samauri,
Why do WSOp CMM and Linguists need a 20 hour dominie package?
The short answer is that they don't. However, a flying package is an integral part of any course of initial aircrew training.
There are many benefits of a flying package(demonstration of skills taught, capacity, airmanship and SA to name but a few) and the final product is far superior to those who did not have the opportunity to undertake an applied phase. Proof of this comes directly from the next units in the training system(OCU's,DHFTS), who comment that the current students are more capable that their predecessors. Further proof comes from students who feel better prepared for the rigours of conversion training.
On a lighter note how did you get on with your Dominie package?
ALWAYS assume NEVER check
