Area between equilibrium and downflooding or the second intercept to be > 0.0025 (equ - 1) m-rad. |

`46 CFR 171.080 (f) (6) (iii) requires the area between equilibrium and `downflooding or the second intercept to be > 0.0025 (equ - 1) m-rad. `This variable area requirement can be calculated and used in the limit `definition. Since the limit is static after the limit command has been `issued, it must be updated by the MXmacro for maximum VCG calculations. `The following run demonstrates how this can be done. `Download GF from: 171080F6.zip read 171080f6.gf report /nograph crtpt = "Downflooding point" 70, 15, 15 hmmt 2000 type (cmpt1.s,cmpt2.s) = flood variable A,H `temporary variable used by Macro lim macro lim limit (1) angle at EQU < 15 `f6iii limit (2) angle from EQU to RA0 > 20 `f6iiiA variable A,H set H = ABS {HEEL} minus 1 set A = {H} times 0.0025 `(area units in m-rad) if {A}<0.004 then set A=0.004 `minumum required area for this limit limit (3) area from EQU to RA0 or FLD > {A} `6fiiiB / angles 0 2 .lim MAXVCG 6,8,10 /trim:0/MXMACRO:LIM MAXVCG 6,8,10 /trim:0/MXMACRO:LIM /TOL:0.002 print preview report off |
