How far is Darwin from Katherine? Here's the quick answer if you are able to make this entire trip by car without stopping.
Nonstop drive: 197 miles or 317 km
Driving time: 3 hours, 18 minutes
Realistically, you'll probably want to add a buffer for rest stops, gas, or food along the way. To get a better idea of how long this trip would really be, scroll down to calculate how many hours it would take if you drive with stops.
Now let's assume you have a private jet and you can fly in the fastest possible straight line between Katherine, Northern Territory and Darwin, Northern Territory. Because of the curvature of the Earth, the shortest distance is actually the "great circle" distance, or "as the crow flies" which is calculated using an iterative Vincenty formula.
Flight distance: 168 miles or 270 km
Flight time: 50 minutes
The straight line flight distance is 29 miles less than driving on roads, which means the driving distance is roughly 1.2x of the flight distance.
Your plane flies much faster than a car, so the flight time is about 1/4th of the time it would take to drive.
This is a relatively short flight in a private plane, but you might be planning to book a commercial flight. In that case, your travel time would really need to include how many minutes to get to your local airport, wait for security, board and taxi on the runway, land at the other airport, and get to your destination.
