The L1011 was certified to 420. If a/c weight and ATC permitted, we would ocsnly get up to 410, with OAT’s of as low, in my personal experience, as -67C. We would optimally fly at the highest level for fuel consumption, commensurate with the most favourable meteorological conditions, winds etc. conducive to the most comfortable ride and the best ground speed, and comfortably within our max allowable weight for the altitude to avoid being too close to “coffin corner”.
