Most descents can be made from cruise by simply reducing power and using that to control rate of descent
In the Archer II you will need to set power to 2500RPM and then descend at 122 KIAS to attain the performance as listed in the AFM
If using idle power descents you should briefly increase power every 30 seconds to &quot;clear the engine&quot;
To level off from a descent you should use the same 10% of VSI rule as you would for climbs
