Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Turn Coordinator shopping experience:

1. Compare - without doubt the biggest advantage that the Turn Coordinator offers shoppers today is the ability to compare thousands of Turn Coordinator at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.

2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about

3. Testimonials - don't know anybody that has bought a Turn Coordinator? Wrong! If the Turn Coordinator is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.

4. Questions - Got a question about Turn Coordinator then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....

5. Reputation - Never heard of the company selling Turn Coordinator? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Turn Coordinator and build up a picture of their reputation for sales, returns, customer service, delivery etc.

6. Returns - still worried that even after all of the above your Turn Coordinator wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.

7. Feedback - happy with your Turn Coordinator then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.

8. Security - check for the yellow padlock on the Turn Coordinator site before you buy, and the s after http:/ /i.e. https:// = a secure site

9. Contact - got a question about Turn Coordinator, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.

10. Payment - ready to pay for your Turn Coordinator, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

Coordinated flight right turn.

The turn coordinator is an aircraft instrument which displays to a aviator information about the rate of turn, rate of roll, and the 'quality' or 'coordination' of the turn. The turn coordinator was developed to replace the older turn and bank indicator, which displayed rate and quality of turn but not rate of roll.

The turn coordinator is, like the turn and bank instrument it replaced, a gyroscopic instrument. An internal gyroscope, typically electrically driven, spins at approximately 20,000 rpm. As the aircraft turns, the principle of gyroscopic inertia causes the gyro to tilt. This tilting force works against a spring; thus, a slow rate of turn deflects the gyro slightly while a higher rate of turn deflects it more. The gyroscope's movements are linked to an indicator on the front face of the turn coordinator.

The indicator looks like a little airplane seen from behind: when the airplane is level, the rate of turn is zero; when it is tilted, the amount and direction of tilt show the pilot the rate of turn. The wings of the symbolic airplane line up on white tick marks at the level position to indicate zero rate of turn. There is another set of tick marks below the level pair. When the symbolic aircraft is tilted so as to align with one of the tick marks, the aircraft is said to be turning at standard rate of turn, which is 3 degrees of heading change per second. This is often marked on the face plate of the instrument as '2 minutes', since it takes two minutes to complete a 360° heading change when turning at 3°/s.

The quality of turn is indicated by an inclinometer. This is a glass tube mounted on the face of the instrument, below the symbolic airplane. It is actually a completely separate instrument. The inclinometer consists of a glass tube filled with kerosene, and a steel ball. The tube is curved such that its center is the lowest point, and each end is higher. Normally, the ball will then sit in the center position of the tube, which represents a 'coordinated' turn. This position is marked by two vertical wires on the tube. The ball is said to be 'centered' when it sits perfectly evenly between the two wires.

The ball is used typically to tell the pilot the correct amount of rudder input is being applied, usually during rolls and turns. If the rudder input produces a coordinated turn, the ball will remain centered during a roll maneuver. If the ball deflects into the roll, the rudder input was insufficient, indicating a slip (aerodynamic); if it deflects opposite the direction of the roll, the rudder input was excessive, indicating a skid (aerodynamic). The old adage "step on the ball" refers to the pilot having to apply rudder in the same direction as the ball is deflected in order to return the aircraft to coordinated flight.

The turn coordinator differs from the older turn and bank indicator in that the turn coordinator has the gyro mounted at a 30-degree tilt. This allows the turn coordinator to respond to roll as well as turn. When the aircraft is rolling, the turn coordinator deflection is proportional to the rate of roll and not the rate of turn. Once the roll has stopped, the turn coordinator deflection will settle back to an amount which indicates the rate of turn. Pilots who are unfamiliar with this principle sometimes have difficulty using the turn coordinator properly, as they may see a roll indication and interpret it as a rate of turn.

The turn coordinator should be used as a performance instrument when the attitude indicator has failed. Called 'partial panel' operations, this can be unnecessarily difficult or even impossible if either (1) the pilot does not understand that the instrument is showing roll rates at some times and turn rates at others, and (2) if the internal dashpot is worn out. In the latter case the instrument is said to be underdamped; in turbulence it will indicate large full-scale deflections to the left and right, all of which are roll rate responses. In this condition it may not be possible for the pilot to maintain control of the aircraft in partial-panel operations in instrument meteorological conditions.
