inky160 Posted January 31, 2018 Share Posted January 31, 2018 When an aircraft maintains a 6 or 7 degree nose-up pitch attitude what is the corresponding vertical speed? Looking for a conversion table or is there such a thing. Found a vertical speed chart but how to convert to pitch attitude in degrees.

f16jockey_2 Posted January 31, 2018 Share Posted January 31, 2018 When an aircraft maintains a 6 or 7 degree nose-up pitch attitude what is the corresponding vertical speed? No relation wso. Could be falling like a brick (remember AF 447). Wim Link to comment Share on other sites More sharing options...
mallcott Posted January 31, 2018 Share Posted January 31, 2018 As F16jockey says, no correlation whatsoever. What are you trying to achieve? Without an AoA indicator you will always fly an airspeed, and accept the resulting climb rate and pitch angle based on the aircraft parameters. The other alternative is to fly the desired climb rate and accept the resulting airspeed. One is riskier than the other... The only time pitch angle is considered is for obstacle clearance, which requires specific guidelines in the POH. Link to comment Share on other sites More sharing options...
lnuss Posted January 31, 2018 Share Posted January 31, 2018 Those charts don't address what I think you're asking. They are to let a pilot know what vertical speed he should maintain at a given ground speed in order to stay above rising terrain at a given gradient (feet of terrain rise per nautical mile). This is independent of aircraft, only needing to know groundspeed, but has nothing to do with pitch angle or power setting -- just climb gradient. If I understand your question correctly, there is no chart, as such, for what you are asking, since rate of climb depends on the aircraft, the power setting, the altitude, the temperature and more, in addition to pitch angle. So you can maintain, say, 800 feet per minute at a given power setting with a 6 deg pitch up, but adding power will change the rate of climb, while decreasing the power will reduce the rate of climb -- depending on aircraft and power setting, it's even possible to be descending with a nose up attitude.

inky160 Posted January 31, 2018 Author Share Posted January 31, 2018 I was just looking for a scale that would correlate nose attitude to vertical speed. Graph below shows for a 5 degree nose up attitude correlates to VS about 600FPM. Is this a useful analogy? So, if I set my autopilot for the 600FPM vertical speed, the autopilot would automatically set my nose attitude to about +5 degrees?

mikeandpatty Posted January 31, 2018 Share Posted January 31, 2018 Agree - no correlation. You might be 20 deg nose up with a 4000 fpm rate of DESCENT in a high performance airplane - in an approach to stall but with some elevator and roll authority remaining.

f16jockey_2 Posted January 31, 2018 Share Posted January 31, 2018 Graph below shows for a 5 degree nose up attitude correlates to VS about 600FPM. That's not a graph. It's a G1000 display. Your same twisted analogy (following the red line, I suppose) would also give us 106 kts TAS on the left ? Very funny. Better use IAS btw.

inky160 Posted January 31, 2018 Author Share Posted January 31, 2018 following the red line, I suppose The photoshop edit with arrows was not meant that a line could be drawn straight across the display. Although it sure appears there is coincident with Attitude and VS. Thank you all for comments. I guess it was a pretty dumb question that made no sense. Sorry.
