So I select the IAS BUG to 250 for example, select altitude, and engage IAS. Plane levels off correct altitude yet the speed does not maintain 250 selected when IAS engaged.

Is this a error bug? Or am i doing something wrong.. and yes, i red the manual =/
 
Please help!
 
Is the avro ment to be controlled manually? (thorttles)

No auto throttle on the 146.....have to set power using the throttle.  Good description from page 45:
Now press the ALT ARM button followed by the IAS button. The autopilot will now vary
the vertical speed in the climb to 27,000ft to hold 230 knots. Do not confuse this with the
auto-throttle or VNAV systems on board modern airliners. The autopilot will not alter the
throttle position; it will simply alter the aircraft pitch to maintain 230 knots at the current
throttle position. For this reason, throughout the climb, you must monitor both your
airspeed and throttle position (or N1 engine instruments).
