Airscrew systems for GURPS Spaceships

Note: the initial version of this post contained serious errors, giving far too much thrust per power point. The revised numbers below should give more plausible results.

Airscrew (TL 6) [Hull!]

One or more conventional aerial propellers or ducted fans, push air to provide thrust in atmosphere. Each system can use up to four (for ducted fans) or six (for conventional propellers) Power Points. Acceleration per Power Point is 0.05G at TL6, 0.1G at TL7, 0.12G at TL8+. Maximum air speed is 600 mph.

Airscrews are often installed as smaller systems (GURPS Spaceships 7: Divergent and Paranormal Tech, pp. 4-5) which can take one (ducted fan) or two (conventional propeller) power points.
