Q

What scenario on taxi can lead to a Nose-tip?

A

Turning away from a headwind.
Hold stick full aft, avoid putting much power at all…
If you added power and now the nose starts tilting down, realease the brakes and add more power to exit the nose-tipping over event.

Q

What issue comes up with Turning downwind?

A

It won’t want to turn, up to Full rudder needed, some brake and some power. Here again it can end-up on its nose…handling will vary with location of Cofg on the day.

Q

Stick full aft on taxi, unless relative wind is from behind and >6kts (like faster than speed we are taxiing and +6kts…why?

A

Stick in your gut puts need weight on the Tail, when more than 6kts tailwind ontop of relative wind, the put Stick forward.

Q

With left quartering tailwind of 10 kts where should the stick be?

A

Top right corner, with tailwind the ailerons are positioned parrallel to wind, so wind hits down deflected aleron 1st, making that upwind wing want to stay down more.

40
Q

Always raise the tail?

A

Slowly and Smoothly

41
Q

Preferred Rudder technique on takeoff?

A

Small and fast Pokes on the Pedals.
You can’t move your leg as fast as your ankle

42
Q

At slow speeds the rudder deflection to correct for a swerve is?

A

Larger

43
Q

In crosswind, could line up on downwind side of runway towards the upwind side?

A

Thus eliminating 10deg of crosswind.

44
Q

When visibility over the nose is restricted best to move head or eyes?

A

Eye movement is better

45
Q

What does having the a/c moving prior to achieving full power do?

A

This will minimize chance of Rocks or Debris being funneled to the Prop.

46
Q

Why do you start the Takeoff with stick fully-back?

A

To be able to conteract left-yaw moment with tailwheel steering as Rudder itself is not effective yet!

47
Q

What type of rudder deflections are required later in takeoff run?

A

Smaller

48
Q

What is the longest amount of time my idle to Full power application should take?

A

Done promptly
2-3 Seconds

49
Q

There is a very narrow window when what may solve the develloping swerve?

A

The application of single brake opposite the swerve
~Reducing power to idle may or may NOT be the best solution depending on the situation…going idle only works <15kts ias (i.e. when rudder is not effective yet) and ground loop would be benign.

50
Q

When a swerve occurs on takeoff above 15kts ias, what should you do with the power?

A

Keep it FULL, adds to rudder effectivess with prop blast on tail and on-going accelleration…

51
Q

What is optimum flap position for Takeoff?

A

Best L/D ratio is flaps parrallel to Full aileron deflection!

52
Q

What is a last ditch manoeuver at higher ias on takeoff roll?

A

Add 1/2 flap (from 1 notch)
Once airborne push forward to stay in Ground Effect
You will get airborne but ROC suffers…

53
Q

If swerving at higher ias, also put stick (ailerons) ‘opposite’ the sverve, to regain wings level…is this the instinctive way?

A

YES

54
Q

By contrast…if swerving at low ias, put stick into direction of ground loop…NOT instinctive…why?

A

Idea is small amount of UP aileron drag will assist in straightening the ground path.
This requires a lot of RAM on my part, but doing so b/c ailerons not yet effective.

55
Q

Do you Rotate a Taildragger at VR?

A

No, you just let it fly off when its ready…

56
Q

What is the difference between Cruise Attitude and Tail low attitude on Takeoff Roll?

A

Less drag if lift tail to a cruise attitude (i.e. lifting it a bit more)

57
Q

What is the most Ball force (centrifugal) I should use in a Swing-Takeoff?

A

1/2 Ball deflection, (i.e. Power up a bit as I reverse course and lineup) this is to avoid overloading my landing gear!

58
Q

What direction must a swing-takeoff turn be always made to?

A

Into wind!
It might require a bit of forward stick to lighten the load on the Tail once the turn begins

59
Q

What is the result of taxiing with a tailwind, sloshing fuel and over-doing the centrifugal Ball force during a swing-takeoff?

A

Limping on one-gear and dragging a wingtip!

60
Q

Main difference between Short-field and Soft-field takeoff?

A

Tail up to accell vs.
Tail Low off a soft-field

61
Q

When taking off from Rocks or Rough terrain what technique is used?

A

Soft-field Takeoff

62
Q

What is assumption of Soft-field takeoff?

A

Surface drag caused by tires is greater than induced drag resulting from higher Angle of attack.
OR
To save wear & tear on the aircraft (rough surface)

63
Q

What consideration comes to mind if Tora limited on Rough Terrain?

A

Use Short-field technique instead of Soft-field technique to get airborne!

64
Q

On rough terrain will aircraft faster on ground or with induced drag on the wing?

A

On the ground, choose the best available path on ground, a/c will accelerate faster with surface friction drag than induced drag.

65
Q

Simplest wag of Rtow performance in ALL CASES?

