I have used x-plane on my mac for years now, and having it on the iPhone is awesome. I assume Austin will add more features soon. Won't you, Austin??!

I bought it, and it's way worth it. Of course, I'm an X-plane zealot, but it's great. You don't need a tutorial, it's very simplistic. Just raise throttle and left side, lower flaps, turn off brakes, off you go, lift off, raise your landing gear, raise flaps.

I love it, I'm sure they'll put out updates quickly. If you know anything about X-Plane you'll know they are very pro-customer developers.

don't use flaps in take off!!!!

Yup he's adding,

DUDE.. you have only seen the START.
We are going to have airliners, helicopters, gliders... this is only the BEGINNING.

Also (and there is no way I should mention this) X-Plane AUTOMOTIVE is SCREAMING fun.. I will be ready to release it, hopefully, within 7 days.

When you see me issue a post about how I am morally opposed (or something) to an automotive version of x-plane with ferraris and corvettes and KRAZY tracks, you will know that we are within about 48 hours of release.

I hope to have it for desktop AND iphone shortly!

austin
And also about the next update

...oh yah and the next (FREE) update to the iphone version will have a handful or airports, not just LOWI

So you push the flaps bar all the way down? Or leave it in the default location (on top of the screen). Lowering it down lowers the flaps, which makes you go down . So it makes it harder to take off.

You obviously don't use full flaps, It isn't a very accurate way to use flaps (I'm sure it's fine on the desktop version which has aircraft-specific notches etc..) but I use about 1/4 flaps on take off.

Not quite. Flaps deflect down thus generating additional lift (useful at takeoff given additional weight of fuel) although the primary purpose for flaps is to reduce landing speeds.

You don't need as much flap at take off as TO speeds tend to be faster than landing speeds, and lift is related to the square of velocity.

Oh, ok ;). I don't know that much about flying. Just some sims every now and then. I just used flaps mainly for landing. Thanks for the tip.

I don't no very much about flying either so I'm a newb just like you =]

A SIMPLE (overly simple) rule of thumb is PARTIAL flaps generates more lift than drag and CAN be useful for takeoff. In my Mooney 231 (turbocharged, high performance 4 seater) I use 10 degrees of flaps in take off (shortens take off run, especially at high density altitudes) and once I get 100ft off the field I retract them (positive rate of climb, gear up, 100ft, flaps up)

On landing you want MAXIMUM drag and some increased lift, hence full flaps which creates and excess of drag for the added lift.

Someone who is familiar with Austin, could you make sure he gets a link tot his thread so he knows he has a following that's strong?

Retracted is flaps up. Flaps are extended or lowered partially during takeoff and more fully during landing to primarily increase lift at lower flight speed. They do also have a consequential increase in drag which is more useful in landing.

Some general flap comments.

Flap settings:
  • Flap settings vary based upon the AC being flown.
  • Flap settings also very depending on the type of Take-Off or Landing you are doing.
  • Flap settings are usually expressed in degrees.
  • Retracted --> Fully up. For example, zero degrees flaps.
  • Extended --> Partially or fully extended. For example 10 degrees or 40 degrees flaps.
  • Full Down --> The maximum degree setting. Sometimes pilots will refer to this as maximum flap setting.

Some planes have mechanical flaps. There is a lever like a parking brake that the pilot uses to set the flaps. This mechanical system is very effective for doing some very interesting effects. Due to the nature of mechanical flaps they are limited to small aircraft.

Most airplanes have actuated flaps. The pilot selects a setting and the actuator moves the flaps to the desired setting. This will usually take a few seconds after the pilot changes the setting. This lag exists for both extending or retracting flaps.

Flaps change the effective camber and angle of attack of the wing. When extending or retracting flaps the attitude of the aircraft will vary. For example, when adding flaps (increasing the degrees) the nose of the aircraft will generally drop.

On many aircraft low flap settings are used for Take-Off. For example 10 degrees of flaps. Full flaps are not used for normal Take-Off.

Flaps add drag to the wing. At low settings the additional drag is overcome by lift so there usually is a positive lift effect. At high flap settings the opposite is true. Depending on the aircraft flaps can be used as an air-brake.

There are different types of flaps based upon their construction. Two common types are slotted and fowler flaps. I've attached a picture of a slotted flap.

For those who are not pilots, the next time you fly an airline plane, try to get a seat just behind the wing and you can see how the control surfaces work. It's really fascinating on the large jets like 747s.

On a side note, there is only one simulator that I have tried that did accelerated stalls correctly and that was A-10 Attack.

just a quick note, x-plane 9 v. 9.01 has been submitted by Austin (the developer) to the App Store. It was submitted a few days ago, so it will be available in a few more days probably.

here is a link to the "X-Plane for iPhone" website, which has an interesting article about the story behind X-Plan for iPhone and his trip to Apple HQ to develop it.

This update includes:

Austin (X-Plane Developer) said:
X-Plane 9.01 for iPhone is out now, and has a number of cool improvements over 9.01:

25% frame-rate improvement! I REALLY like the increased fluidity of the sim in 9.01 thanks to this increase.
Calibration screen for phone tilt! One guy writing a review at the AppStore said he likes to fly on the couch, and wants VERTICAL to represent neutral-elevator: Fly on, couch-dude! Just go to the SETTINGS tab in the interface and set any phone angle as neutral! Now you can relax in bed or on the couch, with vertical being the reference-point for neutral-elevator, or sit up holding the phone in your lap with HORIZONTAL being the reference-point for neutral elevator, or anything in between! Set the center-point as you see fit!
Higher-contrast interface! One person said his eyes are a little weaker these days, so we contrasted the interface a bit more to make it easier for all to see! I managed to do this without making the interface look too harsh, I think.

Power and flaps set for you on the final approach selections. One guy writing a review at the AppStore was rather paniced that he had to move his thumbs 1/4" to set the power and flaps on final.. the horror! So, X-Plane now sets 25% power and flaps automatically when you set yourself up in flight, to be more closely configured for your landing! Kind of convenient.
The interface screens are organized a hair differently... much better I think. This lets volume-control and neutral-elevator control be in their own system-config screen, with a different screen dedicated to setting your location! Kind of nicer organization.

thanks for the heads up, that's excellent news, can't wait for 9.01. I loved the read.

I'm surprised that it had to get "approved." I'd expect instant approval for a company that is using their offices.

though I'm happy about the future update I was kind of hoping to see some new planes added, hopefully soon.

i totally agree. the update sounds nice, but i would love to see some new planes or locations if at all possible. I know it will come eventually, because the developer has mentioned more planes in a future update. I'm just not sure how long i can wait! :eek:

He said that he will be adding 2 more planes, not too much longer until this happens he said.
