What is the ideal approach and final approach KIAS for the 747, it seems like I always come in too slow.......
Thank you all.
Hello Ohiosimmer! Here's the answer:
When you intercept the localizer, you have to establish a speed of 220 KIAS.
When you lower your flaps to 5-10 degrees, reduce your speed to 200 KIAS. When you get to 200 KIAS, lower your flaps to 20 degrees and reduce your speed to 180 KIAS. When you get to 180 KIAS, put your landing gear down, and after that set the flaps to 25 degress or full. You will come perfectly.
Now, when you are on final glideslope descent, reduce your speed to 170 KIAS. Finally, landing speed is 160 KIAS.
I hope this help you.
I think those are good ballpark figures but remember you must take into account aircraft weight and flap setting. B752 for example at 62 tons Vref flap 30 is 107KIAS for 110 Vref 30 is 149KIAS.
Ok, back to the 747. Supplementing Agus0404's info (sometimes I wonder why i worry, Agus0404 always seems to catch these when i'm gone...i should take a vacation!)
Landing Approach Speed
Mind you, this is Vref, Landing Gear Down
880,000lb, flaps 25 - 188KIAS
880,000lb, flaps 30 - 181KIAS
450,000lb, Flaps 25 - 134KIAS
450,000lb, flaps 30 - 129KIAS
Pretty much, Follow Agus's advice untill you turn final, or are on glideslope descent.
Thanks FEM, PH, and Augus
Well, you're very welcome!
Good Luck with 'er!
Hmm, FEM won this time. He was faster than me to answer the post.
Anyway, you're welcome Ohiosimmer. We will always help you with your problems, like if we were psychologists.
Odd...it shows Agus answered way before I did in the post...flyaway's possesed???!!!
Really? That's odd, yes. Haha, so, it seems that I won again
We may have to kungfu fight!
If you wish....come over here, if you dare... I'm gonna punch you really hard, so be prepared
Alright, alright! Break it up! Nothing to see here, move along!
Hey guys, how do you know all these things? Is there a tutorial that tells you these numbers, or are these just from experience? Do you keep all this stuff on a notepad for later reference or do you just have it memorized?
We are smart guys
I know all this information because I am an aviation lover and I have a folder where I keep all my information about aircraft, navigation, ATC, checklists, etc, etc, etc. Now, I like to fly using my checklists. Every pilot does that. And I'm kind of used to it, so I know all those numbers.
I get all the information from the Learning Center. I print what I want and then I put it on my folder.
Never admit having the Folder Agus Keep the info but never admit the folder!
(I have one too with printed logo's of all th major Ailines on the front!).
I like my folder, hehe. Lots of information.
You have a cool front. Mine is all blue, a dark blue. It's pretty cool, but I'd like to put some logos or a cockpit on the front.
All my Info came either from Delta VA's PDF files, or the Learning Center
