seaplane taking off

Question 23

The color of a rotating beacon at a seaplane base is?

Answer 23

white/yellow

Question 24

The symbol on a chart for a seaplane base is? Explain the landing direction

Answer 24

an anchor, stock of anchor shows the measured landing direction in the directory

Question 25

What part of the seaplane hull is the most important? Why?

Answer 25

the step, reduces drag while planning and gives a pivot point for takeoff rotation

Question 26

What is the most important part of a pre-flight on a seaplane?

Answer 26

check the bilge for water, may exceed weight and balance

Question 27

What precautions should be taken when docking?

Answer 27

approach slow, have assistants keep the floats and wing from hitting the dock

Question 28

What causes a seaplane to stall?

Answer 28

exceeding the critical angle of attack

Question 29

14 CFR 91.115 states?

Answer 29

aircraft operating on the water shall keep clear of all vessels. Vessels to the other?s right has the right of way, approaching head on pass to the right. Vessel being overtaken has the right of way proceed with regard to limitations of the respective craft.

Question 30

Give 5 sources that a pilot can use to determine if the landing area is open

Answer 30

SPA water landing directory, local seaplane base, local police, corps of engineers, state park authority

Question 31

What are 5 items a pilot will check for on his fly over?

Answer 31

wind direction, water length, depth, surface condition, obstacles, power lines

Question 32

Describe a maximum performance takeoff?

Answer 32

short field/water technique use 15-20 degrees flaps get off the water ASAP - stay in ground effect

Question 33

How many water- tight compartments does this seaplane have?

Answer 33

eight

Question 34

How many compartments can be flooded prior to take off?

Answer 34

Any combination of two

Question 35

Why is proper elevator trim important on takeoff? Water then hard surface?

Answer 35

as the seaplane leaves the water the sudden decrease in water drag may cause a severe pitch up tendency ? There are aerodynamic characteristics on the floats and on land air is under the floats making them more efficient

Question 36

Describe crosswind takeoff and landing methods.

Answer 36

you should use the downwind arc method with the wind and waves on your left

Question 37

Which way will the seaplane turn the tightest on water, left or right? Why?

Answer 37

left, ?p? factor

Question 38

What precautions should be taken when water depth is not known?

Answer 38

use gear down to slow and keep from hitting the hull on any submerged objects

Question 39

Describe the cause and effect of a water loop?

Answer 39

landing wing low, catching a float severely yawing the plane one way then the other, usually destroying the aircraft ? No side load

Question 40

Describe the cause and effect of skipping?

Answer 40

Similar to skipping a stone, wetting too much of the tail section behind the step causing severe drag and suction until buoyancy overcomes it and the seaplane skips out of the water too slow and too high an angle of attack to fly, usually occurs on glassy water or high gross weight takeoffs.

Question 41

The two worst events that can be done in an amphibian are?

Answer 41

Landing in the water gear down or with a low pitch attitude.

Answer 44

a shallow lake has the rougher ?choppy? waves.

Question 45

What part of the pre-landing checklist should we say out loud?

Answer 45

This is a water landing gear up, this is a land landing gear down ?Gear up for Sea and Ski, Gear Down for Ground?

Question 46

Too high a speed on the water will cause what? Why?

Answer 46

Tuck under will occur if you touchdown too fast. The hull is drawn down and thrown up, possibly snapping the seaplane sideways destructively. Water drag increases by the square as the speed across the water increases. The hull speed for this C172 and Baumann floats is 80 kts

Question 47

Perform the run up?

Answer 47

Into the wind

Question 48

additional force placed on the landing gear by

Answer 48

a higher groundspeed at touchdown, it is a seri­ous concern for the seaplane pilot. A small increase in water speed translates into greatly increased water drag as the seaplane touches down, increasing the tendency of the seaplane to nose over.

And additional force/ pounding
