How do you find a runway heading?
Runway headings always come in pairs due to the fact there are two ends to a runway. They are separated by 180 degrees. For example: if there is a runway with the runway heading of 270 on one end the opposite end would have a runway heading of 090.
How do I find a runway in use?
If you have your sectional out, lay your pen or ruler on it to show the wind direction. See which runway alignment is closest to the ruler. That's the runway you want. Count on your fingers.Dec 18, 2013
How is runway designation calculated?
Runway numbers are determined by rounding the compass bearing of one runway end to the nearest 10 degrees and truncating the last digit, meaning runways are numbered from 1 to 36—as per the diagram below. The opposite end of the runway always differs by 180 degrees, so it's numbered 18 higher or lower.
How is runway length determined?
Runway Length
To determine the length of a runway, several factors are considered, including airport elevation, temperature, wind velocity, aircraft operating weights, take-off and landing flap settings and runway surface condition (dry or wet). Length isn't the only consideration.Jan 25, 2019

How do you read runway numbers?
Plainly put, airport runways are numbered according to compass bearings. This means runway numbers are based on the compass with 360 representing north, 90 representing east, 180 representing south, and 270 representing west. Runways are numbered between 01 and 36.
Is there a runway 00?
Single Physical Runways
When this rule results in a single digit number then the designator is preceded by a zero (e.g. if the runway cenreline azimuth is 82, then the designator will be 08). North-oriented runways are designated 36 (not 00).

What is basic runway length?
Runway length A runway of at least 6,000 ft (1,800 m) in length is usually adequate for aircraft weights below approximately 200,000 lb (90,000 kg). Larger aircraft including wide bodies will usually require at least 8,000 ft (2,400 m) at sea level and somewhat more at higher Altitude airports.
How long does a runway need to be for a 747?
The approx. 10,700 feet Wikipedia figure is for a fully loaded 747 at sea-level. The lighter the plane, the less runway it needs. The 7,500-foot runway at TNCM allows a takeoff at 84% of the maximum takeoff weight.Jul 13, 2017
How long is a runway for a 737?

