Controls
C. Effects on safety: possible delay in ground emergency egress
NOTE: During ground emergency egress, if pulling the MDC firing
handles fails to shatter the canopy, egress must be accomplished by
opening the canopy with the canopy control lever.
NOTE: If pulling the MDC firing handle fails to shatter the canopy and
ejection is necessary, the canopy penetrators will shatter the canopy
when ejection is initiated.
WARNING: Ejection with canopy in any position other than fully
closed and locked is not recommended. Serious bodily injury and
seat malfunction may occur.
