Procedure for flying a Flashlight array
The following notes describe the procedure for flying left and right Flashlight arrays
designed to provide coverage of an outdoor area for approximately 15,000 people. The
configuration in this example is a six-wide Flashlight array, each side of the PA giving a
horizontal coverage angle of about 90
°
. This is made up of a 4-wide main bar assembly and a
twin bar assembly, requiring three lifting points. A half spacer bar connects the main bar and
twin bar, effectively continuing the curve of the array and setting the distance of the last two
columns, and hence the third lifting point.
1. Remove the flybars from the fly bar trunk
and set them out on the stage wings
according to the required configuration.
Splay all the bars out to form a smooth,
shallow curve by locating the spring-
loaded index pins on each bar in the bar
locator holes. Normally you will want to
start with all the index pins in the fourth
index hole, giving a horizontal splay angle
of 15 degrees between each vertical
column.
2. Move the flybars into the approximate position on the stage wing where the PA is to be
flown, and check that the curve of the array is going give you the expected horizontal
coverage. Position the bars such that the break between the first and second on-stage
columns is pointing directly at the mix position – this works best when the mix position
is between 27.5m (90ft) and 43m (140ft)
from the stage – and make sure that the
off-stage column is giving you adequate
coverage of the bleachers or side-stage
seating. Sometimes you may want to
open up the angle of the two off-stage
columns to the next (fifth) index hole to
give a little more coverage of the off-
stage seating if it is particularly wide.
Once you are happy with the splay of the
bars, choose and fix your flypoints such that the chain drops fall exactly above, and in
line with, the pick up points on the flybar. Note:

Note: the outer holes on the flybar are the
pickup points; the inner holes are the safety points. Take time to get the flypoints
positioned accurately, as it is much easier to do it now than later when the flybar is
under load.
