Study Notes

VOR Functionality

VORs operate using straight-line radio projections (radials) radiating in all directions, referencing Magnetic North.
Line-of-sight limitations affect the effective range of VORs.

Types of VFR Aeronautical Charts

Three main types are Sectional, VFR Terminal Area, and World Aeronautical Charts.

Sectional Charts

Provide essential information about airports, navigational aids, airspace classifications, topography, and ATC frequencies.

World Aeronautical Charts

Cover global land areas suitable for moderate-speed aircraft.
Similar in function to sectional charts but designed for international use.

Latitude and Longitude

Latitude lines run east to west, measuring distance north and south from the equator, ranging from 0 degrees at the equator to 90 degrees at the poles.
Longitude lines, also known as meridians, run north to south and measure east and west, extending up to 180 degrees.

Time Zone Calculations

Longitude degree separation impacts time zones, with each zone representing a 15-degree section of longitude.

True North vs. Magnetic North

True North is a line from any point on Earth to the North Pole, with all lines of longitude representing true north.
Magnetic North indicates the direction to the north magnetic pole, represented by a line with half an arrowhead.

Magnetic Variation and Course

Magnetic Variation is the angular difference between True North and Magnetic North.
Magnetic Course represents a heading after adjusting for magnetic variations from a true course.

Magnetic Deviation

Magnetic Deviation occurs when the compass needle's reading is affected by magnetic influences within the aircraft, leading to inaccuracies.

Compass Terms

"Swinging the Compass" involves compensating for Magnetic Deviation.
Compass Heading is the magnetic heading adjusted for deviation caused by aircraft electrical systems.

Track is the actual path of the aircraft over the ground, independent of the intended true course.
Compass Heading calculation involves True Heading adjusted by Variation and Deviation.

Flight Time and Distance Calculations

Time in flight can be calculated using Distance divided by Ground Speed (GS).
Distance flown is determined by multiplying Ground Speed (GS) by time.
Ground Speed (GS) is calculated as Distance divided by time.

Fuel Calculation

Required fuel for a flight is estimated by multiplying flight time by the fuel consumption rate.

Pilotage and Dead Reckoning

Pilotage involves navigating by correlating ground features with their map counterparts.
Dead Reckoning is navigation based on time, distance, and heading calculations.

Logical Order of Flight Planning

Determine altitude, measure total distance, calculate True Heading to derivation of Course Heading (considering Wind Correction Angle, Variation, and Deviation), determine Ground Speed, calculate Time, and estimate fuel burn.

Three available systems include VHF Omnidirectional Range (VOR), Nondirectional Radio Beacon (NDB), and Global Positioning System (GPS).

Classes of VOR

VOR systems are classified into three classes:
- T for Terminal
- L for Low Altitude
- H for High Altitude.
