It is interesting that no one has mentioned the different ability to recognise changing parameters using vertical strip indicators rather than clock style ones. On a clock style indicator one just has to glance at the position of the needle to recognise a relative value. On a strip indicator, one has to actually read a numeric value and then translate that into a value which is then compared with “normal”. For example, if the 3 o'clock position on a conventional ASI relates to Vy then a glance at the gauge will ring an unconscious bell saying “I am at the point where any reduction in speed will need more power to stop an increase in ROD”. A strip indicator requires one to read a digital value, convert it to an analogue mental model and then compare that with a Flight Manual graph before concluding a consequence.
Which option do you think is the easier processing function?
