I'm pretty sure they ran the Airspeed Unreliable Checklist since they flew to 5,000 ft and retracted flaps per the PI-QRH for UAS. Why they added Flaps 5 is a bit curious as is why they failed to realize that flaps quieted the stabilizer trimming for a bit. UAS is one thing they may have anticipated based on the AFML?
