Abstract
A system and method for flight chart font character scaling is disclosed. A host computing device is configured to: detect a font character size of a font character in a flight chart file, associate a threshold zoom level with the font character based on the respective font character size, and convert the flight chart file to aircraft display hardware directives. An aircraft display is configured to display a flight chart using the aircraft display hardware directives. An aircraft computing device is configured to detect a current zoom level of the aircraft display, compare the current zoom level to the threshold zoom level, set a drawing mode of a font character reference as a stroked mode or a filled mode, and present a referenced character as a filled character or a stroked character based on the drawing mode.
