FAQs
The standards give the following utilisation categories: AC-21 – Switching of resistive loads including moderate overloads. AC-22 – Switching of mixed loads, inductive and resistive loads including moderate overloads. AC-23 – Switching of motor loads or other highly inductive loads.
What is FAA part 23? ›
Under current 14 CFR Part 23, airplanes are certified in one or more of the following categories: normal, utility, acrobatic, and commuter. Classification primarily depends upon the types of maneuvers to be performed, number of seats, number of engines, and maximum certificated takeoff weight.
What is the FAA definition of equipment? ›

Is 23 degrees good for AC? ›
The Ideal Air Conditioner Temperature Setting Is 22-26°C
Not too hot, not too cold, but just right. Studies have shown that for each degree you raise your thermostat, you can save 3-5% on cooling costs. You need to find the sweet spot between saving and staying cool.
What does AC mean in the Bible? ›
IIRC AC, which is seldom used, is “ante Christum”, before Christ.
What is the difference between FAA Part 23 and 25? ›
Part 23 aircraft are defined as normal, utility, acrobatic, and commuter category airplanes; Part 25 defines transport category airplanes. The discussions in this section are applicable to Part 27 (utility helicopters) and Part 29 (transport helicopters) as well as military installations.
What is the weight limit for FAA Part 23? ›
(a) Certification in the normal category applies to airplanes with a passenger-seating configuration of 19 or less and a maximum certificated takeoff weight of 19,000 pounds or less.
What is the FAA Part 23 rewrite? ›
The FAA has released a final rule that reforms small aircraft certification standards with groundbreaking new provisions that allow manufacturers to use performance-based, industry-consensus standards in place of the “prescriptive” manufacturing methods that have long hindered development of new designs and ...
What is a part 25 aircraft? ›
What types of aircraft are certified under CFR Part 25? The airworthiness standards outlined in CFR Part 25 apply to aircraft in the transport category. The term “transport,” widely used by aviation regulatory bodies in the U.S., Canada, and Europe, is typically used to describe large civil airplanes or helicopters.
What was the FAA called before it was the FAA? ›
The FAA was created in August 1958 as the Federal Aviation Agency, replacing the Civil Aeronautics Administration (CAA). In 1967, the FAA became part of the newly formed U.S. Department of Transportation and was renamed the Federal Aviation Administration.
⦁ V1 —critical engine failure speed or takeoff decision speed. It is the speed at which the pilot is to continue. the takeoff in the event of an engine failure or other serious emergency. At speeds less than V1, it is. considered safer to stop the aircraft within the accelerate-stop distance.
What does AC mean in numbers? ›
Most people don't know what comes after trillion, either because they never looked it up, or they don't have any application for numbers that high. aa = quadrillion, 10^15. ab = quintillion, 10^18. ac = sextillion, 10^21.
What does AC mean in code? ›
Arithmetic coding (AC) is a form of entropy encoding used in lossless data compression. Normally, a string of characters is represented using a fixed number of bits per character, as in the ASCII code.
What is the meaning of AC23? ›
What does AC22, AC23 mean? These numbers are the "Utilization category" derived from the IEC 60947 standard. AC22 - switching of mixed resistive and inductive loads including moderate overloads. AC23 - switching of motor loads or other highly inductive loads.
