Chapter 8 Emergency Procedures

Question 1

What is PIO?

Answer 1

POI = Pilot Induced Oscillations
Pilot does not account for the delay in control response leading to overcontrolling and hunting to find desired response.

Question 2

What is porpoising?

Answer 2

PIO on landing leading to touchdown - takeoff- touchdown -takeoff ….

Question 3

How to counter POI?

Answer 3

Enter control input and then relax when response starts. Go to neutral before attaining desired response.

Question 4

Takeoff POIs. What response level is required at slow speeds?

Answer 4

Larger input. Tapering off as speed increases.

Question 5

What is the effect of the tow rope length?

Answer 5

Short ropes require quick and frequent control input. Use 200’ length.

Question 6

What effect does crosswind have on take-offs?

Answer 6

Wind on rudder will push front of glider into the wind. Weather vaning. Upwind wing lifts.

Question 7

When should lift off occur?

Answer 7

When glider reaches flying speed. This will be lower than stall speed due to ground effect. Hold glider in ground effect until tow starts climbing then follow climb.

Question 8

What typically happens during lift off?

Answer 8

Quick lift-off due to ground effects followed by descent when ground effect diminishes.

Question 9

How should wings be maintained on take 0ff?

Answer 9

Keep them level. Don’t try to control direction with them while on or close to the ground.

Question 10

What happens when the wing tips touch the ground.

Answer 10

A gound loop will occur where the glider will rotate in the direction of the wing that hits the ground.

Question 11

Why is there a delay in yaw at low speeds on takeoff?

Answer 11

The inertia of the wings wants to keep them going in that direction. Relax rudder once glider starts moving in the desired direction

Question 12

How does towline tension affect pitch?

Answer 12

More tension will cause pitch to increase. Dependent on the location of the hook relative to the longitudinal axis. More prevalent on Cg hooks.

Question 13

What effect can pneumatic tires have take off and landing?

Answer 13

Susceptible to bounce when hitting bumpy terrain.

Question 14

What are the 3 scenarios of tow failure?

Answer 14

1. Sufficient runway to land and stop
2. Landing straight ahead
3. Above 200’ AGL return to field

Question 15

If there is sufficient runway to land and stop, what should the glider do?

Answer 15

Land and roll out to the right of the tow plane.

Question 16

If there is insufficient runway to land and stop, what should the glider do?

Answer 16

Land straight ahead if below 200’. Use airbrakes to reduce landing speed.

Question 17

What should be done if the rope breaks above 200’ AGL?

Answer 17

1. Release rope
2. Turn back to airport (into the wind) with 45 turn.
3. Avoid tow plane
4. Maintain approach speed and coordinated turn.

Question 18

What should be done on rope failure above 800/ AGL?

Answer 18

Cross runway at center if necessary and fly landing circuit

Question 19

Traits of a spin? Track, Stalled? Airspeed, loss of altitude, G force, Controls effectiveness

Answer 19

Track, - Narrow descending
Stalled? - yes both wings
Airspeed, - slowly increasing
loss of altitude, - large
G force, - not high
Controls effectiveness - little

Question 20

Traits of a spiral dive? Track, Stalled? Airspeed, loss of altitude, G force, Controls effectiveness

Answer 20

Track, - Broad circling
Stalled? - maybe
Airspeed, - increasing
loss of altitude, - medium
G force, - high
Controls effectiveness - heavy

Question 21

Why is a slack line dangerous?

Answer 21

Entanglement with glider wing

Question 22

Causes of slack line

Answer 22

Too far out alignment with tow
Tow plane descending quickly
Power reduction by tow
Glider too far inside radius on turn

Question 23

How to correct slack line

Answer 23

Slip
Slow application of airbrake
Avoid sudden take-up

Question 24

What causes a spiral dive?

Answer 24

Low pitch in a steep bank.

Question 25

How to correct a spiral dive?

Answer 25

Reduce bank.
Slowly return pitch to level.

Question 26

What are the steps to a spin recovery?

Answer 26

1. Ailerons neutral
2. Forward stick to break stall
3. Rudder opposite of turn to stop rotation
4. Neutral rudder when rotation stops
5. Slowly pull back on stick

Question 27

How to create a spin?

Answer 27

1. Pitch up - slow speed
2. Full rudder
   May take 2 full turns before spin starts
   Vertical airspeed & rotation rate stabilize.

Question 28

Off field landing AGL heights?

Answer 28

2000’ - Select general area and scan for dangers
1500’ - Select landing area
1000’ - Commit to the approach

Question 29

Things to consider when off field landing?

Answer 29

Wind direction - flags, smoke, water
Slope of land - level first then up slope
Roughness of land
Obstacles - ditches, poles, lines, livestock
Ease of retrieval

Question 30

Off field approach

Answer 30

Slowest speed possible, Aggressive braking

Question 31

Steps for off field landing if uninjured.

Answer 31

1. Personal needs
2. Secure glider
3. Contact retrieval/emergency crew
4. Call 911 is concerned about safety - weather / animals
5. Get GPS coordinates
6. Distress Frequency = 121.5

Question 32

Steps for off field landing if injured.

Answer 32

1. Tend to injury
2. Contact emergency personnel
3. ELT -emergency location transmitter
   cell phone, 121.5, EPRIB
4. Stay with glider
5. Conserve energy