What makes a boat's COG inaccurate?
The other major error factor which makes your COG and estimated position inaccurate. The first is leeway, or sideslip. Because the wind is blowing from the side of the boat, the boat is pushed sideways. This effect is most pronounced when sailing to windward and reduces as the wind moves aft and disappears running downwind.
How to calculate COG?
Calculating COG - Fix to Fix 1 Plot Point A and Point B on your chart. 2 Draw a straight line from A to B. 3 With a parallel rule, measure the compass angle of the line and record it. 4 Adjust the number for magnetic variation, adding West variation and subtracting East.
What is the heading of a boat?
The heading is the compass direction your boat is pointing, and it may not match COG if you have current and tidal effects. Heading is instantaneous, we derive COG from your boat's motion over time.
What is the effect of wind on a boat?
This effect is most pronounced when sailing to windward and reduces as the wind moves aft and disappears running downwind. The amount of leeway varies with boat speed, wind speed, and sailing conditions.
What does the runway number mean?
The runway number represent the first two digits of the runway’s actual three digit magnetic direction. Runways are oriented or pointed at angles with respect to the magnetic north pole. The magnetic north pole is where your compass points, and not the true north pole.
What is the magnetic direction of a runway?
Magnetic Direction. The runway number represent the first two digits of the runway’s actual three digit magnetic direction. Runways are oriented or pointed at angles with respect to the magnetic north pole. The magnetic north pole is where your compass points, and not the true north pole.
Is a drone a pilot?
Drones are Aircraft! When you fly a drone, you are a pilot. A Drone is an Aircraft, and there are very specific legal requirements for piloting a drone in Canada. Transport Canada Transport Canada (TC) is the Federal Institution responsible for transportation policies and programs in Canada.
How many degrees are in a circle?
Every circle has 360 degrees, and therefore 180 degrees is exactly half of the full rotation of a circle. As you see, Runway 3 (30 degrees) is paired with Runway 21 (210 degrees), and these two runways are 180 degree opposites. Runway Number: Two – Eight.
How is course similar to bearing?
Course. Course is very similar to bearing in that it’s the desired direction for your route of flight. If you are going directly from one airport to the other, your course and bearing will be the same along the route of flight. If you are flying from an airport to a VOR to another airport, your course will change in each leg, as will your bearing.
What is heading in airplanes?
This does not factor for wind, or the actual movement of the airplane across the ground. It only refers to what the compass reads based on where the nose is pointed.
What is the difference between a track and a heading?
Heading is the direction the airplane is pointed, whereas track is the actual direction of the airplane tracking across the ground. Bearing is the angle between any two points, whereas course is your intended path of travel to your destination. In the rest of this post we’ll elaborate on each of these points and then also provide ...
Why is bearing confusing?
Bearing can be confusing sometimes because has some overlap with course. Bearing is simply the angle or direction between two points. A practical application of this is in VOR navigation. It’s a common thing to hear someone say “we are bearing 090 from the station”.
What Is A "Back Course" Approach?
When you fly a localizer back course approach (LOC BC), you're navigating to the runway using horizontal guidance off of a localizer system, but in the opposite direction that you'd normally use the localizer. Navigation is very similar to a localizer-only approach, but with a few key differences.
Where You'll Find "Back Course" Approaches
You'll often find LOC BC approaches on runways with an ILS installed, but pointing in opposite direction. In Grand Forks, ND (KGFK), winds are predominantly out of the northwest. The ILS for KGFK's north-facing Runway 35L is also used to create a LOC BC approach to Runway 17R.
How To Set Up A "LOC BC" (Without HSI)
For pilots flying a LOC BC approach using a course deviation indicator (CDI) with an omni bearing selector (OBS), you must pay close attention to "reverse sensing" associated with the back course.
How To Set Up A "LOC BC" (With HSI)
If you're lucky enough to fly with a horizontal situation indicator (HSI), flying LOC BC approaches gets significantly easier. The HSI combines a heading indicator with CDI needles. As long as you tune the front course for the localizer, you won't get reverse sensing.
Flying The LOC BC Approach
Once you're established on a LOC BC approach, flying is as simple as any non-precision approach. You'll reference step down fixes and DME before leveling off at your minimum descent altitude (MDA).
Using An Autopilot? PUSH THE "BACK COURSE BUTTON"
When you fly an autopilot-coupled LOC BC approach, ALWAYS push the "back course button" if there's one installed for your autopilot system. By pushing this button, you're telling the autopilot to turn inbound on the back course instead of outbound. Here's the scenario...
Cog - A Complete Definition
- At its simplest level, imagine your sailboat dragged a chain on the bottom as you sailed, leaving a line through the mud and sand. It doesn't matter what your compass heading was or your angle of sail off the wind, your "Course Over Ground" is literally that line you drew on the bottom. It is the path the boat travels relative to the bottom, no mat...

- If you're not comfortable plotting a point on a chart and measuring a line, start with this guide to be sure you understand dead reckoning and how to plot a point and measure a line. Those skills are important to figuring your COG by either method. To calculate COG from point A to point B with a chart is simple if you understand the basics of plotting and measuring. 1. Plot Point A an…
Calculating Cog - Dead Reckoning
- This is where the calculations get useful and much more interesting. When you are navigating with dead reckoning and paper charts, you estimate your position based on information about your course and heading. But a current can move you miles off course, and you'll never feel it. Accounting for it and estimating it is how we calculate our Course Over Ground. To do this, you …
Course Over Ground - Why Bother?
- Since you have a COG function on your GPS, why take the time to learn how to calculate a less precise number on paper? And what can you do with the COG once you have it? The answer to "why bother" is the same one for why learn Dead Reckoning navigation - if you lose your instruments or there's a problem with the GPS system you still can get to a safe harbor or home…
