Rule 508.06
Quote:
Screen flanges should be a minimum of 50 mm and should be fastened every 100 mm if using “bobbins”; it is recommended to use metal “bobbins” with heads, as opposed to the recessed plastic type.
|
Can anyone clarify this rule. Does it mean screens can only be affixed every 100mm, or that fixings should be at most 100mm apart but closer than 100mm is OK?

I'd say it means it's gotta be fastened at least every 100mm.

fixed every 100mm uim rule book poage 132 gives a better disc
5.
It is strongly recommended that the transparent areas shall be built
of 12 mm thickness polycarbonate or stronger. The transparent
areas shall be attached by internal flanges that overlap by at least
50 mm. If attached by bolts, they shall be at least 6 mm diameter
high strength bolts spaced not greater than 100 mm apart and
properly installed with bushing to protect against thermal expansion
stresses. The loads of the bolts on the outside of the transparencies
shall be distributed and transferred via external flanges at least 50
mm wide and completely surrounding the transparencies. It is
recommended that the external flanges also overlap the structure
by at least 50 mm and be bolted or bonded to the structure. If the
transparencies are bonded to the cockpit structure, the primary
supporting flanges shall be internal and overlapping by at least 50
mm completely surrounding the transparencies. External flanges
are also recommended to strengthen the bonded attachment.

Yeh, but that is the guideline, not the rule (so I admit I hadn't read it DOH)
