| appearance as argument number 1 |
|
|
| (instance TripFn UnaryFunction) | Transportation.kif 1727-1727 | Trip is an instance of unary function |
| (domain TripFn 1 Vehicle) | Transportation.kif 1728-1728 | The number 1 argument of trip is an instance of vehicle |
| (rangeSubclass TripFn Transportation) | Transportation.kif 1729-1729 | The values returned by trip are subclasses of transportation |
| (documentation TripFn EnglishLanguage "(TripFn ?VEHICLE) denotes the subclass of Transportation events in which a particular TransportationDevice ?VEHICLE is the vehicle. Contrast this function with TransportationFn, which is used to denote transportation events by a specific kind of vehicle.") | Transportation.kif 1730-1734 | The values returned by trip are subclasses of transportation |

| (=> (and (instance ?VEHICLE TransportationDevice) (instance ?TRIP (TripFn ?VEHICLE))) (instrument ?TRIP ?VEHICLE)) |
Transportation.kif 1736-1740 | If X is an instance of transportation device and Y is an instance of the trip of X, then X is an instrument for Y |

Transportation.kif 3711-3717 | If X long ton(s) is a navigable for shipping tonnage of Y, Z is an instance of water vehicle, W long ton(s) is a vessel displacement of Z, and W is less than or equal to X, then Y is capable of doing the trip of Z as a path |

Transportation.kif 3727-3732 | If X meter(s) is a navigable for draft of Y, Z meter(s) is a laden draft of W, and X is greater than Z, then Y is capable of doing the trip of W as a path |
| (=> (and (navigableForDraft ?WATERWAY (MeasureFn ?AMOUNT Meter)) (ladenDraft ?SHIP (MeasureFn ?DRAFT Meter)) (lessThanOrEqualTo ?AMOUNT ?DRAFT)) (not (capability (TripFn ?SHIP) path ?WATERWAY))) |
Transportation.kif 3734-3739 | If X meter(s) is a navigable for draft of Y, Z meter(s) is a laden draft of W, and X is less than or equal to Z, then Y is not capable of doing the trip of W as a path |
