Fuel Burn rates:

Cruise/Climb/Descent:
Holding:
OEI:

Answer 3

Cruise: 360kg/hr
Holding: 300kg/hr
OEI: 250kg/hr

Question 4

Final reserve fuel day and night unaided:

Answer 4

Day = 20 mins (120kgs)
Night = 30 mins (180kgs)

Question 5

How many routes can be stored in the tiger nav system?

Answer 5

5

Question 6

How can fuel flow be calculated in the aircraft?

Answer 6

When in a stable flight regime:
Total fuel / endurance + 20 (in minutes)

Question 7

What are the considerations for each step within the FCLEARM checks?

Answer 7

Fuel = Calc fuel flow, ferry tanks
Comp = DMGT next WP
Log = Flightlog page
Engine = Check MFD pages
Altimeters = QNH/DH
Radio = Freqs
Mission = MEP

Question 8

DIAFARE

Answer 8

Divert = Direction/distance
Information = ATIS as req
Altitude/airspace = Weast/avoid CTRs
Fuel = Gain vs lose fuel?
AVRM = Risks
Radios = R/T for updated SAR/Tracking
Execute = TATS/TTF/TOPO

Question 9

How often should FCLEAM checks be completed?

Answer 9

Top of climb
30 min intervals
Passing the safe return point

Question 10

What is the lost procedure?

Answer 10

C - I think we’re lost…
A - Safe height/heading
N - Orbit in place or continue?
C - Ask ATC/other aircraft
A - Admin as req

Question 11

CEFG

Answer 11

Compasses
Engine
Fuel
GPS

Question 12

Explain how the aircraft calculated BINGO, M.BINGO and JOKER?

Answer 12

BINGO = Presented when the selected NAV route cannot be completed above min fuels at the current fuel burn/GS combination
M.BINGO = When the INTERNAL fuel level if that of the manual bingo
JOKER = When the internal AND external fuel is that of the manual joker

Question 13

Where and how can ferry tank fuel be added?

Answer 13

On the MM page, top right, added separately to delta mass

Make sure you are in KG/L as req

Question 14

Ferry tanks can either be critical or non critical to completing a flight, explain how checks should be completed with each situation?

Answer 14

No critical = Simple flow check —> Ferry tank in auto mode
Critical = Ferry tank XFER Cx —> Single continuous XFER

Question 15

Explain the simple flow Cx of the ferry tank?

Answer 15

• Turn the ferry tank XFER switch to ON
• Confirm that the internal fuel level is increasing

Question 16

Explain the difference between feasibility, mission and check calc on the CDU:

Answer 16

Feasibility Calc:
Mission Calc:
Check Calc: Used to calc fuel for direct to/WPs seperate to the nav route

Question 17

At what point does the F.LOW caption come on?

Answer 17

When both tanks are below 450kgs

Question 18

What is the capacity of the ferry tanks?

Answer 18

292kgs

Question 19

What are the three different ways to update your loc when GPS has failed?

Answer 19

FIX = Use a known WP to re-centre the aircraft
LOS = Uses where the RMS is looking
Euro grid = Update POS via tac map cursor

Question 20

Explain what green, blue, yellow and red mean on the Eurovision elevation map?

Answer 20

Red = At/below your height
Yellow = Below DH
Green = Above DH, below DA
Blue = Above DA

Question 21

Explain how speed corrections are made during low level nav:

Answer 21

Increase/decrease speed by how early/late you are for 90 sec

E.g. 20 sec early, slow down to 100kts G/S for 90 sec

Note: If timing corrections are too significant, make half the speed correction and double the time

Question 22

HASEL Cx:

Answer 22

Height: Planned leg height, not below and DH set
Area/auth: Area is suitable and auth we have
Security: Set front/rear
Engine: ACFT Systems green
Lookout: Clear below

Question 23

At 120, 100 and 75 ground speed what can be used to calculate distance to a WP?

Answer 23

120kts = 15 sec/km = 4km/min
100kts = 20 sec/km = 3km/min
75kts = 25sec/km = 2.2km/min

Question 24

At what angle of bank does the tip path plane reach below the LDG gear and what can pilots use to remind them?

Answer 24

36ºAoB, if you have to look through the roof during a turn, the blades are below the wheels

Question 25

Which Cx must be completed before descending LL?

Answer 25

FENCE Cx

Question 26

Which Cx must be completed before descending LL?

Answer 26

FENCE Cx

Question 27

You are LL, authed NB 50AGL, is it acceptable to have the DH sound when “cresting”?

Answer 27

Not really, the auth is 50ft, not “50ft unless there’s a ridge line then pay it off” (Advice from Gene Walker*)

Question 28

When operating away from OK, what additional radio information is required?

Answer 28

POB is often missed

Question 29

Explain how the NAV —> Guidance page can be used during a TOT navigation?

Answer 29

Guidance displays the TOT to the nearest whole minute at the final WP, it is useful if wanting to arrive at a whole minute to have the number flashing between the two.

E.g. Arrival time 00:10Z, you want to see 09/10 flashing as this mean the computer puts you somewhere between 9:30sec and 10:30sec

Question 30

How can you listen to more than 3 radio freqs at a time?

Answer 30

Marker beacon can dial up 126.7
