Generally an interpolation exercise typical of these sorts of charts. Note that one shouldn't extrapolate but interpolation is stock standard grist ...
As a general rule - (a) at planning (ie pre-flight) use the longest runway and nil wind unless - (b) the forecast wind is excessive (crosswind) ...
It sure is great to see you pondering over this stuff and having a go at rationalising it all. However, there are some problems when trying to si...
Probably not a simple answer question. However, longitudinal static stability has to do with the elevator forces which the pilot senses when mainta...
Indeed. The use of fudge factors in certification and operational requirements has a long and illustrious history. 15%, certainly, figures in...
Slopes are problematic as the values quoted are not really relevant to performance analyses. Refer to AIP ERSA Intro 9 at para 21.2for the way ASA ...
Not wishing to engage in argument at all, but a critical reading of the two cited references indicates - (a) [color=blue][i][b]Reading through thi...
[color=blue][i][b]For similar reasons that power required increases with height, wouldn't that mean that thrust required would increase aswell accordi...
Carello has given the usual story from the pilot text books but let's have a look at some real world numbers to get a check on all this theory stuff. ...
Welcome to the world of learning about things aeronautical. Speeds probably give more student engineers and pilots more headaches than anything ATC o...

Slope data is included in ERSA. See, for example,
[color=blue][i][b]Alternate is not included in variable calculation. However, the CPL Performance Supplement states company policy requires it to incl...
I think you've headed off up a blind valley. In effect, you have applied the variable reserve to your fixed reserve .. admirably conservative but no...
Same as an anti-servo tab. See here or here, for example,
