G'day folks So at school today I had some spare time at the end of lunch hour so I figured I'd go for a walk around the hangar and see if there's anything new and exciting around. So as I get over the far side there I was having a look at the Falcon 20. Nice looking airplane, but definately has some interesting features (a key lock on the main door, aft fan turbofans, etc). One of those ...

It has been bothering me since I first noticed it on a 777. There's a small slat or a flap on the leading edge of the wing next to the 767/777 engine pylon. I suspect that it's a small Kreger flap just like the ones on the 747, but I'm not sure. I also noticed them on the 300/310s as well. Because it's so small, it makes you think why it's even there. Does it make significant "lift" if ...

Hi everyone! I have come on many ocasions across this, without ever understanding what do you talk about when you refer to either "normal law" or "direct law". I have done some research but, alas, no useful results so far. Would you mind explaining what do you mean when you refer to it? I hope it is not something as simple as to make me blush with shame for not being able to ...

I was wondering (while browsing the DB ) when do vortexes build? Do I have to wait for some special weather or so if I was willing to catch one of those...? This was the pic which made me wonder: View Large View Medium Photo © Paul Markman I would love to read your thoughts. Take care, and good pictures... Lars

Hi everyone! I am asking this because it is something I have always taken for granted, that is, that both pilots would have to wear them, particularly during the critical parts of a flight. However on the next image the captain does not wear it, albeit they are close to landing. View Large View Medium Photo © Ismael Jorda What are the rules about this? In ...

I was just wondering, what is the whell rim size of most wide body? I believe a 747 400er and 777 rims are 50".

Not intended to be flamebait - serious question. I was on a U2 A319 back in April at AGP . We were sat at the gate waiting for WX at LGW to clear - it was snowing a lot back home and we ended up moving to a remote stand to wait. The crew were great and did their best to keep everyone entertained - we were there for about three and a half hours in the end. Anyway, the flightcrew ...

Hello, I guess braking performance has critical importence when aborting a take off. I've examined various tables, performance charts for take offs (mainly open to public) and I've never seen such a variable. Except DRY or WET runways. So, is there an assumed value of braking coefficient for dry and wet conditions? I think poor braking performance of runways are announced as NOTAMs or ...

The other day, I was listening to LTBA ( IST ) delivery frequency and I witnessed a pilot-ATC dialogue I have difficulty to understand. I am still trying to figure out, I guess I need a big help here. Quick information, the usual routine at IST it to assign departing traffics the runway heading to fly, then giving direct routing to a fix if not, radar vectors. The departures are ...

So, I was wondering. When ATC say this to an aircraft when giving takeoff clearance, what exactly is the aircraft receiving this warning supposed to do with the information? Ok, I suppose it means they won't be surprised if they hit some harsh bumps, but other than that, what can they actually do to minimise the hazards? It kind of strikes me as similar to those signs you see when ...

Around the globe is there one country,more than any other, that you really feel most comfortable in flying through their air space?

I saw a chart in a photo in a magazine.....Anyway it was clear enough so I could read it, and it appeared as though there was a latitude limit for the 747 and 757 over greenland. It was a sectional chart of some sort, and I have never seen one of these, so I have no idea. However, it caught my attention, so I'm wondering if someone can enlighten me. Thanks, Nick

What's a good type rating to have for corporate/charter flying?

I found an interesting page describing ten aviation disasters that stimulated the greatest advances and changes in aircraft safety to what it is today. http://www.popularmechanics.com/science/air_space/ 4221138.html However, I was surprised to see the absence of one aviation disaster in particular: American Airlines flight 191 (DC-10-10), Chicago O'Hare, 1979. http://en....

Hey ramp, engineering and pilots (and any other loud environment people.) What is everyone using for hearing protection? My dB Blockers just came in the mail today so now I will be wearing them on the ramp. The Mickey Mouse ones wont fit under my tuque or my hood, and I kept on finding my self out there with only one foam plug or two soggy ones. Is anyone else using custom fitted plugs? ...

With the A380 showing the world, that you can slow down a big four engine jet with only two thrust reversers, I wonder will Boeing follow suit, or will stick with four like the rest of the 747 family. So do any body here have any ideal? I personly hope they stick to four, because that the number the 747 always had. I am happly that is redesigning the Queen Of The Skys with larger window ...
