There is a school of thought that would suggest that the Seneca is a more superior platform for the IR.
There is on doubt that the DA42 is far easier to operate compared to the PA34, and is ideal for weekend flyers with PPL/IRs.
So for those of you who are " an ace of the base " it is irrelevant what type you train on as you will simply sail through the course and test irrespective of type.
But for those very marginal people, you will succeed (just) on the DA42, but probably not on the PA34. It is not just having less levers to push and pull. You are demonstrating basic skills such as TRIMMING, and TRIMMING well. Other aspects are AIRMANSHIP and SITUATIONAL AWARENESS, not to mention CAPACITY.
So you decide to take the path of least resistance, obtain your licence with a MEP(land) endorsement and think YES, I have made it. Phew.
So the very marginal person now undertakes the MCC/JOC. Struggles and might even find it an overwhelming experience depending upon the complexity of the device. Just proving a bit too much? But MCC certificate issued.
Interview followed by a disappointing sim ride................need I say more.
The writing was probably on the wall at an early stage even before the twin engine flying started. You need a honest discussion with the training team before you spend your hard earned money in the first place.
PPL training is one thing.......proceeding to professional training is clearly a different matter.
