AS a newbiue sick a emptiing lead into thin air, I have deicided to study as much as possible on line. Luckily I found this great place and then SimHQ and Andy's great missives. Thank all you guys so much for taking the time to put this info out there. I hope my ignorance doesn't pester you guy but I have a question.
ON Sim HQ, Andy writes as follows:
"Angle off. This refers to the relative headings of the fighter and its target. Angle off is simply the difference in the direction the two aircraft are pointing. If they are pointing in the same direction, the angle off is zero…if they are approaching head on, then the angle off is 180 degrees. Angle off is a measurement of heading.
Aspect angle. This term is a measurement of position. The heading of the attacker relative to the target is irrelevant. Aspect angle refers to the attacker and is measured using the target as the reference. This measurement originates at the target’s six o’clock. This is the zero aspect position. The twelve o’clock position off the target’s nose is the 180 degree aspect position. From the six o’clock position to the twelve o’clock, aspect angles are referred to as either ‘right’ or ‘left.’ This is in reference to what side of the target you as the attacker are looking at. If you are looking at the target from its 3 o’clock position, you have a 90 Right aspect. And if you are looking at the target from its 7:30 position, you have a 45 Left aspect. Remember, your heading is not included in this term. Aspect angle is only a way of defining your position relative to the target."
Then, he shows an Image, (No. 8 in the SimHQ lesson guns1.html) with an aircraft attacker positioned at the target 9 O'clock position. The image says that this represents an aspect angle of Left 135. I get the Left part, but it seems that it should be Left 90 aspect angle because you are measuring from the target's tail position 90 degrees.
I don not mean to suggest for a second that the image is wrong, only that I don't understand something. Can anyone help me out with this?
