Some FSX Questions

Sun Jun 29, 2008 1:40 pm

Hey there,

first question:

Is it me, or is it the mooney bravo that provides damn bad sight over the front panel therewith limiting runway sight at landing badly?

second:

I took a 738 at Darmstadt AAF (Z11N - I think) and performed a full flaps, full thrust (110%N1) (spooling up with appield brakes) takeoff with full pax but only 35% fuel load take-off and did manage to get of the ground close to the end of the VERY short runway (3000feet?!).

Is that the proper technique to take-off from very short fields?
Is this runway perfomance realistic?

third:

I made a left 180 and returned to Darmstadt AAF landing the 738 using maybe only half of the runway with approach speed near 140kts, full flaps, spoilers and full thrust reverser...

is a that realistic?

Use SHIFT+ENTER to raise the viewpoint for better visibility over the panel. Keep in mind visibility can be limited in real aircraft, and in the flare you don't really have much forward visibility at all.

Full flaps takeoffs on not authorized on most aircraft. There are a number of issues here, including engine out performance (at slow airspeeds, the flight controls do not have the authority to overcome asymmetric thrust in the event of an engine failure) and second stage climb performance (flaps create a lot of drag, and though you get off the ground faster, you can't climb as quickly with full flaps--a major issue if there is terrain ahead).

110% is higher than any setting I've heard of being used, someone with 737 experience may be able to confirm just how high engines can be set.

All in all, the 737 probably would need a bit more than 3000 feet in a realistic takeoff configuration, but it is no slouch.

See page 202 for standard day runway requirements. Remember, actual roll will be less than the required runway.

Then just sit a bit higher and then you have clear visibility of the whole runway ahead of you. At least I have in my MD11F Big grin

under special conditions and some aircrafts it is possible. I remember a take off in an B738 on a GreeK island. It was a full thrust take off and we had 106.3% N1 and on the MD11F the highest I have seen was 110% N1 for take off thrust.
On the other hand on the B737-300/500 I never saw more than 95% N1  Wink

The take off and landing performance of the 737 is pretty impressive for sure. The max flap setting for 737NG is 25°. On the older ones only 15°. higher flapsetting just produce more drag than lift. So you would have a worse lift drag ratio and you don't want that on take off. Advancing the throttles to full thrust and holding the brake is something we call "static take off" and if performed from time to time. It's nice, engine spooling up to take off thrust, you hold the brakes and then release them and off we go.
And the brakes are impressive as well. My shortest landing in the 737-500 was a landing distance of about 800m. Ok, there were no Passenger on board and we weren't very heavy, but these 800m weren't from touchdown, they were from the threshold down to taxi speed of about 10 knots. And a shorter way would've been possible  Wink

Just confirm you didn't touch down short, in the grass.  Smile

Nope, somewhere between the threshold and the 1000' marker on the runway. So in the touchdown zone  Wink

And the 737 is capable of a lot. She is a great airplane....

Sadly, on the type of aircraft I fly (mainly complex singles these days) you tend to get unwanted yoke/knee interaction with the seat too high.

Ah, that counts, then! I was going to say my shortest ever landing (in FS, of course) was even shorter than that - I didn't even reach the start of the runway.  Smile

Kind of off topic; but I am having trouble locating disc 4 to my FS 2004, does anyone know where I can get just the single disc or a copy?
