Q

How is the Center of Gravity measured? What are the considerations?

A

The limits of the center of gravity are given in percentage of the mean aerodynamic chord (MAC), taking into consideration the landing gear extended.

Q

VMCL Speed? “Lower speed in Landing Config”

Study These Flashcards
A

Flaps 15 = 91 KIAS Flaps 30 = 89 KIAS

25
Takeoff and Landing Tail Wind limitation?
10/15 KT
26
Maximum Cross-wind in takeoff and landing?
Takeoff 45kt Landing 38kt
27
Refueling Max Pressure in PSI?
50 PSI
28
Max Fuel Imbalance on both tanks?
1212 Lbs
29
Minimum Height for AP engagement?
100ft
30
Minimum Height for using AP and YD except for Takeoff, Go-around and Approach?
1000ft
31
VS and IAS use Altitude Limitation during approach?
160ft
32
CAT 1 Approach mode Altitude Limitation during approach?
160ft
33
Which engine on the ATR42-320 is the critical engine?
Left Engine
34
What is the VMCG and VMCA?
It's not a fixed speed. Must be calculated
35
What is VMCL? What is the procedure? What is the speed for Flaps 15 and 30?
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
What is the VMLB Minimum Maneuvering Speed Low Bank? What is the bug colour on the ASI?
Limited Bank Angle of 15° for a certain speed according to the current aircraft weight. This one is set on the White Bug
37
What is VGA speed?
Minimum speed to perform maneuvering during a go-around maneuvering VGA = VmHB + 5kt or 1.1 x VMCA whichever is higher
38
What is the Vapp?
Final Approach speed in landing configuration + Winds correction speed
39
What is Vref?
Referencia Landing Speed Consider Landing Configuration, Gear Down + Flaps 30° at Final Approach.
40
What is the appropriate NP Propeller setting during the Climb phase?
Set 86.3NP initially. When TQR reduces below 75%, set 77.3NP
41
About Max Torque calculation, which phases are mandatory to calculate max torque?
Takeoff and Go-around. The other phases we just calculate to cross-check if FDAU is working properly.
42
Which are the temperatures considered Atmospheric Icing Conditions?
On Ground = OAT +5 or below with visible moisture In-flight = TAT +7 or below with visible moisture
43
Which are the temperatures and conditions considered Ground Icing Conditions?
OAT +5 or below with Standing water, Snow, Rain, or Slush when operating on TWY, RWY, or Ramp.
44
What is Decelerating Height? How is the calculation?
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
What is the Max Demonstrated Xwind for Take Off, and for Landing using Flaps 30 and 45?
Takeoff = 45kt Landing Flaps 30 = 38kt Landing Flaps 45 = 20kt
46
For Go-around bleeds must be?
OFF
47
Max slope allowed for ATR operations?
+/-2%
48
What is the Dispatch Considerations for operation limitation with Landing Gear down the whole flight?
86%NP FL160 160KIAS
49
Can the airplane be dispatched to operate with flaps up?
Yes, unless the airplane will encounter Ice on the route. However, it causes a huge loss in performance
50
What is the PL angle where we can`t reduce more before feathering the bad engine in case of engine failure?
48 degrees on the PL
51
Holding speed?
160Kts Clean
