23
Q

Max G Force load in general, flaps and gear extended too?

A

+2.5G and -1G “ Flaps Extended or Landing Gear Extended 2.0G both”

24
Q

VMCL Speed? “Lower speed in Landing Config”

A

Flaps 15 = 91 KIAS Flaps 30 = 89 KIAS

25
Q

Takeoff and Landing Tail Wind limitation?

A

15 KT

26
Q

Maximum Cross-wind in takeoff and landing?

A

Takeoff 45kt Landing 38kt

27
Q

Refueling Max Pressure in PSI?

A

50 PSI

28
Q

Max Fuel Imbalance on both tanks?

A

1212 Lbs

29
Q

Minimum Height for AP engagement?

A

100ft

30
Q

Minimum Height for using AP and YD except for Takeoff, Go-around and Approach?

A

1000ft

31
Q

VS and IAS use Altitude Limitation during approach?

A

160ft

32
Q

CAT 1 Approach mode Altitude Limitation during approach?

A

160ft

33
Q

Which engine on the ATR42-320 is the critical engine?

A

Left Engine

34
Q

What is the VMCG and VMCA?

A

It’s not a fixed speed. Must be calculated

35
Q

What is VMCL? What is the procedure? What is the speed for Flaps 15 and 30?

A

VMCL is the Minimum Control Speed During Approach and Landing. On VMCL to start a turn into the good engine you need at least 20° bank angle and it takes approximately 5 seconds to start turning. VMCL Flaps 15 = 91kt VMCL Flaps 30 = 89Kts

36
Q

What is the VMLB Minimum Maneuvering Speed Low Bank? What is the bug colour on the ASI?

A

Limited Bank Angle of 15° for a certain speed according to the current aircraft weight.
This one is set on the White Bug

37
Q

What is VGA speed?

A

Minimum speed to perform maneuvering during a go-around maneuvering
VGA = VmHB + 5kt or 1.1 x VMCA whichever is higher

38
Q

What is the Vapp?

A

Final Approach speed in landing configuration + Winds correction speed

39
Q

What is Vref?

A

Referencia Landing Speed
Consider Landing Configuration, Gear Down + Flaps 30° at Final Approach.

40
Q

What is the appropriate NP Propeller setting during the Climb phase?

A

Set 86.3NP initially. When TQR reduces below 75%, set 77.3NP

41
Q

About Max Torque calculation, which phases are mandatory to calculate max torque?

A

Takeoff and Go-around. The other phases we just calculate to cross-check if FDAU is working properly.

42
Q

Which are the temperatures considered Atmospheric Icing Conditions?

A

On Ground = OAT +5 or below with visible moisture
In-flight = TAT +7 or below with visible moisture

43
Q

Which are the temperatures and conditions considered Ground Icing Conditions?

A

OAT +5 or below with Standing water, Snow, Rain, or Slush when operating on TWY, RWY, or Ramp.

44
Q

What is Decelerating Height? How is the calculation?

A

Altitude to start decelerating from 240Kts to VAPP
86NP = IAS x 10
77NP = IAS x 10 + 500
Ex: If I`m at 240kt and 86NP:
240 x 10 = 2400ft (This is the altitude to start decelerating to the VAPP.

45
Q

What is the Max Demonstrated Xwind for Take Off, and for Landing using Flaps 30 and 45?

A

Takeoff = 45kt Landing Flaps 30 = 38kt Landing Flaps 45 = 20kt

46
Q

For Go-around bleeds must be?

A

OFF

47
Q

Max slope allowed for ATR operations?

A

+/-2%

48
Q

What is the Dispatch Considerations for operation limitation with Landing Gear down the whole flight?

A

86%NP FL160 160KIAS

49
Q

Can the airplane be dispatched to operate with flaps up?

A

Yes, unless the airplane will encounter Ice on the route. However, it causes a huge loss in performance

50
Q

What is the PL angle where we can`t reduce more before feathering the bad engine in case of engine failure?

A

48 degrees on the PL

51
Q

Holding speed?

A

160Kts Clean
