Aerodynamics is not a concern in space flight most larger starships are not designed and built with the idea that they will be entering a planet's atmosphere let a lone landing on a planet's surface. Most of the time teleporters and shuttles do the work of getting to and from a planet. However, there are some rare circumstances where a Captain may be forced with having to navigate his ship through an atmosphere or even putting down planet side. Here are some ideas on how to approach atmospheric entry and flight. (Please see my previous post on hull classifications for an explanation of terms used here).

Additional Power will have to be routed from the Hyperdrive to reinforce structural integrity and inertia dampening fields of a starship entering a planet's atmosphere. The Cost is calculated for the entire day but it is the same cost whether ship is in atmosphere for only an hour or the entire day. If a ship leaves the atmosphere into orbit or space and decides to re-enter the atmosphere they will have to pay the atmospheric flight cost again (Plus the cost for entering or leaving orbit)

10 EU per Hull Class Size x Gravity Difficulty = Energy Cost Per Day

Class 1: Low Gravity 10 EU, Medium Gravity 20 EU, Heavy Gravity 30 EU, Extreme Gravity 40 EU
Class 2: Low Gravity 20 EU, Medium Gravity 40 EU, Heavy Gravity 60 EU, Extreme Gravity 80 EU
Class 3: Low Gravity 30 EU, Medium Gravity 60 EU, Heavy Gravity 90 EU, Extreme Gravity 120 EU
Class 4: Low Gravity 40 EU, Medium Gravity 80 EU, Heavy Gravity 120 EU, Extreme Gravity 160 EU
Class 5: Low Gravity 50 EU, Medium Gravity 100 EU, Heavy Gravity 150 EU, Extreme Gravity 200 EU

So obviously a class one ship with only 50 ppb would not want to enter the atmosphere of an planet with extreme gravity because the cost in terms of energy would be too high.

The same table above could be applied as damage EU for a ship attempting atmospheric flight without paying the EU Cost to cancel out said damage.

A starship landing on a planet would have to be designed to do so or else the landing would be considered a controlled crash landing which would result in damage to the ship. Some exceptions maybe considered at the SM's discretion such as a controlled water landing (ST: Insurrection, ST: Into Darkness)
