Teaching Flight Maneuvers Soaring Safety Foundation FIRC Rich Carlson
Basic Teaching Steps • Preparation • Presentation • Application • Review and Evaluation
Common Student Errors • Under/Over controlling • Stress overload • Fixation on a single task • Loss of situational awareness
Necessary Flight Maneuvers • Normal and Crosswind Launch • Straight and Turning flight • Ground Reference • Stalls and Spins • Slips to Landing • Normal and Crosswind Landing • Emergency procedures
Pre-flight Inspection • Before first flight or Before every flight? • Is assembly enough? • Reduce/Eliminate distractions • What should be checked? • Use POH based checklist • Positive Control Check • Reduce or Eliminate distractions
In flight maneuvers • Orientation to airport/runway (upwind) • Determining heading (using landmarks) • Picking the heading for stalls • Turning left or right • Basic glide performance • How much altitude needed to cover 1 mile?
3 X 4 Simple Math Solve for X Find X
Simple Math Solve for X = 5 Find X Here it is 3 X 4
Emergency Procedures • Discuss/demo T.O. Emergencies • PT3 at low/mid/high altitude • Distractions during T.O./Tow • Canopy opening • Bugs, Snakes, Object on runway, etc • Discuss/demo Landing Emergencies • Too low to fly normal pattern • Off-airport landings
Approach & Landing • The Glider Flight Instructor does an excellent job of teaching T.O. Emergency procedures including practicing low altitude rope breaks. • The SSF accident statistics show that this practice has paid off by a low number of PT3 accidents.
Approach & Landing • A review of glider accident statistics shows that over 70% of the accidents occur in the landing phase of flight. • The “Law of Primacy” states that the first thing learned is what is remembered during times of stress.
Approach & Landing • What we teach • Complete the landing checklist • Reach the IP at xxxx ft AGL • Enter the downwind leg and correct for x-wind • Opposite Touchdown point • Turn Base • Turn Final and aim for T.D. point • Use spoilers to control height, elevator to control speed
27 9 5 Kts IP Choose Your Approach Goal is IP?
27 9 5 Kts IP Goal is IP point
Approach & Landing • Major drawback is that primary focus is on reaching the IP. • This technique works well when students plan ahead to reach the IP at the desired altitude. • What happens when this planning breaks down and the student is 1 mile out at 1200 ft and runs into 500 fpm sink?
Approach and Landing • What we really mean • Make sure you control your speed to keep from stalling • Make sure you control your height and position so you reach the intended landing point
27 9 5 Kts IP Choose Your Approach Goal is Touchdown Point?
27 9 5 Kts IP Goal is Touchdown Point

27 9 5 Kts IP Which Approach is Best?
A Goal Orientated Approach • Focus the students’ attention on the landing area • Practice ‘standard’ and ‘non-standard’ approaches but ignore naming the legs • 1st approach ‘standard’ • 2nd approach ‘non-standard’, base/final only • 3rd approach ‘standard’ • 4th approach ‘non-standard’, right vs left pattern • 5th approach ‘standard’ • 6th approach ‘non-standard’, overhead join at mid-field • Review previous approaches and begin naming legs, while maintaining focus on primary goal “Law of Primacy view”
Emergency Procedures • Practice arrival from various directions • Practice left, right, straight-in, downwind approaches • Practice arrival from various altitudes • Demonstrate the effect of constant headwind • Demonstrate the effect of a decreasing headwind
2002 Std Class Nationals http://soaring.aerobatics.ws/LOGS/HomePage.html 12 Pilot’s Landing Traces • Tom Beltz • Walter Cannon • Bob Epp • Chip Garner • Ray Gimmey • Sam Gitner • Gary Itner • Tom Knauff • Baudouin Litt • Liz Schwendler • Ken Sorenson • Tim Wells
Post Flight De-briefing • Essential component of lesson to discuss why this approach was different and how it affected other gliders/pilots • Emphasize the skills you are trying to impart (Judgment Training and problem solving skills)
Determining When to Land • What effect does the wind have on landing?
27 9 Effect of 20 Kt wind Time on Downwind: More, Less, no Change? Altitude loss: More, Less, no Change? 20 Kts
27 9 Effect of 20 Kt wind Time on base: More, Less, no Change? Altitude loss: More, Less, no Change? 20 Kts
27 9 Effect of 20 Kt wind Time on Final: More, Less, no Change? Altitude loss: More, Less, no Change? 20 Kts
27 9 Effect of 20 Kt wind Which path is your student likely to fly? Which path do you want them to fly? 4 20 Kts 3 1 2
Final Approach(No wind) 60 kts @ 500 ft/m decent rate 12:1 glide slope 24 seconds 200 2400
Final Approach(20 Kt Head Wind) 60 kts @ 500 ft/m decent rate 8:1 glide slope 24 seconds 200 2400 1600
Final Approach(20 kt wind shear) 60 kts @ 500 ft/m decent rate Maintain constant speed during approach How much time remains? 200 20 kts 0 kts X Y 2400 1600
Decision Time • With a 20 kt shear, are you likely to • overshoot (into area Y) • undershoot (into area X) • Said another way, what actions do you need to take to reach your intended touchdown point • close the spoilers to extend (undershooting) • open the spoilers to sink faster (overshooting) • Another variation, what will the aim spot do? • move up on the canopy (undershooting) • move down on the canopy (overshooting)
Final Approach(20 Kt Wind Shear) 2 seconds for the glider to stabilize at the new sink rate AOA increases from 0.5o to 5.0o 200 20 kts 0 kts 1017 2400 1600
Final Approach(20 Kt Wind Shear) 3 seconds to accelerate back to 60 Kts Glider nose is 20o below the horizon 200 20 kts 0 kts 1300 2400 1600
Final Approach(20 Kt Wind Shear) Start recovery process after 1 second (at height of 88 ft) 200 20 kts 0 kts 2400 1600 1647
Final Approach(Likely outcome in 3 cases?) No Wind Constant headwind 20 Kt Wind Shear 200 2400 1300 1600
Shear Encounters • When can this happen? • Landing in gusty conditions • Landing area shielded by obstructions • During good thermal conditions
