Abstract
A gas turbine engine is operated from a gaseous fuel supply whose pressure may occasionally drop from a normal and comparatively high value. The acceleration limit schedule for the engine is established as a function of compressor discharge pressure but this schedule is modified as a function of fuel supply pressure so that, when lower than normal supply pressures exist, the engine may develop substantially the maximum power which is possible at the lower supply pressures.
