3.1.1.5.3
Automatic Guidance Functions - During the automatic guidance functions, the
automatic flight control system - aircraft combination is an element within the overall guidance loop.
The requirements which this combination has to meet depend upon the performance requirements of
the guidance loop, the guidance method and the particular guidance computer. Unless specific per-
formance data are established in the applicable system specification, the following requirements shall
be met.
3.1.1.5.3.l
AN/SPN-10 Tie-in - All data stated below are for wing aircraft and shall
be met by the aircraft in the landing configuration and over the range of the expected weight, center
of gravity, and speed variations. The guidance control system shall be incremental pitch and bank
commands with respect to the trim attitude at the moment the guidance signals are inserted.
Pitch Control -
3.1.1.5.3.1.1
These requirements shall be met for step input commands up to + 5 degrees from trimmed conditions
at constant airspeed without changing trim and in the presence of noise as indicated in 3.1.1.5.3.2.5.
(c) The static gain K of the automatic flight control system, i.e,,
the ratio of elevator deflection to pitch attitude error, shall be
