Final answer:
The specific fuel flow rate at 11,000ft and 65% power cannot be determined without the aircraft's performance data. Generally, fuel flow decreases with an increase in altitude for piston-engine aircraft. Comparisons of fuel efficiency between cars and airplanes highlight the importance of vehicle occupancy and energy expenditure.
Step-by-step explanation:
The question posted is related to aeronautics and aviation, specifically regarding the fuel flow of an airplane at 11,000ft with 65% maximum continuous power. However, answering this exact question requires specific data from the aircraft's performance charts or operating manual, which are not provided here.
In general terms, the fuel flow at a given altitude and power setting can be calculated using performance charts specific to the aircraft in question. For example, piston engines typically consume more fuel at lower altitudes and less fuel at higher altitudes due to changes in air density and engine efficiency. However, without the specific make and model of the aircraft and its associated performance data, calculating the fuel flow is not possible.
Instead, to illustrate similar principles, let's consider the information related to energy efficiency in transportation. For instance, when considering fuel efficiency in cars versus airplanes, an airplane may achieve 90 miles per gallon (m.p.g.) per seat when fully occupied, which is comparable to a doubly-occupied car that gets 45 m.p.g. On the other hand, if we consider a car achieving 24 m.p.g. matching the energy expenditure of an 80% full airplane, it shows that per-passenger basis fuel economy can be comparable in some cases between different modes of transport.
