13.6 Health effects. There are no regulatory limits for crew or passenger doses in the United States. However, by way of comparison, the annual dose received by a crewmember from cosmic radiation is several times greater than what a

member of the general public is allowed from manmade sources. Pregnant crew members should avoid flying polar routes.

13.7 Conclusion
Airplane crews flying exclusively on polar routes will receive a radiation dose similar to those experienced by crews flying routes such as Athens to New York. The cosmic radiation dose will be about one-third of the average annual maximum dose established for radiation workers by ICRP and does not pose a significant health risk.
While no practical means exist to limit cosmic radiation levels during flight on board airplanes, airlines should develop operational procedure for addressing the infrequent solar flare that can significantly increase radiation levels. Special precautions should also be in place to limit radiation doses for pregnant crewmembers.

CHAPTER 14 TRAINING REQUIREMENTS PAGE 14-1
14. Training Requirements :
The training program at Air India would cover the following issues.
1. QFE/QNH (airport altitude settings)[See AC 91-70, Oceanic Operations] and meter/feet issues for flight crew and dispatcher training. See Advisory Circular (AC) 120-29, Criteria for Approving Category I and Category II Landing Minima for FAR 121 Operators, as amended, for information in regards to cold temperature effects on altimeters.
2. Fuel freeze strategy and monitoring requirements. Maintenance, dispatch, and flight crew training.
3. General route-specific training on weather patterns and aircraft system limitations.
