What is the ratio for ball in flight to roll

In flight dynamics a spin is a special category of stall resulting in autorotation uncommanded roll about the aircraft's longitudinal axis and a shallow, rotating, downward path approximately centred on a vertical axis. Spins can be entered intentionally or unintentionally, from any flight attitude if the aircraft has sufficient yaw while at the stall point. It is possible for both wings to stall, but the angle of attack of each wing, and consequently its lift and drag , are different. Either situation causes the aircraft to autorotate toward the stalled wing due to its higher drag and loss of lift. Spins are characterized by high angle of attack, an airspeed below the stall on at least one wing and a shallow descent.

The following is an extract for the Apollo 8 Flight Journal, Day 1. Designers had originally intended to give the crew three separate displays to show their attitude; one each for roll, pitch and yaw. Being pilots, the crews quickly threw out the three displays for a development of the artificial horizon familiar from aircraft instrument panels.

This formula is designed to produce consistent chipping. This system of chipping is to allow the player to use the same technique, but change the club to let the ball perform the required shot. The loft of the club will determine the distance the ball travels through the air as well as along the ground. The higher the loft e. The lower the loft e.

Today I'm going to answer a question sent in by Jerry about chipping and pitching. I'll do my best to explain what Kenny demonstrated in one of our best selling videos to date. Please explain. You must allow popups from this site for the link to work.
