Page 88 of TW used to have a line about units needing a Safe Thrust above (not equal to) 2 to take off. Errata 4-4 deleted this sentence, and didn't replace it. As written, this implies a unit with a Safe Thrust of 1 (0.5 G) can take off in any mode (horizontally or vertically) from any planet. StratOps is silent on a hard limit, but Errata 2-1 does insert a section on page 72 requiring a fuel point per 0.5 G of local gravity for vertical take off. This could be interpreted as an implicit limit for vertical liftoff, but seems to permit Maximum Thrust.
Questions:
1) Can an Aerodyne unit with a Safe Thrust of 1 liftoff (horizontally, in atmosphere), regardless of the local gravity?
2) Can Maximum Thrust be used to liftoff?
