==== Thrust to weight ratio ==== {{Main|Thrust-to-weight ratio}} '''Thrust-to-weight ratio''' is, as its name suggests, the ratio of instantaneous [[thrust]] to [[weight]] (where weight means weight at the [[Earth]]'s standard acceleration <math>g_0</math>).<ref name="sutton">Sutton and Biblarz 2000, p. 442. Quote: "thrust-to-weight ratio F/W<sub>0</sub> is a dimensionless parameter that is identical to the acceleration of the rocket propulsion system (expressed in multiples of g0) if it could fly by itself in a gravity free vacuum."</ref> It is a dimensionless parameter characteristic of [[rocket]]s and other jet engines and of vehicles propelled by such engines (typically space [[launch vehicle]]s and jet [[aircraft]]). If the [[thrust-to-weight ratio]] is greater than the local gravity strength (expressed in ''g''s), then flight can occur without any forward motion or any aerodynamic lift being required. If the thrust-to-weight ratio times the lift-to-drag ratio is greater than local gravity then [[takeoff]] using aerodynamic lift is possible.
