From pointers to drums... From dynamics to numbers...

Tiny observations large outcome...

When I started flying ‘digital’ I missed and preferred the ‘old’ familiar dynamic moving pointers on the Airspeed indicators and Altimeters, rather than the relatively ‘dumb’ moving number-tapes and/or drums on the flight displays.

And my ‘emotion’ is not limited to Airspeed indicators and Altimeters only.

Of course, as with all sort of changes, I was told that I “just have to get used to it!”

OK... Fair enough... But, although I am getting more and more used to ‘flying digital’ by now, on occasion, I really sense the lack of instant dynamic ‘speed and altitude situational awareness’ that the ‘old’ analogue Airspeed indicators and Altimeters with their moving pointers will give us more or less instantly.

Looking at the tapes I have to figure out: Are the changes going up or down? Moving Fast or slow? Is it an increase or a decrease? What’s the trend? Things, that I would instantly be aware of with the analogue indicators. With digital indicators, however, I need more of my brain capacity to ‘translate’ the sheer changing of numbers on the rolling tapes (or drums) into dynamics.