A

50/70 rule
But never dictates a safe ROC after takeoff, that is different calculation (obstacles? High DA?)

66
Q

After an abort due to <70% Vr by 50% Tora, what can you do?

A

Decrease aircraft weight
Wait for cooler temp
Wait for more headwind

67
Q

True or False Most aicraft accellerate better than they stop?

A

False
So, you could potentially land somewhere that you won’t be able to takeoff from!

68
Q

Above 2000’ agl, what do winds do on Surface weather charts?

A

Winds flow parrallel to isobars

69
Q

True/False Surface winds blow 45 outwards from High and 45 inward on a low pressure?

A

True

70
Q

Wag that determines where Lower pressure is?

A

Face the wind
Extend left arm 45 to my left (good direction, easy)
Right arm extend 135 deg aft it points at Low pressure area, worse wx.

71
Q

Pilots go off Runways and have prop strikes because messing with flaps…true or false?

A

True
Only retract flap setting to point you can ergonomically reach without looking down!
Partial Flap retraction gives more WOW…

72
Q

Taildragger wisdom

A

“Fly the darn thing until it is tied down”

73
Q

It’s not your mistakes that will get you…

A

It’s how you take care of them…do the Go-Around

74
Q

Consider parameters for a Continuous turn from Downwind to touchdown…

A

Need some power on, gives visibility of landing area…Tutor Final turn from Ohead pattern…Bowser?

75
Q

What is a stabilized app?

A

Exact Glideslope you want with stable ias!
Flare with Zero drift
Touchdown within -0 +50’

76
Q

Avoid idle descent to landing…because?

A

Cools engine, not ideal if you then do a Go-Around!
12” of MP is nice…

77
Q

Rod in FPM only varies with?

A

Slope angle chosen and Groundspeed on the day!

78
Q

True or False Flap 1&2 give more lift than drag?

A

True
Then it becomes the opposite!

79
Q

Everytime you take flaps, what do you have todo?

A

Check ias prior, then re-trim nose-up!

80
Q

G-Tolerances are reduced by how much with flaps extended?

A

About a third less G
33%

81
Q

True or False always retract flaps in stages?

A

True
Need to increase Coefficient of lift by increasing AOA or IAS
Re-Trim

82
Q

Whats the difference with a swerve after touchdown at 50 vs 70kts?

A

Speed difference acts to the square of the force…
So you get double or twice as strong a Swerve at high speed…not a good thing!

83
Q

When are ‘S’ turns required on Taxi?

A

Anytime you can’t see over the Nose!
Be moving stick for changes in relative wind on my aircraft with each 90deg iteration!

84
Q

What is the correct liftoff procedure in a 15kts crosswind?

A

Downwind wheel will lift a bit prior to upwind wheel!
So flying on single upwind wheel for a bit

85
Q

Backup for tie-down when remote?

A

-Dig holes in front of main wheels and push in in them (decreases aoa)!
-Tie 2inch wood ontop of my wing as lift spoilers on 1st third of the span from fuselage! To not scratch wing put ontop of clothing.

86
Q

Improvised wing spoilers on ground?

A

Sandbags, Tires, Sugar, Flight bag, sleeping bag, etc…

87
Q

With no aircraft around over short time, what can I do to secure aircraft into wind?

A

Set parking brake of only my ‘upwind’ wheel (single wheel) and let it pivot into wind!

88
Q

What grazing animal will eat Fabric of my plane?

A

Cattle

89
Q

Always leave a Taildragger tiedown when unnattended!

A

Even for a few minutes to use the Toilet.

90
Q

What are best tie-downs?

A

Ropes with some elasticity.

91
Q

Which are the two most important of the three tie-down points?

A

Tail and one wing, then if three ropes do the other wing
Leaving tail untied will allow a/c to flipover!

92
Q

If you only have two points to tie down?

A

Tail and one Wing!

93
Q

What rating on your tie-down rope?

A

3000lbs or more
-Nylon 3/8 inch
-Twisted Dacron 3/8 or 7/16th
(Twisted is stronger than braided)
-Polypropylene rope (yellow) is harder to make knots with so not preferred.

94
Q

Best non-slipping knot to secure my aircraft?
Best knot to secure my rope to the anchor?

A

-Locking Half-Hitch then 6” lower a Double Half-hitch
-Bowline (because easy to untie), it will not slip or slide.

95
Q

How much movement should occur after I tie down my aircraft?

A

1-2inches, rocking a bit is good.
Tie-off ends so they don’t wip a/c

96
Q

Do you need to put Chocks when a/c is tied?

A

Yes, you should

97
Q

Should you set Parking brake after hard use or a hot day of taxiing?

A

No
You might blowout O-rings and seals of master cylinder.

98
Q

Why do you tie the flight controls?

A

To avoid them banging against their stops!
If you expect really big winds, tie both front and backseat sticks with seatbelts.
