What is the difference between CAT II and CAT III?
Comparing Electrical Measurement Categories The higher the short circuit fault current available, the higher the category. While a CAT II rating can be higher voltage than a CAT III rating (say CAT II 1000V vs. CAT III 600V) – the higher CAT rating is almost always the safer rating.
What is a CAT IIIC approach?
The "Cat IIIC" approach is unique in having no minimum "decision height" and no visibility requirement at all. The autopilot takes the plane all the way to the ground, even if the pilots cannot see anything outside their windows.
What is CAT IIIB compliant runway?
With this upgrade, the South Runway can facilitate aircraft landing with a Runway Visual Range as low as 50m and take-offs at 125m. Until now, the permissible visual range was 550m and 300m for landing and take-off, respectively. International Airport Summit 2022: Airports Reimagined.
Why is there no cat 3 C at airport?
c. Category IIIc. A precision instrument approach and landing with no DH and no runway visual range limitation. Right now there is no airport approved for IIIc approaches because the aircraft would just sit on the runway, it has no way of taxiing in.

What is CAT III and CAT IV?
CAT III is for distribution wiring, including main busses, feeders, and branch circuits with permanently installed loads. The highest is CAT IV, which is installation at the origin or at the utility level. Our devices are rated for 600V at CAT IV, for applications between 600 and 750V, they are CAT III rated.
Is RNAV better than ILS?
RNAV approaches are safer and also simpler to use and manage than standard navaids such as VOR's and ILS's, which must be checked for flight under such tolerances. Standard VOR and NDB approaches are removed at most airports in the US and substituted by RNAV approaches.
What is a CAT 1 approach?
Category I (CAT I) Instrument Flight Rules are precision approach runways as defined by FAA and ICAO. Precision Instrument Flight Rules (CAT I) is an operation of precision instrument approach and landing based on the Decision Height (DH) and the Runway Visual Range (RVR).

What is the meaning of cat in aviation?
The term 'commercial air transport (CAT) operation' is defined in Article 3 of Regulation (EU) 2018/1139 as follows: “'Commercial air transport' means an aircraft operation to transport passengers, cargo or mail for remuneration or other valuable consideration.”
What do numbers mean on runways?
Runway numbers are determined by rounding the compass bearing of one runway end to the nearest 10 degrees and truncating the last digit, meaning runways are numbered from 1 to 36—as per the diagram below. The opposite end of the runway always differs by 180 degrees, so it's numbered 18 higher or lower.

What is a CAT III?
A higher CAT number refers to an electrical environment with higher power available and higher energy transients. Within a category, a higher voltage rating denotes a higher transient withstand rating, e.g., a CAT III -1000 V meter has superior protection compared to a CAT III -600 V rated meter.
What is the difference between CAT I and CAT II?
On larger aircraft, these approaches typically are controlled by the flight control system with the flight crew providing supervision. CAT I relies only on altimeter indications for decision height, whereas CAT II and CAT III approaches use radio altimeter (RA) to determine decision height.
What does Cat 3 mean on a multimeter?
A higher CAT number refers to an electrical environment with higher power available and higher energy transients. Thus, a multimeter designed to a CAT III standard is resistant to much higher energy transients than one designed to CAT II standards.

Category II Pilot Authorization: A part of the holder’s instrument rating or airline transport pilot certificate (but separately issued) that authorizes the holder to conduct Cate- gory II operations as pilot in command of specified types of airplanes.
Is DME required for ILS?
No, a DME is not required for all ILS approaches; however, there are some ILS / DME approaches that require it. Normally it’s because they have an arc or the distance is needed to locate a fix on the approach.
Why Tools Are Certified with Electrical Measurement Categories
Before looking into the various categories it’s important to understand exactly why tools are certified in particular ways. First off, when dealing with electricity, you MUST understand that the tool is either designed for a particular application or not.
Comparing Electrical Measurement Categories
In a nutshell, the higher the electrical measurement category, the more risk there is of what’s known as an “arc blast” – a situation where high voltage can overload a circuit and cause electrical (and physical) damage. Arc blast can ruin your whole day… or life. The higher the short circuit fault current available, the higher the category.
Certifications and Standards
IEC sets standards but it doesn’t test or enforce industry or product-level compliance. As a result, a manufacturer can claim to “design to” a standard but have nothing in place that substantiates their claims.
What is Instrument Landing System (ILS)?
ILS is a guidance system that helps planes land in low visibility conditions with the help of radio signals and also sometimes high-intensity lighting arrays. The Delhi airport has been equipped with the CAT IIIB system (short for category 3) which is operating on three runways.
Why the Delay?
Many a times it’s not the absence of pilots or the technology that is the problem. A lot of financial and logistical constraints too play a part in flight cancellation and delays due to fog. BJP lawmaker and party general secretary Ram Madhav realised this during his recent visit to the Delhi airport.
What is CAT IIIB certification?
Acquiring CAT IIIB certification requires the airline provider’s fleet to be equipped with the technology and have trained pilots to operate that tech. Flights which are not CAT IIIB compliant do not operate in regions where fog or low visibility is expected.

What are the factors that have to be considered for the CAT IIIB system to work at its optimum efficiency?
The three factors that have to be considered for the CAT IIIB system to work at its optimum efficiency are — training of pilots and co-pilots on the system, cockpit (aircraft) compliance and airport compliance. Sadly, that’s not the case in India.
How far away is a CAT IIIB?
A CAT IIIB system helps with a precision approach and landing when the runway visibility is at a distance no less than 50 feet (15m) and is at a visual range less than 200 meters and most certainly not less than 50 metres. The whole process is automated. There is a voice that prompts (via a countdown) how far the plane is away from the runway, when the flaps have to be deployed and subsequently when the brakes have to be applied.
Which airports use CAT IIIC?
There are only a few airports that use this tech including New York’s JFK International Airport and the Heathrow airport in London. ADVERTISEMENT.
