To calculate an intercept angle, double the difference between the bearing to intercept and the current bearing to the station. If tracking inbound, use ‘TO’ bearings, otherwise, use ‘FROM’ bearings (“radials”). Cap the result at a minimum of 20º and a maximum of 90º.

How do you find the intercept angle?

To calculate an intercept angle, double the difference between the bearing to intercept and the current bearing to the station. If tracking inbound, use ‘TO’ bearings, otherwise, use ‘FROM’ bearings (“radials”). Cap the result at a minimum of 20º and a maximum of 90º.

What is reverse sensing VOR?

In “reverse sensing,” the instrument is displaying exactly what you’re telling it to display. It takes some effort from the pilot to not become “reversed.” Where pilots get confused and think that the instrument is reversed is when the OBS is set to the reciprocal of the course they want to fly.

What is VOR radial?

VORs broadcast a VHF radio composite signal including the station’s Morse Code identifier (and sometimes a voice identifier), and data that allows the airborne receiving equipment to derive the magnetic bearing from the station to the aircraft. This line of position is called the “radial”.

How do you use VOR radial?

To fly a specific VOR radial inbound to a VOR station, use the OBS to place the radial you want to fly inbound on the reciprocal course index on the bottom of the VOR indicator. You should have a To indication, and the CDI needle will deflect in the direction you need to turn to get to the station.

What does the word intercepting mean?

1a : to stop, seize, or interrupt in progress or course or before arrival. b : to receive (a communication or signal directed elsewhere) usually secretly. 2a : to gain possession of (an opponent’s pass) b : to intercept a pass thrown by (an opponent)

What is intercept angle?

An intercept is a point at which the curve intersects the -axis. A intercept is a point at which the curve intersects the. -axis. Inscribed Angle TheoremThe Inscribed Angle Theorem states that the measure of an inscribed angle is half the measure of its intercepted arc.

What is the frequency range of the VOR?

VORs operate within the 108.0 to 117.95 MHz frequency band and have a power output necessary to provide coverage within their assigned operational service volume. They are subject to line-of-sight restrictions, and the range varies proportionally to the altitude of the receiving equipment.

What angle should you intercept a localizer at?

Localizer intercept angle – This should be no more than a 20- or 30-degree angle.

What important factors must a navigator consider when selecting VOR sites?

The angles to the VOR stations must have significant offset angles relative to each other. The distance to the VOR station must be appropriate for the elevation of the aircraft.

Article first time published on

Are VORs still used?

AOPA asks the strategy as FAA switches off VORs As of April, the FAA had discontinued 23 of the more than 300 ground-based navaids it plans to shut down by 2025 as more aircraft equip to fly performance-based navigation routings enabled by GPS.

When navigating VOR when will you have reverse sensing?

Reverse sensing occurs when the current heading is on the bottom half of the VOR. Taking this theory to the HSI where the currently flown heading is always on the top half and you can never have reverse sensing. It is also proper technique to set in the front course when flying a LOC/BC approach.

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.

Can you reverse sense on a VOR?

Reverse sensing occurs on the back course using standard VOR equipment. With a horizontal situation indicator (HSI) system, reverse sensing is eliminated if it is set appropriately to the front course.

How do you navigate a plane?

1. Global Positioning System (GPS)
2. Inertial Reference Systems (IRS)
3. Radio Aids (VORs, DMEs, ADFs, ILSs)

Which arc does intercept?

The red arc is the arc intercepted by that angle. When two straight lines cross a circle, the part of the circle between the intersection points is called the intercepted arc.

What arcs does each angle intercept?

The intercepted arc is formed by line segments intercepting the circumference of a circle. It is a part of the circumference of the circle. … The intercepted arc is twice the size of the inscribed angle. The intercepted arc is equal to the central angle.

What is interception geography?

Interception is the part of the rainfall that is intercepted by the earth’s surface and which subsequently evaporates. In this definition the earth’s surface includes everything that becomes wet after a rainfall event and that dries out soon after. … For example canopy, forest floor, fog, snow, and urban interception.

How do you use intercept in Word?

1. I leaped into the air, attempting to intercept the football before it landed in Bernie’s hands.
2. The knight held out a shield to intercept the arrows which were being shot in his direction.
3. The CIA uses high tech technology to intercept the communication between foreign countries and its spies.

What is the root word of intercept?

1400, “to cut off” (a line), “prevent” (the spread of a disease), from Latin interceptus, past participle of intercipere “take or seize between, to seize in passing,” from inter “between” (see inter-) + -cipere, combining form of capere “to take, catch,” from PIE root *kap- “to grasp.” Related: Intercepted; …

Is a radial to or from a VOR?

The radial gives the relative position of an aircraft to e.g. a VOR. There is no mathematical relation between the radial and the heading (or track) of an aircraft, i.e. one cannot be derived from the other.

How many degrees is each dot on a CDI?

This can be used to find and follow the desired radial. Deflection is 10° deviation at full scale (each side), with each dot on the CDI representing 2°.

How far off course is 1 degree?

Experts in air navigation have a rule of thumb known as the 1 in 60 rule. It states that for every 1 degree a plane veers off its course, it misses its target destination by 1 mile for every 60 miles you fly. This means that the further you travel, the further you are from your destination.

How much more sensitive is a localizer than a VOR?

Localizer specs Localizer course widths range between 3º and 6º. The specific angle chosen puts the course width at the runway threshold at about 700′. Typically, this is a 5° total width (or 2.5º full deflection to each side), four times more sensitive than a VOR.
