How do I decide my altitude?
Answer: The flight operator files a requested altitude, usually done by the flight dispatcher, based on performance and economics. Air traffic control reviews the flight plan, checking for conflicts. They issue the cruising altitude based on the requested flight plan and other traffic.
How does VS speed vary with altitude?
On average, true airspeed increases about 2% per 1,000′ of increase in altitude, but the actual change depends on temperature and pressure.
How do you determine flight planning altitude?
The quickest and easiest way to find out how to stay out of the rocks is to look at the maximum elevation figures (MEF) along the route of flight. MEFs can be found inside the latitude/longitude quadrangles on aeronautical charts, with the larger figure indicating thousands of feet and the smaller hundreds of feet.
Which is the speed which gives the maximum range?
The speed which gives the maximum range for a given aircraft weight and altitude is called best range speed. Flying at higher speeds than the best range speed increases the drag and the fuel flow, and therefore reduces the range.
How to calculate the range of an airplane?
Assuming a constant ground speed, we can use a simple rate equation to determine how far a cruising aircraft flies in a given span of time. The general rate equation is “rate times time equals amount”. The amount is the distance d the airplane has flown, the rate is the aircraft’s ground speed V, and the time is the time t aloft.
How does flying at higher speeds affect range?
Flying at higher speeds than the best range speed increases the drag and the fuel flow, and therefore reduces the range. Lower speeds than the best range speed reduce the drag and the fuel flow, but they also reduce the distance traveled per time which is more dominant, and therefore reduce the range.
What’s the best glide speed for maximum range?
Look under emergency procedures for engine failure. Find the recommended glide speed for maximum range. This glide speed is the speed for L/Dmax(I’ll save you the derivation). This speed also corresponds to the bottom of the drag polar.
