The max wind speed for B412 starts and stops is
45 kts mean wind speed in steady wind conditions
35 kts mean wind in gusty wind conditions
(momentary gusts in excess of 45 kts are acceptable)

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/mins
For practicality - use 50ft/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?
45kts
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
