As an ex-navigator, I missed out on celestial nav as it was retired long before I started training. It always fascinated me, but I must say, if I still had to do that in the nav course it might have gotten pretty hard. Our C-130's still carries the sextant. It isn't serviced/calibrated anymore, but ...Jump to post
Ok so got some more ideas/questions which I'd like to know why they were/are not implemented in aviation industry. 1) Why don't aircraft cockpits have a big-size "Level-Checking-Vial" like the one used in level-measurement-tools ? Those bottles with green color liquid that move based on g...Jump to post
Ok let's try one more time: Suppose you have a car with a trunk/boot. Suppose you look at the trunk and think 'hey, let's seal this sucker up, so I can have a long range tank'. So you use a lot of sealant, you add one pipe and maybe a pump. Then someone comes around and keeps asking what does the ta...Jump to post
The added weight will be the weight of the installed sealant. Do you have any pictures of the sealant? It is probably just aviation-grade petroleum resistant compound, to seal all the joints. Just think of very expensive caulking, like for a bathroom. Thick, nasty black stuff. People can't really g...Jump to post
This 12kg exemption seems to be only for Ground shipments. I don't know if there's another exemption for air though. Someone at FedEx told me about a 100g exemption, then another said that, no, freezers don't ship at all by air. I think no one really knows at FedEx. Maybe @SAAFNAV could enlighten u...Jump to post
We ship aircons and freezers/fridges all the time. Never heard of problems. Considering the pressures they are operating under normal operation, the extra bit from cabin alt is hardly likely to damage it. Talking from the top of my head, as I don't have access to the ICAO DG manual, but freezers nor...Jump to post

Cape Town only has CatII equipment. Cat 3B equipment, they only publish a Cat 2 chart. Individual airlines need to obtain their own LVO approvals for each state they fly into. When flying the Cat3B approach you would use the Cat 1 chart and the decision height (not the MDA on the chart) that the ai...Jump to post
An important airport like CPT has CAT IIIB capability, so the airlines aren't going to have a problem. Additionally, the weather there is rather good most of the year, so you aren't necessarily going to be seeing super low ceilings. There are more options that open up for GA, because they don't nec...Jump to post

As an engineer, a big part of your job would be sit and think and come up with a solution to a problem. Not ask people to do your homework.

Wonder how the pax oxygen might work? I have never seen this in the 747 much less any other ac.

There is a recent thread on a.net on cargo planes, but I can't find it with a quick look.

Uh, no, the part that produces (most of the) drag is the cross-section, not surface area, and the cross section is about 35% larger than the 777X, not to mention the wings' cross section also matters here. Also, the wider fuselage also produces more lift from below as well, especially if it's ovoid...Jump to post

Subcontracting for the UN, they have a policy the captain having a room to himself, and the rest must share.

This seems to me a North American thing, with a relatively simple written exam, and just one exam. In EASA, Australia, South Africa and other places, the fourteen-ish CPL/ATPL exams take at least 6 months of full-time study to prepare for, including proper ground school. Having just written the Sou...Jump to post
. But there's an equally valid school of thought that says if there's an aborted takeoff requiring evacuation or something to that effect, it's better to have the cabin already lit to facilitate evacuation. When everybody needs to be out of the plane within 90 seconds, wasting 5-10 of those seconds...Jump to post
If it is an Airbus aircraft, then the first step I would do is the same.
