2) Exit practice and hookup procedures:
Perform drill at the aircraft or aircraft mock-up.
Practice the proper hand and foot placement and set up for the exit launch.
Have student practice solo as well as hooked up for realism.
Practice the whole sequence from exit.
3) Sit back drill: (For student comfort)
This drill must be practiced on the ground
Practice with the student’s harness attached to your own to simulate tension.
Have student sit the harness.
4) Steering and flaring the canopy:
Display steering toggles to your student so they understand what they are and how to grasp them. This would best
be done prior to the jump.
Explain how the canopy is steered. Explain how turns are initiated and stopped (no countering necessary), what
position is full flight as well as what flaring is and how it is performed. This may be done during the canopy flight.
5) Landing practice:
If the student is to assist with the landing flare, in-air practice is a must. We recommend at least three good
repetitions.
PRE-FLIGHT GEAR CHECK
A. Student equipment.
B. Tandem Master harness and containers.
A. Student equipment:
Start by checking to see that your student has a proper, tight fitting jumpsuit and any other items they may need
such as a leather helmet, goggles, altimeter and/or gloves. When selecting goggles make sure that they are adjusted
to be very snug. As students tend to leave them looser than practical. Students wearing contact lenses should use
goggles with as few air vents as possible.
Again, check the fitting of the student’s harness to make sure nothing has loosened and that all webbing running
ends are tucked in. Check in the following order.
Upper snap position
Chest strap position and tension
Hip strap & back strap position and tention
Leg strap tension and dead-ends secured
Proper staging of side quick ejectors
B. Tandem Instructor equipment:
Prior to checking the system, select your jumpsuit, helmet, altimeter, goggles and any other accessory items you may
need. When selecting a jumpsuit pick one that is looser in the arms and legs to help give you extra drag. This will
enhance stability with light students and help to eliminate rocking in droguefall. It is recommended that you use a
wrist mount altimeter. Chest-mount altimeters positioned between you and the student will probably not give an
accurate reading.
