The invention belongs to airborne display technologies and relates to a simulated roller display method for airborne liquid crystal displays. The method includes: step one, determining a step size according to data characteristics and actual interpretation effects, wherein the step size refers to a minimum step size in quick rolling of a numerical tape, the data characteristics refer to physical jump limits of actual data parameters, an approximate step size range is determined according to the data characteristics, and the step size is finally determined according to the actual interpretationeffects; step two, interpreting an absolute value of displayed data in a last period and current actual data difference, and processing according to a relation between the absolute value and the stepsize. By simulation of roller characteristics of mechanical instruments, a display mode of the numerical tape is improved, a data smoothing algorithm is added, the numerical tape always rolls to an actual numerical value in a roller manner when a data source is in high fluctuation, and accordingly directness and accuracy in data display are realized, interpretation influences are eliminated, andvisual fatigue of pilots is greatly alleviated.
