# How do you find the slope of a glide?

## How do you find the slope of a glide?

Distance (20) divided by Altitude (10) = 2/1 = Glide Ratio of 2.0 The glider flew forward two feet for every one-foot drop in altitude. Distance = 100 ft. Altitude = 10 ft. 100 divided by 10 = 10/1 = Glide Ratio of 10.0 Page 2 The glider flew forward 10 feet for every one-foot drop in altitude!

What does a 3-degree glide slope mean?

300 feet per nautical mile
The rule simply states that a conventional, 3-degree glideslope (normally the optimum vertical profile to use during a landing approach) descends 300 feet per nautical mile. In other words, multiply your distance from touchdown by 300 feet to determine target altitudes while on final approach.

### What will be the rate of descent when flying down a 12% glide slope at a ground speed of 540 knots?

1) Speed x % Gradient = 540 x 12 = 6480. What is the minimum rate of descent required? Height to loose 27000 feet in 15 minutes or 27000/15 = 1800 feet per minute.

How tall can you be on a 3 degree glideslope?

A better judge for height on a 3 degree glideslope would be to use 300ft per nautical mile. The 1 in 60 rule is only an approximation and is of no real use for angles of more than 25 degrees. 300′ / nm is the result you get using the 1:60 rule.

#### When to use the 1 in 60 rule?

A better judge for height on a 3 degree glideslope would be to use 300ft per nautical mile. The 1 in 60 rule is only an approximation and is of no real use for angles of more than 25 degrees. 300′ / nm is the result you get using the 1:60 rule. My earlier comment that it should be 2000′ was bollocks.

How does the 60 : 1 rule help you plan a perfect descent?

Step 3: To finish things off we’ll take the altitude we need to lose (5,000′), and divide it by the minutes to the fix (5). 5,000 feet / 5 minutes = 1,000 FPM. We’ll need to descend at 1,000 FPM to make the crossing restriction.

## What’s the rule of 1 mile off track?

Basically the rule is that for every 60 miles travelled, 1 mile off track is equal to a track error of 1 degree. (eg if you have departed from point A and your planned track is 360 degrees, and at point B which is 60 miles from dep. you find yourself 1 mile right of track, your actual track has been 001 degrees.)
