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.
Control
The automatic ignition system is controlled by
the stall protection computer using inputs
from the angle-of-attack vanes. The stall pro-
tection computer will initiate ignition A and
ignition B for both engines 3% before the
onset of the stick shaker and maintain ignition
operation until the angle of attack is reduced.
Indication
When the stall protection ignition is operat-
ing or during a stall protection system test, the
white IGN A ON and IGN B ON (Figure 7-8)
lights will be illuminated.
Power Sources
AC power at 115 volts and 400 Hertz is used for
the ignition system. Left and right engine igni-
tion A is supplied from the essential AC bus.
Left and right engine ignition B is supplied
from the battery bus through a static inverter.
Operation
Figure 7-9 is simplified schematic of the ig-
nition system used on the Canadair Challenger
CL-601-3R.
