Autopilot and Radio explainations

<< < (12/12)

Gdex:
I can’t seem to be able to have both ATTH and either HSEL or NAV on at the same time. For example, if the A/P is on HSEL, and I manually adjust the pitch and throttle to get the climbing rate I want, then when I click on ATTH so that the A/P will maintain the current attitude, HSEL goes off. The same thing happens if I use CPL (to NAV) instead of HSEL. Has anyone run into this problem? Any solution?

JANDMBEAR:
I'm still confused as well. And as I have read the "first post".....I guess I need to read and re-read until I understand it. This is how it seems to me anyway

There is a problem, sometimes, with the radio system. If you just plug in the TACAN numbers, IE: 57 in this example, the radio system misinterperts it, and set's the wrong freq.
There are two ways to solve it. One is to pause, "Select Aircraft" to the default Cessna 172 or something similar, call up the radio stack, set the freq you want on NAV1 Active, then "Select Aircraft" back to the F/A-18.
The other way, that I always use, is to Select TACAN on the UFC, and punch in the frequency that is equivalent to the TACAN you want. Let us say 115.10, just for an example. Punch the entire freq into the scratchpad, for this example 1-1-5-1-0, then hit Enter. It should then display the proper TACAN number you want, in this case, 57X. Make sure you use the entire freq number or it gets confused, sometimes.
OH! a possible 3rd alternative, I apologize: You can add a pop-up radio panel to the plane's 2D cockpit from a default plane, again like hte C172, just for example. Then you pop it up, set your frequency, say 115.00 for example, in the NAV1 Active portion of it, and it will then display the proper TACAN number, say 57X.

There is an add-on scenery for Coupeville, near Whidby Island, specifically for FCLP practice, that has 2 TACAN frequencies you can switch between just by switching the TACAN from TTX to TTY (TT=TACAN number I don't remember :D ) by pushing the button beside the X or Y on the UFC once the frequency is entered. So you can have either a TACAN only approach using the IFOLS, or an ILS approachusing the ILS Needles on the HUD. If it's set up for ILS on the HUD Control Panel, naturally.

And just so you know, I think, although rarely, that the Nimitz (Numb-Nuts, we used to call it) is 47X, or 114.00. Or maybe 57X, or 115.00. Do you see a pattern here? :D

NOT in TACPAC, btw, just with the Jivko Rusev HUD, Which is awesome, and can be put into any plane. Heck, I put it into a C172 just for fun! And with the moving, or mobile versions of carriers, not the "static" or scenery add-on boats. AICarriers.NET is what I use to make them mobile. There are any number of sailing plans for different carriers, aside from the one default one in the Game.

Moving on to the ATC system: With all of Jimi's add-on birds, at least since the v12.1 and up, the FCS can be set to the autothrottle system using SHFT+R, not CTRL+R. That is (was?) to set the current speed into the old autopilot system, before activating the Speed Hold function with SHFT+R, the Sim used. Jimi (and Mr. Orion!!) have set it up so that if you have the ATC engaged, it will try to maintain a) the current speed, if in UA mode, or b) the proper AOA for the plane's current total weight if in PA mode. It doesn't function with Heading Hold, Alt Hold, or APP Mode set into autopilot. IE: you can have EITHER ATC or the other modes engaged.

BTW: For normal landings, with normal landing weights, whether on a boat or ashore, make sure you set the pitch trim to 8.1 for the correct AOA when in PA mode. Gear down, Flaps 2 (full flaps). When you either change the pitch, or when you first enter PA mode, it will display on the lower right side of the HUD for 5 seconds.

I hope all my babbling helps a little bit...
Have great flights, and great days, all!

The Shift+R shortcut (or more specifically, the AUTO_THROTTLE_ARM event; if you remap the event your new key mapping will be used) is masked/overridden in the FSXBA Hornet; the default autopilot doesn't even see the event getting triggered anymore.  The automatic throttle control modes (cruise mode and approach mode) in the FSXBA Hornet are independent of up and away and powered approach; see this post (http://www.fsdreamteam.com/forum/index.php/topic,6944.msg94148.html#msg94148) for details.  As of the current FSXBA Hornet 16.1 version, automatic throttle control should remain on regardless of whether the default autopilot is engaged or not.

Ahh! I apologize. I hadn't gotten to the very latest yet. I'm working on the RTWR for the FlightSim team.
Thank you Mr. Orion, sir!
