3.7.10 Fuel leak
Battle damage may cause fuel leaks. Fuel leaks may be noticed visually with a sudden drop of fuel
quantity at the time of battle damage and an abnormally fast needle movement (towards empty).
Fuel leak may induce fuel imbalance obviously. Afterburner use should be avoided.
As soon as a fuel leak is suspected the range should be maximised and a climb to higher altitude
made to maximise the glide range. SFO should be planned for landing.
Fuel leak may be minimised by identifying the source of the leak and bypassing automatic forward fuel
transfer by placing the FUEL QTY SEL knob out of the NORM position.
ENG FEED may be placed accordingly depending on the source of the leak to counter the imbalance.
In any case, a fuel leak is a critical in-flight emergency and landing should be planned ASAP.
3.7.11 Oil Leak
Battle damage may lead to oil loss and the engine cannot work without oil. An oil leak may be noticed
on the OIL pressure gauge. Oil pressure is dependent on throttle setting and must be minimum 30 psi
at flight idle for the PW engine and minimum 25 psi at flight idle for the GE engine F-16. Any pressure
below these limits should be considered as an in-flight emergency and landing should be considered
as soon as possible.
Please note the HYD OIL PRESS warning light may not illuminate immediately. Oil pressure issues
are usually slow to develop.
Whenever suspecting an OIL pressure loss minimise throttle movement (place throttle around 80%
and try to leave it there unless absolutely required), minimise manoeuvring and plan for a SFO
approach at the earliest convenience.
You may activate the EPU and monitor hydrazine consumption. If you leave the EPU OFF, be ready to
turn it ON as soon as the engine seizes.
3.7.12 Battle Damage Checks
4.34 seriously increased the possibility of system failures due to battle damage. Engine stalls, fuel
leaks and oil leaks are a real possibility and further emphasise the need for battle damage checks.
It is therefore advised to request a battle damage check from one of your human wingmen (if
available) to visually check the extent of the damage.
Fuel leaks and oil leaks may be visible from your wingman
’s perspective. Both create white smoke,
but oil leaks always originate from the engine while fuel leaks may originate from either tanks (wing,
fuselage, etc.)
