Abstract
A take-off safety indicator for an aircraft has a double movement meter with a crossover pointer indication. The meter movements are driven respectively by inputs representative of speed and distance along the runway. The crossover point follows a locus and the optimum locus is shown on a background card selectable from a number of cards in dependence upon prevailing conditions.
