<br />ANNEX A <br /> <br />NOAA Aircraft Operations Center <br />Project Instructions <br />NOAA/Utah Atmospheric Measuring Program <br /> <br />24 November 1993 <br /> <br />GENERAL: King Air N46RF will support the NOAA/Utah Atmospheric Measuring Program (NUAMP) as <br />an air sampling platfofDl. Approximately 60 project flight hours are anticipated between January 15,1993 and <br />March 15, 1993. The scientific objectives of the program are as follows: <br /> <br />The primary purpose of the early 1994 field program will be to directly detect, by physical measurements, the <br />effects of propane and AgI seeding from high altitude ground sites. Secondary purposes will be to expand <br />examination and understanding of SLW distributions over the Wasatch Plateau (Plateau), and to determine the <br />warmest orographic cloud temperatures at which significant ice particle concentrations (IPC) result from AgI <br />seeding. <br /> <br />OPERATIONS: The project will be flown from Provo municipal airport, Provo, Utah. Three trackIines will <br />be flown at various altitudes. The trackline end and turn points are described in attachment a of these <br />instructions. this sampling will be done in both instrument meteorological conditions (IMC) and visual <br />meteorological conditions (YMC). <br /> <br />ALTITUDES: The tracklines will be flown at various altitudes beginning on a higher altitude trackIine and flying <br />progressively lower tracklines. The starting tracklines for each day will not be flown below the TrackIine Safety <br />Altitude (TSA). (For purposes of this discussion, the TSA is defined as 2000 feet above the highest terrain <br />within 10 NM of the course to be flown). If any trackline is to be flown below the TSA, then it must have been <br />flown at least once that day at an altitude higher than the TSA. <br /> <br />The altitudes of the lower lines will vary along the lines to maintain no less than 1000 feet AGL. No IFR <br />operations will be conducted at less than 1000 feet AGL. If a certain portion (segment) of a line is to be reflown <br />to, study the plume, extreme caution wiU be exercised to not operate IFR with less than 1000 feet ground <br />clearance along the segment or in the turns. <br /> <br />COURSE REVERSALS BELOW TSA: IMC course reversals or trackIine departures in the middle of a <br />trackIine will be handled only in accordance with planned and previously practiced VFR procedures. <br /> <br />Course reversals at the end of tracklines will be standardized maneuvers fully practiced in VFR conditions. <br /> <br />Tracklines may need to be flown in one direction only with no course reversals. This will be determined by the <br />PIC prior to executing any trackline IMC. <br /> <br />SAFETY: Flying the trackIines at the requested lower altitudes is a hazardous operation, tolerant of only small <br />deviations from trackline and of no mistakes in maintaining proper altitude for the segment of the trackline. <br /> <br />Any flight crew confusion as to proper navigation on the trackIine will warrant immediate emergency departure <br />from the trackline and the mountainous area. <br /> <br />GPS is not certified for IFR use and will be used only for emergency navigation information if the certified <br />navigation equipment fails. <br /> <br />Loss of VOR, DME and ANI 7000 LORAN data will call for immediate departure from the trackline and <br />mountainous area. The flight crew should keep in mind, at all times, the escape route from the mountains for <br />all segments of trackline. <br /> <br />1 <br />
