Rotorcraft Picketing / lashing equipment safety factor
Rotorcraft Picketing / lashing equipment safety factor
(OP)
Dear Sir
Helicopter tiedown in wind speeds of up to 80kts (on land only). Ref. Defstan 970 (part 308/309). Safety factors for attachment points and structure are 1.25 and 1.5 respectively.
WHAT SAFETY FACTOR is required for the lashings / cable equipment? Can you ID a spec?
Generally we use a factor of between 3 or 6 when personnel safety is involved.
Regards
Che Smit
