飞行距离
Also known as: 飞行
飞行距离是指球在首次落地之前，在空中飞行的距离——与包含滚动的总距离不同。
对进攻球的选杆而言，飞行距离是重要的数字，尤其是当球必须越过障碍物、沙坑或粗草区才能到达目标时，或者当落在滚动不可预测的高台果岭上时。与依赖落地区域坚实度和坡度的总距离不同，同一次挥杆的飞行距离在不同球场条件下是一致的。这使它成为进攻球规划中可靠的数字——你要飞越前方沙坑，而不是滚过它。
飞行距离由三个共同作用的因素决定：球速（提供能量）、发射角度（控制弹道弧线），以及旋转率（决定球在减速过程中能维持升力多久）。较高的发射角度配合适当的旋转，能让球在给定球速下在空中停留更久；旋转过多会让弹道气球化，而不增加飞行距离；旋转太少会让球过早下坠。对每一个挥杆速度而言，这三者都有一个能最大化飞行距离的最佳组合，而且因球杆而异——一号木被优化为低旋转、高发射，而挖起杆则受益于更高的旋转以便迅速停球。
对业余球手而言，影响最大、也最被低估的记分改进之一，就是了解每支球杆的准确飞行距离。研究一致表明，业余球手平均高估自己的距离10%到20%——在某一天用“150码球杆”，实际飞行距离却只有130码。结果是反复出现进攻球不足的情况，留下困难的上下果岭，或更糟。花一次训练环节，在发射监测仪上或带有距离标记的练习场上记录球包中每支球杆的飞行距离（而不是总距离），几乎能在每一次进攻球中获得回报。
Take one range session focused entirely on carry. This means hit 10 shots with each club and pace off or note where the ball first lands, not where it stops. The average of those 10 carries is your real planning number. It will likely be shorter than you expect, and using it will cut your short-of-green misses by a lot.
In wind conditions, use the "distance-to-pin plus 10% per club-of-difference" rule as a starting rough adjustment, then refine with launch-monitor data from your session. A more precise approach: for every 10 mph of headwind, add one to two clubs for carry; for tailwinds, subtract about half a club. Altitude also matters — at 5,000 feet, carry increases roughly 10% over sea level due to thinner air.
Example
一记飞行150码、滚动到158码的7号铁杆球，其飞行距离是150码——这是你用来越过前方沙坑的数字。使用158码的总距离会有落进沙坑的风险。
Why it matters
按球杆了解准确的飞行距离，是降低分数最快的方法之一，因为它消除了代价最大的进攻错误：落入障碍物之前。高估飞行距离在业余球手中极为常见。
How it shows up on video
Carry distance cannot be directly measured from video alone. But ball flight shape offers useful clues. This means a high, soft-landing trajectory with moderate spin suggests carry is optimized. A flat, low trajectory or a high balloon suggests spin or launch angle is off, costing carry distance. A launch monitor or measured landing point is needed for the actual number.
Common mistakes
- Using total distance for club selection over hazards — total distance includes roll, which varies by ground firmness. Always use carry for clearance decisions.
- Basing club distances on best shots rather than typical shots. This means actual scoring improvement comes from using the median carry number, not the one perfect shot every few rounds.
- Ignoring wind adjustment. This means headwinds reduce carry by a lot (roughly 1–2 yards of carry per mph of headwind for a mid-iron). Tailwinds add less than most golfers assume (about half as much as headwinds cost).
- Confusing shot height with carry distance — a high-launching shot is not necessarily the longest-carrying one. Too much spin can balloon the ball and reduce carry despite a high peak height.

Frequently asked questions
我如何找出自己实际的飞行距离？
使用发射监测环节，或使用能区分飞行距离与总距离的GPS设备。或者，在无风的日子，在有测量目标的练习场上，记录球首次落地的位置（而不是弹跳和滚动后的位置）。每支球杆打10次，使用中位数，而不是最好的一次。
逆风会减少多少飞行距离？
对中铁杆而言，每英里逆风大约减少1到2码飞行距离。15英里的逆风，根据弹道和旋转的不同，可能损失15到25码飞行距离。旋转更高的击球受风的影响更大。在强逆风中，比平常多用一到两支球杆是一个合理的经验法则。
海拔会改变飞行距离吗？
会。在大约5000英尺海拔，由于空气密度降低，同样的挥杆飞行距离会增加大约10%。在7000英尺（丹佛或山地球场等地常见），增幅可以接近15%。依赖旋转率的击球（高旋转挖起杆）比低旋转的开球受到的影响更大。
