`A2/A1>1
limit residual ratio from ABS {T1} to ABS 30 OR FLD > 1

`TR-T2>20
limit angle from ABS 30 TO FLD > 0
limit angle from ABS 30 TO RA0 > 20

`Note: The angle 30 degrees as used above is conservative.
`For a method of finding the angle Theta3, see THETA3.
`However, note that Theta3 will vary and hence the Limits
`will have to be redefined for each draft.
