How do you obtain gyro error with the ship at wharf?

There are numerous ways to determine gyro error while pierside. At a minium all methods below require accurate charts and a device for taking a line of position (i.e. bearing circle or sextant).Here are the methods I know of:Celestial fixes (i.e. Amplitude of the Sun or Azimuth of the Sun (or Polaris))This method is complicated and time consuming. It requires knowledge of how to take celestial fixes as well as the Almanacs (or computer programs) to complete it.Process:Shoot a bearing to the celestial body.Enter time and location (Latitude and Longitude) of fix into reduction tables (in Almanac). This provides the what the body should bear.Subtract the bearing from Almanac from the visual bearing. Negative bearing error is to the East. Positive Error is to the West. Hopefully your error is less than 1 degree.Pierside [visual] Fix / "Trial and Error"MethodThis method is very time consuming but is simple enough for anyone with basic visual navigation skills to complete.Process:Shoot three (or more) lines of position (LOP).Plot on chart. If you end up with a pinpoint fix then assume you have no gyro error. However, in the more likely case that the fix is not exact (looks like a triangle), estimate equal amounts of error for each LOP.Repeat this method adding in error until you achieve a pinpoint fix. When pinpoint is achieved, whatever estimated error was used is the actual error.Distant Object Method / Radian Rule Method(I'll finish this response tomorrow)

How do you steer with gyro error?

For my answer I will assume we are speaking of steering a ship.In order to steer with gyro compass error the error must be known. There are many ways to determine this (Azimuth of the Sun, Amplitude of the Sun, Azimuth of Polaris, Distant Object Method). Actually performing these is beyond the scope of this question however if you would like instructions how the American Practical Navigator is the place to go.Error is usually less than a degree. No ship's captain or master would be happy with bearing error in whole degrees.Once the error is know, simple arithmetic will allow you to steer the desired course. To obtain the course to steer the error is added to the desired true heading. Consider East error to be negative and West error to be positive. This is often remembered by using "East is Least; West is Best."Formula:S = Heading to steerE = ErrorD = Desired True HeadingS = D + E


Is there a binnacle on an airplane?

No, while airplanes have both magnetic and gyro compases, they are not contained in a binnacle. The binnacle was the compass holding housing on ship which allowed the compass to stay level when the ship moved with the waves

What is the Cause of gyro compass failure in higher latitude?

It is not so much of a failure but an Heading offset caused by"Speed Error"The speed error is an error generated when a vessel/aircraft in which a gyrocompass is installed transits a course other than east or west. Its value is determined depending on the ship's speed, course, and latitude. (It is not related to the kind or type of gyrocompass.)The north-seeking tendency of a gyrocompass is based on the earth's rotation. When a ship sails, the resultant motion of the ship's motion and the earth's rotation acts on the north-seeking tendency of the gyro. If the course of the ship deviates towards the north or south, the direction of the resultant motion deviates north or south and thus an error occurs because the north-seeking force of the gyro acts perpendicular to this resultant motion. That is, the speed error is the angle of the difference between this resultant motion and the east-west direction.Determining Speed Errorϕ: LatitudeK: Speed of the earth's rotation at theequator (About 900 kt)V: Vessel/Aircraft speed (kt)θ: Gyrocompass courseδ: Speed errorIn the figure above, AC = Vcos θ = Kcos ϕ • sin δSince δ is a small value,sinδ = δ (radian) = 1/57.3 δ (unit: degree)From these equations, δ = 57.3 Vcos θ/900 cos ϕIf we assume, for example, that the ship is at the equator ( ϕ = 0), the gyrocompass course is N ( θ =0), and the ship's speed is 30 kt, thenδ = 57.3 × 30/900 = 1.91 degrees = 1°54'When the value of θ is between 270° to 90°, the compass indication increases. Therefore, theship's true course is as shown below.0° − 1°54' = 358°6'As seen above, if the compass course deviates towards the north, the true course can be obtained by subtracting the speed error from the compass course, and if the course deviates towards the south, the true course is obtained by adding the speed error to the compass course.Most modern Gyros can automatically compensate for this error when interfaced to a GPS/SatNav/GLONASS (position/Speed) and w or w/o a Speed Log (speed). These values can also be entered in Manually to calculate speed error. See CMZ900 by Yokogawa and marketed by AGMarine. Just a little plug if that's alright?In the same location when we compare 2 vessels have same heading; we can come to that conclusion from formula "57.3 Vcos θ", higher speed will cause bigger speed error.
