IntroductionIs an <strong>Instrument</strong> Rating Necessary?The answer to this question depends entirely upon individualneeds. Pilots who fly in familiar uncongested areas, staycontinually alert to weather developments, and accept analternative to their original plan, may not need an <strong>Instrument</strong>Rating. However, some cross-country destinations may takea pilot to unfamiliar airports and/or through high activity areasin marginal visual or instrument meteorological conditions(IMC). Under these conditions, an <strong>Instrument</strong> Rating may bean alternative to rerouting, rescheduling, or canceling a flight.Many accidents are the result <strong>of</strong> pilots who lack the necessaryskills or equipment to fly in marginal visual meteorologicalconditions (VMC) or IMC conditions and attempt flightwithout outside references.Pilots originally flew aircraft strictly by sight, sound, and feelwhile comparing the aircraft’s attitude to the natural horizon.As aircraft performance increased, pilots required more inflightinformation to enhance the safe operation <strong>of</strong> theiraircraft. This information has ranged from a string tied to awing strut, to development <strong>of</strong> sophisticated electronic flightinformation systems (EFIS) and flight management systems(FMS). Interpretation <strong>of</strong> the instruments and aircraft controlhave advanced from the “one, two, three” or “needle, balland airspeed” system to the use <strong>of</strong> “attitude instrumentflying” techniques.Navigation began by using ground references with deadreckoning and has led to the development <strong>of</strong> electronicnavigation systems. These include the automatic directionfinder (ADF), very-high frequency omnidirectional range(VOR), distance measuring equipment (DME), tactical airnavigation (TACAN), long range navigation (LORAN),global positioning system (GPS), instrument landing system(ILS), microwave landing system (MLS), and inertialnavigation system (INS).Perhaps you want an <strong>Instrument</strong> Rating for the same basicreason you learned to fly in the first place— because you likeflying. Maintaining and extending your pr<strong>of</strong>iciency, once youhave the rating, means less reliance on chance and more onskill and knowledge. Earn the rating—not because you mightneed it sometime, but because it represents achievement andprovides training you will use continually and build upon aslong as you fly. But most importantly—it means greatersafety in flying.<strong>Instrument</strong> Rating RequirementsA Private or Commercial pilot who operates an aircraft usingan instrument flight rules (IFR) flight plan operates inconditions less than the minimums prescribed for visual flightrules (VFR), or in any flight in Class A airspace, must havean <strong>Instrument</strong> Rating and meet the appropriate currencyrequirements.You will need to carefully review the aeronautical knowledgeand experience requirements for the <strong>Instrument</strong> Rating asoutlined in Title 14 <strong>of</strong> the Code <strong>of</strong> Federal Regulations (14CFR) part 61. After completing the <strong>FAA</strong> Knowledge Testissued for the <strong>Instrument</strong> Rating, and all the experiencerequirements have been satisfied, you are eligible to take thepractical test. The regulations specify minimum total and pilotin command time requirements. This minimum applies to allapplicants—regardless <strong>of</strong> ability or previous aviationexperience.Training for the <strong>Instrument</strong> RatingA person who wishes to add the <strong>Instrument</strong> Rating to theirpilot certificate must first make commitments <strong>of</strong> time, money,and quality <strong>of</strong> training. There are many combinations <strong>of</strong>training methods available. Self-study alone may be adequatepreparation to pass the required <strong>FAA</strong> Knowledge Test for the<strong>Instrument</strong> Rating. Occasional periods <strong>of</strong> ground and flightinstruction may provide the skills necessary to pass therequired test. Or, individuals may choose a training facilitythat provides comprehensive aviation education and thetraining necessary to ensure the pilot will pass all the requiredtests and operate safely in the National Airspace System(NAS). The aeronautical knowledge may be administered byeducational institutions, aviation-oriented schools,correspondence courses, and appropriately-rated instructors.Each person must decide for themselves which trainingprogram best meets their needs and at the same time maintaina high quality <strong>of</strong> training. Interested persons should makev
