The AP Upper mode captions in the 155 are ALT above the Airspeed tape and IAS above the Altitude tape which is confusing enough.
In the 135 they are the other way round. I asked the French pilot about this and he muttered something about "certification standards".
Scroll back and look at the pics.
Makes life interesting if you go from one to the other!!
Then again one aircraft is French and the other mostly German.
Methinks it is a small cock up somewhere that could lead to a larger cock up one day!
