But apart from that, the '''oscilloscope''' itself may be an useful tool for developers and coders. Although I do not know any aircraft that has this instrument in its panel, the on-board engineer will eventually appreciate having it on hand at some point. | |||

{{cquote|I was just thinking today that it might be cool to have a built in grapher for simple / quick graphing needs. | |||
