Is there a way with Funky Trees to determine if the aircraft is moving forward or in reverse?
The reason why I want to know is that when an autogryo stalls in a climb, it's nose doesn't drop like a plane, but instead it tends to fall back /fly backwards, The speedometer tends to stay constant and the aircraft goes from flying at, say 25 mph in normal flight to falling backwards at 25 mph without ever stopping.
This i isn't all that obvious right away from the pilot's seat. Yes if a few seconds the pilot will figure it out, but by then it is harder and will take longer to correct than if if the pilot were alerted right away and could pitch the nose down before the stall.
A similar situation occurs when flaring out during a landing attempt, too. Pull up a little too much and the aircraft stat's flying backwards.
@atgxtg Looks great! A nice, simplistic design with lots of functionality.
@TheFlightGuySP
Thanks again. Oh, and if you want to see what sort of monster you helped to bring into the world: https://www.simpleplanes.com/a/XriRWP/725t-Autogyro
Note- it's a testbed, not a finished design. But it does help to reverse engineer how some things work so as to the desired performance out of a build. Because autogyros are weird.
@atgxtg No problem!
@TheFlightGuySP Yeah that does seem to work, and
<color=#{ IAS>5&(AngleOfSlip>90 | AngleOfSlip<-90) ? "FF0000":"00ff00"}>mph
{round(IAS*2.236936);}
seems to work in the HUD to change the speed from green to red when it stalls. I did reduce the IAS factor as 5m/s is borderline "too late" for this particular build, but the code does the trick.
Thanks, you saved me a lot of work. I was going to try and use the rate of change of the latitude and longitude with trig to get a direction of movement and then compare that to the heading to see if it is moving in the direction it is facing or not.
Your method is a lot simpler! Thanks.
You would probably need to use
AngleOfSlipdata to determine your aircraft's flight direction. Such data would probably work best in a warning light.Perhaps something like this: IAS>5&(AngleOfSlip>90 | AngleOfSlip<-90) ? 1 : 0
The code shown above worked for me when I used it. The code must be put into the input text field of the beacon light using the XML editor.
