  1. Introduction

The following report aims to assess the performance characteristics of the Jetstream HP137 Mk 1. The aircraft is operated by the College of Aeronautics.

I suppose something needs to be said here!


  1. Methodology

The aircraft performance data was provided in the form of graphs which were produced and collated between the seven groups, from the data that was recorded in the Jetstream. These interim performance charts are found in Appendix A. In addition to this, fuel flow data was recorded during taxi, approach and take-off.

2.1        Performance Summary Tables

The objective is to calculate the range and time taken to complete a mission with a given amount fuel and payload. Each mission is split into 2 main parts – the ‘en-route’ and the ‘diversion’. Each phase (ie climb, cruise, descent, etc) is operated in a certain way and relevant parameters such as climb rates and cruise altitudes are usually stipulated by company policy. Using the data available in the fuel flow tables and interim performance charts, fuel burn for each phase of the flight was calculated.

The fuel, time and distance required for each stage are calculated as described above and entered into the table in a systematic manner – starting with the ramp weight of the aircraft and proceeding through the mission profile. A column is dedicated to monitoring the decrease in aircraft weight. This is balanced by the increase in fuel consumed.

The analysis was performed at the following combination of payload and fuel on board to define the range payload diagram:

Point 2: Take-off at MTOW, comprising maximum payload and remaining fuel allowable

Point 3: Take-off at MTOW, comprising maximum fuel and remaining payload allowable

Point 4: Take-off weight the sum of OEW and MFW

When all flight phases are calculated, the sum of the fuel burn, time taken and distance covered is calculated. The distance and time contributions are taken only for those phases that fall under the en-route mission, while the fuel required to perform the en-route and diversion are calculated separately and summed.

2.2        Strategy Adopted

Overall guidelines were followed in the form of rounding the results for fuel as to give a conservative figure.

For all the diversion stages the priority was to minimise fuel burn. This was achieved by comparing the fuel burn for different climb speeds ...
