# Question: Aviation How To Initate A Descent?

## How do pilots know when to descend?

Question: How do pilots know when to descend to land on the assigned runway at the correct speed? Answer: Pilots plan the descent based on the wind and air traffic flow. Working in partnership with air traffic control, the descent is executed allowing adequate distance to descend and line up with the proper runway.

## How does an aircraft descend?

A plane descends when its wings produce less lift than it weighs.

## What is the 3 1 rule in aviation?

In aviation, the rule of three or ” 3:1 rule of descent” is that 3 nautical miles (5.6 km) of travel should be allowed for every 1,000 feet (300 m) of descent.

## How do you calculate descent in aviation?

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).

## How cold is it at 35000 feet?

How cold is it up there? The higher you get, the colder it gets, up until 40,000 feet. If the temperature at ground level was 20C, at 40,000 feet it would be -57C. At 35,000 feet the air temperature is about -54C.

## How fast do airlines descend?

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.

## 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 do pilots know where they are?

Primarily, the “ILS,” as it is commonly known, consists of two radio beams emitted from transmitters right next to the runway. All pilots have to do is follow the beams down to 200 feet above the ground, at which point they must be able to see the runway and its approach lights.

## How do you find the descent point?

A quick and easy way to figure it out is to start with your altitude above field elevation and multiply that number by three. This will give you the approximate distance in nautical miles from the airport to start a 500-foot-per-minute descent in the typical light general aviation airplane and reach pattern altitude.

## How do you calculate aircraft drift?

A 1 degree offset angle at 60 nm equates to 1 nm of displacement.

1. Distance off track = (number of degrees off course x distance to station)/60.
2. Maximum drift angle (Max Drift ) = Windspeed divided by Groundspeed in miles per minute.
3. Slant Range Overhead DME = Altitude in feet/6000.

## What is the 3 6 rule?

The 3 – 6 – 3 rule describes how bankers would supposedly give 3 % interest on their depositors’ accounts, lend the depositors money at 6 % interest, and then be playing golf by 3 p.m. In the 1950s, 1960s, and 1970s, a huge part of a bank’s business was lending out money at a higher interest rate than what it was paying out

## What is Glide in aviation?

Description. The Glide ratio of an aircraft is the distance of forward travel divided by the altitude lost in that distance. The glide ratio is affected by all of the four fundamental forces that act on an aircraft in flight – lift, drag, weight and thrust.

## What is descent rate?

Rate of descent is the vertical component of the aircraft’s velocity, normally expressed in feet per minute. This speed increases with aircraft mass. When heavier, the aircraft is expected to fly at higher speed during the descent and initial approach phase.
