(No bug) Engine flames out at 18K AGL?

[HawkDCS]

Hey all I read the manual and it says to flip the fuel tank pressure to on when it it starts to cough and everytime I go through 18K it starts coughing I flip it over and engine never really relights? Low fuel pressure light comes on and its over lol.

 

I have tried the hand pump etc? I am climbing at 10-12 Boost and have even tried lower boost settings for fear of driving the motor to hard but I am lost how to get it above this altitude. :joystick:

 

I am climbing at 2850 RPM and around 10 boost.

I can't post pics atm as I'm on my phone but did you turn on the fuel pump switch (located front most of 3 toggles on the left of the seat)?

 

I ran into this issue middle of trying to record for a first flight video and ended up having to glide it back down. Found the switch as I can in to land with no engine and all the sudden my engine kicked in and I about crashed lmao

I had that too, but if you look at the table in the Manual, you'll see what you did wrong

 

From the manual:

 

Climbing

 

1. To achieve maximum rate of climb, pilots may make use of maximum power (Pk=12 ft/in2, n=2850 RPM). In extreme situations even combat mode may be used (Pk=18 ft/in2, n=3000 RPM), but for no longer than 5 minutes.

140 PRE-FLIGHT CHECKS

 

2. In all cases where maximum rate of climb is not required, climbing may be performed with a pressure 7ft/in2 and 2650RPM. Doing so conserves fuel and increases total flight range.

 

3. Refer to the following table for the most efficient speeds for climbing at certain altitudes: Altitude Speed From (ft) To (ft) mph

0 12000 185

12000 15000 180

15000 20000 170

20000 25000 160

25000 30000 150

30000 33000 140

33000 37000 130

37000 40000 120

40000 - 110

 

4. While climbing, ensure that the temperatures for coolant and oil do not exceed 125° and 90° C respectively.

 

5. Control of the radiator grates is automatic depending on the coolant temperature. The grates open at temperatures above 115°C. In case of system failure, the grates may be opened by pressing the button located on the left side of the pilot seat.

 

6. Supercharger 2nd speed engages automatically at 13500-14000 ft while climbing. While descending, the supercharger returns to 1st speed past 12500 ft.

 

7. If it is necessary to use 1st speed past 13500-14000 ft, set the dashboard switch to MS.

 

8. Fuel boost valve must be set to off. Switch on only in response to the red light signaling a loss of fuel pressure (lower than 10ft/in2)

 

9. Rules for using the fuel tanks: Startup, motor warmup, takeoff: Use main tanks. Switch fuel feed to use external tanks only at altitudes above 2000ft (600m) and only when external tanks are in place.

 

10. Before dropping external tanks that have not been fully exhausted, first connect the main fuel tanks, then release.

 

11. If the external tanks have no fuel remaining, or if it has been jettisoned, ensure that the valve for the external tanks is completely shut off. If they are not completely closed, the system will be fed air and may lead to interruptions in the motor operation.

 

12. Periodically check remaining fuel levels while in flight by pushing the fuel gauge button.

The gauge will begin to show remaining levels only after it begins feeding off the lower tank.

 

Also try again with lower boost, with like 8 or so, maybe even 7, as stated in number 2

It was the fuel pressure switch. Flipped her on and all good.

 

Thanks!
