Guidance concerning Air Navigation in and above the NAT MNPSA CHAPTER 1data. To minimize the problem, source data must be clearly legible under the worst cockpit lightingconditions. More detailed recommendations are included in Chapter 8 of this Document.Crew Training1.3.6 It is essential that crews obtain proper training for MNPS and RVSM operations. Currentnavigation systems, because of their precision and reliability, can induce a sense of complacency, which inturn tends to obscure the value of standard procedures, and in particular of cross-checks. Under thesecircumstances errors occur more easily. To prevent them, a special training programme for flight crewsshould be devised, which includes instructions on the efficient use of equipment, with emphasis on how toavoid mistakes. Crew members should be trained to develop a meticulous method of using Control DisplayUnits (CDUs), with careful cross-checking at all operational stages, in line with procedures described inChapter 8 of this Document.1.3.7 The Operator should thereafter seek to retain the interest and co-operation of flight crews byensuring that a high standard of navigation performance be maintained. This may be achieved during groundrefresher courses, routine checks, or/and by issuing periodic newsletters that include a focus on fleetnavigation performance - hopefully indicating that standards are being maintained or are being improvedupon. Newsletters might also include analyses of error reports volunteered by crews (i.e. covering instancesof equipment being mishandled). However, periodic reminders should not be so frequent as to be selfdefeating.1.3.8 Crew training should stress the need for maintaining accuracy along and across track (i.e. thecareful application of Mach Number Technique, accurate reporting of positions and the use of accurate timein reporting positions).1.3.9 The following items should also be stressed in flight crew training programmes:a) knowledge and understanding of standard ATC phraseology used in each area of operations;b) importance of crew members cross-checking each other to ensure that ATC clearances arepromptly and correctly complied with;c) use and limitations, in terms of accuracy, of standby altimeters during contingencysituations. Where applicable, the pilot should review the application of Static Source ErrorCorrection/Position Error Correction (SSEC/PEC) through the use of correction cards;d) characteristics of aircraft altitude capture systems which may lead to the occurrence ofovershoots;e) relationships between the altimetry, automatic altitude control and transponder systems innormal and abnormal situations; andf) aircraft operating restrictions related to airworthiness approval.1.3.10 Finally, crew training should be extended to include instruction on what action should beconsidered in the event of systems failures. Chapter 11 of this Document provides assistance in establishingsuch action.NAT Doc 007 5 Edition 2010
