Nope, I'm not saying that at all. I am referring to legacy aircraft.
The OP did ask.....
He didn't ask about a legacy aircraft, the PA44 is still in production.
One of the essential rules when buying a twin is that it must be capable of a positive rate of climb with the critical engine failed at MTOW at the highest density altitude you are likely to encounter. In South Africa (for example) that means 14000 feet.
This is a bit of a silly statement. How many twins or even single piston aircraft could do this. There's probably quite a few turbine aircraft that would struggle at 14,000' single engine.
There are times when you have to either not go there or wait for a time of the day that gives a more friendly density altitude.
