Narrative:
We were on a descending via on the eagul arrival into phx with 7;000 ft set to comply with the hiney restriction. At geeno the airspeed went to 210 KTS which was below maneuvering speed for our configuration. We were unable to comply with the flap/speed policy and will not be able to on all the VNAV approaches we reviewed. Luckily we had one of our FAA aircrew program managers (apm) on the jumpseat doing a ride along. The three of us were able to 'stabilize' the situation and safely land the airplane. Operations need to review the flap/speed policy as it pertains to VNAV arrivals.
