If you have a look at experimental data (e.g.andyou will find that min drag for a symmetric aerofoil tends to be a little bit past zero incidence. ...
A few thoughts to add to Stuart's comments. (a) TORA, TODA, ASDA are declared aerodrome runway distances available and are fixed. The relevant num...
A little follow-up information. In respect of the 1% slope matter, I have just been reading a rather old US conference paper on airline operational...
Some follow up on Bob's comments. The 1:60 "rule" is an approximation based on some basic relationships for angles measured in radians. For small...
One would need to have a detailed look at both to see what specific differences exist. However, basically, the two will have much the same capabilit...
Some additional points - (a) significant slope will give you a one-way strip operation - see many examples from PNG (b) probably not going to be...

I was having a reread of this thread and it occurred to me that, while (a) we were talking about the situation for a min Va certification, which p...

Depends on how the question and the associated data is presented. Static data is a major part of the flight test program. The data is summarised an...
First, while I have some engineering background with helos, I don't consider myself to be an expert in any shape or form .... However, you might l...

The NASA report will provide some interesting reading but you will derive better value from reading Gentry's articles. If they are not at the refere...
If you really want to remember formulae (when it is just as easy to figure the relationship out when you need it), you use the form appropriate to wha...
