@nickleeson00 They got a clearance from their position direct to DUNKN intersection.
It must be an intersection somehow close to the flightplan route, or in the route but you have to cross a number of intersections to reach it which can make your flight shortened in time and distance
REF: Direct to Destination In most countries we are on assigned routes. However North American ATC does allow direct more often but it is limited direct to the point at which you will begin your descent to join the arrival corridors (aka-STAR "Standard Terminal Arrival Route") We definitely prefer the shortest route whenever possible.
If an aircraft slows down to stall speed it means it will fall like a rock from the skies, right? So, when landing a plane the pilot must make sure it hits the ground with velocity above 162 knots. Is that right?
It will not fall like a rock out of the sky no. A stall basically means that the wing is no longer producing enough lift to continue stable flight in which you see here in this video. Since the air is so thin up there if you begin to slow down you will never be able to regain that airspeed unless you descend to a lower altitude where the air is thicker, but airplanes when in a stall are still producing lift so it is still flying just not as well. As far as the landing speed it depends.
The weights and air temp. along with air density, and so many other factors is what determs the airspeed needed for landing, this aircraft although it is big the wing along with slats and flaps make it very big thus making the air having to travel over it speed up creating a lot of lift even though the airspeed is slower, most of the time Vref for the Global 5000 is around 108 knots
One thing though: since you're flying above the tropopause, isn't the temp suposed to max around -56,5ºC before increasing slightly?? I noticed the outside temp was -67ºC.....which is VERY COLD!!
I bet that you guys don't wear that mask all the time when you're up there, that was just for show. If you do you have to recharge your bottles every other flight. We fly at those levels and we are aware of the FAR but we dont put the masks.
Really there is not much weather up there, we are above most of it so turbulence is not a big concern although it can be up there and if it is than we wont fly that high since the over speed and stall window is so narrow
Well the higher up you go the air gets thinner, so with that being said there is less drag if you will and also up there the engines are in there butter zone. At those altitudes the wings are not doing as much work as the engines are to keep the aircraft flying so you because the air is thinner and there is less drag you are not burning as much fuel as you would be at lower altitudes. As far as speed goes you are not going any slower and this goes back to the air density
@upintheskyx80 if i'm correct, you're saying that regardless of air density, the engines will provide the same thrust at any altitude? but are more efficient with fuel burn at high altitude?
with decreased density that decreases overall lift over the wing, but also decreases overall drag over the wing too. is it fair to say that as u increase in altitude, efficiency of the wing increases because drag decreases more than the lift decreases? or is that true?
@wilatemodel Yes there is a difference, but I don't know why. The higher the latitude the slower sound travels. therefore near sea level sound travels at around 720mph, where as at high altitude it is something like 680mph.
The maximum speeds on Globals works like this. From 8,000 feet and higher you can go 340 KIAS (knots indicated airspeed)or MACH 0.89. Beginning at 8,000 feet 340 KIAS is approximately MACH 0.59. At 30,000 340 KIAS works out to MACH 0.89. The MACH limit speed then becomes the limit and that number stays constant up to 35,000 where it starts to reduce to MACH 0.842 at 51,000 (typically shows 210 KIAS). The true airspeed is derived from a number of factors including temperature.
@wilatemodel That speed is indicated airspeed, not speed over the ground. Since the air is less dense that high up, less air passes over the aircraft at higher speeds. This is why the indicated airspeed could be only 190kts, while the speed over the ground could be 500-600 kts.
@upintheskyx80 I always thought also, well you forsure save fuel but go slower. Maybe in that specific aircraft, higher you go, the faster Im not really sure. I suppose you can only judge that by what the winds are.
thanks for the share! awesome video!!! those quick donning masks look funny :) who do you fly for?? Flying corporates is my long term goal, if you have any advice would be highly appreciated thanks again sir
@bb1134 And, someone should take President Obama up to FL 510 to show him that corporate jets ( and Las Vegas and capitalism, in general ) are a very cool thing and should not be demonized.
@85iceman The sad part is when Obama is out of office in less than 2 years he will travel the country in a corporate jet giving speeches. What a hypocrite that man is.
Above flight levels 410 it is required for one pilot to have an oxygen mask on in case of a decompression. There would only be a few seconds to don the mask before you would lose consciousness and at FL510 you barely have a second or two.
Thankyou very much. I never understood why you loose your con. so quickly. On airliners I was told that the air is actually pulled out of you as well.
Should a decomp occur at that altitude. Would the copilot be able to "save" the passengers and the other pilot? I know this is highly unlikely and surely would be a terrible experience but I would hope that everyone else is able to get breathing quick because it sure would emotionally take a complete toll on a pilot if they had to land an aircraft full of dead passengers.
The aircraft certification process takes into consideration the time for the aircraft to descend under Emergency conditions to15,000 msl which is considered to be a safe altitude for most people to breath. The certification takes into consideration TSU (Time of Safe Unconsciousness) which is applied to passengers who hypothetically are not able to don an emergency mask. The idea is keep a pilot conscious so they can get the pax to a safe altitude in minimum time. Autodescent is also an option
@upintheskyx80 i thought the 5000 had quick donning masks? you squeeze the two read tabs together to pull it out, then on your head u release them to have it clamp down, no?
Most flights we cruise between 47000 and 49000 because for us this is not a problem. When we fly across the Atlantic or Pacific we will normally start out at 43000 and work our way up to 49000. This is because we are heavier due to the amount of fuel we have to carry in order to do these flights. On this particular flight we flew between Canada and Florida
Actually it was FL510 51,000! Yes it is more efficient at those altitudes but it is all a matter if you can get up there too. A lot of considerations have to be made such as weight, temp., pressures and so forth.
yeaah... well i think that it's more useful to maintain fl390 or 400 during some flights but as you were crossing the atlantic and with a buseness jet right? ... so you can reach the ceiling by climbing at differents steps of the flight...well done man!! well hope see more of your landings with this aircraft!! seeya
