PSA: Remove your intake covers before engine start and cold-crank start procedure.

[J20Stronk]

Remember to have the crew chief remove the inlet covers an ladder (F8 radio menu), otherwise you will end up like that British F-35 in the Mediterranean Sea.

 

Jokes aside, the startup sequence is still the same if it's the first start of the mission. But if you shutdown the engine and need to start it up again (after refuel, repair, etc.), you need to start with a cold crank instead of the JFS.

 

To do a cold-crank start:

 

1. Starter Pump, Eng Control > On

Throttle > Uncaged and Idle

 

2. Engine Start switch > Aft (ENG)

 

3. Push and hold the Ground Start button for ~5 sec. Ensure START lights up on the upper right Advisory Panel. RPM will climb to ~20% without JFS.

 

4. Once RPM is steady 20%-21% wait for RPM to drop back to 0%. Then, Engine Start switch > Center (START)

 

5. Hold Ground Start for another 5 sec until RPM and T4 begin climbing. Monitor RPM and T4 until nominal.

 

Again, cold-crank starts should only be done if you shut down the engine and need it back up and running shortly after. Just use normal starts in most cases.

Appreciate this, thank you.
