The Math / Science

1. b = Re + sA.
2. a = Re + oA.
3. c is the slant range.
4. CA is the Earth Central Angle.
5. BA is the subtended angle (β)
6. AA is elevation angle (α) + 90°

## How do you calculate Dant slant range?

A 1 degree offset angle at 60 nm equates to 1 nm of displacement.

1. Distance off track = (number of degrees off course x distance to station)/60.
2. Maximum drift angle (Max Drift) = Windspeed divided by Groundspeed in miles per minute.
3. Slant Range Overhead DME = Altitude in feet/6000.

## What is ground range?

ground range In radar terminology, the distance between the nadir and an object. See also RANGE. A Dictionary of Earth Sciences. × “ground range .”

## What is slant range in aviation?

The slant range (1) is the hypotenuse of the triangle represented by the altitude of the aircraft and the distance between the radar antenna and the aircraft’s ground track (point (3) on the earth directly below the aircraft).

## What is ADF in aviation?

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

## What is VOR in aviation?

VHF Omnidirectional Radio Range (VOR), is an aircraft navigation system operating in the VHF band. Alternatively, the VOR radial may be combined with magnetic heading from the aircraft compass to provide a bearing relative to the aircraft axis, which cn be used to home to the beacon.

## How far away can you pick up a VOR?

The VOR Navigational Station Terminal VORs are designed to be clearly received up to 25 nautical miles from the station at altitudes of 1,000 feet agl through 12,000 feet agl. Low-altitude VORs are meant to be used from 1,000 feet agl through 18,000 feet agl at distances of up to 40 nm from the station.

## How do you tell if a VOR is high or low?

As far as high/low VOR, one way to tell is to look at the High/Low enroute IFR charts. You can see two VOR stations on here labeled Minot Intl and Devils Lake Rgnl with a victor airway between them (V430).

## Can you file IFR to an airport without an approach?

You cannot file an IFR flight plan to an airport without an instrument approach. B. If the weather is forecast to be at least VFR at the expected time of arrival.

## How much does it cost to get an IFR rating?

An instrument rating costs around \$8,000 which is primarily driven by the 40 required actual or simulated instrument flight training hours, as well as small costs for study materials and examination fees.

## How hard is it to get IFR rating?

Getting your airplane instrument rating isn’t as hard as you might think. At least a private pilot certificate in airplanes, or are currently in the process of getting it. Take a written test (knowledge test) and an oral & flight test with an examiner in either an airplane or FAA-approved simulator (practical test).

## How long is IFR written test good for?

How long is a satisfactorily completed knowledge test valid? A satisfactorily completed knowledge test expires 24 calendar-months after the month it was taken. If a practical test is not satisfactorily completed during that period, another knowledge test must be taken.
