1.   And the safety board called for an immediate campaign to educate pilots on new strategies for flying through icing conditions.

2.   As a result of the crash, the FAA ordered new procedures for operating all ATR models in icing conditions.

3.   But having a bigger data base on the performance of that kind of plane in icing conditions could have given stronger clues to the problem, experts say.

4.   Eric Lindros and Paul Kariya have led the charge recently, with Lindros blaming poor ice conditions for the recent increase in groin and abdominal injuries.

5.   In icing conditions, the pilots activate a system that continually expands and contracts the boots on the edges to keep ice from forming.

6.   In early December, the FAA banned the plane from flying in icing conditions.

7.   Neither Comair nor Embraer establishes a minimum safe maneuvering speed in icing conditions.

8.   The ATR that crashed was certified for flying in icing conditions, but not as severe as what the pilots encountered, investigators have concluded.

9.   The agency directive specifically prohibits the aircraft from flying when icing conditions are forecast or present.

10.   The new rules prohibit the use of autopilot during icing conditions, for example, and require minimum speed and power level in the engines of the ATR planes.
