Document Title: Airmen Transition to Experimental Airplanes
Summary: This revision of AC 90-109 adds increased emphasis on loss of control issues when transitioning to unfamiliar aircraft. New text focuses on transitioning to other type-certificated aircraft, instead of just experimental aircraft. We added emphasis on awareness of differences in aircraft equipment, suc as advanced avionics and complex equipment like retractable landing gear. We added text identifying the availability of General Aviation Manufacturers Association (GAMA) Publication 5, which provides master syllabi for transition training. Lastly, we made updates to safety data and made editorial and style corrections.

Document Title: AC 00-45G CHG 2, Aviation Weather Service Program
Summary: This AC provides new information that will benefit all pilots and operators using the public internet access weather from a third party vendor. With increased access to these weather products via the public Internet, the aviation community has access to an over whelming amount of weather information and data that will support self-briefing. This AC describes the weather products distributed by the NWS.

Section 1 provides updates to civilian agencies names and services to the aviation community

Section 2 eliminates the terms Primary and Supplemental and adds additional guidance on public internet weather briefings

Section 9 updates criteria and collaboration for the Collaborative Convective Forecast Product; revises the Extended Convective Forecast Product (ECFP), National Convective Weather Forecast (NCWF), Current Icing Products (CIP), Forecast Icing Products (FIP), and Graphical Turbulence Guidance (GTG2); and provides new guidance for Ceiling and Visibility (C&V).

Document Title: AC 120-35D, Flightcrew Member Line Operational Simulations: Line Oriented Flight Training, Special Purpose Operational Training, Line Operational Evaluation
Summary: This advisory circular (AC) presents guidelines for the design and implementation of line operational simulations (LOS), including line-oriented flight training (LOFT), special purpose operational training (SPOT), and line operational evaluation (LOE) for flightcrew members. This document does not interpret the regulations; interpretations are issued only under established agency guidelines. As operators develop LOS, they should develop an interdependent relationship between their Human Factors, crew resource management (CRM), flight operations, and safety initiatives since they are linked to a common safety goal.

Document Title: AC 90-APP, Additional Pilot Program for Phase I Flight Test
Summary: This advisory circular (AC) provides information and guidance on the Additional Pilot Program (APP) for flight testing experimental aircraft. The APP was developed to improve safety by enhancing Builder/Owner Pilot (BP) skills and mitigate risks associated with phase I flight testing of aircraft built from commercially-produced kits through the use of a qualified additional pilot and powerplant testing. The APP is an optional program, which provides another pathway to conducting Phase I flight testing.
