But many pilots choose to make a U-turn instead, several pilots said yesterday.

The pilot might choose another route; he'd want to cover as much ground as possible.

The pilot could choose between wheel or stick control based on his preference.

Based on their performance ranking, the pilots then choose among more specific career paths.

Barring any definite reason to go below a plane, pilots almost always chose to go above.

If it is not in what circumstances can a pilot chose to deviate from the flight path and how will the system cope with this?

The pilots could have chosen a different route.

No pilot would have intentionally chosen this place to put down, except in the case of a crisis.

Positioning system navigation allows pilots to choose their own routes.

If lift is not found during a cross-country flight, for example because of deteriorating weather, the pilot must choose a location to "land out".
