Trivial Pursuit

[dynamite dean]

Please tell me so that i am not going mad a nice explanation of "P" factor and why it is called pee factor asymmetric blade effect one and the same...?????

And a definition of a critical engine ???. just done my painful grade II on the twin, passed but with a steaming disussion for my twin lecture on these two easy.... - well it didn't seem like it at the time, any offers would be greatly appreciated.

finally anyone know the word "tristadecaphobia" I got it when we were playing trivial pursuits the other night- never heard of it in my life mate!

thankyou

P factor - Descending blade has a greater angle of attack and thus creates more thrust then the ascending blade - especially at high (wing) angles of attack. Thus with a standard clockwise (from cockpit) rotating (right-turning) prop you tend to get a left yawing tendency in the climb.
P maybe stands for Propellor, I'm not sure.

Critical engine - That engine which if fails will cause the most adverse reduction in controllability. On a standard twin it will be the left engine, on counter-rotating twins (PA34/PA44 etc.) there is no critical engine.

Tristadecaphobia - not a clue.

Hope this helps a bit.

dean,

Re. p-factor - see if you can borrow a copy of "The Compleat Taildragger Pilot" by the late Harvey S Plourde, ISBN 0-9639137-0-0, published privately by his family. There's an appendix which gives a very deatailed mathematical explaination of p-factor - far more detailed than you'd need as a pilot, but it'll answer any questions you've got as long as you can fight your way through the maths!

P - position of centre of thrust

[Brenoch]

What I can´t work out is how you can be excessively afraid of knees and roses..

Or even beeing afraid of beeing afraid, could work out quite nicely if you are very polite: I´m afraid that I´m afraid of beeing afraid..

Would that be a phobiomaniac or a maniophobic?

[Lu Zuckerman]

“P” Factor or Propeller factor: This is the way they taught it when I went through mechanics school way back in 49. The airflow from the propeller is in the form of a vortex, which can impart a sideward force on the vertical fin. To counter this force the vertical fin is offset somewhat generating an aerodynamic force that counters the sideward force generated by the vortex.

You are describing slipstream effect there Lu, not P factor.
