Turn off your BlackBerry device when on an aircraft. Using
your BlackBerry device on an aircraft might affect aircraft
instrumentation, communication and performance; might
disrupt the network; might otherwise be dangerous to the
operation of the aircraft, its crew and its passengers; and
might be illegal.
BlackBerry devices are not inherently safe and cannot be
used in the presence of explosive fumes, explosive dust or
other explosive chemicals. Sparks in such areas could cause
an explosion or fire resulting in serious injury, death or
damage to property.
