I now try to explain you because an airplane with inferior climb ability can exploit the Immelman.
Frontal fight between Spad XIII and Fokker DrI.
They are both to quota max.
Both use these manoeuvres:1) straight - Immelman - Straight - they are now again of forehead
2) Immelan - Straight - Straight
Now the Fokker cannot perform anymore the immelman he has already used 2 Chips climb the Spad it still has one of it, it can again perform the Immelman it has 3 chips climb and being behind the Fokker or it forces the Fokker to run away with a dive or to perform a Split S
if, instead,Chips are not earned climb the Fokker is able, if it wants, to continue to frontally face the Spad.We don't consider the fact that aftar 3 consecutive immelman the two pilots would have the ache of stomach and they would have returned home.
Really the error that concerns the manoeuvre Immelman has been confirmed by Andrew Angiolino, I have its mail, and this rule is inserted in the official rules of the BGL, and you/he/she will be used to the ending of the Italian championship that will be held in Modena 27/03/11.
It will be used together to other home rules that I have already posted on the forum
