Fluorine is more electronegative than phosphorus. The phosphorus is at the apex of a pyramid, the base of the pyramid being an equilateral triangle with a fluorine atom at each vertex. The F-P-F angles are 96 degrees. Each F-P bond contributes to the net dipole moment, as a vector from the P to the F. The net dipole moment is the vector sum of the vectors along the three P-F bonds. If all four ...
I'm curious, for anyone using PF3 along with MSFS 2020 to replace ATC, how are you actually using it? 1. Let PF3 automatically handle all communications between the controller and First Office (just like MSFS 2020 AI first officer). 2. You use the hotkeys to answer ATC. 3. Use another program, su...
But in $\ce {NF3}$ fluorine will pull electrons towards itself therefore the electrons are further comparatively and hence repulsion will be less and so is the bond angle. But in case of $\ce {PF3}$ and $\ce {PH3}$ back bonding is possible in $\ce {PF3}$ therefore it has a larger bond angle .
Hi everyone! I actually bought the Pro Flight Emulator ATC add-on years ago and had been satisfied by the purchase. Now I see that PF3 is really an advanced version of it which is a freeware now. Could anybody jut explain me what are basically the upgradation or simply the differences between PFE...
I'm using PF3 for years and never felt the need to look at anything else. It works reliably both when flying the FBW A320 IFR and for short VFR hops with the C172. There is a learning curve but when you get to understand how PF3 works it takes just a minute to set everything up for your flight. And it can easily be combined with a speech recognition software like VoiceAttack - or Multi Crew ...
I also have used PF3 and Pro-ATC/X but feel that RC4 offers the best all around atc for IFR/airline flying. Another bonus, as Luis mentioned, is the price - RC4 + Meatwater sound files are free! If interested, pm Ray Proudfoot, he's a moderator here at avsim. He will set you up with the necessary link for RC4. Happy flying!
1 It confuses me that many researches pointed out different results about phosphine ligands properties (σ-donor and π-acceptor). Since both phosphine $\ce {PH3}$ and phosphorus trifluoride $\ce {PF3}$ possess similar properties, which one is the better ligand in terms of forming a stronger bond with the center metal atom?
Hi All. So I don't know if this is the wrong forum for this so apologies in advance if it is. In short I learned that PF3 is now freeware and as I wanted to try it out. I install it (not in the program files or X86) and start it up. I enter 999 as the activation code (and make sure that I'm runni...
I've used PF3 for a very long time. It sets me up for leaving the gate, guides me to the runway, handles the flight from departure to a standard approach, then guides me to the gate. It suits this old bloke with its simplicity in operation, and as a bonus, Dave, the developer is always ready to help with any details or problems.
