Diamond anounced two day ago that the DA50 will come in two version: the DA50 SuperStar and the DA50 Magnum with the AustroEngine AE300 powerplant. This is not hot news, but what Diamond added is that the DA50 Magnum will be pressuzried !

Even if you’re not an IFR pilot, this probably makes it even more attractive. Pressurization means getting to higher altitudes without need for supplemental oxygen, and less ears problems. For IFR pilots, this makes a major difference.

The maximum altitudes we can use without pressurization are in the 10 to 12′000 feet range, and these are the worst place to fly: most of the icing layers are found below 15′000 feet. Getting a pressurized aircraft does not mean that you can fly in icing conditions, but if you encounter them, that will not be at cruising altitude, and clibming through is an option.

This is particularly enjoyable when descending is not possible beause of high grounds. Another advantage is the possibility to fly high-speed approaches (particularly as these planes will be damn quick) without having to sustain the rapidly chaning pressures, which can lead to sever ears trauma.

Apart from the Cessna P210, there are not a lot of pressurized single engine airplanes around. Piper offers a turbo Saratoga with built-in oxygen, but if you want a pressurized Piper, you’ll have to buy a Mirage or a Meridian, which is clearly not adressing the same market as the 210 or the DA50.

Once again, Diamond seemd to have heard what pilots are expecting: the decision to add pressurization is the direct outcome of requests from customers who booked a DA50. I must admit that if I had the money (the prices are not yet anounced…), that would probably be my aircraft of choice.
