| landing speeds | |
John Worthington  15th May 2011 15:40:38 | I'm looking for info on plane landing speeds, especially the `Heavies` please |
| Pete Gummerson 15th May 2011 15:46:20 | Look up in the FSX learning centre in FSX it will tell you a bit about each plane in that, also if you bring up the pilot note-pad while in the game (Shift + F10) it will have a bit in that under referance. |
Steff Missot   15th May 2011 16:47:26 | I think you mean Approach speed.
You need to have a several numbers: - Aircraft Weight on approach - Flap settings - Aircraft type Should be more factors but this are the most basic I think. There also should be a formule for it(don't know it:P) In the planes with a FMS, it calculates it for you |
Isak Kindgren  15th May 2011 17:40:24 | Don't know if this is correct but I think the formula is something like multiplying the stall speed with landing configuration (gear down and flaps full) with 1.3. Again I don't know if this is correct! So the things you need is the stall speeds.. |
| John Worthington 15th May 2011 18:43:09 | Yes your absolutly correct, I did mean stall speed because I have damaged a few undercarrages with the `heavy` planes, not often but I can't understand why exactly. I get eveything right in flaps, gear, etc, but then I get the message, You landed above the angle speed and crashed the aircraft. I'm on ILS as the localizer takes over at 15 miles out which shows I'm on a good glide slope and just feet before I touch down I cut engine speed that is usually around 175 Knts and I also switch off the AP at the same time as I flare for the landing. I'm ok some times with this action, but can't understand fully what is wrong when the plane lands heavily. Hence I need to know the stall speed. I've been looking through the `FSX Learning centre` but without sucess so far :O( |
Graeme Brown  15th May 2011 18:52:38 | In modern 'glass' cockpits the stall speed is usually indicated in some way on the airspeed indicator strip (in red I think). You mention about being 'above the angle' when you crash. Is it possible that you are coming in too slowly and/or over-flaring and striking the tail? |
Joe Clifford  15th May 2011 20:31:55 | This forumla is pretty complex so listen carefully :)
1) Double the weight of the aircraft, including passengers ect. 2) Get hold of the air pressure of where you want to know the stall speed. (example: QNH on the approach to Birmingham). Then find the Maximum value of lift for wings. Then find the Area of the wing. Times all of these numbers together. 3) then divide the aircraft weight by the number above. And square root it. Providing my memory is correct that should give you your stall speed. Joe :D |
| John Worthington 15th May 2011 20:43:42 | Graeme, in answer to your question `Too slow` I think that's the problem but I'm not flaring the tail strike, it's the wheels that hit hard as if I'm at the correct angle but the plane falls heavy, but dosen't crash, but I'm given the message that I have crashed ? This is in VA mode only. So my name is mud with the Boss who has to pay for the repairs :O(.
Joe: Maths isn't my good side mate, I have enough problems counting my Lottery wins :O) |
| Joe Clifford 15th May 2011 20:58:09 | Have a look at this site : http://freechecklists.net/simchecklists.asp
They large aircraft have the speeds to fly at different stages of your flight. See if that helps. Joe :) |
| John Worthington 16th May 2011 16:54:47 | Thanks guys, I seem to have found what I'm looking for by trial and error. I have found that the `heavy planes` can go no lower speed on landing than 175 knts, maybe 172 is the lowest but I have found that if I come in at 180 then about a mile out I can reduce the speed to 175 then flare slightly about 5 ft from touchdown, I not only land gracefully but I save rubber too. The Boss will be over the moon now :O)
Take care, regards to all. John |
Gordon Thorpe  17th May 2011 23:31:39 | JOHN THE BOSS IS OVER THE MOON AT THE HRS YOU PUT IN EACH MONTH & BUY THE WAY YOUR LANDING RECORD IS A LOT BETTER THAN MINE SO I WOULD NOT WORRY TO MUCH GORDON

| John Worthington 20th May 2011 08:23:55 | Any chance of a pay rise` BOSS` :O) |
Monty Howard 23rd May 2011 07:26:37 | I love to BING - GOOGLE for things like plane model and POH IE: Cessna 172 POH.
POH, is the Pilots Operating Manual and it clearly explains everything about the plane for which it was written. This is the user manual which comes with a new airplane from the manufacturer. You will find speeds, check list, and numerous other things about the real aircraft. Most of the manuals are sold at a rather high cost but many common POH manuals are available free on-line if you look. |
| Monty Howard 23rd May 2011 07:35:48 | Correction, I should have typed;
POH = Pilots Operating Handbook |
| John Worthington 24th May 2011 07:30:54 | Thanks Monty, that's a very useful area to explore.
I just read through the Cessna pages and was shocked to find out how many accidents are happening very frequently because of `new` pilot arror by not having the correct training in ILS etc. |
