The eight ways to slow a jet
When you're driving your 5-speed manual transmission car and you exit an offramp, besides just taking your foot off the gas pedal, there are a couple of different ways that you can slow down. Most people probably put on the brakes, but you could also downshift as well.
In an airliner, there are four different ways inflight and four methods on the ground to slow a jet, and often these techniques can be used in conjunction.
Unlike turboprop airplanes, jets are rather difficult to slow down and require a bit of planning in advance to avoid burning too much fuel or ending up too high at the airport for landing.
So let's start with our Boeing that's at 33,000 feet. Pilots will use a rough "3 to 1" guide when deciding when they'll need to start down, adjusting for wind as needed.
To do that, take the 33,000 feet, drop the zeros and multiply it by three. 33 X 3 = 99 miles.
