To get a Load Factor of 1.0 in a 60° banked turn, your vertical component of lift is half the total weight.
To get a stable descent when L = 0.5W, your coefficient of drag will have to be
substantially larger than coefficient of lift.
There are two ways to get CD higher than CL: fly very fast or very slow!
Very fast - probably above Vne. Oops.
Very slow: probably a stalled condition - spinning yes?
