Using the Cannon Funnel
In the event that the radar and EOS are unavailable or you are unable to achieve a
lock, you can use the funnel display to manually aim the guns. The funnel appears
whenever you enable the cannon (by pressing C) without having first acquired a
lock. The funnel is designed to indicate the required amount of lead angle when
firing at a fighter-sized target 200 m to 800 m away.
The funnel consists of two curved lines. The distance between the two lines
represents a width of 15 m (the approximate wingspan of many fighter-sized
targets) at varying ranges from 200 m (top of the funnel) to 800 m (bottom of the
funnel). To use the funnel, bank your aircraft until the horizontal line in the middle is
parallel to the target’s wings (indicating you are in the same plane of maneuver as
the target). Pull lead until the wingtips of the target just touch the two outer
edges of the funnel. The further away the target is, the smaller its wingspan
appears, so the further down the funnel you place it, thereby increasing the
amount of lead you’re pulling. Rounds fired now will impact the target.
The Gunnery Funnel
What happens if the target’s wingspan is greater than (or less than) 15 m? The
funnel specifically represents a wingspan of 15 m; against larger or smaller
targets you’ll have to estimate the difference. For example, a large target like a
Tu-95 has a wingspan of roughly 50 m and will overlap the funnel. This figure
compares an Su-27 and a Tu-95 700 m away:
Comparing Target Wingspans with the Targeting Funnel
The following table shows the wingspans (minimum and maximum for variablegeometry
aircraft) that you’re likely to encounter. When engaging a target smaller
or larger than 15 m, remember to adjust the funnel accordingly. If the target is
smaller, don’t pull as much lead. If the target is larger, pull more lead than
indicated by the funnel.
