fuel consumption for a Boeing 747 commercial jet in cruising position has an approximately normal distribution with a mean of 3212 gallons of jet fuel per hour at a standard deviation of 175 gallons of jet fuel per hour

a) fuel consumption of a boeing in cruising position is in the lower 20% of the distribution the plane is used for economy trips find the maximum fuel consumption in gallons per hour required for a Boeing 747 in cruising position to be use for economy trips

b) when a Boeing 747 is in cruising position what is the probability that the fuel consumption is more than 3100 gallons per hour?

c) for any Boeing and cruising position what is the probability that it's fuel consumption is between 3000 and 3500 gallons per hour?

d) an airline company has a fleet of 20 Boeing 747 planes find the probability that the mean fuel consumption of the fleet in cruising position will be at most 3300 gallons per hour?

answers:

a) x = 3065

b) 0.7389

c) 0.8374

A Boeing 747 "Jumbo Jet" has a length of 64.4 m. The runway on which the plane lands intersects another runway. The width of the intersection is 23.6 m. The plane decelerates through the intersection at a rate of 5.50 m/s2 and clears it with a final speed of 46.9 m/s. How much time is needed for the plane to clear the intersection?

Industrial Electronics 4) According to the Boeing Commercial Aircraft Company, a Boeing 747-400 aircraft has a maximum gross take-off weight of nearly 400,000 kg. Four pressure sensors are used to verify the weight reading found from suspension systems of Boeing aircraft. Each pressure sensor output is calibrated to produce 10?? for 1 Kg of weight. Design a circuit using op amp, which add the four voltage levels from the four pressure sensors and check whether the sum exceeds the maximum...

The fuel efficiency of an aircraft’s jet engines is described by the thrust-specific fuel consumption (TSFC).

The fuel efficiency of an aircraft’s jet engines is described by the thrust-specific fuel consumption (TSFC). The TSFC measures the rate of fuel consumption (mass of fuel burned per unit time) relative to the thrust (force) that the engine produces. In that manner, even if an engine consumes more fuel per unit time than a second engine, it is not necessarily more inefficient if it also produces more thrust to power the plane. The TSFC for an early hydrogenfueled jet...
