Q

what is the permitted temperature range for engine operation?

A

48
Q

what is the max positive load factor flaps up?

A

3.10g (G-SAYE 3.16g)

49
Q

what is the max positive load factor with flap?

50
Q

what is max crosswind for ground operation?

51
Q

what is max demonstrated crosswind for takeoff and landing?

A

30 knots (15 knots with 300lb of asymmetric load)

52
Q

what is max recommended tailwind for T/O and landing?

53
Q

when must external gust locks be installed?

A

windspeeds exceeding 30 knots

54
Q

what is the maximum runway slope?

55
Q

what is the maximum water equivalent depth for operation on contaminated runways?

56
Q

when do icing conditions exist?

A

OAT on ground and for takeoff is 5C or below and visible moisture is present

when operating on ramps/taxiways below 5C where surface snow/ice/slush/standing water may be ingested y engines or freeze on engines, nacelles or sensor probes

57
Q

what may lead to the build up of severe icing?

A

freezing rain, freezing drizzle, mixed icing conditions

58
Q

what must we do if we identify severe icing?

A

immediate request priority handling from ATC to facilitate a route or altitude change to exit icing conditions

59
Q

what bank angle must we not exceed while experiencing severe icing?

A

30 degrees

60
Q

how do we identify severe icing on the front or side windows?

A

granular dispersed ice crystals or translucent or opaque ice layers building up within a few minutes of exposure near the windshield frames

61
Q

how down identify severe icing on the propellor spinner?

A

translucent or opaque ice with granular dispersed surface roughness as opposed to typical ice accretion forming a cap or mushroom on the spinner tip

accumulation of ice on the propellor spinner farther aft than normally observed

62
Q

how do we identify severe icing on the lower wing surface?

A

accumulation of ice on the lower surface of the wing aft of the protected area

63
Q

what airspeed should we reduce to if ice accumulation rate should exceed the windshields ability to de-ice and visibility becomes limited?

64
Q

what flap position should we use if ice, slush, mud or structural damage is suspected on the horizontal stabiliser?

A

1 or up and increase Vref by 15knots

65
Q

what happens if there is an ice build up on the wings?

A

RSD and STALL warning indictions are unreliable- use Vref+15

66
Q

what is engine warm up time if oil temperature is below 55C?

A

4 minutes at taxi conditions

67
Q

when must the engine inlet anti-ice system be activated?

A

all ground and flight operations in visible moisture (including clouds and fog) while 5C or below

68
Q

how long can we use the engine inlet anti-ice for when icing conditions dont exist?

A

no more than 10 seconds

69
Q

when must the prop de icing system be activated?

A

all operations in actuator potential icing conditions

70
Q

when must prop mats not be switched on?

A

when the prop is stationary

71
Q

when MUST the surface inspection lights be operative?

72
Q

what must we do prior to checking the surface de-icing system on the ground if its above 40C OAT?

A

turn off the air conditioning

73
Q

what must be operating prior to operating the surface de-icing system below -10C in flight?

A

air conditioning/heating

74
Q

below what temperature can we not activate the de icing boots?

75
Q

what can we not select when the windshield de-icing is being used on the ground?

A

high temperature

76
Q

when can we not operate the windshield wiper?

A

above 140ias or on dry windshield

77
Q

on G-SAYE/ETAC/OAUR what is max EGT when using reverse thrust?

78
Q

on G-SAYE/ETAC/OAUR what is the max EGT when starting?

79
Q

what is the max altitude for an air start?

A

20,000ft if certificated altitude is above 15,000ft

80
Q

what is the minimum airspeed for an air start?

81
Q

what is the minimum oil temperature for air start?

82
Q

recite the permitted starter operation cycles?

A

first cycle: 60 seconds on 60 seconds off

second cycle: 60 seconds on 5 mins off

third cycle: 60 seconds on 1 hour off

83
Q

can we move the power levers below FI in flight?
