B.
T-45 has conventional rudder
Sg 1, fr 4
Conventional Control
System
1.
Aerodynamic forces may feed back to rudder pedals
2.
Rudder pedals will be displaced due to side loads
during post stall gyration or spin
3.
Up to 300 pounds of pressure may be required to
counter air loads on rudder during post stall gyration
or spin
