3.5.4 Flight control subsystem performance. - The flight control subsystem shall be capable
of converting command intelligence from the guidance subsystems into appropriate control
device operations for executing the flight maneuvers specified in the detail specification.
3.5.4.1 Compatibility with missile airframe and control devices. - The flight control
subsystem shall be capable of executing specified flight maneuvers over the entire range of
mission requirements utilizing only the missile control devices specified in the detail
specification. The execution of these maneuvers by the flight control subsystem shall not
exceed any structural limit of the missile airframe nor exceed the missile's aerodynamic
capability. Mission requirements shall include, but not be limited to, the following:
a. Missile operating altitude
b. Missile airspeed
c. Missile flight time
3.5.4.2 Stability. - The flight control subsystem shall be capable of maneuvering the missile
onto a directed change in flight path such that the transient conditions resulting from this
maneuver will decay as rapidly as possible. Furthermore, the flight control subsystem shall be
capable of maintaining the missile on a directed flight path to the greatest degree practicable
while it is subjected to external disturbances.
3.5.4.3 Accuracy. - The flight control subsystem shall be designed and constructed such that
it is capable of maneuvering the missile to follow a directed flight path or to intercept a
terminal target within the limits specified.
3.5.4.4 Adaptive flight control subsystems. - When conventional linear control techniques
fail to meet the flight control subsystem requirements specified herein over the ranges of
mission requirements specified in 3.5.4.1, adaptive techniques may be employed. These
techniques may include changing processing unit parameters or mode switching as a function
of missile altitude, airspeed, or other parameters. Such adaptive flight control subsystems
shall be in accordance with the detail specification.
3.5.4.5 Nonlinear subsystems and equipment. - When the flight control subsystem utilizes
nonlinear techniques and equipment in its design for the purposes of performance
improvement over a wider range of control conditions, such nonlinear designs shall be
approved by the procuring activity.
3.5.4.6 Processing units. - The flight control subsystem shall have processing units which
will correctly operate the missile's control device actuators to execute specified maneuvers in
accordance with related input signals. These input signals will consist of command signals
from the missileborne guidance subsystem and feedback signals relating to the missile's
attitude, position, and condition from missileborne sensors. These processing units shall be
compatible with related processing units and with other missileborne equipment. Their
