Question 1

State how to calculate Bingo Fuel.

Answer 1

FoG
\+
Recovery Fuel (e.g. a cct, or IRM/ CFFR...)
\+
Fuel to negotiate airspace
\+
1kg per kt of headwind to base
\+
1kg per kt of headwind from base to Div
\+
2 x Range to home plate
\+
20kg if within 150nm of home plate.

Question 2

State how to carry out a Bingo profile.

Answer 2

Climb using full power and 350kts to FL(2 x range to home plate)

At ToC, set power for 300kts (gives ~580 degrees T6) or M0.7 above 30,000ft.

Confirm the airfield recovery state.

Check the INAV datablock for estimated arrival fuel.
If this is uncomfortably close, calculate the fuel required for descent (will use [FL/10]kg of fuel) and the fuel required to reach ToD (using EMP fuel flow).
If this is still uncomfortably close, use the FRC figures for DI2.5.

Start range descent at ([FL/10] x 1.5)nm from base.

Question 3

How many kg of fuel will you burn per minute at low level?

How far will 100kg of fuel get you at LL?

How far will 105kg of fuel get you at LL?

Answer 3

24kg per minute.

28nm

30nm

Question 4

What should you do if you make your fuel calculations at the top of the bingo profile and you don’t have the fuel to get back to base above FoG?

Answer 4

Consider diverting if there is a suitable airfield closer than base.
Or
Declare a pan for fuel.

Question 5

On a typical nav route, what should your Joker fuels correspond to?

Answer 5

J1: Fuel required at LLEP to complete planned route.

J2 + J3: Fuel required off targets 1 and 2 to complete planned route.

Question 6

State the equation for combat fuel.

Answer 6

Combat fuel = Current fuel - fuel required to complete planned route.

Question 7

When does the bingo warner activate?

Answer 7

Once fuel has fallen below the set level for over 30s.

Question 8

How long should you plan your IP-Tgt runs to be?

How fast should you plan to fly them?

Answer 8

1 minute.

450kts groundspeed.

Question 9

At what height should you plan the ML transit to the LLEP?

Answer 9

At FL[2 x range to LLEP]

Question 10

At what range from the LLEP should you start your descent for a:

Range Descent

Tactical Descent

Answer 10

Range: At [(FL/10) x 1.5]nm

Tactical: [(FL/10) x 0.5]nm

In reality, put the vv on the point you want to enter LL and use the throttle to make it work.

Question 11

What speed should you plan to transit ML at:

Above 10,000ft.

Below 10,000ft.

Answer 11

Above 10,000ft: M0.7

Below: 10,000ft: 420kts groundspeed.

Question 12

What speed range can you use to correct timings during the ML transit?

Answer 12

0.6M to 0.8M.

Question 13

How far can the IN system drift when operating in IN-only mode?

Answer 13

Up to 0.8nm per hour.
