| 3.13 Crew Training 3.13.1 It is essential that crews obtain proper training for MNPS and RVSM operations. Current navigation systems, because of their precision and reliability, can induce a sense of complacency, which in turn tends to obscure the value of standard procedures, and in particular of crosschecks. Under these circumstances errors occur more easily. To prevent them, a special training programme for flight crews should be devised, which includes instructions on the efficient use of equipment, with emphasis on how to avoid mistakes. Crew members should be trained to develop a meticulous method of using Control Display Units (CDUs), with careful crosschecking at all operational stages, inline with procedures described in the “NAT MNPS Airspace Operations Manual”. 3.13.2 The Operator should thereafter seek to retain the interest and cooperation of flight crews by ensuring that a high standard of navigation performance be maintained. This maybe achieved during ground refresher courses, routine checks, or/and by issuing periodic newsletters that include a focus on fleet navigation performance - hopefully indicating that standards are being maintained or are being improved upon. Newsletters might also include analyses of error reports volunteered by crews (i.e. covering instances North Atlantic Guidance Material 3-9 7 th Edition of equipment being mishandled. However, periodic reminders should not be so frequent as to be self- defeating. 3.13.3 Crew training should stress the need for maintaining accuracy along and across track (i.e. the careful application of Mach Number Technique, accurate reporting of positions and the use of accurate time in reporting positions. 3.13.4 The types of navigation systems presented herewith their computers and related displays, provide the ability to fly direct Great Circle routes. This feature can be attractive and useful to crews, and they need not be discouraged from taking advantage of it. However, during initial and refresher training, Operators should point out to crews that firstly, it is necessary to obtain an ATC clearance for such routes and, secondly, that the wind effect maybe such that the Great Circle path is far from being the minimum time path (the most fuel economical route. Finally, if not properly cleared by ATC, there maybe a risk of the aircraft inadvertently entering restricted airspace or crossing political boundaries, without authority. 3.13.5 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 crosschecking each other to ensure that ATC clearances are promptly and correctly complied with c) use and limitations, in terms of accuracy, of standby altimeters during contingency situations. Where applicable, the pilot should review the application of Static Source Error Correction/Position Error Correction (SSEC/PEC) through the use of correction cards d) characteristics of aircraft altitude capture systems which may lead to the occurrence of overshoots e) relationships between the altimetry, automatic altitude control and transponder systems in normal and abnormal situations and f) aircraft operating restrictions related to airworthiness approval. 3.13.6 Finally, crew training should be extended to include instruction on what action should be considered in the event of systems failures. The “NAT MNPS Airspace Operations Manual” provides useful assistance in establishing such action. Download 0.84 Mb. Share with your friends:
