The Fight Times Saga continues in this second installment with even more unexplained paranormal events and divine interventions. More laughs, romance, hysterical and sometimes even shocking encounters ahead. It follows Stan and his group of friends on their next chapter after the demise of Festival Airways with new adventures at Universal Airlines. There are more twist and turns for this group of friends as they continue to Jet through the 90's and the millennium year 2000. The book takes you through their perspective from the inside of the tragic and highly suspicious events of Sept 11th. It is now time to recline your seat, sit back and relax. As we have now reached our comfortable ""Cruising Altitude"" for today's flight.

Aircraft Cruise Phase Altitude Optimization Considering Contrail Avoidance written by Hang Gao (S.M.) and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2013 with categories.

Contrails have been suggested as one of the main contributors to aviation-induced climate impact in recent years. To reduce the climate impact of contrails, mitigation policies such as taxation will be necessary in the future to incentivize jet aircraft operators to reduce contrail production. Contrails form in regions of the atmosphere with the right ambient conditions and they can be avoided by flying around these regions; this research investigates one such contrail avoidance strategy that uses flight level optimization to minimize contrail formation. A cruise phase flight profile system model was developed in this research that optimizes for environmental objectives such as contrails, CO2, and NOx, alongside traditional objectives such as fuelburn and flight time. Using this system model and 11 different aircraft types on 12 weather days, a preliminary study was done to determine the price range of contrail taxation that would incentivize airlines to operationally avoid contrails. Result suggests a price range of 0.12$/NM to 1.13$/NM on contrail tax would effectively incentivize contrail avoidance. Furthermore, since operating costs differ depending on the type of aircraft, a single price on contrail tax may incentivize contrail avoidance on a small aircraft, but not larger ones. To account for this difference, a method of assigning contrail tax to different aircraft types is introduced using the aircraft maximum takeoff weight. Assuming airlines are incentivized to fly contrail avoidance strategies, the climate impact of the flight profiles was evaluated for 287 flights along 12 O-D pairs for the 24 hour day of April 12, 2010. Under various assumptions of contrail radiative forcing and time horizon of climate impact evaluation, the flight level optimization reduced the average climate impact per flight by as much as 39.1% from a baseline of wind-optimal flight at optimal cruise altitude. In comparison, a complementary lateral optimization method reduced 13.3% from the same baseline. Furthermore, flight level optimization shows to be more fuel efficient by reducing the climate impact of contrails by as much as 94% from the baseline, compared to 60% using the lateral approach. In terms of the CO2 emission from the additional fuelburn, the climate impact of lateral method was 4 times higher than the flight level approach. Lastly, result shows that designing for long-term environmental objectives is more energy efficient (reduction in climate impact per additional kilogram of fuel used) than short-term, which suggest reducing CO2 emission is favored over contrail avoidance in designing for climate impact optimal flight profiles.

Jensen and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2014 with categories.

This study examines the potential fuel burn benefits of altitude and speed optimization in the cruise phase of flight for domestic airlines in the United States. Airlines can achieve cost reductions and reduce environmental impact by making small modifications to the cruise phase operating condition. With strong coordination between air traffic controllers, pilots, and airline dispatchers, the efficiency of the National Airspace System can be improved. This study builds off of prior work in this area to establish best-case benefits assuming full implementation of fuel-optimal cruise altitudes and speeds. In order to achieve these objectives, a cruise-phase fuel burn estimator is developed using publicly-available radar tracks and weather data. This estimator is used to examine over 200,000 flights from 2012 for optimization potential. Maximum benefits from altitude optimization (holding speed constant) are found to be on the order 1.96% cruise fuel reduction. The incremental benefit of highfidelity trajectory optimization relative to well-designed step climb profiles indicates that the majority of potential altitude benefits can be achieved through efficient application of today's airspace structure and procedures. The maximum benefits for speed optimization (holding altitude constant) are found to be 1.94% with an average flight time increase of 3.5 minutes per flight. Simultaneous altitude and speed optimization yield a potential cruise fuel burn reduction of 3.71%. In practice, operational considerations and barriers to implementation limit likely system fuel reduction to lower levels. High-benefit operations within the NAS are identified and potential implementation considerations are discussed.
