Max aircraft gross weight
Min aircraft gross weight
Min IFR airspeed
Airspeed vs mast tq limit

Roll > 50 deg
Pitch up > 30 deg
Pitch down > 15 deg
Max IFR rate of climb or descent
Max IFR approach slope
10 deg on sides

Which switches need to be identified and confirmed prior to selection in flight?
Fuel panel switches
The max wind speed for B412 starts and stops is
45 kts steady or
35 kts steady with 10 kt gusts
Ads variation - gust spread of 10 or more exceeding 35kts
What is the obs gradient in a SID, unless otherwise advised?
During flight planning for IFR or NVFR, what performance at the cruising alt is required for the B412?
1% climb gradient, which at 70kts Vy = 82ft/min.
For practicality - use 100ft/min.
What limits are used to determine OEI obstacle clearance performance?
2.5min power from TDP
N1 30mins limits = unlimited
Tq & ITT 30min limits = 30mins
The fuel interconnect switch should be selected open when..
Fuel quantity reduces to 600lbs.
What height and speed is the TDP standardised too?
45kts at 35 ft
What is Vtocs/Vtoss for the B412?
What timing compensation method for wind can be applied during a holding pattern?
Headwind - increase outbound timing by 2 secs for every knot of head wind
Tailwind - take 2 sec/per kt off outbound leg
Outer marker check height procedure
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
CR2 calculation of Critical point or equi-time point
Total dist. Dist to cp
G/S on + G/S home
CR2 Calculation of PNR
Time to PNR. G/S Home
Endurance (mins). G/S out +
Minus FR and Variable. G/S home
NVG options if vis drops below 5000m
Revert to NVFR or IFR
NVG height vs speed requirements
<500’ = 80kts
< 200’ = 60kts
NVG recency requirements
3hrs inc 3 take-offs, ccts and landings in last 6 months or NVG NPC in last 6 months
NVG NPC annually
HLS basic - 3x 6mths
NVG winch - 1x 6mths
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
