The courseline is selected by turning an “omni bearing selector” or “OBS” knob usually located in the lower left of the indicator. It then shows the number of degrees deviation between the aircraft’s current position and the “radial” line emanating from the signal source at the given bearing.

What does obs mean with VOR?

If the line is to the left, go left. A VOR has three elements: an omnibearing selector (OBS), a course deviation indicator (CDI), and a TO/FROM indicator. The OBS allows you to select the line of direction that the VOR tracks. The CDI indicates how many degrees the aircraft is off that line, and in which direction.

How does a course deviation indicator work?

A course deviation indicator (CDI) is an avionics instrument used in aircraft navigation to determine an aircraft’s lateral position in relation to a course to or from a radio navigation beacon. If the location of the aircraft is to the left of this course, the needle deflects to the right, and vice versa.

What function does the OBS perform?

Features. High performance real time video/audio capturing and mixing. Create scenes made up of multiple sources including window captures, images, text, browser windows, webcams, capture cards and more. Set up an unlimited number of scenes you can switch between seamlessly via custom transitions.

What is CDI and OBS?

A standalone CDI (Course Deviation Indicator) is an instrument that shows your deviation from a VOR radial that is selected using the OBS (Omnibearing Selector) knob located on the instrument itself. An HSI (Horizontal Situation Indicator) is an entirely separate instrument that combines a CDI and a heading indicator.

What is a vot aviation?

VOR Test Facility (VOT): A ground facility which emits a test signal to check VOR receiver accuracy. Some VOTs are available to the user while airborne, while others are limited to ground use only.

What is an ADF aviation?

The Automatic Direction Finder (ADF) is an aircraft navigation product that automatically calculates the relative bearing of the aircraft to the radio station.

How much does OBS cost?

Users can access Streamlabs OBS for free, but a paid upgrade is required to access premium features. Prime, which is the paid software from Streamlabs OBS, costs $19/month or $149/year.

How do you read a CDI indicator?

On the CDI instrument just read the number displayed on the compass card (±90° of the radial). In the left figure above, the shortest path to join the VOR radial is 340° (=070°-090°) (blue straight arrow). The VOR is located in the sector between 340° and 070° as we are in the TO region.

Where do OBS recordings go?

For OBS Studio, you can find where the directory for recordings currently is by going to File and then Show Recordings. This will open up the directory on Windows, OSX, or Linux to where your recording path is currently set.

Does OBS record audio?

OBS (Open Broadcaster Software) is a free piece of software that is designed for streaming and recording audio and video sources on Mac or Windows. … The great thing about OBS (other than being free) is that it can record from almost any audio or video source, internal or external.

What is FLC in aviation?

“Flight Level Change” Mode, or “Speed” Mode, adjusts aircraft pitch to maintain a constant indicated airspeed. When you engage FLC during a climb or descent, the autopilot will hold the aircraft in the climb or descent at the airspeed you’ve selected. … Conversely, when you reduce power, vertical speed decreases.

What is VOR in aviation?

Description. The Very High Frequency Omni-Directional Range (VOR) is a ground-based electronic system that provides azimuth information for high and low altitude routes and airport approaches.

How many dots are on a CDI?

ILS/VOR CDI Deviation RNAV There are two types of CDI display: 2 dot and 5 dot. The key to this question is to remember what full scale deflection means for both of these displays. In VOR mode, full scale deflection is 10°. In ILS mode, full scale deflection in the localiser is 2.5°.

What is a VOR indicator?

The VOR Indicator The direction of deflection tells the pilot where he is relative to the radial, while the dots on the instrument’s face tell the pilot how many degrees he is off his course. Each dot represents a 2-degree deflection from the desired course.

What is a VOR beacon?

In radio navigation, a VOR/DME is a radio beacon that combines a VHF omnidirectional range (VOR) with a distance measuring equipment (DME). The VOR allows the receiver to measure its bearing to or from the beacon, while the DME provides the slant distance between the receiver and the station.

What are OBS scenes?

Scenes and Sources are the meat of OBS Studio. These are where you set up your stream layout, add your games, webcams, and any other devices or media that you want in the output. … This means if you name a source Game, you can’t have a Scene with the name Game.

How many scenes can you have in OBS?

Active Member There is no hard limit of scenes and sources. However, every scene and every source, and every filter applied to a source, needs a bit of system and GPU resources, so the actual number supported by OBS depends on the power of the CPU and GPU.

How do I record with OBS?

1. Launch OBS and scroll down to the Sources box.
2. Click the tiny plus button to access the options panel and select Screen Capture. …
3. Click OK when prompted by pop-ups. …
4. Go to Settings and click on Output. …
5. Navigate to the bottom-right corner of the screen, and hit the Start Recording button.

Is ADF required for IFR?

IFR approved GPS can be substituted for ADF in any approach except for a pure NDB approach. Nobody is installing ADF, and there’s no need to.

What is aircraft DME?

The Distance Measuring Equipment (DME) is a radio navigation aid used by pilots to determine the aircraft’s slant range from the DME ground station location. … The DME measures the distance from the aircraft to the runway out to 18 Nautical Miles (NM) and beyond.

What is ADF Cessna?

The ADF. Your automatic direction finder, or ADF is a basic instrument that transmits location information on the AM band. To use, tune it to a non-directional beacon (or NDB). … The ADF on a Cessna 172. The ADF always points to the station.

Can a vot check be done in the air?

Airborne VOR Check: VOR equipment can also be checked for accuracy in flight. … Note the VOR bearing indicated by the receiver when over the ground point. The maximum indicated bearing error is plus or minus 6 degrees.

Is VOR required for IFR?

Navigation equipment is included on the list of equipment. Although a VOR can be used to satisfy the navigation equipment requirements, a VOR is not specifically required. GPS is a suitable radio receiver which can be used for both IFR and VFR operations instead of or in addition to VOR.

Is DME line of sight?

DME requires line-of-sight between the aircraft and the ground station, and terrain and distance beyond the horizon will prevent DME from working. Ground-based DME transmitters are also rated to handle roughly 100 aircraft at a time.

What is cone of confusion VOR?

A cone-shaped volume of airspace directly above a VOR station where no signal is received, causing the CDI to fluctuate.

How do you read VOR radials?

Fly the direction of the desired radial. Set the radial’s direction into the OBS and turn the aircraft to fly that heading. Once established on the heading, note the position of the CDI. If it is to the right, your radial is to the right. Likewise, if it is left, the radial is left.

Does OBS require Internet?

The OBS installer does not require an internet connection, however it does expect to have the VS 2017 runtimes and UCRT already installed. If those are missing, it will prompt you to install them.

Is OBS a paid app?
