  1. There is no such thing as a silly question. There are however really stupid answers. If someone wants to know something, and they genuinely dont know the answer, then tell them. Just because you think it is a very simple thing, doesnt mean others do.

    Yeah, right... especially when both your instructors are members of this forum and you're still before the flight test...

     

    And now I'll just 073_bye.gif.391d1ddfcbfb3d5f69a5d3854c2b0a02.gif and hide for a while...

  2. Other human factors not in the list could include:

    Most of those can be classified as part of the already listed groups:

     

    * information overload

    * pilot personality (e.g. reckless, uptight, impulsive, over-confident)

     

    * hypoxia

     

    * blind spot problems - perception

     

    * the bends (caused by diving within a few hours after flying) - pre-flight preparation / judgement

     

    * disorientation - perception

     

    * flicker vertigo

     

    * health problems since the last medical (e.g. diabetes, heart disease, stroke) - pre-flight preparation / judgement

     

    * alcohol or drugs (legal or illegal) - pre-flight preparation / judgement

     

    * CO poisoning - I'd say, that's more of a mechanical fault than human factor

     

    * visual illusions (e.g. runway perspective issues) - perception

     

    * etc (they're the ones I can think of just now)

  3. I'm confused too. What is the "Jabiru Rotax 912 family" ? I always thought they weren't even related. Where did the 356 mechanical failures & 284 forced landings come from & what do they refer to? Sorry but this does sound like crap.

    Looks like the forum didn't like the formatting, It's supposed to be 35 mechanical failures and 28 forced landings for Jabiru, and 6 and 4 respectively for Rotax 912 family.

     

     

  4. From Wikipedia:

     

    On 12 April 2007, New South Wales, Victoria, Tasmania, and the A.C.T. agreed to common beginning and ending dates for DST. Beginning in 2008, the start of DST in these states and in South Australia occurs on the first Sunday in October, and its end is on the first Sunday in April.

    I'm not sure if this can be put in any simpler way.

     

     

  5. NewI've been doing Trigonometry all day and my head's spinning, but that sounds like one of those grandma recipe things which requires calibrated eyeballs.

     

    Guess that I didn't explain myself.

     

    You are on final and lined up with the centre line

     

    You are crabbing 10 deg determined by the compass

     

    determine the X wind by the 10 deg factor.

     

    It was in a forum or book about a couple of years ago but don't remember the answer.

     

    Could have been 1 deg = 2 knots or 1 deg = 1 knot.

     

    Assuming you have a compss that is.

     

    Phil

    Just ran a quick calc on this one and what you're looking for is:

     

    x/w comp = sin (angle in degrees) x IAS

     

    Since for low angles (blow 10 deg) sin function is almost linear, you can replace the sin (angle) with 0.017 x angle.

     

    So for a approach speed of 50 kt and angle of 10 deg you'd end up with something like: 0.017 x 10 x 50 = 8.7 kt cross wind component or rather 0.87 kt per one degree.

     

    At 60 kt it's about 1 kt per degree.

     

    At 75 kt it's about 1.3 kt per degree.

     

    But as TP mentioned this only works in constant wind and at low angles.

  6. Just got home from work.Flew out of Roma this morning. The security x ray machine is all set up and is being used.(Security Peeps where under training).I even had a explosive test done on me.Simple test, a wand is place on your clothing, then it goes in a machine. All Clear:smile:Dunno-what will happen when one the peeps from a mine, that packs explosives into the drill holes will register when the wand is put into the machine. bomb.gif.8dfedc171d37efc22ba0dd32e933ffc0.gif

    I've heard a report from a military sapper, or at least someone who was blowing stuff up for the army, that got tested positive for the explosives.

    He just explained who he was and what he did, and all he had to do is to pack all his baggage into plastic bags so that he wouldn't contaminate other people's baggage.

     

     

  7. I guess the main thing with security for planes is that once the plane takes off there is no way to get on or off from it until it lands.

     

    That means that if there would be any hostage situation to happen, there can be no police / special forces intervention until the plane runs out of fuel.

