Backpacker
I agree with what you are saying. I am lucky because I have flown other peoples twins for them and numerous types so my currency is good and I have over 2000 hrs in Seneca Fives alone.
Not so guys who are paying for their time or aircraft and who can only afford a few hours a year.
Having said that how many twin pilots low or high time actually practice single engine work other than with an examiner?
The twin gives more options and with those more options the option to get it badly wrong as going up with one engine is a minimal climb experience which requires accuracy and an ability to manage energy and drag and definately to think out of the box.
