2.1 Introduction
Section 2 includes operating limitations, instrument markings and basic placards necessary for safe
operation of the LS8-18 sailplane, its standard systems and standard equipment.
The limitations included in this section and in section 9 have been approved by LBA (Luftfahrt-
Bundesamt Braunschweig).
The LS 8-18 sailplane has been designed and approved according to JAR 22 requirements. Factors
of safety (relation of ultimate loads to permissible maximum loads occurring during operation) are
1.5 only. Thus, ultimate loads will be reached, when exceeding permissible load factors by 50%.
When exceeding permissible speeds, the safety reserve is much lower.
Maximum loads should never be caused by the pilots control surface deflections – they result from
severe turbulence and the necessary control surface deflections to retain the desired flight attitude.
Severe turbulence
according to airworthiness requirements includes wave rotors, cumulonimbus
clouds, dust devils and turbulence when crossing mountain ridges in strong winds.
Warning: Therefore, operational limits, - speeds and load factors - must be adhered to !