     

    That being said I think most of the airport security is getting over the top. Most of it was implemented to make the governments look like their doing something in the war against terror (not that you can define that as a war anyway) to keep the public focus out of internal issues for a while.

     

    One think I'm grateful for is that the worlds is still a bit behind the US where you can be groped, but can't grope them back: http://www.huffingtonpost.com/2012/06/19/carol-price-woman-accused-of-groping-tsa-agent_n_1609223.html ;)

     

     

  8. Hello,

     

    I'm looking at buying a trike and I have a bit of a dilemma as to what radio and headsets to get for it?

     

    Is it worth going with the Microair and Lynx from Airborne?

     

    From looking at the Vertex 220 radio for example it seems to have really small buttons, which may be a bit hard to operate in the trike.

     

    I've seen the headset discussions in other parts of this forum, but they mostly relate to GA headsets.

     

    So I'd appreciate any advice about the headsets and radios that you use.

     

     

  9. Now that I've started learning to fly I get really amazed by the way birds manage to fly and how unfit for flying we are as humans.

     

    When you look how much input the bird can have to it's wing shape, angle and lift generated by it and how much feedback it's getting throughout it's body makes me wonder sometimes how we can stay up there with the limitations we get.

     

    If you look at that osprey it goes from a gliding configuration, that many glider pilots would envy, to shape suited more for jets, and then to almost a VTOL from water with a load that's trying to get away and all that on "bio-fuel".

     

    I'd buy a plane that could do that any day 045_beg.gif.b05ea876053438dae8f282faacd973d1.gif

     

     

  10. Historically, English originated from the fusion of closely related dialects, now collectively termed Old English, which were brought to the eastern coast of Great Britain by Germanic (Anglo-Saxon) settlers by the 5th century – with the word English being derived from the name of the Angles, and ultimately from their ancestral region of Angeln (in what is now Schleswig-Holstein).[12] A significant number of English words are constructed based on roots from Latin, because Latin in some form was the lingua franca of the Christian Church and of European intellectual life.[13] The language was further influenced by the Old Norse language due to Viking invasions in the 8th and 9th centuries.

    The Norman conquest of England in the 11th century gave rise to heavy borrowings from Norman-French, and vocabulary and spelling conventions began to give the appearance of a close relationship with Romance languages[14][15] to what had then become Middle English. The Great Vowel Shift that began in the south of England in the 15th century is one of the historical events that mark the emergence of Modern English from Middle English.

    http://en.wikipedia.org/wiki/English_language

     

    So it's Germanic with Latin, Norse and French influences.

     

    P.S.

     

    Being a non-native English speaker I also think that English spelling makes no sense whatsoever.

     

     

  11. MarkJust bear in mind the following:-

     

    1) Glide ratios on an Edge X are going to be significantly worse than JG's Sav. Hence your "out of luck" time will be longer in terms of NM's and because of the Trikes slower cruise therefore much > in terms of time. Throw in some headwind component (always much> as a percentage of cruise on a trike) or worse a side wind, where your impacted whether you push on, or turn back, and what might have been fun might really rapidly become a whole lot less fun

     

    2) To get a best outcome for the glide ratios appropriate for a trike you obviously need to be high......I'd be wanting a heated flight suit, and a means of making sure I could continue to see out the helmet visor. End of April can have some transitioning to winter weather.....

     

    3) wing loading on a trike is light, An uncomftable set of bumps in a 3 axis is likely to be "wishing I was down there" in an Edge X with a wizzard wing.But then I may be a coward and certainly wouldnt want to play this particular game with a wizzy, in fact Im not sure i have the neccesary balls to even play it when armed with a streak...

     

    Andy

    Also the Edge x with it's 44l fuel tank won't leave you a lot of wiggle room for an almost 100nm journey.

     

     

  12. I do believe though that they are definitely over charging you if they charge the same amount for training in your trike as they do for theirs. I always tell people that they should do all the training in the instructors machine until just before solo. A fair price would be normal cost minus fuel and estimted depreciation and wear and tear.Bluey.

    I think it would be more a matter of discouraging you from trying to learn on your own aircraft, as it would be more hassle for the instructor.

