Ground Start Ignition
The ground start ignition is integrated with the
engine start system from initiation of start to
the termination of start at 55% N
Either ignition A or ignition B, or both, may
be armed for operation during a ground start
cycle. It is recommended, however, that only
one ignition circuit be armed to prolong igni-
tion plug life.
Control and Indication
Ignition control and indication is provided on
the start and ignition control panel (Figure 7-
8) located on the overhead panel. Two split-
legend switchlights are used to arm A and/or
B ignition circuits for ground starting. Pushing
either switchlight will illuminate the legend
IGN A or IGN B. This indicates that the se-
lected system is armed to its associated engine
START switchlight (Figure 7-8).
Pushing a START switchlight will illuminate
the green START legend and, simultaneously,
the white ON legend of the selected ignition
switchlight, indicating that power is being ap-
plied to the selected ignition exciter. Ignition

will continue until the start cycle is termi-
nated. Ignition and start termination will be in-
dicated when the ignition ON light and the
START light extinguish.
Ignition and start may be terminated at any
time prior to 55% N
priate STOP switchlight.
In-flight Ignition
In-flight ignition is separate for each engine. It
is designed to provide dual ignition for wind-
milling relights or during single-engine operation.
Control and Indication
The in-flight ignition system is controlled by
a switchlight (Figure 7-8) for each engine la-
beled "IN FLIGHT START."
Pushing in one of these switchlights will il-
luminate the green IN FLIGHT START legend
as well as the white ON legend of both igni-
tion arming switchlights, completing the cir-
cuit for operation of ignition A and ignition
B for the associated engine. It is not necessary
to arm the ignition A or ignition B systems
prior to selecting in-flight start ignition.
Continuous Ignition
and Indication
Continuous ignition is primarily used as an
anti-flameout ignition. When selected, it pow-
ers one ignition exciter continuously on both
engines. The system is activated by a single
switchlight (Figure 7-8) labeled "CONT IGN"
only if either ignition A and/or ignition B has
been armed. The green CONT IGN legend,
the green IGN legend, and the white ON leg-
ends of the selected ignition system will all il-
luminate during operation of the continuous
ignition system.
Automatic (Stall Protection)
Ignition
The automatic or stall protection ignition sys-
tem provides anti-flameout protection during
periods of engine inlet turbulence caused by
high angles of attack.
