The pods enable the boom operator to refuel two planes at once. After the boom operator establishes contact with the aircraft's fuel tank, the computer takes over. Up to 1,100 gallons of fuel flow through the boom per minute and about 470 gallons per minute through the drogue.
Car manufacturers often suggest changing oil filters every other time you have your oil changed. Most parts and oil manufacturers, however, say to replace oil filters with every oil change, which should occur every 3,000 miles or three months (whichever comes first).
Consider how this applies to service intervals. If the manufacturer recommends an oil change every 10,000km, then an oil change every 8,000km would comply to the cheap insurance argument. Servicing only slightly more often doesnât cost much more. What about, once you decide to change the oil every 8,000km, you discover that itâs now only a small incremental price increase to change the oil every 6,000km.
