REFLECTOR: Main Gear Emergency Extension

[Alex Balic]

Maybe even 6 seconds seems like a really long time when you are flying a
glider on final............ :)

My experience of dropping the gear using the dump valve is the same as 
Ron's.  The mains come down in about 6 seconds, followed a couple 
seconds later by the nose gear.

I've done this on the ground and in the air with no noticeable 
difference in time.
