DCS F-18 - Emergency of the Day 15 - ASPJ Cautions on DDI

The Airborne Self Protection Jammer (ASPJ) has a number of cautions associated with it. Most are for “Information” and no risk to flight. There is only one action. So, this post will deal with them all in one go.

ASPJ AMP

ASPJ DEGD

ASPJ HI B

ASPJ LO B

ASPJ OVRHT & ASPJ OH Left WCA Panel

ASPJ RPTF

All for “Information” except:

ASPJ DEGD

1. Run ASPJ IBIT.

Causes

• ASPJ AMP = BIT detected failure of Receiver RF -preamplifier.
• ASPJ DEGD = Continuous BIT failure detected.
• ASPJ HI B = BIT detected failure in ASPJ HI-Band
• ASPJ LO B = BIT detected failure in ASPJ LO-Band
• ASPJ OVRHT = Non safety-of-flight overheat in ASPJ.
• ASPJ HI B = BIT detected failure in ASPJ RF tuneable filter.

- 17. Land as soon as practical.

Quick Memory
MIN / PULL / OFF / DESCEND

Causes

• Designated air turbine starter rpm too high (e.g., both sources of ATS overspeed cutout protection have failed).(
• ECS valve failures are routing engine bleed air to rotate the corresponding ATS.

Remarks

WARNING

• Under less than optimal conditions (low altitude, heavy breathing, loose fitting mask, etc.), as few as 3 minutes of emergency oxygen may be available.
• If both bleeds secured -
• No OBOGS
• No ECS or cabin pressurisation
• No anti-g protection
• No external fuel transfer
• No crossbleed start
• No throttle boost
• No windshield anti-ice / rain removal
• May get AV AIR HOT during approach
• To prevent canopy fogging, select OFF / RAM or RAM / DUMP and move the DE-FOG handle to HIGH

CAUTION
Regardless of the engine start air sourceutilised, the corresponding GEN switch should be ON, as the generator provides primary overspeed cutout protection for the ATS.

- 15. Maintain altitude below 10,000 feet MSL prior to emergency oxygen depletion (10 to 20 minutes)
- 16. Consider removing mask and resetting emergency oxygen system once below 10,000 feet MSL

If AV AIR HOT caution appears -
- 17. Non-essential Avionic equipment ... ... OFF (eg RADAR, UFC controller avionics, ECM, Sensors,
- 18. Land as soon as practical.

IN FLIGHT - SINGLE
1. BLEED AIR knob ... ... ... ... ... ... ... ... OFF (DO NOT CYCLE)
2. Land as soon as practical.

Causes

• The corresponding primary bleed air shutoff valve has been commanded closed.
• BALD system detected a leak in one or both bleed air systems and the overheat condition no longer exists (L, R, or both cautions).
• Over pressurisation detected in one or both systems (both cautions)
• BLEED AIR knob in L OFF, R OFF, or OFF (L, R, or both cautions).
• ENG CRANK switch in L or R (L or R caution, respectively.)
• FIRE test switch in TEST A or TEST B (both cautions).
  

[/ol][/ul]
BLD OFF cautions are not an indication of actual valve position. Valve(s) could still be open allowing bleed air to leak.

Bleed air leak MSP code: 831
Over pressurisation MSP code: 833
MSP = Maintenance Status Page. Part of the Integrated Fuel / Engine Indicator (IFEI).

WARNING

• Automatic functioning of the BALD system may extinguish the red BLEED warning light(s) prior to aircrew recognition and may not trigger the appropriate voice alerts or the voice alerts may be the only indication of a bleed air system leak. In this case, cycling the BLEED AIR knob to remove the BLD OFF caution(s) reintroduces hot bleed air to the leaking duct. If the sensing element was damaged by the leak, automatic shutdown and isolation capability may be lost. Extensive damage or fire may result.
• Under less than optimal conditions (low altitude, heavy breathing, loose fitting mask, etc.), as few as 3 minutes of emergency oxygen may be available.
• If both bleeds secured -
• No OBOGS
• No ECS or cabin pressurisation
• No anti-g protection
• No external fuel transfer
• No crossbleed start
• No throttle boost
• No windshield anti-ice / rain removal
• May get AV AIR HOT during approach
• To prevent canopy fogging, select OFF / RAM or RAM / DUMP and move the DEFOG handle to HIGH

DCS F-18 - Emergency of the Day 24 - L or R BOOST LO Caution on DDI

L BOOST LO &/or R BOOST LO

1. Limit corresponding afterburner usage above 30,000 Feet.
2. Check for indications of fuselage fuel leak.
3. Monitor fuel transfer.
4. Land as soon as practical.

Causes

• Loss of fuel pressure to designated engine.
• May indicate fuselage fuel leak.
• May indicate fuel transfer failure.
• If assocaiate with GEN, and both HYD circuit cautions, may be a PTS failure.
• May result from prolonged transitions through zero g (greater than 2 seconds).

Afterburner may not operate above 30,000 feet. The crossfeed valves open automatically

PTS = Power Transmission to hold him as much as Posib

DCS F-18 - Emergency of the Day 25 - BRK ACCUM Caution on DDI

BRK ACCUM

1. Extend landing gear as soon as possible.

Cause

• Emergency brakes may not be available.

CAUTION
A BRK ACCUM caution in flight is not normal and may indicate a possible leak in teh isolated HYD 2B system. If the caution appears in flight, do not attempt to recharge the accumulator as this may result in additional loss of HYD 2B fluid.
