Landing Model Accuracy

Featured Replies

To throw humility to the wind, I'm a pretty good stick ITRW and have more than my share of greased on landings so when I was painting them on in FS9 it seemed right.But I recently flew a new machine..of course before reading the manual...and managed to execute a really lousy final approach, had about a 1,000 fpm decent rate over the numbers, flared and touched down at at least 600 fpm and guess what...CHIRP...no float in ground effect in spite of my excessive speed and no BOUNCE.Tried the same thing in half a dozen default and add-on machines...same thing. I even drove them on at 500 fpm with NO flare and....CHIRP...no bounce.The only machine that I have tested so far that acts pretty correctly is the RA Spitfire.Is there a way to modify to more realistically simulate the landing characteristics?What is needed is:1. A pronounced swoop up in the flair at excessive speeds.2. Foat in ground effect at excessive speeds.3. A BOUNCE if runway contact is made at an excessive decent rate.4. The SOUND of tudding when you hit too hard...and if it's a rental airplane...the sound of the owner screaming at you over the unicom frequency!!!I don't have ALL available aircraft and haven't tested all the ones that I have, so please don't presume that I am attacking any particular machine. There are probably others like the Spit that perform well in the landing phase.Regards,Jim

There must be a way, because the IK DC-9 performs exactly as you describe, with the exception of screams of outrage from the dispatch office. Steve Small did that one, so at least one designer knows what it's all about...DJ

Hi there. Just to add to bouncing aircraft. I 'fly' the default DC-3 a lot and that will bounce really well even if I don't want it to! I think part fo that is coming in really slow 65-70kts with power down and elevators way up and just catching it wrong as it hits the ground!! The passengers are up in the luggage racks generally when I check on them after we stop.Andy.

<>Right, so we know it can be done...I just wonder if there are tweaks we can use to accomplish it??Regards,Jim

Ive had a couple of good bounces in the cj1.

You can modify the damping and compression of landing gear in the aircraft.cfg configuration file which is stored in the a/c's main folder.Damping and compression values are given in columns 9, 10 and 11 of the point.x entries in the [contact_points] section. From the Aircraft Container SDK documentation:"Column 9: Static Compression: This is the distance a landing gear is compressed when the empty aircraft is at rest on the ground (feet). This term defines the

YAAAAAAAAAAHOOOOOOO! BOUNCE is RIGHT!!! But I have messed around and gotten it better than the default but there is just NO float. Book in at 80 knots, 500fpm decent rate...flair to level at about 10 feet and you should experience a MAJOR zoom up out of ground effect...but nothing.But I have a new found respect for those intrepid souls who do the flight models. It must take TONS of time.I presume that most developers don't want to make landing too tough or they would lose customers.I don't mean to rain on anyones parade but I'll bet most of my fellow RW pilots would agree that it ain't NEARLY as easy to execute a smooth, greaser in the RW as it is with most sim flight models where you can just drive it on for a chirp and stick to the runway job.Best,Jim

Jim,The PMDG 737NJ will bounce you all over the place if you make the approach like you said. It has excellent landing characteeristics. The model has been tested by several RW 737 pilots so it is pretty accurate.Bob

 

I have bounced lot's of times. Sometimes, long ago, coming down on the 2 bounce in flames. It's there for most of the aircraft, maybe developers now don't think that it's a priority with all of us ex bouncer experienced pilots out there....billg

I did it for the opposite reason but you might try playing with the "Cruise Lift Scalar" in the .cfg file. I had one airplane that just refused to be landed. You had to come in at way below stall speed and then push it nose down with full nose down trim to get it to go onto the runway. I decreased the Cruise Lift and now it settles perfectly on approach as I cut throttle.Not attacking anyone but I think some designers get caught up in the numbers and don't pay attention to the feel of an airplane. If it climbs at the correct speed, stalls at the right speed and cruises at the publised numbers then they figure it should have the perfect handling characteristics also. Actually I think Microsoft is the worst in this regard. Probably why I don't fly the defaults very often. In reality however even if the numbers are right on, if the airplane is a handful to fly, floats or sinks excessively etc. those numbers don't mean anything.Now if you want a sweet airplane to hand fly (it's payware but worth every penny) try Flight 1's ATR 72-500. That thing can almost land it's self but in my opinion the fancy AP is wasted. It's just way too fun to hand fly approaches.

Thanks Jim. I'm pretty much a piston guy...or turbo prop. It's interesting though, some of the payware machines I fly land very realistically and others, by the SAME developer can be driven on for a chirp and stick landing.And few that I fly model ground effect well if at all. Maybe that's a limitation in FS9 but as every RW pilot knows...esepcially in light singles...if you get low enough for ground effect to occur at too great an airspeed, you are going to do a MAJOR swoop up.Of the equipment I fly, the RA Spitfire is as good as it gets and I'll tell ya what ain't too bad...the default Mooney.If it didn't exist in FS9 and was sold, as is, by one of the popular developers, they would sell a bunch of them.Regards,Jim
