Performance in Flight Planning
In a computerised flight planning system, in-flight performance data supplied by the manufacturer is stored in the computer database, either in tables, graphs or formulae. This data is then used in creating the flight plan for a particular flight, using a particular routing and aircraft weight, under the applicable en route weather conditions. Basic performance criteria for each aircraft includes cruise, climb and descent data for various flight levels, weights and ambient temperatures, and optimum and maximum altitude limits. Climb, cruise and descent phases of each flight are evaluated separately by the system. Ambient weather conditions, such as forecast wind and temperature aloft, are applied to calculate fuel requirements and elapsed time. The Operations Officer or pilot creating the flight plan can specify various performance related factors and make any changes he considers necessary for that flight in the interests of safety, passenger comfort or service. Exercise 2.5.2 Answer the questions. 1. Where are Structural Weight Limitations published? 2. What are basic RTOW tables and graphs produced for? 3. What are the particular factors that apply to an airfield and to the airfield runways? 4. What does TORA (TODA, ASDA) stand for? 5. What are navigation charts? 6. Why are special procedures applied for takeoff and landing on wet or contaminated runways? 7. What does basic performance criteria include? Exercise 2.5.3 Are the sentences true (v) or false (x)? Correct the false ones. 1. Structural weight limitations are published in the Flight Manual. 2. Factors such as take off thrust are varied to reduce engine stress. 3. Special procedures are not applied for the takeoff and landing on wet or contaminated runways. 4. Noise abatement procedures are in operation in many airports. 5.

Section 2.6 The Flight Plan Exercise 2.6.1 Read and translate the text. A computer Flight Planning System constructs the operating flight plan for a particular flight. It: · creates required routes and tracks; · analyses en-route weather data received for the relevant PROGS, and combines this with detailed route and navigation data for the routings, to produce accurate information on which flight plan calculations are based; · uses aircraft performance data for the particular aircraft registration or tail number, together with required TOW or ZFW, flight levels, and other specific details for the flight. The principle benefit lies in more accurate flight planning. The speed and ease with which plans can be produced means more flexible utilization by flight planners of the parameters in the flight plan, resulting in more accurate burn-off calculations, with consequent fuel saving and many other benefits. Waypoints on the flight plan are often defined by a name, and referenced by latitude and longitude. Airports and en-route checkpoints are typical waypoints which have allocated names. Other waypoint names are simply a restatement of the latitude and longitude, e.g., Oceanic waypoints. Information for each waypoint is stored on the computer system for inclusion in flight plans. Waypoint co-ordinates for each waypoint, navigational frequencies, MSAs and other information for the route are stored on a database. Updated information is included in any relevant flight plan. Performance data may be accessed by performance type, by fleet type or by aircraft registration, allowing precise tailoring of performance data for individual aircraft registrations. Basic performance data include climb, cruise, descent data, and altitude limits. The computer generated flight plan is representative of the general format employed throughout the industry. The operational flight plan combines navigation information, en-route weather data and aircraft performance data, together with planned payload, flight levels, alternates, holding fuel, and other specific details for the flight. It includes the navigation log. Performance data for flight planning is tailored for each individual aircraft. It includes climb, cruise, and descent data for the trip to destination as well as the alternate routes. It also includes altitude limits, contingency fuels and various constants and default maximum weights, taxi fuel flow, holding time, waypoint details, fuel carriage saving information and many other details essential to the pilot during flight. An airline operational flight plan contains features common to all such plans. The actual terms and abbreviations used, their position on the plan and the general lay-out may vary. For example, additional information is provided for long distance and ETOPS flight plans. There are spaces provided on the plan under the headings AREM, ETA, ATA and FL where the pilot fills in actual navigation and performance details as the flight progresses. The completed flight plan, which is the official record of the progress of the flight, must be retained for inspection for a minimum of six months. Exercise 2.6.3 Answer the questions. 1. What does a computer Flight Planning System do? 2. What does it also analyze? 3. What are the weather data received for? 4. What is the principle benefit of this system? 5. How are the waypoints usually defined? 6. What are oceanic waypoints characterized by? 7. Where is the information for each waypoint stored? 8. What is the updated information included in? 9.

It creates required routes and tracks, but it does not analyze any en-route weather data. 3. The system uses aircraft performance data for the particular aircraft registration or tail number. 4. The principle benefit lies in a quicker flight planning process. 5. The speed and ease with which plans can be produced means more rigid utilization of the parameters in the flight plan. 6. It results in more accurate burn-off calculations, with consequent fuel saving and many other benefits. 7. Waypoints on the flight plan are always defined by a name, and referenced by latitude and longitude. 8. Airports and en-route checkpoints are typical waypoints which have allocated names. 9. Information for each waypoint is stored on the computer system for further inspection. 10. Updated information is excluded from relevant flight plans. 11.
