Base time for regular start is Minutes equal to the object length for the ship SM. (10 min for sm 4, 15 for sm 5, 20 for sm 6 and so on) and requires Pilot(High performance space craft), Electronics Operation(sensors),Mechanic(spaceships), Mechanic(Reactionless), Mechanic(Fusion Reactor) rolls. Failure by 1 or 2 still succeeds, but you do not notice any eventual problems.

This requires as many crew as indicated in the ship entry. Having less crew means that people need to do multiple tasks an take a longer time. You can also freely take extra time and get time bonuses. You can do any part or all faster by taking -1 to the roll for each -SM time unit.

Roll a HT roll for the ship on each start. On fail see below for effects. The problems are noticed on the skill rolls rolled above.

If the ship is on standby, divide time to start by 10.

Each takeoff and landing roll HT roll. On fail see below for effects.

pilot: piloting(space)+ship HND

if landing beacons+orbital control nothing else needed(+2 to piloting each).
Else: Electronics operate(sensors): success +2 to pilot, fail -2 to pilot if no landing beacon. Navigation(space), success +2 to pilot, fail -2, if no Orbital control.

If takeoff: +2 for known start location, +2 for orbital control. Else: Navigation(space), success +2 to pilot, fail -2, if no Orbital control.

If you multi task you get -2 to all tasks/extra

Remember that ships also needs the maintenance
Each day in transit roll HT roll. On fail see below for effects.

Normally: pilot+sensor op regardless of need. (1/3 normal crew, minimum 1)
Pilot (no rolls needed if piloting 12+, else roll at +4/hour of maneuvers or 24 hours of coasting)
Sensor Operator(no rolls needed if electronics operate(sensors) 12+, else roll at +4/hour of maneuvers or 24 hours of coasting) But if there is an encounter, the detection is rolled by the sensor operator.
Engineer (no rolls needed if mechanic(spacehip) 12+, else roll at +4/hour of maneuvers or 24 hours of coasting)

If you multi task you get -2 to all tasks/extra

Navigation:
Normally takes 1 hour of navigation calculations to jump, roll at +4(computer support)-1/parsec plotted jump length divided by TL mod, where TL mod=1 for TL9, 2 for TL10, 4 for TL11.

Each hyper space entry roll HT roll. On fail see below for effects.

Normally: pilot+navigator+sensor op regardless of need
Navigation(hyperspace) : critical fail → wrong place and pilot at -2, Fail → need to recalculate, success → normal pilot. Critical success: -5% travel time, +1 piloting. Hyper calculation takes 1 hour normally.
Pilot(Hyperspace): critical fail: hit something. Fail: no entry. Success: entry. Critical success: -5% travel time.

Remember that ships also needs the maintenance.
Each day in transit roll HT roll. On fail see below for effects.

Normally 1+ on watch (1/6 normal crew, minimum 1) Need someone on watch. (no rolls needed if electronic operation(sensors) or piloting(hyperspace) 12+, else roll at +4/24 hours), if no one on watch roll at the typical ship computer default skill of 3 at +4=7..

In most cases: Failure forces a HT roll at -5
Sensor watch roll failures in normal space cause a collision: roll 1d: 1-3:really small: 1 hp object. 4-5:small:1d hp object 6:reroll and multiply by 1d.
Sensor watch roll failures in hyper space cause a drop out of hyper and a HT-2 roll for hyper space generator.

All ships have a maintenance requirement.

Typical skills needed: spaceship_maintain_repair

For SM +10 or larger Look up the workspaces in each module and the repair skills for that module. Each module needs 20 hours of maintenance*workspaces/week using that skill.

For lower SM ships use table below for each system required maintain/week. If there is no engine room, double the time required and the maintenance must be preformed externally.

Someone with skill 12+ must spend that time maintaining the system(Note that extra time gives a bonus, thus if you have a skill 10, you could spend four times normal time to get +2 and thus make it effective skill 12). If some system gets too low maintenance it reduces the ship HT rolls by -1/starting 100% of total maintenance requirement*weeks not maintained.

One can leave systems on standby, they require the normal maintenance at 4 times normal interval.

Ships that have been on storage long time also require maintenance. Maintenance requirement for a turned off ship is: 1/16th on normal planetary surface(=1.25hr/person listed/week), 1/64 in vacuum, proper hangar or other protected conditions(=16.25 hr/person listed/yr). 1/256(=4 hr/person listed/yr) if in protected condition and specially prepared for long term storage taking 10*normal weekly maintenance time, such ships will also require 5*normal weekly maintenance time to reactivate in addition to the maintenance. All that missed maintenance should be done before starting such ship.

The different things above call for HT rolls. All but start roll allow a save to be made: Roll against the appropriate skill of the one who did the previous maintenance on that component. On success nothing happens, but the near failure is clear and if no maintenance done until next failed HT roll the maintenance roll is counted as failure unless the maintenance roll was a critical success. On fail, lookup the HT roll result, on critical failure shift result to one worse:
Critical Success: Next 1d HT rolls will succeed automatically.
On Fail: some system has a problem that has to be corrected. Roll random system, all actions with it are at -1/fail by. Fixing it requires +0 roll with suitable repair skill and (HT roll fail by)^3 minutes for as may people as are the system crew(minimum 1). Parts need is: fail by-1d%.
Critical failure: one system fails badly and requires 3d% parts to fix and 3d hours for as may people as are the system crew(minimum 1). 1d other systems fail as under fail. Roll 1d each to get “fail by”.
