Unmanned aircraft present unique challenges for applicants and examiners. Unlike manned aircraft, in which, regardless of the size and complexity of the aircraft, there are still basic similarities in concepts and operations, unmanned aircraft are varied in both flight capability and pilot interaction. Many aspects of unmanned aircraft operations are automated, and the pilots may not have the same information available to them (that is, pitch and bank) that pilots flying manned aircraft have available to them. This will create a situation in which some unmanned aircraft systems (UAS) will not be capable of meeting all the requirements of this practice or will not require the same skill sets that manned aircraft require.The examiner will have to decide which tasks the applicant's UAS will be capable of completing and test those tasks. As required, the examiner will note any limitations as a result of the UAS being incapable of performing a task on the applicant's certificate per 14 CFR 61.45(b)(2). If the applicant desires to have a certificate with no restrictions or limitations, he/she will need to use a UAS that is capable of completing all the tasks in this practice.Information considered directive in nature is described in this practice by the use of “shall” and “must” indicating the actions are mandatory. Guidance information is described in terms such as “should” and “may” indicating the actions are desirable or permissive but not mandatory. A list of acronyms is in Section 3.This practice includes the areas of operation and tasks that will demonstrate the pilot's ability to fly the unmanned aircraft safely and proficiently.1.1 This practice defines the knowledge, skills, and abilities required of unmanned aircraft pilots to be able to fly unmanned aircraft—single-engine land (SEL) in the national airspace system safely and for hire.1.2 The commercial unmanned aircraft systems (UAS) pilot practical test standards (PTS)-unmanned aircraft include the areas of operation and tasks that will demonstrate the pilot's ability to fly the unmanned aircraft safely and proficiently.1.3 This practice does not apply to pilots who will fly mini/small unmanned aerial vehicles (UAVs) for hire within visual range of the pilot, mini/small UAVs being those UAVs listed as lightly regulated.1.4 This practice provides a PTS intended to meet the Civil Aviation Authority’s (CAA) requirements for issuing commercial UAS pilot authorizations.1.5 The values given in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5.1 This guide is intended to provide machinery maintenance and monitoring personnel with a guideline for performing trend analysis to aid in the interpretation of machinery condition data.1.1 This guide covers practical techniques for condition data trend analysis.1.2 The techniques may be utilized for all instrumentation that provides numerical test results. This guide is written specifically for data obtained from lubricant samples. Other data obtained and associated with the machine may also be used in determining the machine condition.1.3 This guide provides a methodology for assessing changes in lubricant during service. For limits on a specific lubricant parameter used in different system types, users should refer to Practice D4378, Practice D6224, or other established industry criteria, such as from the OEM. Guide D7720 may be used to determine limits if unavailable through the other references given.1.4 This guide does not address upper or lower control limits. These limits are provided by product manufacturers, defined in ASTM specifications, or both. The range between upper and lower control limits should be greater than the range within each test method’s repeatability coefficient. See Practices D3244, D6299, and D6792 for more information about ensuring that process control limits do not violate statistical fundamentals.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Interior architectural paints are subjected in use to soiling by dirt or other stains. This test method provides a way to assess relative ease of soil or stain removal from a paint film using materials common to households. This test method includes a way to evaluate the film for washability properties and changes in appearance. Thus, a formulator may evaluate the effects of composition on the washability properties of a paint. Users may also compare the ease of soil removal from different paints that are tested, preferably at the same time.1.1 These test methods cover the determination of the relative ease of removal of common soil and stains from interior coatings by manual or mechanical washing with a sponge and a liquid or powder cleanser.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
