Wind will affect the V1 speed along with available runway length. This is due to runway stopping distance. With a headwind the V1 can be higher as your stopping distance required will be less. Conversely with a tailwind your V1 can be less as your stopping distance required will be longer. V1 can never be higher than VR so if the calculated V1 with the tailwind is 157, the VR can never be lower than this. VR will always be greater or equal to V1. V2 can be influenced based on VR although it's basic calculation is thrust, flap setting and weight. Per the A300 flight training manual "VR = Speed at which rotation is initiated to reach V2 at an altitude of 35 feet by the end of the runway." In the headwind example the V1/VR is delayed and therefore the V2 is likely to be higher as the A300 needs to get to the required 35 foot safety altitude while at the same time it's accelerating. In the tailwind example with the lower V1/VR the V2 is lower as well as it will reach the 35 foot safety altitude at a lower airspeed. The one thing you don't see is the absolute V2 number based only on thrust, flaps and weight. One can only surmise from these calculations in your screenshots that V2 is no less than 162 knots.

Try uninstalling and redownload/reinstalling the A300. Cheers, John (A300 Mechanic (AME))

Yes, you are correct. The ECAM indications should be the same as the analog gauges on the overhead panel. Any comments from iniBuilds? Cheers, John (A300 AME)

I don't have GSX. I was running Navigraph and FSUIPC7. This hasn't happened since but it's only been 3 flights. Thanks, John (A300 AME)

Hi Alan, A300 AME.... I'm a licensed Aircraft Maintenance Engineer (Canada) (A&P in US) working on the A300. AME is an abbreviation and is applicable to Europe as well. Have you tried uninstalling and reinstalling the A300? Could be a corrupt install. Maybe empty out your community folder and try the A300 to eliminate any conflicting add-ons. Just move all of you community folder contents to another folder named xxx community or similar so the sim doesn't recognize it. Regards, John (A300 AME)

The A300/A310 doesn't have a NWS disconnect button. It's all mechanical linkages to the NWS system. There is a spring override system that allows the pilot to hold the steering tiller centered while doing the flight control checks. Regards, John (A300 AME)

Was this on the first time running v1.0.3? I had a couple weird issues on my first load that weren't there on subsequent reloads. Maybe restart the sim and see if that helps. Cheers, John (A300 AME)

It was okay on the second try. I wonder if this is associated with the falling out of the sky issue (just the other way around 😵)? I'm going to do another flight out of CYYC this morning to see if it's still okay. Cheers, John (A300 AME)

v1.0.3 I was doing the final flight plan entries into the Capt's MCDU when all of a sudden the aircraft was tossed into the air like a ragdoll and spinning like a top. This was at CYYC on APU power with engines not running. I'm going to give it another go. John (A300 AME)

Can you expand on what the "auto rudder disconnect" is meant to accomplish in the sim? Thanks, John (A300 AME)

I just click and hold on the bug with my mouse and move it left or right as required with the mouse. Once you've clicked on it you don't have to stay on it to move it. Works very quickly this way. Cheers, John (A300 mechanic)

I would have to guess as at what it does as the documentation is very lacking. Regards, John

Hello, Both engine EGT's indicate 84C when starting a cold flight with a TAT of 15C and an ATIS OAT of 10C. This is at KPMD. The EGT indication system should indicate close to the OAT but will not indicate negative temps. Regards, John (A3001/A310 mechanic)

I've had a few flights on v1.0.3 and have great rudder response on the takeoff roll. Granted I have a response curve set up on the rudder axis through FSUIPC7 that reduces response around the center point. As B320Max8 said. Do you have the "Auto Tiller Disconnect" selected in the EFB? I do and it works fine. Cheers, John (A300/A310 mechanic)

Just finished a successful flight on v1.0.3 and during the shutdown checks, the EMER EXIT LT annunciator does not illuminate with the switch in the disarm position. Thanks, John (A300/A310 Mechanic)

After restarting the sim this seems to have fixed itself. Cheers, John (A300/A310 mechanic)

At this point the MCDU won't allow me to enter V1 and VR speeds. Will reload and try again. Thanks, John

For the sake of seeing what the issue is, I carried on with a normal takeoff and as soon as I hit the TOGA button, my TO page came back but my V1 and VR speeds were deleted. Thanks, John (A300/A310 mechanic)

Hi All, Just trying out the latest v1.0.3 and have just experienced my MCDU dropping all of my TO speeds and information and displaying the APPR page and setting the speed bugs to the APPR speeds. This was while entering the active at KPMD RWY 25 with INI default FDX livery and default scenery. Thanks, John (A300/A310 mechanic)

I can report the same here as well. John (A300/A310 mechanic)

Hello, One peculiar thing I've seen with this sim are the parameters are all matched on the ECAM ENG, BLEED and WHEEL pages. This is highly unrealistic. No 2 engines are the same and will have varying Oil Press, Oil Temps, Oil Qty, Bleed press, Vibes and Fuel pressure. All left and right parameters on the BLEED page are exactly the same. The brake temps are all the same on their respective gear but should all be slightly different. In cruise, they are still showing above 0C. Generally the brake temps will vary by as much as 50C after landing and if landing in a crosswind could be as much as 100C difference between the left and right MLG. Just suggesting to add some variability in the parameters between systems. Thanks, John (A300/A310 mechanic)

Hello, The slats extend and retract speeds are painfully slow. The current speed would be about right if using the green electric hydraulic pump and blue PTU to move them. With the engine hydraulic pumps providing significantly higher flow they are much faster. IRL, the slats will extend from 0 to the Slats 15 position in about 5 seconds and to the Slats 30 position from Slats 15 in about 4 seconds. Regards, John (A300/A310 mechanic)

Hello, I'm a licensed Aircraft Maintenance Engineer qualified on the A300/A310 and would like to provide some input. I see the following on the v1.0.2 update list: v1.0.2 Art Fixes/Changes Fixed - HP VALVE should illuminate red during fire test The HP VALVE switch has to be in the ON position to illuminate the red lights during a fire loop test. With the HP VALVE switch in the OFF position, the red lights will not illuminate during a fire loop test. Also the entire HP VALVE switch face illuminates red and not just the text.
