OK.. Thanks!

hi,the PMDG site does not recognize my purchase email address and therefore i am unable to retrive my lost password and get support.any help would be appreciated..thanks yahav

Thank you all for your help!for now I will go for the Q9650 core 2quad processor and see what happens.thanks!yahav

Thank you all for your help!Although my current mother board (P5K) will not support an i7 processor I just found out it will work fine with a quad coreSo for now I will go for the Q9650 core 2quad processor and see what happens.again... thank you all very muchyahav

Hey guys,I am thinking of upgrading my Intel E6750 to an E8600And my EVGA gforce 8800GT graphics card to a gigabyte GTX480/GTX465Will this give a noticeable performance improvement with FSX and PMDG 747 ?thanksyahav

Hi,where can I find the js41 Add-On Liveries?thanks

A great addition for this beautiful PMDG masterpiece! :(yahavl

Glad it worked for you ChrisYahav

Hi Chris,Try uninstalling your original installation first Then create your MD11 aircraft(On the aircraft tab use the add button) Hope this works, if not, try downloading the beta again Yahav

TOPCAT have released the new beta version of their popular performance and dispatch program to the general public via their support forums!http://www.topcatsim.com/?page=mainThis beta supports the MD11 and will generate all performance data needed for a safe departure.Keep in mind this is still a BETA and is not perfect. Have a great weekend guysYahav

Hi Adam,Actually Bryan's charts like most aircraft performance charts are designed in a philosophy that all the charts represent the aircrafts performance at a standard atmospheric datum, this philosophy is derived from the way aircraft performance testing is standardized. This means the charts will give you the standard atmospheric performance DATAAnd the ways to correct for non standard conditions.I believe that the confusion is because Bryan has chosen to categories the charts indensity altitude in ISA conditions. This basically refers to pressure altitude as pressure altitude equals density altitude in ISA conditions Conventionally the altitude on the charts should be in PRESURE ALT.That being said, technically there is no conflict between the terms in Bryans charts(For standardization of a performance chart the density altitude with ISA conditions at a given altitude should be renamed to Pressure altitude as density altitude is just a performance term and does not represent elevation or actual altitude) Simply put the charts should be used as though they represent actual airport elevation with the options to correct for non standard atmospheric conditions.1. Aircraft altitude equals chart elevation (interpolation will be needed for accuracy)2. Aircraft performance equals chart corrected for atmospheric conditions.Hope this helped Yahav

Breathtaking! :( yahav

Hi Kan,An assumed temperature is a performance number only.Using the information from the ADC(Air Data Computer) the FADEC(basically a computerized system that controls the engines) will downgrade the engine thrust setting to simulate the performance at for example a altitude of 0ft(sea level) with a assumed temperature of 67c. So if the air is extremely cold and pressure is extremely high the FADEC will simply reduce thrust further to simulate what the engine thrust output would have been with 67c at sea level(as long as total thrust reduction is not more then 20%).In extremely favorable conditions the crew can select an alternate power setting (TO2) that would derate the takeoff thrust by 20% giving them the minimum thrust allowed.In some conditions like the one you mentioned, the lowest thrust allowed is still much more then the thrust needed(for example lightly loaded on a typical winter morning at JFK 31L)Anyway, that excess thrust is great in case some thing goes wrong and it can with the PMDG simulation :(Hope that helped.Hey Bryan did you by any chance try the high altitude charts yet?Hopefully I'll give them ago this weekend, I was thinking Quito Ecuador (SEQU) 9228ft. lets put the oxygen masks on and hope for the best :( Yahav

Hi, EricTake into account 396.800lbs is a very light takeoff weight, about 100 tons lighter then max takeoff weight.What you describe is not necessarily an over powered takeoff (Under calculated assumed temperature) .I'll explain: There is a limit to the amount of thrust the pilot is allowed to derate from the max takeoff thrust setting (let's say 25%). Under some conditions (long runway\ low takeoff weight) the available thrust even when cut by 25% is still more then enough to get us off the ground safely (that’s a good thing!) this does not mean we cannot predict the aircraft's behavior.So instead off reducing power even more which simply takes us out off the aircraft documented safe operating envelope, we predict a shorter takeoff run with slower (usually) takeoff speeds and an incredibly cool climb profile (:The unpredictable behavior you describe is probably due to Wrong trim setting and/or CG out of Aft limits or high Vspeeds (late rotation). When exceeding the required takeoff run wile still accelerating the aircraft will get airborne eventually.I would check trim setting (check FMS takeoff page) and loading. The MD11 is usually loaded with in a pretty low MAC% range (forward CG) Also, did you use Bryan's calculated general V speeds or the FMS calculated speeds? Yahav Lipinski

hi there,The more flaps you add the more drag the aircraft generates.A large flap setting will let you take off in lesser speeds with less runway and is good for clearing immediate obstacles but will downgrade climb capabilities and overall performance in case of engine failure on takeoff, so the lesser setting will usually suite better.Usually there would be a predetermined setting influenced by company policies regarding noise abatement, economics and other performance variables tailored for the specific airport (taking in to account AC weights and meteorological conditions of course).Basically the charts are there to warn of to little flaps not the other way aroundBut also to provide the pilot with operational options, In the end the pilot chooses what he feels fits the situation best. This aircraft really has the most ridicules but versatile flap/slat system, reminds a lot of the older generation up/down switch type flaps (-;Yahav lipinski

Amazing job, Thank you very much Bryan! :(Yahav Lipinski

Ok, I would leave mathematics to flight engineers (;You can just use the rule of thumb:118 feet increase in altitude for every 1C increase of temperature.10 feet increase in altitude for every tenth of inch of pressure decrease.So for example: 1 Rwy elv.2000ft 2 Baro 30.023 Oat 18C1=+17C2= -1C3= (18-ISA) +3CAdd them all and you get +19C. Add ISA and you get +34C That

thanks for sharing with us!!!yahav

I have a registered copy of topcat and love it combined with the PMDG744.its the perfect supplement to this kind of simulation.only problem is topcat themselves have no excess to performance DATA of the MD11 :( if this was solved in house it would have been perfect :( It

Hi, PMDG peopleFirst let me just say thank you for this incredible piece of software! :( I own the combo MD11 installed on a C2D 2.6 GHz machineWith 4 GB of ram an Nvidia GF8800gt cardAnd FS9.1 & FSX sp2Both have great performance!I would like to report one performance issue and one request with your permission (regarding FS9).1. When inserting VOR+CRS in the NAVRAD page with the course displaying on the NDThe simulations frame rate drops from 30fps to 18fps this was tried on ground while taxing2. As the performance information of this aircraft is being kept in secrecyAnd it is pretty much impossible to get ones hands on the required information to plan a safe flight, how about creating a simple takeoff calculator for runway length speeds and assumed temperatureBasically the all ready existing FMS program of the MD11Just with a different interface that would allow printing basic loading and performance information. It just feels weird guessing required takeoff run lengthWhen one is seating behind the controls of the most advanced airline simulation in the universe! :( Thanks! Yahav Lipinski

Hi all,1. Time acceleration in CRZ, Is it possible with out upsetting the program?2. The program does not allow me to use the (1 & 2) keys with the default "shift p" Push-back feature. Can any thing be done?3. Is it possible to request "direct to" from the controller?They should put this program on the MSFS "system requirements" list.This program really does enhance the simulation experience!thanks.yahav

nothing about reinstalling on a new coputer in the FAQ :-hmmm

Just bought a new computer!How do I reinstall PMDG 747?
