go to plan and the ability to be able to change your heading as an avoidance manoeuvre
whilst tracking is a survival skill.
Whilst tracking, the most effective way to change your heading is to use your head. Your
heading comes from being symmetrical and the keystone to this symmetry is the head. The
head acts like a rudder but at the front instead of the back. If you are heading towards an
unexpected obstacle, look at clear airspace and point your nose in the direction you want to
go.
Coaching Lesson
The aim of this lesson is to teach:
Tracking Dive
44
Training Aids: The Coach, DVD, Video, Bean Bag, Jumpsuit and Altimeter,
Creepers, Mirror.
Revision: Read through the intro and theory to tracking and heading changes then
talk through the 7 stage track. Also, emergency procedures where appropriate.
Explanation: Explain theory to tracking and the tracking dive.
Demonstration: Using an assistant or a freeze frame of the video, demonstrate the
position as a whole. Break the position into parts and demonstrate
each stage.
Imitation: Student to practice the 7 stage track.
Practice: Practice the skill in reps of 5.
Practice with corrections until proficient.
Practice eyes closed.
Demonstrate: Demonstrate a track turn
Practice: Practice Track Turns. Give corrections as necessary.
Confirmation: The student must first complete two tracking exercises across the
line of flight before attempting track turns.
Go through the whole dive sequence from exit to track off. Confirm
in air coaching signals and emergencies. Re-emphasize altitude
awareness and break off at 5000 feet.
Coaches Notes:
Give the student the plan for the dive and inform them that during the entire skydive they
may not actually see you but tell them that you will be observing.
If the student usually arches during tracking ask the student to lie on their back and assume
the track position. Ask them to lift their legs off the ground 6-8 inches to simulate air
resistance against the legs. The balance between how long you wish the student to remain
in the track, and how many attempts at tracking is down to your judgement.
In Air Coaching
The Tracking Dive
45
Exit
Ask the student which exit they would like to practice next.
Vary the exits from jump to jump.
Give the student time to adjust into the neutral position, ensure the student is in a neutral
position before attempting a new skill, they should be ready by the time you reach
terminal.
In Air Coaching
From a position in front of the student clearly indicate the direction you wish them to track,
this must be at 90 degrees to the aircraft line of flight. The student should then (depending
on the length of the track) go through the 7 stage track. You may need to follow the
student to maintain observation. The student should stop, check alti, and then turn 180
degrees and track back across the line of flight toward you. It may be challenging for you to
provide in air coaching, rather than the student waiting for you to get back to them it may
be better if you complete your coaching in the debrief. This problem will be amplified
when the student attempts track turns.
5000 Feet
Observe the students altitude awareness during the entire skydive. At break off ensure
there is a safe distance between you and the student but continue to observe their track and
deployment making a note of the altitude.
Intro to Dive and Approach a Target
To dive and approach a target or to swoop would normally be performed if you were part of
a large formation load and were one of the last to leave the aircraft. Being the last to leave
46
the aircraft creates a few problems to the skydiver and so requires lots of practice to get it
right which is why it is usually left to the most skilful or experienced skydivers on the load.
If you have inexperience in big ways then it is advisable to be as close to the door as
possible on exit however if you want to challenge yourself, and have more fun, the try
getting further back in the line up.
The first challenge you have when leaving the aircraft, sometime after the formation is the
distance between you and whoever has already left. The distance is both vertical and
horizontal and you should close the vertical distance as much possible before closing the
horizontal although the last few hundred feet can be a combination of the two.
The second challenge when swooping down to a formation is eye contact. We rely heavily
on what we see in FS as a visual reference to where we are in relation to others but when
swooping we may lose sight of who is below us in order to maintain a vertical dive
approach. Because we can’t rely on visual feedback we need to rely on timing and
