Stability and Control characteristics of the Early Mark Spitfires

@ JTD

i'm not posting for your private tutoring.

@Sandstone

that is not mutually exclusive, i would believe that the more ham-fisted students would find themselves assigned to a Hurricane squadron or even BC.

You would believe wrong.

Sorry, i didn't know that you are that old to be participating on the selection process then.
But please enlighten us all with your first hand knowledge.

Oh so if I didn't happen to be participant of the Battle of Britain I have no reason to point out that your opinion is wrong (with all due respect)?

/On the other hand, some other people in this thread would say my precious memories are just anecdotes anyway and they would prefer some piece of paper with a graph drawn on it /

robtek I understand what you're saying, but you are wrong that pilots were selected for Hurris or Spits on the criteria of ham-fistness.

My uncle was training on Seafires when the war ended. Us boys grilled pretty good on the a/c and never once did he mention the elevator was a problem like some are trying to do.

Little jump start for that list, a certainly extreme example:
- F4U with CoG at .334 MAC, trim 1.7° up (neutral at 300 mph, 8500ft): 0in stick travel and 5lbs push force to maintain 5.5g in a steady turn.

Anyway, I got no time for this. Whoever may be interested in getting it right instead of having the last word and discrediting others can certainly dig up more data on his/her own.

So you are saying that when a F4U at 300mph in level flight at 8500ft is banked it will make a 5.5 g turn without any pilot input except aileron for the banking
and 5 lbs forward pressure on the stick to keep the stick in neutral position?
If so, the plane is trimmed wrong for this turn.

To have a relation to the stick forces the planes should do a similar maneuvre , like a pull up, without airplane specific quirks, as the automatic 5.5g turn surely is one.

In the pull up the Spitfire with normal CoG and cruise speed needs three quarters of a inch stick travel with about 6lbs pull force to have a three g pull up.

I would be interested in the values of other planes in a similar set up.

I'm pretty sure the Spitfire values are pretty unique here.

If they were that ham fisted, they didn't survive the Harvard.

Bomber Command had the first choice of the pilots. Apart from 1940/2 when training would cream off the best to be trained as instructors.

interestingly Germany had a similar problem with Bomber Units having the first choice of pilots and almost a monopoly on staff officers
