Py Table
Hi Guys
My last question of the day, I promise A/c has 5FP Move to use At 30 degrees C/D two of the six options on the Py Table for a 5 FP Move are: 1. 250 feet of altitude and 5HFP 2. But at 200 feet of altitude the max HFP is 4 (4HFP/1VFP) Can someone explain to me how an a/c with 5FP Move can fly FURTHER horizontally when it's climbing higher/steeper? This doesn't seem to follow the hypotenuse model? Am I missing something? Please bear in mind that I am neither a physicist, mathematician or engineer. Just a simple historian ;-) Cheers Drew |

RE: Py Table
Hi Drew,
With a FP Move of 5 only the boxes with a "5" may be chosen in the nose arc, in this case 30 degree. I think you are using the "5" column with 4 FP Move. All the "4" boxes in the 200 ft line all the Horizontal FPs are equal to or less than 4, the allowable HFPs are 3H or 4H. The number of vertical flight points are determined by VFPs = FP Move - HFP. In (2) above the aircraft has 4 HFPs and may not use any boxes with a "5". Does this help or is more information needed? Cheers, Steve |

It's harder sometimes to explain it than face to face My query is with a 5FP move the aircraft can fly 5HFP and gain or lose 250 feet, but if the a/c only gains or loses 200 feet it can only travel 4 HFP How can an aircraft that is climbing or diving further, and therefore steeper, travel further horizontally than the same aircraft climbing or diving 50 feet less I hope what I am trying to describe makes sense to you?

RE: Py Table
Hi Drew,
I understand about the internet not being easy for questions and explanations. We'' keep at it until I get it ;-) I see the point on the Py-Table you are referring to. Looks like a typo and the "4" should be a 5, the altitude change of 50 ft should make the adjacent leg (on the x axis) shorter. I will post an errata on this and an updated Py-Table. There are a lot of entries to check ;-) Cheers, Steve |
