PMDG Forum Rules

1) SIGN YOUR POSTS. Since 1997, we have asked users to sign their real name, first and last, to all posts in the PMDG forum. We do this in order to keep conversations personal and familiar. You took the time to be here, we want to get to know you. This is one of the few rigid rules that we enforce regularly. We do so because we feel that forums in which users must engage one another personally are generally warmer, more collegial and friendly. Posts that are unsigned will be quietly removed without comment by the moderators, so to make your life easy- we recommend enabling your forum signature so that you never need to remember. Do this by clicking the username pull-down at the top right, then selecting "User Settings." You will find the signature editor on the ACCOUNT tab, about half way down the page. Look for "Edit Post Signature." Be sure to click the "Show Signatures" box.

2) BE NICE. We are all simmers here and no matter our differences of opinion, we share a common love of aviation, computing and simulation. Treat everyone else in the forum with respect even when you disagree. If someone frustrates you, walk away from the conversation or ask for a moderator to get involved. Speaking of Moderators, they prefer not to be treated as "The Thought Police" but if any behavior infringes on the enjoyment of another user or is otherwise considered to be unacceptable in the moderator's judgment, it will be addressed in keeping with our view of ensuring that this forum remains a healthy environment for all simmers.

3) BE LAWFUL: Any behavior that infringes upon the law, such as discussion or solicitation of piracy, threats, intimidation or abuse will be handled unsympathetically by the moderators. Threats and intimidation may, at the moderator's discretion, be provided to law enforcement for handling.

4) BE FACTUAL: When you post, always be factual. Moderators will remove posts that are determined not to be factually accurate.

5) RESPECT COPYRIGHTS: Posting of copyrighted material such as flight manuals owned by Boeing or various airlines is not allowed in this forum. If you have questions related to copyrighted material, please contact a forum moderator for clarification.

6) RESPECT PMDG: We love to hear what you like about our products. We also like to hear what you think can be improved, or what isn't working. Please do tell us and we will always treat your feedback with value. Just be sure to treat the team respectfully, as they do put a significant amount of effort into building and maintaining these great simulation products for you.

7) RESPECT PMDG DEVELOPERS: All of the developers will spend some time here. Given the ratio of developers-to-users, it simply isn't possible for us to answer every post and private message individually. Please know that we do try to read everything, but developer workload is simply too high to manage personal contact with tens-of-thousands of users simultaneously. In most cases, members of the development team will stick to conversations in the forum and will not answer private messages.

8) RESPECT OTHER DEVELOPERS: PMDG has always advocated for a strong development community and we have many friends within this community. Every developer offers something unique that helps to make the simming community larger and more vibrant. We insist that you treat our friends respectfully.

9) RESPECT MODERATORS: Moderators have a tough job, and none of them enjoy having to stomp out negativity. If a moderator has to weigh in to keep a thread peaceful, please respect that effort and refrain from giving the moderator any grief.

10) If you require official support for any of our products please open a support ticket through the support portal, https://support.precisionmanuals.com

11) This forum is designed primarily as a vehicle for the PMDG development team to interact with our customers, and for customers to interact with one another in a manner that is positive, supportive and assists in the general advancement of understanding the simulation and helping to make this and future simulations better. Any other use of this forum is not permitted, including but not limited to discussion of pricing policies, business practices, forum moderating policies, advertising of non-PMDG products, promotion of events, services or products that are not approved in advance by PMDG or any other topic deemed unacceptable by any forum administrator

12) HAVE FUN: This is the whole point of it all.

    Hi Ryan, good to see you around in the forum again.

    This might help. From the manual:

    "My [insertpassenger/VA programhere] is flagging me for
    excessiveV/S:

    A common misconception is that passengers are sensitive to vertical
    speed when they are not. The only dif ference that the passengers would
    note would be that their ears were popping more f requently. The
    departure prof ile is f lown in a pitch-f or-speed mode, where you set the
    throttles on the particular throttlelimit andhold speed through aircraf t
    pitch.At lighter weights, these pitch angles may be considerable.In order
    to reign in some of the thrust f or lower pitch and vertical speed, derates
    may be used."

    I use A pilot's life too and I just accept that 93 is the top score for me. I don't want to derate too much without proper take-off performance calculations. When the EFB comes, maybe.

    Thanks for your reply Ryan. I realize that the scoring may not be up to snuff in real world situations but I'm probably never going to be behind a real yoke (I did sit second seat in a King-Air once and that was awesome) but for entertainment purposes it does add some enjoyment to this old man's life. I will try your recommendations on derating which a user on another forum also touched on but without the benefit of the values you've provided. I'll give that a go and hopefully improve my scoring. Cheers!

    Just to add: I have a lot of learning to do, obviously and I'm probably only touching 30-40% of the available settings in the FMC. I should probably spend more time studying and less time flying so that I can take full advantage of all this plane has to offer but I will do that in small bites as I accumulate the hours in the sim. I'm really amazed at how this plane has captivated me. Prior to purchasing this plane 90% of my flight time was in GA with little interest in Jetliners. Now I've spent 6 solid weeks in this bird and not even considered flying anything else for the time being.

    Daniel,

    Those really aren't realistic limits to "score" an airline pilot on and nothing like that exists in the real world. The airplane is going to require whatever climb pitch attitude it needs to satisfy the selected airspeed at the given thrust setting. While I don't personally think it's worth trying to modify your procedures to do this for the sake of a fake scoring system, the likely way to do so in the climb at least will be by derating the takeoff and climb thrust on the N1 LIMIT page. The 700 is a rocket if you select full takeoff thrust and are at a light to medium load of passengers and fuel (which is typical on short-haul flights). Try TO-1, an assumed temperature of 65C, and CLB-1. (in real life these values are calculated for every individual takeoff, but these ones should work most of the time) You also want to make sure you're actually handling the departure correctly as far as accelerating at the right height, "bugging up" the MCP speed knob to the flap up speed at that point so the aircraft pitches over to accelerate, engaging VNAV SPD for the climb, etc.

    Pitch Axis on Takeoff

    Hey all, I need some help here. I've been flying this bird exclusively since purchasing it about 6 weeks ago and with dozens of hours spent in it I'm still loving it. . I recently purchased A Pilot's Life 2 to add some virtual career enjoyment to my flying and one of the problems I'm having is violating the nose pitch axis on takeoff. The program measures various flight data and then scores you on your overall flight performance. Anything over 20 degrees nose pitch up or 10 degrees down will result in a violation and point loss.

    My problem begins when I engage the A/P. I try and hand fly until I get up over 1000' or more AGL and sometimes I have to ignore the Flight Director indicators in order to stay below the 20 degree indicator (which is very difficult to do) but even if I manage it, the second I switch over to A/P the bird heads for the heavens and it's a 30 degree pitch angle.

    Is there a way to mitigate this in the FMC setup/parameters. I'm importing the F/P over from Simbrief.
