steamchicken A thought - when we want to focus on the trend in a particular metric, we plot it on a chart like the DFDR traces. Strangely, aircraft displays show scrolling numbers or else multiple needles. Would a "value plus trend-line" be better? Medical monitoring displays do this.
even the interpretation of a medical monitor needs big experience, hehe we discuss since many weeks the lines of less minutos..... but in this case a trendline of the altitude, wouled helped the captain a lot to spot the situation (maby with a future-line calculation for different pitch or powers....?)
