The LTO cycle (Landing and Take-off cycle) is a research method used for jet engines certification. The measurements are performed in stationary conditions. With the development of aviation, the LTO test started to be carried out more often, but not for its’ original purpose. A new aim was an assessment impact of aircraft movement on environment in airports area. LTO cycle consists of four phases (according to ICAO Annex 16): take-off, climb out, approach and taxi/idle. Every airport has different infrastructure, what affects on time during basic flight operations especially for a taxi phase. To rate exhaust emission from aircrafts during basic fly operations duration time should be adjusted to every single airport. As a research area Poznań-Ławica Airport which is located in Poland, was adopted. Based on parameters calculated specially for this airport it is possible to computed there emission from the mostly used aircraft.

Analysis of the impact of wind on fuel consumption and emissions of harmful exhaust gas compounds on the selected flight route

R. 58, nr 4

The article discusses the issue of the impact of wind force and direction on fuel consumption and the emission of harmful exhaust gases on the selected flight route. The focus was on percentage changes in fuel consumption and emissions of individual harmful exhaust gas compounds depending on the wind speed and the direction from which it interacts with the aircraft. The analysis was carried out for three different flight levels, in order to compare changes in fuel consumption and emissions also in terms of flight altitude, however the following article focuses only on one level - FL240.

Analysis of the ecological effectiveness of passenger transport by jets of various sizes

The article’s aim was to compare an ecological effectiveness of a common jetliner with 189 passenger capacity flying on two CFM engines and a very light jet business aircraft designed to carry up to 8 people on board. The carried-out analysis showed that the NOx emission per passenger in Very Light Jet (VLJ) is three times higher than in common jet airliner, furthermore there is 15 times difference in CO emission. Based on the results of the analysis, it can be stated that it is appropriate to extend the certification of engines to smaller units, as well as to adjust the LTO test beyond laboratory conditions.
