G-Tolerance

Humans and other human-like races tend to have similar tolerance to acceleration. A acceleration of up to about 2 G on a relatively constant basis, though no more than 1.5 G is preferable for most people. For a short time (a couple of minutes) people can take g-force loads of up to 4 or 5 G. Training and special clothing can extend this to around 10.5 G for up to a minute. Any more than this and humans and other human-like races will tend to suffer medical conditions including black outs and worse (worse depending on actual G load and time period under that load). Even a second at say 45 G is likely to cause permanent damage along with causing a black out, though the shorter the time below 1 full second the higher the rate of survival. A accident can cause as much as 300 G, but it only lasts a fraction of a second and so is survivable as far as g-tolerance goes.

This directly limits TL 6-10 aerospace craft. Acceleration of only 32 feet per second is 1 G, aircraft and spacecraft both tend to be capable of more than 32 feet in a second of acceleration. However the body of the pilot often can only take so much. The equivalent of a WWI era tri-winged fighter plane can do 7 G in a dive and that often caused black outs in pilots. The impact of this is that most vessels simply cannot travel very fast because they are limited by acceleration. This in particular effects space flight and robotic vessels become a much easier choice for exploring the solar system.

Getting around G-tolerance limits.

Gravitic technologies and other techniques starting @ TL 10 start to allow acceleration beyond human tolerance.

Ejection & Escape Pods

Smaller vessels like fighters, bombers, and gunboats tend to have cockpit ejection capsules or individual ejection seats. Larger vessels have escape pods or life boats. Escape pods typically have small engines and seating for about 4 people. Life boats have seating for a dozen people & are engineless shuttles (it does have thrusters though) capable of glide landing on a planet. Both have only basic support to last their intended capacity for about 1 month.

Gravity

Simulating gravity on larger vessels is common as weightlessness has health concerns over the long term and requires exercise facilities to maintain muscle tone. For these reasons designs would incorporate spin gravity sections or use constant 1 G acceleration & deceleration to imitate having gravity. More advanced designs can use gravitics to provide artificial gravity.

Time and Ship Watches

Time in space was standardized during the League Era to a 24 hour clock as it made a good average of the day cycles of most races. On ships this was split up into 3rds, or 8 hour shifts, and one would have 8 hours to sleep, 8 hours to work, and 8 hours to themselves. This will be either split with 1st & 3rd shifts at midnight or 1st and 2nd shifts at noon. Most officers on a spacecraft however are ‘on call’ and if there is an alert they are supposed to go to their duty stations regardless of what else they may have been doing.

A few groups use 24 hour clocks with 4 shifts of 6 hour shifts and others do 2 massive 12 hour shifts, but these are rare. Only a few races use less or more than 24 hours, or round their planetary time of 22-26 hours to be 24 so it is easier to divide. Currently no race has a clock of more than 36 hours and no less than 18.
