35 x 3=105. This means you should begin your descent 105 nautical miles from your destination, maintaining a speed of 250 KIAS (about 45 percent N1) and a descent rate of 1,500 to 2,000 feet per minute, with thrust set at idle.

Usually a large aircraft like the Boeing 747 will use two things to slow down. It not only uses the wheels, which have brakes, but it also has reverse thrusters. The reverse thrusters are essentially the force from the engines directed backwards (thus the reverse part).
In aviation, the rule of three or 3:1 rule of descent is a rule of thumb that 3 nautical miles (5.6 km) of travel should be allowed for every 1,000 feet (300 m) of descent. For example, a descent from flight level 350 would require approximately 35x3=105 nautical miles.
If the plane doesn't crash, the descent rate generally can't hurt you. If the plane crashes, the horizontal deceleration is likely to do far more harm than the vertical deceleration. That said, 18,000 feet per minute is pretty fast, like 180 knots, so unpressurized it could cause possibly ear & sinus damage.
What speed does a Boeing 747 land at? A 747 'Jumbo Jet' would typically land at a speed of about 145kts-150kts (166mph-172mph), depending on the landing flap setting selected.
Daily. An airline transport pilot can fly up to 8 hours per 24 hour period and up to 10 hours if a second pilot is aboard. Pilots are required to rest a minimum of 16 hours postflight.
Full throttle may sometimes be needed for takeoff or a go-around, but not in normal flight. Likewise, one of the few times an automobile may need full throttle is when merging onto a high speed highway with speedier traffic.
Pilots are trained to handle all sorts of nerve-racking situations, but that doesn't mean that they don't get scared—especially in these real instances, told by the pilots who experienced them, of serious in-flight fear.
The idea is to get as much altitude as possible, as close to the airport as possible. So you have a relatively steep initial climb, followed by a reduction of climb angle to cruise climb and a power reduction.
Crashes that destroy the airframe are the most obvious answer, but minor, low-speed incidents on the ground can also bring a plane's career to an end. This was the case for a SaudiaBoeing 747-300, which taxied into a ditch in Kuala Lumpur in 2001.
A Boeing 747-8 landing with 85% of its payload and 30% of its fuel, weighs 92% (8F) or 98% (8i) of its Maximum Landing Weight (MLW). The FAA/EASA Minimum runway length requirements for MLW landings are 7,500ft (~2,300m) for the 747-8F, and 6,750ft (~2,000m) for the 747-8i.
Question: Right after takeoff, it often seems that the pilot slows down and the plane drops somewhat. Why is that? I have noticed that it is pretty consistent. Answer: The sensation of slowing down is really one of slowing the rate of acceleration; this is due to reducing the thrust after takeoff to the climb setting.
All airplanes will be exposed to drag during flight. They must overcome this aerodynamic force to achieve and maintain lift. Otherwise, airplanes would essentially fall out of the sky. Air brakes are control surfaces that increase drag so that airplanes slow down during flight.
The first indication to passengers that a plane is descending is the reduction in engine power, but that might not mean the aircraft is slowing. The most comfortable and quiet way for pilots to reduce the speed of a plane during the stages of descent is to level off briefly.
