Hooks

I've posted a newer F-5E model. Still no cockpit, and lots more animating and painting to go. I did put a hook on it, and "someguy" and I have been trying to do carrier traps with it, with about a 15% success rate. Oh well, it wasn't meant for carrier ops anyway. Like most Air Force airplanes the hook was only meant for use in catching a departure-end cable. I'll be checking it against the BAK-12, and if it catches that (departure-end) OK then I'll consider the hook done. Also, as someguy noticed, the yaw damper needs to be turned up a bit, or the base yaw stability derivative needs to be increased a bit. Either way.

VX-4 paint for the F-4J

Gary Brown has released a repaint of the F-4J in the colors of Navy Squadron VX-4, "The Evaluators". The squadron was known for their use of the Playboy bunny logo on their airplanes. You can fetch the repainted F-4J at Gary's hangar.

Douglas A-4E Skyhawk

I just started a conversion of a Denis and Daniel da Silva model of the Douglas A-4E Skyhawk. It may be a long time before I can get to it. Is anyone looking for a project? A screenshot of the model as shown in AC3D is posted at the Hangar.

Over G

Some of the Hangar models have an over-g handling system that will cause the model to freeze in position if the airplane is over-g'd. You can regain control by pushing the stick forward. I haven't added this system to all the models because I'm not sure if users will find it desirable, and I'd like feedback on this. Like all systems, you can turn it off by removing the line that activates it from the JSBSim configuration file.

Gun Effects

Last I checked there is no default key or button binding in FlightGear for a trigger, so you have to define your own. I use the trigger on my joystick, which is the most obvious choice. Just modify your joystick configuration to bind the trigger to the property "/controls/armament/trigger". While you're there I recommend binding the "hat" fore/aft axis to "/controls/flight/elevator-trim", which is how a real aircraft stick works anyway.

Nice video of F-4N and Nimitz

"TheFGBlaze" has just posted a nice video of the F-4N model and the carrier Nimitz in FlightGear.

DavePack bug fix

"Jano" discovered a leading-slash bug in DavePack, so this has been fixed now. Thanks Jano! The leading-slash was causing the user's afterburner effect to also appear on other multiplayer airplanes. I also had to include a new JSBSim system, called "ab_workaround", that works around a multiplayer limitation, namely that the afterburner state is not sent over the multiplayer protocol. So far only the F-4J and F-4N have been converted, and I could use some testers. Please let me know if the afterburner animations of these two aircraft work properly over multiplayer.

The AOA lights

Some time in the 1950's the Navy, and later the Air Force, started putting AOA annunciator lights on top of the instrument panel to aid in holding proper angle of attack for landing. The top light tells you your AOA is too low (fast), the middle light tells you you're right on, and the bottom light tells you your AOA is to high (slow). The funny thing is the Navy and Air Force couldn't agree on what colors of light should mean what, so they ended up using different schemes. In the Navy scheme the light colors from top to bottom are green, yellow, red. In the Air force scheme they are yellow, green, red. So, in a Navy jet you want to see a yellow circle displayed while on final approach, and in an Air Force jet you want to see a green circle.

Vigilante Trivia

Did you know the RA-5 Vigilante, shown above in the title graphic, had no rudder, no ailerons, and no elevators? You can amaze your friends with this one! Actually it's a bit of a cheat. Instead of a rudder the entire vertical stabilizer rotated about a point. Same for the horizontal stabilizers, sometimes called "slabs". Instead of elevators the whole slab rotated about a point, which is standard procedure now in supersonic fighters. Instead of ailerons the Vigi used spoilers, with some differential slab movement mixed in. All in all this setup was pretty advanced for the times.

Aerial Refueling

Many of the models have refueling switches. These switches extend the refueling probe (or open the refueling door) and begin the refueling process. A green light on the fuel gauge lets you know that refueling has begun. My airplanes used to honor the air refueling "box" behind the tanker, so that you had to be in position there to refuel. Someone changed this in FlightGear, requiring refuelers to have a nasal script installed in order to honor the box. I've decided not to support this change, so my models can now refuel anywhere. Sorry about that.
