During flight planning for IFR or NVFR, what performance at the cruising alt is required for the B412?

A

1% climb gradient, which at 70kts Vy = 82ft/mins

For practicality - use 50ft/min.

Q

Outer marker check height procedure

A

Compare altimeter with published check height

If altimeter reads high - add difference to DA and adjust RADALT bug

If altimeter reads low - good to go. No adjustment req’d

Significant error - discontinue PA, switch to NPA

Q

NVG height vs speed requirements

A

<500’ = 80kts

< 200’ = 60kts

25
NVG recency requirements Flight time CCF HLS Winch
3hrs inc 3 take-offs, ccts and landings in last 6 months or NVG NPC in last 6 months NVG NPC annually HLS basic - 1x 6mths NVG winch - 1x 6mths
26
What equipment is required for NVIS flight?
a RADALT which - instant height - easy to read rate of change - audio and visual warnings of set height a pilot steerable search light (az + pitch) no IR filter below 500’ unless - can revert immediately or - 2 NVIS pilot operation aircraft has min equipment for NVFR or IFR each crew can access NVIS compatible torch each crew has lip light
27
Define HFIRES brief
H - Height low (check ht = Rgr, xxft radalt/ climb x 3/ ht good, hold) F - Fouling (free/ cut/ quick splice) I - Intercom (shout/ hand signals/ pax ICS) R - Runaway (Stby winch pwr OFF) E - Emergency ACO (cut cut cut) PLT ( minor - cont/ abort, major - brace or fly away) S - Stoppage (Stby pilot controls)
28
Overwater Ops requirements
Max use of FD. Alt hold on until base/final and visual with target area No extended transits blw 1000’ AGL. No descent blw 1000’ AGL until established in CcT area or over target. No descent blw 500’ AGL until surface visible and discernible, and no descending turns Altitude changes announced, radalt set, altitude callls every 100’ and every 20’ in last 100.
29
Max OAT temps
51.7 deg at sea level, less 2 deg/ 1000ft
30
Define final reserve
Fuel in tanks after final landing: - 20mins day VFR (range rate) ~ B412 = 250lb - 30mins Day/Ngt (holding rate) ~ B412 = 300lb Calculated at 1500’AGL at landing weight “MAYDAY, MAYDAY, MAYDAY FUEL” required if landing below FR. Also advise if your expecting to conduct a normal approach and landing and Emergency services are not req'd.
31
Define land as soon as practicable
Aircraft is airworthy and can continue to nearest airfield/ HLS where availability of tech assist is considered.
32
Define land as soon as possible
There is a clear threat to safety/ airworthiness if flight continues too long. Terminate flight at nearest safe approach and landing area. Tech assist not considered.
33
Define land immediately.
Significant risk if flight is continued, such as severe vibration or structural failure. Ditching, controlled descent into trees deemed a lesser risk.
34
When are survival suits to be worn?
Water blw 15deg, or Air blw 10deg (at sea level), or Combined Sea and Air temp 31deg or blw Or when desired due wind chill factor Take watch off and burp suit
35
VNE both cabin doors back?
100kts
36
How much effect will throttle manipulation have on yaw?
Up to 20deg

40
List the required fuels.
Taxi Trip Dest alt Holding Contigency Final reserve Additional Descretionary
41
Define taxi fuel
Taxi fuel allowance for all flights. 50lb
42
Define trip fuel...
Fuel needed from departure to destination. Includes, climb, cruise, descent, approach and landing. 750lb/hr
43
Define destination alternate fuel...
All fuel required from destination to alternate. Includes missed app, climb, cruise, descent, approach and landing fuel.
44
Define holding fuel...
Included if holding is required or expected. 600lb/hr
45
Define contingency fuel...
The greater of 10% of trip fuel or 5mins of holding above dest at 1500ft. Required by Babcock for all flights.
46
Define final fuel...
The useable fuel in tanks after landing. Day VFR 20mins =250lb NVFR/IFR 30mins = 300lb
47
Define descretionary fuel...
Any additional fuel carried by PIC.
48
Define additional fuel...
Fuel required to alternate aerodrome OEI. However as OEI fuel burn is less, not normally required as the 15mins at 1500ft requirement is covered by final reserve.
49
What happens to useable fuel when a boost pump fails?
We lose access to 61lbs of fuel.
50
Illumination of the FUEL TRANS light after 920lbs means what?
A check valve has failed and the fuel left over in the mid tank (use switch to find out) is unusable.
51
What happens when you pull a T handle?
Fuel valve - closes Part Sep door - closes Bleed air valve - closes (both engs) Fire extinguisher ccts - armed
52
What are some problems if the emergency load switch is used?
Engines in manual mode revert to auto Hyd system that was off, revets to on Both fuel boost pumps turn off
53
How do you calculate the required Rod for a 3 degree descent slope?
A - half the descent GS and add a zero B - descent GS x 5
