Is a compass correction card required?
A placard (correction card) must be installed on, or near, the magnetic direction indicator.
How important is compass correction?
Failure to maintain a magnetic compass in good working condition or to monitor deviations may result in a vessel being delayed or detained and potentially the vessel owner and/or master being prosecuted.
What is a compass card aviation?
The compass deviation card in your airplane is the little label stuck somewhere near your magnetic compass that tells you about the unresolveable errors that remain between the displayed compass heading and the actual magnetic heading of the airplane.
What does swinging the compass mean?
Compass-swing definition (nautical) The process of swinging and compensating a ship or aircraft compass by determining and reducing the deviation coefficients and recording the residual deviations; now done by computer.
How long is a compass deviation card valid for?
two yearsThe Administration requires that the Deviation cards are be reviewed every two years.
What are the three types of compass errors?
Magnetic Compass Errors:Variation.Deviation.Magnetic Dip.Oscillation.Northerly Turning Error (part of magnetic dip)Acceleration/Deceleration Errors (part of magnetic dip)
Where is the compass correction card located?
References in periodicals archive ? A compass correction card should be placed next to the instrument to allow pilots to compensate for this error. Once the compass has been swung successfully, the results are recorded on a compass correction card, which is mounted next to the compass.
What are compass errors?
Definition of compass error : the difference between compass heading and true heading expressed as the algebraic sum of variation and deviation.
How do I get a deviation card?
A deviation card is produced after your onboard compass, usually located at the wheel binnacle, has been swung. Ideally this is done annually. The compass deviation card marks deviation, as the name suggests, for different headings. Readings are usually taken at 30 degree intervals from 000 and 360 degrees.

What is a card posted in a holder near the magnetic compass?
A card posted in a holder near the magnetic compass, on which there is recorded the difference between the readings of the compass and the correct geomagnetic directions; these errors (deviations) are given for at least the four cardinal points; sometimes the card lists the compass bearings to be flown when it is desired to fly corresponding magnetic headings.
What is a small card in a cockpit?
A small card placed in the cockpit to show the compass deviation for each heading. The card reads the courses to be steered in lieu of the required headings. Also called a deviation card.

On today's flight it was light and variable and I was in some empty airspace. I decided to update my compass correction card by flying the 30's compass headings using my GPS and then letting the compass settle on a number and writing it down. I now have a new compass correction card.
