A method (100) for operating a gas bearing (1), wherein the gas bearing is formed by a rotor (11) and a stator (12), wherein when there is rotation against a stator (12) with a lift-off rotational speed nL the rotor (11) changes from mixed friction with the stator (12) into fluid friction with a medium (13) located between the stator (12) and the rotor (11), wherein the rotational speed of the rotor (11) is kept at or above an idling rotational speed nI, wherein-in response to a first information item (21), on the basis of which a change ΔF is to be expected in the acceleration forces F acting on the gas bearing (1), a new value of a safety factor rN:=nI/nL between the idling rotational speed nI and the lift-off rotational speed nL is determined (110), and/or-in response to a second information item (31), on the basis of which a change ΔnL is to be expected in the lift-off rotational speed nL, a new value nL,neu is determined for the lift-off rotational speed nL (120), wherein the idling rotational speed nI of the gas bearing (1) is adapted to the changed value of the safety factor rN, and/or to the changed value nL,neu of the lift-off rotational speed nL, (130). The invention further relates to an associated computer program.
