A twin with a failure on the back-up and with the second engine running struggles to get back to the pad. How on earth could a single do it with negative airspeed.
If you are taking off over a built-up area in a single, that's where you are going if the engine fails.
Obviously, but if you fly a Cat A departure profile in a single,assuming no engine failure and you don't back out beyond the perimeter, you will be departing the pad area with translational lift, much better than leaving the pad at below translational speed with a towering take off.
That's the rationale behind why I would do it anyway.
Is it any more dangerous to fly out this way?
