Types of Attitude Indicators Types of Attitude Indicators: From Traditional to Digital Attitude Indicators

The attitude indicator is one of the six basic flight instruments found in any cockpit. At a glance, it gives the pilot a clear picture of the aircraft's relative position to the Earth's horizon. With one simple dial, the pilot can see whether the plane is climbing, banking or descending. Without it, a pilot has to cobble together a picture of the aircraft's attitude from other instruments such as the turn and bank indicator and vertical speed indicator.

5 Reasons to Buy a Used Airplane 5 Reasons to Buy a Used Airplane

If you're in the market for a new-to-you aircraft, you may be trying to decide between buying a new or a used airplane. The right answer will depend on your expected use case and budget, i.e are you a private pilot looking to switch from renting to owning? Or, are you a Part 135 charter operator looking to expand your fleet?

First, take a look at the options available to you. In 2018 for example, 2,443 general aviation aircraft of all kinds were manufactured, from single-engine trainers to business jets, according to the General Aviation Manufacturers Association. However, there are already more than 200,000 general aviation aircraft based in the U.S., so there are plenty of used aircraft to choose from.

Round Dial vs. Glass Cockpit Round Dial vs. Glass Cockpit: Which is Better?

Round dials in a cockpit, also called analog gauges, have been standard in aircraft since the early days of aviation. Glass cockpits, or electronic flight instrument systems, began appearing in commercial aircraft in the late 1990s, and by 2003 they were starting to appear in general aviation airplanes.

Most general aviation aircraft can be ordered with glass cockpits, and older aircraft can be retrofitted to take advantage of the new technology.

Which is best? We'll take a look at the differences between a glass cockpit and an analog cockpit.

How To Choose The Right Aircraft Inverter Calculating Your System Load: How To Choose The Right Aircraft Inverter

Power inverters convert the aircraft’s battery from one type of power to another so electronic devices are compatible, from auxiliary aircraft equipment to passenger and pilot accessories. Here’s how to make sure you have the right inverter for your aircraft’s needs.

Attitude Indictors Attitude Indictor Explained: My Air-Driven Instrument Stopped Working

Many general aviation aircraft use mechanical attitude indicators that rely on a vacuum or pressure pump to spin the gyroscope inside the instrument. The vacuum pump draws air, or the pressure pump forces air, through a system of pendulous vanes that are used to erect the gyro. When the aircraft is level, the air flows across the vanes evenly. When the aircraft turns, the vanes shift, creating an imbalance in the airflow that the gyro reacts to returning to the upright position...

How Directional Gyros Work Accurate Flight Instruments: How Directional Gyros Work

As a pilot, making good time is always great, but knowing where you are is more important. That’s why you need accurate flight instruments to operate from point A to B safely, which is where the directional gyro comes in. Directional gyros indicate the direction that the aircraft is heading.

My Attitude Indicator Isn't Working Attitude Indicator Explained: My Attitude Indicator Isn't Working

Depending on your flight plan, failure of the attitude indicator (AI) may not keep you from flying. Often, common attitude indicator errors will give you a hint that it's time to have the instrument examined by a professional. It may only need an overhaul, or it could be time to replace the unit.

How Instantaneous Vertical Speed Indicators Combat Lag Time How Instantaneous Vertical Speed Indicators Combat Lag Time

Vertical speed indicators (VSI) measure the change in static pressure due to a change in altitude and present this information as the rate of climb or descent. Because the pointer on the VSI instrument face responds to the difference in pressure between two areas in the instrument, there is often a lag of six to nine seconds for the pressure differential to be established before the VSI can show the actual climb or descent rate, according to the Federal Aviation Administration.

Why Is My Airspeed Indicator Leaking? Airspeed Indicator Explained: Why Is My Airspeed Indicator Leaking?

Every aircraft with a standard category airworthiness certificate must carry a working airspeed indicator, which must be checked every 24 months as part of the FAR 91.411 inspection procedures. If you notice a problem with the airspeed indicator you should have it checked immediately by an appropriately certified mechanic.
