`LABEL`	An alphanumeric string of up to eight characters used to identify the degree of freedom. 1 (String)

Comments

The degrees of freedom defined with this entry represent rigid body motion in the reference coordinate system defined on the AEROS entry. The standard labels that define the various rigid body motion are:

Table 1. Standard Labels Defining Rigid Body Motions
LABEL	Degree of Freedom Motion	Description
ANGLEA	$u_{r}$ $u_{r}$ (R2)	Angle of Attack
SIDES	$u_{r}$ $u_{r}$ (R3)	Angle of Sideslip
ROLL	${\dot{u}}_{r}$ ${\dot{u}}_{r}$ (R1)	Roll Rate = pb/2V
PITCH	${\dot{u}}_{r}$ ${\dot{u}}_{r}$ (R2)	Pitch Rate = qc/2V
YAW	${\dot{u}}_{r}$ ${\dot{u}}_{r}$ (R3)	Yaw Rate = rb/2V
URDD1	${\ddot{u}}_{r}$ ${\ddot{u}}_{r}$ (T1)	Longitudinal
URDD2	${\ddot{u}}_{r}$ ${\ddot{u}}_{r}$ (T2)	Lateral
URDD3	${\ddot{u}}_{r}$ ${\ddot{u}}_{r}$ (T3)	Vertical
URDD4	${\ddot{u}}_{r}$ ${\ddot{u}}_{r}$ (R1)	Roll
URDD5	${\ddot{u}}_{r}$ ${\ddot{u}}_{r}$ (R2)	Pitch
URDD6	${\ddot{u}}_{r}$ ${\ddot{u}}_{r}$ (R3)	Yaw

The degrees of freedom defined with this entry are variables in the static aeroelastic trim solution, unless they are constrained by referencing them with a TRIM Bulk Data Entry.
