What is descent in aviation?
A descent during air travel is any portion where an aircraft decreases altitude, and is the opposite of an ascent or climb.
How does an aircraft descend?
A plane descends when its wings produce less lift than it weighs.
What does descend at pilot’s discretion mean?
A phrase, when used in conjunction with altitude assignments, that means that ATC (air traffic control) has offered the pilot the option of starting to climb or descend whenever he or she wishes and conducting the climb or descent at a rate he or she desires.
What is the normal rate of descent for an airplane?
Idle descent in many jets is around 3,000 feet per minute until reaching 10,000 feet. There is a speed restriction of 250 knots below 10,000 feet, therefore the flight management computer will slow the aircraft to 250 knots and continue the descent at approximately 1,500 feet per minute.
How is aviation descent rate calculated?
If you multiply your descent angle (1 degree) by your miles-per-minute, then add two zeros to the end (x 100), you’ll have your FPM descent rate. So in this example, if you’re flying at 120 knots, you’re traveling 2 miles-per-minute (MPM) (120/60=2).
When should a pilot start descent?
As an example, if the airplane is flying at 30,000 feet the pilot should start the descent at 90 miles. Once the airplane is closer to the airport and the instrument landing system (ILS) can be used, the 3-degree descent is more finely tuned to touchdown.
What is the most dangerous part about flying?
Boeing research shows that takeoff and landing are statistically more dangerous than any other part of a flight. 49% of all fatal accidents happen during the final descent and landing phases of the average flight, while 14% of all fatal accidents happen during takeoff and initial climb.
What do pilots say when landing?
Thank you.” To indicate the landing clearance or final approach, the Captain will either make the following announcement and/or blink the No Smoking sign. “Flight attendants, prepare for landing please.” “Cabin crew, please take your seats for landing.”
How fast is plane going when it lands?
Q: How fast do airplanes go when landing? A: Commercial airplanes land at approximately 150 to 165 MPH.
How do pilots talk to ATC?
The most common form of communication in aviation, very high frequency (VHF) radio calls are what we use for around 95% of our communications with ATC. In simplified terms, the transmitting station sends a signal that travels in a straight line and is picked up by the receiving station.
What is the minimum safe altitude anywhere?
(c) Over other than congested areas – An altitude of 500 feet above the surface except over open water or sparsely populated areas. In that case, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure.
What is amended clearance?
A clearance issued by air traffic control amending a previous ATC (air traffic control) clearance in response to a request from the pilot or initiated by air traffic control to avoid conflict with other aircraft or severe weather.
What is a good descent rate?
“500 feet per minute is a good rate to work with. Generally, passengers will not be alarmed by a decent rate of 500 ft/min. At 120 knots which is two miles per minute (120 nautical miles per hour divided by 60 minutes = 2 miles per minute), you need to begin your descent 16 miles out.
Why do planes speed up before landing?
The aircraft flares just before touching down. It descends with a constant velocity, and just before touching down pulls the nose up to reduce the descent. Upon accelerating, the simulator pushes forward like the aircraft does, but also slowly rotates backwards so that the pilot feels sustained seat back pressure.
Why do planes fly at 35000 feet?
The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.
