1 Monitor EGT during start to prevent an EGT
exceedance. Autostart allows EGT to exceed the
in-flight start limit.
2 Engine may accelerate to idle very slowly,
especially at high altitudes.
3 Slow acceleration may be incorrectly interpreted as
a hung start or engine malfunction. If N3 is steadily
increasing and EGT remains within limits, the start
is progressing normally. Any further cycling of the
fuel control switches will result in longer start
times.
