We utilize on-board aircraft radiation dosimeter data acquired during the major solar-terrestrial disturbances of October/November 2003 to demonstrate these effects along with the increased dose due to the ground-level event of 29 October 2003 on a mid-latitude flight path.
For 169 of these events, we estimated effective and equivalent dose rates and doses of galactic cosmic radiation (GCR) and solar cosmic radiation (SCR), received by aircraft occupants on simulated high-latitude flights.
When a stratospheric satellite travels by prevailing winds in the stratosphere, its cross-track displacement needs to be controlled to keep a constant latitude orbital flight.
However, latitude dispersion grows with flight duration, and trajectory dispersion growth is significant from 30- to 100-day flights.
Figure 1 shows the number of profiles obtained in each of the five latitude bands for each flight series.
A witness at the hearing, Hank Krakowski, a United Airlines vice president for corporate safety, said the airline had chosen lower altitudes and latitudes for several flights from the United States to Asia in the last few days to avoid communications problems and possible health effects.
With that in mind, the courts have given flight crews wide latitude, even when a review suggests the airline employees erred in removing a passenger.
The measurements contain records of flight time and aircraft latitude, longitude, and altitude.
Then it's on to the Thiel Mountains to refuel, with a final flight to 89 degrees latitude, where participants begin a 69-mile trek to the South Pole on cross-country skis.
For every flight, geographical longitude and latitude were logged by the devices at 1 Hz (i-gotU GT-120 Phototrackers, Mobile Action Technology, Inc., Taiwan; approx. 15 g).
Distribution covers all longitudes and latitudes of STS-91 Space Shuttle flight trajectory to Mir Space Station.
