6

Auto VNE

105 KIAS

7

Prohibited manoeuvres

Roll > 50 deg
Pitch up > 30 deg
Pitch down > 15 deg

8

Max IFR rate of climb or descent

1000 fpm

9

Max IFR approach slope

5 deg

10

Slope limits

10 deg on sides
4 deg nose up or down

11

Which switches need to be identified and confirmed prior to selection in flight?

Throttles
Fire handles
Hydraulic switches
Fuel panel switches
Governor switches

12

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

13

What is the obs gradient in a SID, unless otherwise advised?

3.3%

14

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.

15

What limits are used to determine OEI obstacle clearance performance?

2.5min power from TDP

N1 30mins limits = unlimited

Tq & ITT 30min limits = 30mins

16

The fuel interconnect switch should be selected open when..

Fuel quantity reduces to 600lbs.

17

What height and speed is the TDP standardised too?

45kts at 35 ft

18

What is Vtocs/Vtoss for the B412?

45kts

19

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

20

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

21

CR2 calculation of Critical point or equi-time point

23

NVG options if vis drops below 5000m

Revert to NVFR or IFR

Change direction

Land

24

NVG height vs speed requirements

<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 - 3x 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 FIRES brief

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)
