So, if I understand it right from reading forums: 1. You put a thruster device on your flying vehicle. An UL thruster decays 9 pec, a L thruster decays 10 pec and a light L thruster decays 0.01 pec, when you leave Arkadia atmosphere. 2. Flying through Space to Calypso costs around 80 pec of fuel. 3. You pay 2 PED landing fee and another 9/10/0.01 pec thruster decay to go through Calypso atmo and land. One way trip costs around 3 PED. The current price on a (L) Thruster is about 100 PED and it lasts 49 jumps, so every travel through the atmo costs you about 2 PED. The total price of one way trip with a (L) Thruster between Arkadia and Calypso is about 7 PED.
