It was pointed out that the previously announced motor impulse limits were in conflict with NFPA 1127 when it came to complex flights. Therefore the amended motor impulse limits for LDRS 33 are :

Non-Complex flights - Total motor impulse must be less than 20,480 Ns ( < "O" motor)

Complex flights -- Total combined motor impulse must be less that 10,240 Ns. ( < "N" motor)

The LDRS web page has a type error on it. It lists 20,480 Ns as the restricted limit for both complex and non-complex flights. The letters are correct the numbers are wrong. Thought you may want to know so it can be fixed.
