Unhappy Is It Just Me...

...or do others have the same problem with EFIS IAS displays?

We don't require an IFR rating for the job, but are required to go under the hood every 3 months, 'just in case'. We also have a glass cockpit with what I assume is a "standard" IAS strip down the lefthand side with higher airspeeds moving down the screen past the reference line.

So here's the scenario. I'm under the hood trying to maintain 100kts. I notice that, due to a lapse in concentration, , that I am only doing 90.

Now, the speed that I want, ie 100kts, is above the reference line, and my natural reaction to move that down to the line, is to operate the cyclic trim in the same direction, ie towards me. But, of course that trims the cyclic back and we slow down.

Does anyone else do that. I have plenty of time on instruments, but on dials rather than EFIS.
