Chapter 7 Launch 7 Flight Maneuvers

Question 1

Boxing the wake

Answer 1

1. Let tow plane know
2. Do it outside of traffic pattern at > 1000’ AGL
3. Use rudders to hold corners - avoid slack

Question 2

How do you position glider for unassisted launch?

Answer 2

Position down wing behind the upper wing (angled 20 degrees from centerline) so the tow will pull the glider into alignment and move the down wing first to give it lift.

Question 3

What are the points on the runway?

Answer 3

Aim point is where you aim to touchdown with your glide path.
Initial Point is your actual touchdown point after you flair.

Question 4

Adjust landing speed with ….?

Answer 4

Pitch (Trim)

Question 5

Adjust landing spot with…?

Answer 5

Airbrakes / spoilers

Question 6

What elevation does the roundout start?

Answer 6

5 - 10’

Question 7

How do sideloads on main wheel occur?

Answer 7

Sideloads occur when the glider is not aligned with the direction it is traveling.

Question 8

How is rollout direction controlled?

Answer 8

With the rudder. However once the tail wheel is on the ground the rudder has little effect.

Question 9

Rollout requirements

Answer 9

Wings level
Direction control with rudder.
Back pressure on stick
Airbrakes deployed
Wheel brakes if necessary
Try to get off of runway.

Question 10

What happens if the tail wheel is forced into the ground on landing?

Answer 10

Directional control with the rudder becomes less effective. Pitch forward to take load off of tail and allow rudder control

Question 11

How are crosswind landings handled?

Answer 11

1. Line up tracking with sideslip.
2. Crab to stay lined with runway
3. Straighten crab with runway just prior to touchdown.

Question 12

Difference between side slip and forward slip?

Answer 12

Forward Slip = Roll and opposite rudder to maintain straight track.
Side Slip = Roll and slight opposite rudder to prevent rotating of heading

Question 13

What does down wind landing do to landing speed?

Answer 13

Maintain normal IAS but ground speed will be faster.

Question 14

How is rollout distance affected by downwind?

Answer 14

Distance increases as the square of the ground speed distance. Doubling groundspeed will increase landing distance by 4x.

Question 15

What is the slope of a headwind vs downwind landing?

Answer 15

Headwind will be a steep slope. Approach leg should be shorter.
Tailwind will be a shallow approach. Approach leg should be longer.

Question 16

How should airbrakes be applied at touchdown in a downwind landing?

Answer 16

Full airbrakes and aggressive wheel brakes

Question 17

What steps should be done upon completion of landing?

Answer 17

1. Move glider off of runway
2. Put weight on wingtip or tie it down
3. Close Canopy & cover
4. Install control locks
5. Cover pitot tubes

Question 18

Hangar Storage requirements

Answer 18

1. Chock wheels
2. Weight on wing or wing dollies

Question 19

What happens to roll at different bank angles?

Answer 19

Less than 20 degrees glider want to roll back to wings level.
20 - 45 degrees glider tends to stay there with stick neutral
> 45 degrees glider wants to continue rolling. Requires opposite stick
Diff in wind speed over each wing determines tendency

Question 20

What should ALWAYS be done prior to turning

Answer 20

Clear the airspace

Question 21

What causes adverse yaw?

Answer 21

Initial roll creates more lift and more induced drag on the upper wing. Drag pulls upper wing back.

Question 22

A slip has too much ______ and not enough ——–?

Answer 22

Too much roll and not enough rudder. Yaw string goes to opposite side outside of turn.

Question 23

A skid has too much ____ and not enough _____?

Answer 23

Too much rudder and not enough roll. Yaw string goes in direction inside of turn.

Question 24

When rolling into a turn, the glider has a tendency to pitch ____?

Answer 24

Down

Question 25

What is the relationship of bank angle to load factor and stall speed?

Answer 25

30 bank = 1.2X LF = 1.1X SS
45 bank = 1.4X LF = 1.4X SS
60 bank = 2.0X LF = 1.4X SS

Question 26

Signs of impending stall?

Answer 26

Eyes - pitch up attitude
Ears - lower wind noise
Gut -
Butt - Weightlessness
Mushy controls
yaw string erratic movement
Wing buffetting

Question 27

Stall recovery

Answer 27

1. Sight pitch forward to regain speed
2. Gradually pull stick back to get back to appropriate speed

Question 28

What AGL should be practiced at?

Answer 28

Recovery by 1500’ AGL & within landing strip.

Question 29

What part of wing does stall occur first?

Answer 29

At root, allowing ailerons to still function.

Question 30

What are the two types of advanced stalls?

Answer 30

Secondary - trying to recover too quickly from an initial stall.
Accelerated - (maneuver stalls) speed is too slow for load factor. Cross control scenario. Skidding. happens quickly. leads to spin.

Question 31

What speed is best to stay in the air the longest period of time?

Answer 31

Min sink.

Question 32

What speed is best to fly too btain the most distance?

Answer 32

Best L/D

Question 33

What happens to a polar graph if the glider is loaded with ballast?

Answer 33

It moves down and too the right. Min Sink increases. Best L/D speed increases.

Question 34

Min sink airspeed is based on what?

Answer 34

calm air, level & straight , flaps at 0 degreesflight, air brakes closed

Question 35

What airspeed should you fly in a thermal?

Answer 35

Min sink appropriate for bank angle.
