"The optimum difference between the FPV and airplane attitude is 5 degrees. If it is more, you need to select flaps."
Now I know what was wrong with my NG over 10 years of operating. And there was me tolerating 2.5/3.0 degress NU attitude in level cruising flight!
Funny the F/O never ever suggested I lower flap to correct this wierd anomaly, maybe they were afraid of upsetting a grumpy old fart??!!
Newbies, please be wary of what you read in these pages. Whomsoever came up with this rubbish should try getting some real experience before pontificating on the topic of attitude flying.
I thought this was the "Professional"/"Flight Deck" forum??!!
