What does the 1 in 60 rule state?
In air navigation, the 1 in 60 rule is a rule of thumb which states that if a pilot has travelled sixty miles then an error in track of one mile is approximately a 1° error in heading, and proportionately more for larger errors.
What is the rule of thumb for leveling off on a set heading?
Use one-half of the bank angle to begin a rollout to a heading. For a 30° bank, begin the rollout 15° early. Lead a level off from a climb or descent by 10% of the vertical speed. If the climb rate is 500 FPM, initiate the level-off 50′ early.
What distance off course would an aircraft be with one dot deflection 30 miles out from the VOR station?
Depending on your range from the VOR station, each dot on the course deviation indicator (CDI) represents a variable off-course lateral distance. At 30 nm from the station, a one-dot deflection of the CDI needle means that you’re one mile off course; 15 miles out, one dot equals one-half mile off the intended track.
How often are planes off course?
The plane takes off at the appointed hour toward that predetermined destination. But in fact, the plane is off course at least 90 percent of the time. Weather conditions, turbulence, and other factors cause it to get off track.
How many degrees is a VOR?
VOR: Radials Each course is aligned with a specific degree on the compass, with 0 degrees pointing north, 90 degrees pointing east, 270 degrees pointing west, and so on. Using your airborne VOR equipment, you can navigate on any one of these 360 courses while going directly to or from a VOR station.
What does VOR stand for?
VHF Omnidirectional Radio Range

How far away can you pick up a VOR?
The VOR Navigational Station Terminal VORs are designed to be clearly received up to 25 nautical miles from the station at altitudes of 1,000 feet agl through 12,000 feet agl. Low-altitude VORs are meant to be used from 1,000 feet agl through 18,000 feet agl at distances of up to 40 nm from the station.
How do you tell if a VOR is high or low?
As far as high/low VOR, one way to tell is to look at the High/Low enroute IFR charts. You can see two VOR stations on here labeled Minot Intl and Devils Lake Rgnl with a victor airway between them (V430).
What equipment is required for using the VOR?
Aircraft equipment includes a VOR antenna, a VOR frequency selector, and a cockpit instrument. The instrument type varies but consists of one of the following: an Omni-Bearing Indicator (OBI), Horizontal Situation Indicator (HSI) or a Radio Magnetic Indicator (RMI), or a combination of two different kinds.
Are VOR radials magnetic or true?
VOR degrees are magnetic, not true, so you can read your magnetic course for that location right from the VOR rose. Again, the difference between the true course you’ve drawn on your chart and the magnetic course that runs through the VOR rose is the magnetic variation.
How does ADF work in aircraft?
The ADF is a form of ‘radio compass’ that provides the pilot with the relative bearing of the beacon to which the equipment is tuned. The ADF works by using the electromagnetic properties of the signal produced by the beacon. Two antennae are required, which are known as the loop antenna and the sense antenna.
How many radials does a VOR have?
360 radials
What is the difference between heading and bearing?
Heading is the direction the aircraft is pointing. The aircraft may be drifting a little or a lot due to a crosswind. Bearing is the angle in degrees (clockwise) between North and the direction to the destination or nav aid.
What is range and bearing?
The Range and Bearing Controls show the distance, azimuth, and back azimuth of a great circle line connecting two positions on the Earth’s surface. The values are computed for a great circle path on the ellipsoidal Earth, using the numerical latitude and longitude values, not the line on the display.
What is a true bearing?
A true bearing expresses the direction in terms of the angle made with North, the angle always being drawn clockwise. For example: In the diagram at right the angle drawn clockwise from North is 35°. Thus its true bearing is 35°T. (The T signifies a true bearing.)
When changing from a compass course to a true course you should apply?
To convert a compass course into a true course we can use the original equation. If we have steered a compass course of 200°, we have to plot a true course of 203° in the chart if the variation is 3° East , or a true course of 190° if the variation is 10° West .
How do you know if a course is true?
Navigational Plotter Instructions
- Use your plotter to determine the true course (TC), the total distance of your flight, and.
- Place the small hole in the center of the protractor section over a meridian (line of.
- If your course is nearly north or south and does not cross a meridian, place the hole of.
Why does deviation change with heading?
Variation is different for each location on the Earth and is mentioned on the compass rose on each nautical chart. The amount of variation slightly changes with time due to the slow migration of the Earth’s magnetic poles. Practically, the compass deviation depends on the heading of the ship.
