Stability and Control characteristics of the Early Mark Spitfires

[Crumpp]

They are simply warnings, not an indication of a particular dangerous characteristic....you know like 'always wear safety glasses'

Completely, absolutely, utterly false and extremely dangerous attitude.

Engineering tolerances are naturally tight due to the physics of flight. The POH instructions are part of the airworthiness of the design.

In the famous 100 Octane thread, I posted the convention that makes compliance a legal issue. The Operating Instructions carry the weight of law from the aviation authority of the convention signer. Only by explicit instruction is deviation authorized. An example of that explicit instruction is found in the RAF General Pilot's Operating Notes.

Statistically, deviation from those instruction is a factor in the vast majority of aviation accidents whether the deviation, such as the allowance for combat in the RAF General Pilot's Notes, is authorized or not.


All of this is off topic. Start another thread if you want to discuss POH compliance issues.
