You might wonder what makes your aircraft reach the top rankings when searching for Empty Legs. In this article, we'll describe how things work without going too deep into the mathematics.
Nautical Miles difference
When displaying the results of available aircraft with an empty leg, the system first calculates the difference between the distance for the empty leg and the distance required for the requested flight. It also adds any positioning needed to complete the empty leg and rank in order of the smallest difference.
So let's make an example:
Requested flight: VNY to SFO = 278nm
Empty leg #1: VNY to HWD = 271nm
Empty leg #2: VNY to APC = 302nm
Empty leg #1 needs to reposition from SFO to HWD for an extra 12nm, making a total of 290nm.
Empty leg #2 needs to reposition from SFO to APC for an extra 36nm, making a total of 314nm.
Since we rank based on the smallest difference from the original flight, we need to calculate the additional nautical mile that is requested.
Empty leg #1: 290nm - 271nm = 19nm
Empty leg #2: 314nm - 302nm = 12nm
This indicates that Empty leg #2 will be prioritized over Empty leg #1, even if the total Nautical miles are longer.
Aircraft Efficiency
It's not just about calculating the nautical miles between two destinations; we also need to consider the efficiency of the aircraft. Our systems calculate a variety of factors to determine how efficient it would be for the aircraft to deviate from the original flight in order to complete the requested empty leg.
This is where it becomes challenging to avoid getting too deep into the code and mathematics of our system. If the requested trip is below the threshold for the empty leg, the system will display the aircraft as available. However, if the trip exceeds the threshold, the aircraft will not be shown.
