NOTE 1: AECTP 100-4 Distances provided as examples only. The most current AECTP 100 values should
be applied.

810 values should be applied.
A.1-3.1.2.3.1 Fixed Wing Turboprop Aircraft Vibration (Appendix C, Annex 2, Paragraph C.2-
4.1.1).
The most common propeller cargo aircraft used throughout NATO is the C130, of which the four
and six bladed propeller variants are most typical (4-blade, f0=68 Hz and 6-blade, f0=102 Hz). The
vibration severities for these aircraft are defined in MIL-STD-810, Method 514, Annex C, for
`Propeller Aircraft'. If other cargo aircraft are identified as part of the LCEP, then the blade
frequencies (f0) for these shall also require consideration. Since it is not always possible to
predetermine the specific aircraft types that will be used during transportation, the total test
duration based on the total flight duration defined in AECTP 100, Annex E, Appendix 1 for each
commodity type transported by `Propeller Aircraft' should be split between the different blade
frequencies (f0) identified. For C130, this will require the test to be divided equally between the
two blade frequencies (f0 = 68 Hz and 102 Hz) as a minimum.
A.1-3.1.2.3.2 Fixed Wing Jet Aircraft Vibration (Appendix C, Annex 2, Paragraph C.2-4.1.2).
The vibration environment associated with cruise is largely addressed by other vibration
environments within the LCEP and need not necessarily be tested. The take-off vibration
environment is significantly more severe than that for cruise, and can be addressed by the vibration
profiles in MIL-STD-810, Method 514, Annex C for `Jet Aircraft Cargo'. The duration of this test
