PHI SONATA 2

The Sonata is an A-wing 

SONATA 2 TECHNICAL FEATURES

The SONATA 2 is not only the small sister of the SYMPHONIA 2. Because of the higher safety level it can afford a very big extended weight range to offer the pilot or the school more options. The covered lines make it easier for not so experienced pilots. The take off behavior as well as the roll stability are excellent: a MUST HAVE for a modern wing in that class.

The feedback from active schooling with the SONATA 2 is confirming, that we reached our goal: takeoff is very easy, roll stability excellent and most noticeable: the performance stands out from all others.

SONATA 2 DESIGNER’S NOTE

To optimize wings in that mid A class is not an easy task. The structural stiffness is a challenge. More wing curve is not the way to go as it results in less roll compensation. So we had to invest in the internals and the line angles. In contrast to the first generation of SONATA, the SONATA 2 has 3 main lines and plenty of diagonal fingers. A very high complexity for this cost critical class of “school wings”. But the result of this effort is opening the door for not only being a “school wing”. The SONATA 2 has a delightful handling and an outstanding performance, which pleasures advanced pilots long after their first flights on the training hill.
