DCS F-18 - Emergency of the Day 74 - NAV HVEL Caution on DDI

NAV HVEL

INS = Inertial Navigation System
GPS = Global Positioning System
ADC = Air Data Computer
NAVCK = Navigation Check option on DDI

1. Crosscheck velocity vector.
2. Crosscheck horizontal velocities on HSI / DATA / NAVCK sublevel.

Cause
GPS not operating -

• INS and ADC velocities disagree.
• Can be caused by high wind velocity.

GPS operating -

• INS and GPS, ADC and GPS, or INS and ADC horizontal velocities do not agree.

DCS F-18 - Emergency of the Day 77 - OBOGS DEGD Caution on DDI

OBOGS DEGD

OBOGS = On Board Oxygen Generation System
OXY = Oxygen
BIT = Built In Test
DEGD = Degrade

GROUND
1. Check oxygen system integrity:

• Mask integrity
• Hose connections
• OBOGS monitor pneumatic BIT plunger unlocked and fully extended.

IN FLIGHT
* 1. Emergency oxygen green ring(s) ... ... ... ... ... ... ... ... PULL
* 2. OXY FLOW knob(s) ... ... ... ... ... ... ... ... ... ... ... ... OFF
* 3. Initiate rapid descent to below 10,000 feet cabin altitude.
- 4. Check oxygen system integrity:

• Mask integrity
• Hose connections
• OBOGS monitor pneumatic BIT plunger unlocked and fully extended.

If system integrity not comprised -
- 5. Maintain cabin altitude below 10,000 feet.
- 6. OBOGS control switch ... ... ... ... ... ... ... ... ... ... ... ... OFF

Once below 10,00 feet cabin altitude and hypoxia symptoms present -
- 7. Consider removing mask or resetting emergency oxygen system or esuming normal OBOGS operation if flow appears normal and donning of mask is desired.
- 8. Land as soon as practical.

If system integrity restored -
- 5. Resume normal OBOGS operation.
- 6. Reset emergency oxygen system.

Quick Memory:
PULL / OFF / Descend

Cause

• Oxygen concentration is below acceptable limits.
• Disconnected oxygen hose.
• Removing oxygen mask without placing the OXY FLOW knob to OFF.
• System gas leak (broken integrity).

WARNING

• Good flow does not equate to good oxygen concentration. An OBOGDS DEGD caution. Indicates that the oxygen concentration is inadequate and hypoxia may result
• Under less than optimum conditions (low altitude, heavy breathing, loose-fitting mask, etc.), as few as 3 minutes of emergency oxygen may be available.

OCS

OCS - Overlay Controlled Stores
MC = Mission Computer
SMS - Stores Management System

1. Attempt to reload overlay.

Cause

• MC or SMS overlay halted due to run time.

Remarks
Stores that require overlay may not be available.
