"d acceleration.\n  The second input contains external forces and moments in b"
"ody axis.\n  The third input contains the deflections of elevators, ailerons,"

      MaskHelp		      "<p>\nThis block is a general nonlinear 6DOF air"
"craft model, with a very accurate built-in atmosphere model and constant aero"
"dynamic derivatives. \nThe architecture of the block is largely based on the "
"Aircraft block provided by the <A \nHREF=\"http://www.mathworks.com/matlabcen"
"tral/fileexchange/loadFile.do?objectId=252&objectType=file\">FDC toolbox</A> "
"(Marc Rauw, 1993-2000).\n</p>\n<p>\nThe geometric and inertal data of the air"
"craft are entered as parameters in the first row of the mask. The other six r"
"ows contains the \nnon-dimensional aerodynamic derivatives. The last row is t"
"he initial state.\n</p>\n<p>\nThe first input contains the wind velocity and "
"acceleration. \nThe second input contains external forces and moments in the "
"aircraft body axis. \nThe third input contains the deflections of elevators, "
"ailerons, rudder, \nand flaps or stabilators. For a list of outputs look unde"
"r the mask. \n</p>\n<p>\nThe control surface sign conventions are the same ad"
"opted in books such as Stevens-Lewis and Etkin, and in many flight simulators"
", \nincluding the FDC toolbox. <br> \nSpecifically, positive elevator deflect"
"ion causes negative pitching moment (Cmde &#60 0), positive rudder deflection"
" causes negative yawing \nmoment (Cndr &#60 0), and positive aileron deflecti"
"on causes negative rolling moment (Clda &#60 0). Another way to say the same "
"thing is \nthat, the positive elevators deflection is Trailing Edge Down (TED"
"), the positive rudder(s) deflection is Trailing Edge Left (TEL), and, \ntaki"
"ng as TED the positive ailerons deflection, da=K*(da_right-da_left), with K u"
"sually equal to 1 (FDC) or 1/2.\n</p>\n<p>\nSince this block is largely based"
" on the FDC toolbox, i redirect you to the FDC Toolbox manual, for a good exp"
"lanation of the underlying \ncomponents. Besides the mask and the fact that t"
"he aerodynamic derivatives are expressed in the stability axis, the only rele"
"vant difference \nwith the FDC toolbox is that in the computation of the aero"
"dynamic forces, q is normalized as q*cbar/2V instead of q*cbar/V. The majorit"
"y \nof aeronautics books that i've seen use q*cbar/2V.\n</p>\n<p>\nPlease not"
"e that the International Measurement System is adopted. So, lengths are in me"
"ters, masses in Kg, and inertia moments in Kg*m^2. \nMoreover, forces are in "
"N, moments in N*m, accelerations in g, and angles in radians. For those that "
"use the english system, here are some useful \nconversion factors: <br>\n1 ft"
"   = 0.3048 m, 1 lb   = 0.4536 Kg, 1 slug = 14.593903 Kg ,  1 slug*ft^2 = 1.3"
"55818 Kg*m^2 \n<br>\n</p>\n<p>\nFinally, there is an <A HREF=\"http://www.aae"
".uiuc.edu/m-selig/apasim/Aircraft-uiuc.html\">excellent source</A> of aircraf"
"t aerodynamic data \nwhich is mantained by Michael S. Selig, Rob Deters, and "
"Glen Dimock at the university of Urbana-Champaign. To use any of the given mo"
"dels \nyou just need to type the supplied aircraft data in the block mask.  "