inquiries regarding the available training at nearby airports,training facilities, in aviation publications, and through theFederal Aviation Administration (<strong>FAA</strong>) Flight StandardsDistrict Office (FSDO).Although the regulations specify minimum requirements, theamount <strong>of</strong> instructional time needed is determined not by theregulation, but by the individual’s ability to achieve asatisfactory level <strong>of</strong> pr<strong>of</strong>iciency. A pr<strong>of</strong>essional pilot withdiversified flying experience may easily attain a satisfactorylevel <strong>of</strong> pr<strong>of</strong>iciency in the minimum time required byregulation. Your own time requirements will depend upon avariety <strong>of</strong> factors, including previous flying experience, rate<strong>of</strong> learning, basic ability, frequency <strong>of</strong> flight training, type<strong>of</strong> aircraft flown, quality <strong>of</strong> ground school training, andquality <strong>of</strong> flight instruction, to name a few. The totalinstructional time you will need, and in general the scheduling<strong>of</strong> such time, is up to the individual most qualified to judgeyour pr<strong>of</strong>iciency—the instructor who supervises yourprogress and endorses your record <strong>of</strong> flight training.You can accelerate and enrich much <strong>of</strong> your training byinformal study. An increasing number <strong>of</strong> visual aids andprogrammed instrument courses are available. The bestcourse is one that includes a well-integrated flight and groundschool curriculum. The sequential nature <strong>of</strong> flying requiresthat each element <strong>of</strong> knowledge and skill be learned andapplied in the right manner at the right time.Part <strong>of</strong> your instrument training may utilize a flight simulator,flight training device, or a personal computer-based aviationtraining device (PCATD). This ground-based flight trainingequipment is a valuable tool for developing your instrumentcross-check and learning procedures such as intercepting andtracking, holding patterns, and instrument approaches. Oncethese concepts are fully understood, you can then continuewith in-flight training and refine these techniques for fulltransference <strong>of</strong> your new knowledge and skills.Holding the <strong>Instrument</strong> Rating does not necessarily make youa competent weather pilot. The rating certifies only that youhave complied with the minimum experience requirements,that you can plan and execute a flight under IFR, that youcan execute basic instrument maneuvers, and that you haveshown acceptable skill and judgment in performing theseactivities. Your <strong>Instrument</strong> Rating permits you to fly intoinstrument weather conditions with no previous instrumentweather experience. Your <strong>Instrument</strong> Rating is issued on theassumption that you have the good judgment to avoidsituations beyond your capabilities. The instrument trainingprogram you undertake should help you not only to developessential flying skills but also help you develop the judgmentnecessary to use the skills within your own limits.Regardless <strong>of</strong> the method <strong>of</strong> training selected, the curriculumin appendix 2 provides guidance as to the minimum trainingrequired for the addition <strong>of</strong> an <strong>Instrument</strong> Rating to a Privateor Commercial pilot certificate.Maintaining the <strong>Instrument</strong> RatingOnce you hold the <strong>Instrument</strong> Rating, you may not act as pilotin command under IFR or in weather conditions less than theminimums prescribed for VFR, unless you meet the recentflight experience requirements outlined in part 61. Theseprocedures must be accomplished within the preceding 6months and include six instrument approaches, holdingprocedures, and intercepting and tracking courses through theuse <strong>of</strong> navigation systems. If you do not meet the experiencerequirements during these 6 months, you have another 6months to meet these minimums. If the requirements still arenot met, you must pass an instrument pr<strong>of</strong>iciency check, whichis an in-flight evaluation by a qualified instrument flightinstructor using tasks outlined in the instrument ratingpractical test standards (PTSs).The instrument currency requirements must be accomplishedunder actual or simulated instrument conditions. You may loginstrument flight time during the time for which you controlthe aircraft solely by reference to the instruments. This canbe accomplished by wearing a view-limiting device such asa hood, flying an approved flight-training device, or flyingin actual IMC.It takes only one harrowing experience to clarify thedistinction between minimum practical knowledge and athorough understanding <strong>of</strong> how to apply the procedures andtechniques used in instrument flight. Your instrument trainingis never complete; it is adequate when you have absorbedevery foreseeable detail <strong>of</strong> knowledge and skill to ensure asolution will be available if and when you need it.vi
