Quick Reminder about
Schedule Pointe
The schedule change frequently due to maintenance, check rides, and other conflicts. To avoid missing a scheduled appointment CHECK THE SCHEDULE EACH NIGHT FOR THE FOLLOWING DAY TO CONFIRM FLIGHTS, GROUNDS, AND TIMES.
Aerodynamics
The previous newsletter talked about the basic aerodynamics acting on the airfoil.
This newsletter will talk about Effective Translational Lift (ETL). Next newsletter will talk about Transverse Flow Effect
Accelerating from hovering flight into forward flight the induced airflow over the rotors decreases and becomes more horizontal(translational lift), this is because as the helicopter moves forwards it creates a horizontal wind which lowers the relative wind and increases AoA.
When translational lift covers the entire rotor system that is when we call in "Effective" translational lift.
Note: Any amount of airflow moving horizontally into the rotors will increase lift, the most noticeable point is at ETL. As the helicopter accelerates faster than ETL the airflow is even more horizontal and further increases lift.
Commercial Question
Someone calls you asking if he can pay you to fly him to the Columbia river to take photos of some wind surfers.
The flight will depart BDN and fly north to the river(about 80NM away) and return the same day to BDN.
Can a commercial rated pilot accept payment for this job?
Ask these questions to figure it out: "Can a commercial certificated pilot do this?"
Is this flight on the commercial certificate alone or with a company?
If Alone, is the job listed in part 119?
If Yes,
If common carriage is Not involved, then can be done, just make sure you comply with and other limitations listed in part 119
If common carriage is involved, then cannot do it.
If No, then most likely cannot be done.... Unless It can be considered a "Private carriage" flight.
If Company, is the company, pilot, and helicopter certified for the operation? (EX. an agriculture part 137 job needs an 137 operator, 137 helicopter, and 137 check out pilot)
If yes, then can do.
If No, then must get rated to do the job.
If ever common carriage is involved, then the job needs to be done under part 135 or part 121.
Answer: I'll post the answer on the next newsletter.

And this is the sublink that goes to and miscellaneous page with some really good information about the helicopter and components that aren't identified on the preflight check list.
