Zaherk Posted May 26, 2014 Share Posted May 26, 2014 Was it a sudden snag, started overnight or got it worse over time? Do you start with Atm on or off? Do you always start the no 3 Engine first or do you alternate your starts? We start with our Atm on until about 15-30% and then disconnect the Atm for better bleed, especially in Goma and Bukavu with higher altitudes.
