The maneuvering Speed (Va) can be computed as the (SQRT(G limit)) = times=20 Vs so that the new Va is reduced to 132 Kts.
 
**You have applied the 3.2G limit in this calculation. While that = may=20 seem appropriate, we know that the tested L-IV wing load limit is=20 significantly higher than that. Therefore, the application of the 3.2G = limit=20 may not be necessary. If we take the 4.4G limit, knowing that the = airframe is=20 strong enough to support it, then Va should increase to 157kts, not = decrease=20 to 132 kts.
 
** Any of us who recall flying Wichita spam cans will recall the = Va=20 placard, which always has Va lower at light weights.