     

    After all the instructor should know his own trike, how it was maintained, etc, whereas with a students aircraft you have the added worry if the aircraft is ok.

     

    I guess the less outside factor the instructor has to worry about the better for the student.

     

    Also I wouldn't change the plane just before solo - solo is enough of new things to process even in the same trike.

     

    F_T - stop trolling, it's not working.

     

     

  13. First thing I'd change is the text on all the drawing in Rules of the air and Ground marshaling directions (sections 4.04 and 4.05)

     

    I appreciate that someone draw all those pictures by hand, but it's really hard to make out whet the text on all those pictures says.

     

    Pictures can stay but the text should be redone.

     

     

  14. So back to my EXAMPLE of when/how to cross the road: With or againist the lights.

    The law aside, there is no guarantee that either is safer.

     

    The person crossing the road has the final say in what they do.

    I have to disagree with this statement.

    There is a guarantee that crossing the road 0n green light is safer, as you can expect most of the traffic to give way to you.

     

    There is no guarantee that doing it either way is perfectly safe.

     

    It's the same difference as with accepting that there are some risks in life (or flying to be more on topic) and actively looking for risky situations.

     

    Why are people seemingly obsessed with pointing out the failings of people who made the "WRONG" decission and the end result is death?

    Granted it is/was not advisable to go flying at/just before sunset. Sure it was not advisable to not have weather. etc, etc.

     

    However, the PIC made a choice. The important thing for US - who are still alive - is to LEARN from what happened rather than JUDGE the decission.

    The main reason for this is that a decision of one man may or will impact us all. Since CASA and RAAus are both organizations with a primary goal of making flying safe for everyone if they notice a trend of people making a choice that is not safe they will have to regulate it more and put in more restrictions and supervision, one of which could be a requirement for lodging a flight plan for every flight with them and them having the ability to forbid you to make such flight in case your arrival is after sun set (similar to traveling through controlled air space in a RA plane).

     

    Can you see how this would lead to a death of recreation flying for everyone?

     

     

  15. From a very comprehensive look at what is being offered around at the moment, quite a few if not all second hand trikes being offered for sale at the moment are under valued. In many cases sellers seem willing to accept a 10 to 15 thousand dollar loss to move the trikes to new owners. This attitude is making it very difficult if not impossible for sellers who wish to get a fair price for their trikes. It is now the case that second hand 912's do not hold value at all well. This was not the case a few years ago and airborne agree.Bluey.

    Bluey,

     

    it all depends from which side of the fence you're looking at this problem.

     

    I'm currently on the opposite side, where I'm looking for a trike to buy. I'm even considering a XT-912, and to me it looks like there are far less trikes for sale than you make it to be.

     

    All I can see are either trikes with reasonable (say under 200) hours that are listed for pretty much the price of a new one ($55 -60k) or ones like yours with 600 hours around $40k.

     

    Considering how essential and critical proper maintenance is on any aircraft I find it hard to justify buying one that I have no idea how it was maintained (the log books can help, but there's a lot of planes with just a sketchy log books) just to safe a couple grand.

     

    It's also a hard choice between a 912 with 400-600 hours, which most likely is a ex school plane with tons of take-offs and landings (a lot of which would be less than perfect, considering a how some of my landings look like - I'm still learning) and again uncertain maintenance record over a new 582.

     

    So to finish my rant - I wouldn't say those trikes are undervalued by that much, especially when you compare them to a used car, when you lose 10-20% the moment you leave the dealer.

     

     

  16. One other thing when considering buying vs hiring is something one of my friends used to bring up a lot when talking about his boat.

     

    If you have your own, and especially if it's hangared at the airfield you have way more motivation to just go flying.

     

    Whereas if you need to hire it, you not only have get the right weather, have free time, but you also need to make sure that the plane will be available and that's just another step that brings you to the too hard territory.

     

    If you have an aircraft ready to go you can always pop in before or after work, or whenever you have some time, without any prior arrangements and fly for as long or as short as you need.

     

    If you need to hire one, you need to know in advance, arrange the hire, specify how long you're going to fly, etc and then you just give up...
