Aircraft position reports are sent as voice radio transmissions. In the United States, a flight operating under IFR is required to provide position reports unless ATC advises a pilot that the plane is in radar contact. The pilot must resume position reports after ATC advises that radar contact has been lost, or that radar services are terminated.
Candidates for the instrument rating must be knowledgeable in IFR-related items in the AIM, the U.S. ATC system and procedures, IFR navigation, the use of IFR charts, aviation weather, requirements for operating under IFR conditions, recognition of critical weather, Aeronautical Decision Making (ADM) and Crew Resource Management (CRM).
While flying VFR-on-top, pilots are required to stay in an appropriate VFR altitude, maintain the required VFR visibility and cloud clearance requirement, while comply with other IFR requirements (minimum IFR altitudes, position reporting, radio communications, course to be flown, adherence to ATC clearance, etc).

Instrument rating refers to the qualifications that a pilot must have in order to fly under instrument flight rules (IFR). It requires specific training and instruction beyond what is required for a private pilot certificate or commercial pilot certificate, including rules and procedures specific to instrument flying, additional instruction in meteorology, and more intensive training in flight ...
If they are not met, the conditions are considered instrument meteorological conditions (IMC), and a flight may only operate under IFR. IFR operations have specific training requirements and certification required of the pilot, and increased equipment requirements for the aircraft. Additionally, an IFR flight plan must usually be filed in advance.
Automatic terminal information service, or ATIS, is a continuous broadcast of recorded aeronautical information in busier terminal areas.ATIS broadcasts contain essential information, such as current weather information, active runways, available approaches, and any other information required by the pilots, such as important NOTAMs.
In the United States, only pilots may initiate a request for this type of approach; regulations prohibit air traffic control (ATC) from asking pilots to perform them. [2] A contact approach will only be issued if the aircraft operates clear of clouds with at least 1 statute mile (1.6 km) of flight visibility, with a reasonable expectation of continuing to the destination airport under those ...
Flight under SVFR is only allowed in controlled airspace, and always requires clearance from air traffic control (ATC). [4] It usually happens when the aircraft is inside controlled airspace, and the local weather is less than the minimums required for flight under visual flight rules (VFR) within the airspace in question.
