What is IVAO ?

IVAO is a non-profit organisation dedicated to providing flight-simulation enthusiasts with access to servers that allow them to fly online with other people, either in the role of an air traffic controller or a pilot. The main difference from most other networks is that IVAO simulates scheduled air traffic and general aviation as opposed to military combat simmer groups.


What is an IFR Flight ?

Instrument Flight Rules (IFR) is a set of regulations and procedures for flying aircraft without the assumption that pilots will be able to see and avoid obstacles, terrain, and other air traffic; it is an alternative to visual flight rules (VFR), where the pilot is primarily or exclusively responsible for see-and-avoid. Since navigation and control of the aircraft under IFR is done by instruments, flying through clouds is allowed; under VFR it is not.


What is a VFR flight ?

Visual flight rules (VFR) are a set of aviation regulations under which a pilot may operate an aircraft in weather conditions sufficient to allow the pilot, by visual reference to the environment outside the cockpit, to control the aircraft's attitude, navigate, and maintain safe separation from obstacles such as terrain, buildings, and other aircraft.


What is an ILS ?

The Instrument Landing System (ILS) is an instrument approach system which provides precise guidance to an aircraft approaching a runway and in the case of one type of Category III approach, it also provides guidance along the runway surface.


What is icao ?

The International Civil Aviation Organization (ICAO), an agency of the United Nations, codifies the principles and techniques of international air navigation and fosters the planning and development of international air transport to ensure safe and orderly growth.


What does an atc do ?

Air traffic control (ATC) is a service provided by ground-based controllers who direct aircraft on the ground and in the air. A controller's primary task is to separate certain aircraft to prevent them from coming too close to each other horizontally or vertically. Secondary tasks include ensuring orderly and expeditious flow of traffic and providing information to pilots, such as weather and navigation information.


What is an FMC ?

A flight management system or FMS is a computerized avionics component found on most commercial and business aircraft to assist pilots in navigation, flight planning, and aircraft control functions. It is considered to be composed of four major components: FMC (Flight Management Computer), AFS (Auto Flight System), Navigation System including IRS (Inertial Reference System) and GPS, and EFIS (Electronic Flight Instrument System).


What is an FIR ?

A Flight Information Region (FIR) is an aviation term used to describe airspace with specific dimensions, in which a Flight Information Service and an Alerting service are provided. It is the largest regular division of airspace in use in the world today.


What is are NOTAMs ?

NOTAM or NoTAM is the quasi-acronym for a "Notice To Airmen". NOTAMs are created and transmitted by government agencies under guidelines specified by Annex 15: Aeronautical Information Services of the International Convention on Civil Aviation. A NOTAM is filed with an aviation authority to alert aircraft pilots of any hazards en route or at a specific location. The authority in turn provides means of disseminating relevant NOTAMs to pilots.
