What is cruising altitude for an airplane?
According to USA Today, the common cruising altitude for most commercial airplanes is between 33,000 and 42,000 feet, or between about six and nearly eight miles above sea level. Typically, aircraft fly around 35,000 or 36,000 feet in the air.
What altitude should be entered for your cruising level of an IFR flight plan?
600′ ceiling, 2 miles visibility, if precision approach. If no approach exists for the alternate runway, descent from cruising altitude must be possible under Visual Flight Rules.
What is cruising altitude for 737?
41,000 feet
The Next-Generation 737 airplanes are capable of cruising to a maximum altitude of 41,000 feet, compared to 39,000 feet for the competition. In addition, advanced-technology Blended Winglets are offered as a production option on the 737-800.
What altitude Should you fly when operating in cruising flight at more than 3000 feet AGL?
According to FAR 91.159, if you’re more than 3,000 AGL, you need to be flying an odd-thousand MSL altitude +500 feet on a magnetic course of 0-179. And if you’re flying a magnetic course of 180-359, you should fly an even-thousand altitude +500 feet.
Max available thrust is related to the altitude and the speed of the aircraft. These are just two examples. Other engine designs will vary, but this gives you an idea of the overall difference between thrust available on the ground and in the air. In the past, at least, Jane’s gave cruise thrusts and SFC’s for many engines, usually at FL350.
What is the cabin pressure at cruising altitude?
At the normal stratospheric cruising altitudes of 30,000–38,000 ft, the outside pressure is 0.3–0.2 atm, respectively, while the cabin pressure is maintained at a level equal to that found at altitudes between about 5500 ft and 8000 ft, or between about 0.8 and 0.7 atm.
What’s the thrust of a Lear 40 at altitude?
Dynamite, keep in mind the 3500 lb rating for the 731-20 engine on the Lear 40, at SL ISA conditions, is for an N1 of 85% or so. Maximum cruise N1 is normally 100% N1. So to compare thrust at altitude with SL thrust involves more than just pressure and mach differences, but N1 also.
How does TSFC and thrust change with altitude?
Thrust and TSFC are quite ugly functions of both. For a JT9D I would set the TSFC at common cruise altitudes and speeds to about 0.65 to .7 Thrust decays with altitude, linearly with density. On the other hand it changes with Mach number, strongly depending on the bypass ratio (high bypass > decay; no bypass > increase).
