MOC VTOL.2270(b)(1) Emergency landing dynamic conditions n/a This MOC provides a set of general design conditions that, when used in their entirety, are accepted to ensure adequate protection of occupants against injury in dynamic conditions that are likely to occur in an emergency landing. (a) CS 27.562(a) Amdt. 6 is accepted as a means of compliance. (b) CS 27.562(b) Amdt. 6 is accepted as a means of compliance under the following conditions: (1) CS 27.562(b)(1) Amdt. 6 is accepted as a means of compliance, noting that the 30 g at seat attachment level was based upon the typical underfloor structure of a conventional rotorcraft. Therefore the 30 g is only valid if the structure underneath the seats has equal or better damping characteristics than a conventional rotorcraft. If specific design features are integrated, less than 30g at the seat may be acceptable based on analysis supported by tests (2) CS 27.562(b)(2) Amdt. 6 is accepted as a means of compliance with the following addition: For CTOL peak floor deceleration should occur in not more than 0.05 seconds after impact and should reach a minimum of 26 g. For CTOL seat/restraint systems not being in the first row, peak deceleration should occur in not more than 0.06 seconds after impact and should reach a minimum of 21 g. (3) CS 27.562(b)(3) Amdt. 6 is accepted as a means of compliance. (c) CS 27.562(c) Amdt. 6 is accepted as a means of compliance. (d) CS 27.562(d) Amdt. 6 is accepted as a means of compliance.
