"Subside" (forward openening) doors are (almost) a car feature of the distant past, for very similar reasons.😈 i was talking about the 172. the hinge is at the front so you are pushing against the airflow. i am not talking about 1930 suicide doors.
skippydiesel Posted June 20 Posted June 20 Jesus! Whats happening with this web site ? - just lost a second posting.😈

You can't have it every way. Either the doors, should they open in flight, stay closed due to slip stream/air pressure or they don't. As stated , your gullwings are "suicide like" in this context . As suggested, your doors are a design failure. It may be that a redesign is somehow not feasible - This does not change the fact, just demonstrates that a rsky compromise has been accomodated. I rest my case😈 Edited June 20 by skippydiesel

facthunter Posted June 21 Posted June 21 IF you ask that question you would not understand. Some Aeroplanes easily fly with a door Open. Nev 1
Kiwi Posted June 21 Posted June 21 If you want to open the doors on a Rans S6S, you slow down to 50 knots, open door, then speed back up. 1 2
onetrack Posted June 21 Posted June 21 Skippy, you're taking things to extremes. A gullwing door cannot be compared to a "suicide" rear-hinged, front-opening door, because rear-hinged doors get ripped open savagely in the slipstream, and can pull people out as they try to grab them. I have personal experience of this, I nearly fell out of my brothers '48 Chevrolet sedan, when I was about 9, thanks to trying to close an improperly shut rear "suicide" door at speed. Childish inexperience at its best! A gullwing door has far less potential to be ripped open if it comes unlatched at speed, because the door is presenting minimal frontal area to the slipstream. 1
skippydiesel Posted June 21 Posted June 21 (edited) BrendAns post".....but just as i turned final my door blew open so i had one hand holding that shut and the other working the throttle and stick. did one of my best landings funnily enough. nearly crapped myself when the door opened, sudden loud noise and the plane yawed left. " Seems to me you didnt read BrendAn's post - Repeated above for those who didnt read or miss read. He may have been gilding the lily a bit, to make his challenge a tad more exciting, than it actually was, however, I took him at his word. Sounds distinctly unpleasant and if accurate (??) his heart rate would likly have been significantly elevated. If such a ho hum every day occurrences, I am sure BrendAn would not have reported it. Fact is fact - Gullwing doors, do not confer the same inherent safety benefits of a front hing door. Do I need to explain further? I repeat "...suicide LIKE.." - Emphasised for the scholars of the english language, who clearly missed the "...like" Happy to elaborate further, should anyone require.😈 Edited June 21 by skippydiesel
facthunter Posted June 21 Posted June 21 You can't take Photos out of an open front hinged door and they sit a few Inches open unless you sideslip towards it. It can also distract you and freak you out a bit. A door that Hinges at the top and clips to something will stay there, slipstreaming. This is Only with a highwing configuration. A door opening over a low wing will be in a Low pressure area and hard to close... Dealing with a non secured door should be Part of your type training . if it's possible to occur. Nev 1

I rest my case😈 Getting a bit silly. We are not talking a high speed aircraft here. And the fact that the same doors are .passed by the bmaa in the UK for training , they can't be too bad. The xair I fly needs a door catch like the UK versions then the door can't open if closed properly. 2 1
facthunter Posted June 21 Posted June 21 You don't need a door that can Jamb closed either.. This is Mostly what they call common sense and situational awareness.. Nev 3
pmccarthy Posted June 21 Posted June 21 The Texan in my picture had a canopy that opened backward. It had two latches and I was super careful. My Archer sprung open a couple of times but it has an inherently safe door. My Vixxen has gull wing doors, I wouldn’t like one to pop but it s much less scary than the Texan. 2

danny_galaga Posted June 21 Posted June 21 Flight on Saturday. The usual pootle around Boonah, with passenger. Unfortunately, she started to get I'll from some exhaust fumes leaking in. I'm so used to driving bomby old cars I'm immune by now 😄. Will have to try and figure it out 7 2

But you do get immune from the queeziness that can develop from ODOURS like exhaust fumes, petrol fumes etc You only get a high level of co if it can build up. This is why people wind their windows up when they're trying to top themselves. My plane is so drafty everything just goes straight through. Naturally I must be copping a small amount, since I can smell the exhaust fumes, which must have the odourless co in it as well. And I'm aware that once breathed in, it stays for a long time, as the reason it poisons you is by latching onto (haemoglobin?) in lieu of oxygen so can build up that way. The last two passengers didn't even notice the exhaust fumes. I'm endeavouring to find where it's coming in though. I would know if it's dangerous levels of co if the piece of crap co sticker things I've bought twice weren't already out of date and permanently black. Might get an electronic detector. 2 1
facthunter Posted June 22 Posted June 22 (edited) Yes it's always been a bit of a worry as the interior is always at a pressure below ambient. The fumes can leak in at the tail or any opening.. Perhaps have more air from forward facing inlets? Nev Edited June 22 by facthunter typo 1 1
skippydiesel Posted June 22 Posted June 22 Hi Dann_G, For what its worth- Dont mess with CO. Those "....crap co sticker things" are just as you, so colourfully, describe, always have been. Get yourself a proper detector. RAA was offering & this Forum have them and if all else fails Bunnings Aerospace. This Forum is offering C02 detectors x 2 & one CO. Just in case the CO2's are actually that, don't purchase them . Personally I like the detectors that, not only alarm at above safe concentration, but also give you a Max ppm detected. I think it likly, that at certain stages, after engine start, there can be greater chance of CO entertaining the cockpit eg engine start & warm up, with aircraft facing out of wind. 😈 1

facthunter Posted June 22 Posted June 22 Most Problems with CO are in situations where it persists for a significant time period ie Exhaust leaks coupled with firewall sealed inadequately.. While you might get some crap smell on start up I would regard them as transients and not likely to be of any great consequence in the big scheme of things. You don't sit idling slowly to warm the engine or do engine checks. You'd never be sitting in a Piece of stale polluted air with a prop stirring it up. Nev 1 1
