London to Nashville: the customs window sets the time
Farnborough to Nashville International is 3,618 nautical miles, 4,164 statute miles: about 600 nautical miles further than London to New York and a little short of London to Miami. A heavy or ultra-long-range jet flies it non-stop; a super-midsize such as the Challenger 350 stops once for fuel.
Nashville is six hours behind London for most of the year. Leave Farnborough at 1 pm and an ultra-long-range jet lands at Nashville International around 3.30 pm local time, fifteen minutes from Broadway, with the evening ahead.
That afternoon arrival is deliberate. US Customs and Border Protection inspects private arrivals at Nashville International from 3 pm to 9 pm Central Time, and the permission to land is secured before the aircraft leaves London. A morning departure from London would land before the officers start, so we plan the flight backwards from the customs window.
