Using the latest microchip and display technologies, the CX-3 features make it the most versatile and useful aviation calculator available . May be used during FAA and Canadian Ergonomic design. The CX-3 features a simple Knowledge Exams. The CX-3 complies with FAA keyboard and slim design . The non-slip cover will Order 8080 .6 and Advisory Circular (AC) 60-11, “Test protect your computer inside the flight bag and it fits Aids and Materials that May be Used by Airman on the backside of the unit for easy storage while in Knowledge Testing Applicants”; therefore you may use . bring the CX-3 with you to the testing centers for all Unit conversions. The CX-3 has 12 unit- pilot, mechanic, and dispatcher FAA exams . conversions: Distance, Speed, Duration, Numerous aviation functions. You can calculate Temperature, Pressure, Volume, Rate, Weight, Rate everything from true airspeed and Mach number, of Climb/Descent, Angle of Climb/Descent, Torque, fuel burn, holding patterns, to headwind/crosswind and Angle . These 12 conversion categories contain components, center of gravity (CG), and everything 38 different conversion units for over 100 functions . in between . The menu structure provides easy entry, Timers and clocks. The CX-3 has two timers: a review, and editing within each function . Multiple stopwatch that counts up and a countdown timer . problems can be solved within one function . The stopwatch can be used to keep track of elapsed User-friendly. The color LCD screen displays a time or to determine the time required to fly a known menu of functions and the inputs and outputs of a distance . The countdown timer can be used as a selected function, for easy-to-read menus and data reminder to switch fuel tanks, or to determine the displays . The inputs and outputs of each function missed approach point on a non-precision instrument are separated on the display screen so it is clear approach . An internal clock continues running even which numbers were entered and which were when the flight computer is turned off . UTC and local calculated, along with their corresponding units of time can be displayed, and the time can be set with measurement . The menu organization reflects how UTC, destination or local time . a flight is normally planned and executed . The result Interactive functions. The CX-3 is designed so is a natural flow from one function to the next with a the functions can be used together . You can perform minimum of keystrokes: to plan a flight, simply work “chain” calculations where the answer to a preceding from the menus in sequential order as you fill in your problem is automatically entered in subsequent flight plan form . problems .

  • The Difference Between Higher and Lower Flap Setting Configurations May Seem Small, but at Today's Fuel Prices the Savings Can Be Substantial
    THE DIFFERENCE BETWEEN HIGHER AND LOWER FLAP SETTING CONFIGURATIONS MAY SEEM SMALL, BUT AT TODAY'S FUEL PRICES THE SAVINGS CAN BE SUBSTANTIAL. 24 AERO QUARTERLY QTR_04 | 08 Fuel Conservation Strategies: Takeoff and Climb By William Roberson, Senior Safety Pilot, Flight Operations; and James A. Johns, Flight Operations Engineer, Flight Operations Engineering This article is the third in a series exploring fuel conservation strategies. Every takeoff is an opportunity to save fuel. If each takeoff and climb is performed efficiently, an airline can realize significant savings over time. But what constitutes an efficient takeoff? How should a climb be executed for maximum fuel savings? The most efficient flights actually begin long before the airplane is cleared for takeoff.

  • 16.00 Introduction to Aerospace and Design Problem Set #3 AIRCRAFT
    16.00 Introduction to Aerospace and Design Problem Set #3 AIRCRAFT PERFORMANCE FLIGHT SIMULATION LAB Note: You may work with one partner while actually flying the flight simulator and collecting data. Your write-up must be done individually. You can do this problem set at home or using one of the simulator computers. There are only a few simulator computers in the lab area, so not leave this problem to the last minute. To save time, please read through this handout completely before coming to the lab to fly the simulator. Objectives At the end of this problem set, you should be able to: • Take off and fly basic maneuvers using the flight simulator, and describe the relationships between the control yoke and the control surface movements on the aircraft. • Describe pitch - airspeed - vertical speed relationships in gliding performance. • Explain the difference between indicated and true airspeed. • Record and plot airspeed and vertical speed data from steady-state flight conditions. • Derive lift and drag coefficients based on empirical aircraft performance data. Discussion In this lab exercise, you will use Microsoft Flight Simulator 2000/2002 to become more familiar with aircraft control and performance. Also, you will use the flight simulator to collect aircraft performance data just as it is done for a real aircraft. From your data you will be able to deduce performance parameters such as the parasite drag coefficient and L/D ratio. Aircraft performance depends on the interplay of several variables: airspeed, power setting from the engine, pitch angle, vertical speed, angle of attack, and flight path angle.

  • Chapter: 4. Approaches
    Chapter 4 Approaches Introduction This chapter discusses general planning and conduct of instrument approaches by pilots operating under Title 14 of the Code of Federal Regulations (14 CFR) Parts 91,121, 125, and 135. The operations specifications (OpSpecs), standard operating procedures (SOPs), and any other FAA- approved documents for each commercial operator are the final authorities for individual authorizations and limitations as they relate to instrument approaches. While coverage of the various authorizations and approach limitations for all operators is beyond the scope of this chapter, an attempt is made to give examples from generic manuals where it is appropriate. 4-1 Approach Planning within the framework of each specific air carrier’s OpSpecs, or Part 91. Depending on speed of the aircraft, availability of weather information, and the complexity of the approach procedure Weather Considerations or special terrain avoidance procedures for the airport of intended landing, the in-flight planning phase of an Weather conditions at the field of intended landing dictate instrument approach can begin as far as 100-200 NM from whether flight crews need to plan for an instrument the destination. Some of the approach planning should approach and, in many cases, determine which approaches be accomplished during preflight. In general, there are can be used, or if an approach can even be attempted. The five steps that most operators incorporate into their flight gathering of weather information should be one of the first standards manuals for the in-flight planning phase of an steps taken during the approach-planning phase.

  • Altimetry for Mountaineers and Hikers a Brief Summary
    Altimetry for Mountaineers and Hikers A brief summary • Understanding Altimetry How changes in weather can affect your pressure altimeter. How elevation effects your pressure altimeter How air temperature effects air density and your climbing performance By: Derek Taylor . WTS Senior Instructor . BMS Assistant Instructor . Aerosciences, Lockheed Martin Astronautics . Certified Flight Instructor (MEI, CFII) Altimetry – Why is Altimetry Important? You need to understand how to use an altimeter, but also what factors can effect its accuracy. Good mountaineering /hiking practice usually requires the use of an altimeter. Topography and Contour maps are very limited without knowing what your “correct” elevation is. A map & compass provides you with information about where you are horizontally. If you know exactly where you are on a map then you can determine your elevation. But an altimeter can “directly” provide you with elevation. Since we move about in a 3-dimenisonal world, then knowing how to use an altimeter, and what its limitations are, is just as important as knowing how to use a compass. – With an Altimeter you can Perform Bearing-Elevation Intersects: The point at which a compass bearing intersects an elevation contour line. Use your compass and altimeter collectively to locate your position. Perform Feature-Elevation Intersects: The point at which a known feature, such as a creek, road, or ridge intersects your known elevation. Use your altimeter/barometer to predict weather changes. High pressure systems are generally associated with stable, dry weather. Low pressure systems are the predictors of possible rain, snow, thunder activity, and cooler temperatures. Use your altimeter to estimate elevation gain per hour, and adjust your pace accordingly.
