The aircraft at origin on the Varc graph. The graph is used to determine which Varc other aircraft are in relation to the target aircraft. The aircraft for which a Varc relative to the target aircraft is desired.
Unloaded dives are always shallow dive.
Carried FPs are used to determine flight angle. If the target aircraft is in vertical flight, always use the Varc, regardless of the Harc. Note that the left side of the Varc chart indicates the front of the target aircraft. To determine which Varc the attacking aircraft is in, locate the position of the attacking aircraft on the graph, then determine the pitch type of the target aircraft. Read the Varc from the Varc legend for that arc.
