I don't fly noise abatement departures at all in Africa because off the very high chance of birdstrike. I don't want to hit birds when I am 20 degrees nose high with all my focus on the artificial horizon, the ASI, and generally scanning in the cockpit. I want the aircraft in a sensible climbing attitude, accelerating sensibly, and I want to see the monitor birds, the herons, and the clouds of swifts etc so that I stand a chance of avoiding them. At 200 kts and climbing the way I do I have seen and been able to miss large birds on a number of occasions and when you are climbing out of Kinshasa and all thats beneath you is jungle and the Congo river you think carefully about how you are going to climb the plane.
I am sorry, I don't buy that either, although my profile says IE and HK, I am actually from Africa and you have more chance of being shot at in the Congo than hitting a bird, maybe you should re-evaluate your departure profile!!
I am just saying!!
