More noobish questions
« on: April 06, 2009, 06:12:51 PM »
1. The plane comparison charts show a fw190-d9 cruising at 420 mph at 30k
I level out around 35k and after ten minutes I doing a whopping 290 mph.
I turn off combat trim and then reset it after auto-level, have stall limiter off and dropped fuel tank with about 50% fuel left. I cruise with WEP on for another 5 minutes and it makes no difference. I'm still doing 290 mph.

Is the cruising speed referred to here descending?
I set the plane to small descent and after losing 5k I am moving at 410 mph and soon after the plane starts jumping like mad. I reset combat trim and after ten seconds it calms down some still shaky.

How do you make ponies and Fws cruise at the speeds they claim at high alt?
I can cruise faster level at 1k without wep and full load of fuel.

2. Does WEP power build up after it is used up?

3. I don't see any real advantage to disengaging stall limiter.
I take a P38 with SL on and can hang on props at ZERO mph for a few seconds.
Without SL I start falling to the side after 50 mph.

coming down with SL on, I can spin the nose around quickly and turn it fast.
Without SL on I have to slow down or deal with spins.

Ok.

O'm not sure which 190 you are talking about, D-9 or A-8... but for both 35k is far beyond their oprtimum altidude. Not only their top speed will be considerable less than at  30k, but they have lost so much power that getting to their top speed takes very long (and I mean very!)

The 410 mph you saw were probably indicated airspeed - the white needle on your speedometer. At high altitudes, your true airspeed (indicated by red needle) will be much higher. I have the tables not at hand right now, but at 30k, 400mph indicated will be over 600mph true airspeed...

2. Yes, WEP will build up after cooling time.

3. Disabling stall limiter will enable you to fly your plane much closer to the limits. The limiter prevents you from getting too close to your maximum AoA, but that puts you at an disadvantage against a player that has the limiter off. Basically he will be able to pull turns much tighter than you are.

The chart speeds are in True Air Speed.  Your white needle one the altimiter is Indicated Air Speed.   The higher you go (thinner air) the more different those two values will be.  AH has a red indicator on the altimeter to show your TAS.

WEP in AH is limited by engine tempature, regardless of how a planes WEP system worked in real life.  After a "cool down" period you are able to use WEP again.  You can find a list of WEP durations and recharge times here.

Basicly stall limiter ignores your stick input that will cause a stall condition anywhere on your wings.  The problem is that in AH a planes best turn rates and radiuses are done riding the edge of a stall.  You'll never get max turn performance with it enabled, and you won't gain experience learning to ride the edge of controled flight to get the best maneuverability out of your plane.

It could take for ever to get up to full speed that high, nobody really goes that high. Most fightinging happens around 10K and lower. In the senarios they use high alt, but not in the game.

The shaking is the compression setting in. It comes on much quicker at higher alts. Side slipping with the rudder helps slow you down and gets you out of mild ones, trim controls can get you out of total lock ups.

Again most don't fly that high, time is what you need to build the speed, not much air for the prop to work on.

2. Does WEP power build up after it is used up?

I think it does in all planes, but not sure. As the engine cools you can use it again. I seem to remember a number of people complaining that that is not realistic as once the water or nos was used up it was gone.

Stall limiter retards the degrees a second you can pull. So with you having it on and I off I can hit a turn harder and so get ahead of you because you will be limited in how hard you can push it. WIth it off you have to be more carefull of stalls but the advantages out weigh the danger. Combat trim is something else all together. With combat trim on rolling up and over the top of a loop with a 38 gets you kind of stuck in the air. The auto trim tries to trim your nose up as your trying to pull it down so it hinders you more at slow speed maneuvering.  Some people have a joystick switch set aside to flip combat trim on and off. Flick it off to get good slow speed stall maneuvers, and flick it back on when you build up a bit of speed again.

dropped fuel tank

I can't believe no one has said this yet...

The rack for the drop tank slows you down.  Don't take one unless you really need it.

Thanks for the speedy replies. I didn't know about TAS and IAS.
I'm still unsure what the difference is. Why does it show IAS if you TAS is much higher?

When I moving at IAS 290 that is what it feels like I doing. I feel like a tortoise.

I took the pony and 190-d9 to 30k to practice bombing hunting at factories.
When I played long ago there was a need to stop those bombers.



I guess I am pulling loops too tight in the p38.
And downward spirals often turns to spins.



There is so much to learn on this game.
I have a hard time strafing ACK with 8 50-cal guns but any plane with canons is a snap.


Is it possible to take a airfield alone in the offline scenario?
Vehicle fields are simple.

Lift force (ergo physics of flight) are made possible by differing air pressures above and below your wing.  Thinner air means you have less air mass to work with to keep your plane flying.  IAS is measured from the outside air pressure, and is important to your actual flying in regards to stall speeds and your ability to maneuver.  TAS is how fast you're really going and is really only relevent to navigation or predicting your flight time to a destination.


Edit:  Lusche posted between the time I previewed my post, and had fixed my link tags.  Who says snails are slow?  :)

Cannon rounds are filled with explosives, and have a small blast radius (you only have to hit close to the target to do damage).  With machine guns you actually have to hit the target, and that skinny little ack gun is not that big of a target when you're in the air.

I noticed even in a tank I had to get near the ack gun to get those bullets on ack.


Now if I can learn to fly that PJ like you do!    :D

HE (high explosive) rounds have to only get near the gun, AP (armor piercing) you, again, have to hit it directly.
