Document Summary
The actual overall range of a fixed-wing aircraft will include mission components such as takeoff, climb to altitude, cruise at altitude, descend, loiter, further descent, and land. This accumulated distance, if including a substantial distance component for manoeuvring and loitering, may be significantly greater than the nominal trip distance from point a to point b (a. k. a. , block range rb , as will be discussed later). Cruising at altitude is a major component of a mission profile, and performance assessment for this state is a good indicator of a given aircraft"s range and endurance capability. We will focus on cruise at this juncture of the course. Given this correlation, here we will separate the aircraft"s range and endurance performance assessment into two categories: jet aircraft, and propellered aircraft. One can define a pertinent performance parameter, thrust specific fuel consumption (tsfc), as follows: Tsfc = kg/hr of fuel / n of thrust delivered, kg/hr@n.
