DCS F-18 - Emergency of the Day 89 - S/W CONFIG Caution on DDI

S/W CONFIG

1. BIT/CONFIG page ... ... ... ... ... ... ... ... ... ... ... ... ... Identify lined out system.
2. Turn on affected system if not already on.

DCS F-18 - Emergency of the Day 90 - L or R STALL Caution on DDI

L STALL & / or R STALL

Audio = “Engine left, Engine left” or “Engine right, Engine right”

AOA = Angle of Attack
EGT = Engine Gas Temperature

* 1. Throttle affected engine ... ... ... ... ... ... ... ... ... ... ... ... IDLE

If stall does not clear -
- 2. Throttle affected engine ... ... ... ... ... ... ... ... ... ... ... ... OFF
- 3. Refer to Single Engine Approach ad Landing procedure.

If stall clears -
- 2. Check engine response at a safe altitude.
- 3. Land as soon as practical.

Cause

• Engine stall detected on designated side.

Remarks
Engine stalls result from conditions which exceed the stall margin of the engine (high AOA, steam or exhaust ingestion, etc.). Engine stalls are often indicated by an audible bang, airframe vibration, and visible flames out of the exhaust and / or inlet
Pop or surge stalls do not result in L or R STALL caution and usually self-recover. Multiple pop or surge stalls indicate the engine may not self-recover and are usually the result of engine or aircraft damage.
Hing stalls result in a L or R STALL caution and are indicated by a lack of throttle response, increasing EGT, and steady or decreasing rpm. If engine rpm continues to fall, the L or R FLAMEOUT caution may also be set.

CAUTION
Do not operate the windshield anti-ice / rain removal system on a dry windshield. If a WDSHLD HOT caution appears, place the WINDSHEILD switch to OFF immediately to prevent heat damage to the windshileld.

16.6 LANDING GEAR UNSAFE / FAILS TO EXTEND

These check lists are a nightmare, very poorly written and I intend to rewrite them in a more logical way. In the mean time here is the checklist typed out as per the manual.

If the LEFT or RIGHT landing gear position indicator is flashing, and the landing gear warning light and warning toine are on, refer to PLANING LINK FAILURE.

If the landing gear warning light and warning tone are out -
1. AOA indexer lights ... ... ... ... ... ... ... CONFIRM ON
2. INTR LT MODE switch ... ... .... ... ... CHECK DAY
3. LT TEST switch ... ... ... ... ... ... ... ... TEST

If bulb(s) test bad and AOA indexer lights on -
5. It is safe to assume the landing gear is down and locked.
6. Get a visual inspection (if practical)

• The approach lights should be illuminated of the landing gear is down and locked.

7. Landing gear may be raised as necessary to consere fuel.
8. Make a normal approach.

If the landing gear warning light and warning tone are on -
1. AOA indexer lights ... ... ... ... ... ... ... CONFIRM OUT
2. LT TEST switch ... ... ... ... ... ... ... ... TEST

• Verify that all 3 position lights and the landing gear warning light are on..

3. LDG GEAR handle .. ... ... ... ... ... ... CHECK FULL DN (DO NOT CYCLE)
4. LG circuit breaker ... ... ... ... ... ... ... CHECK IN (RIght Shoulder)

5. Get a visual inspection (if practical)

• If one or more landing gear indicates unsafe, a visual inspection can only confirm general position and obvious damage.
• There is no external indication of a locked landing gear.

Perform the following in order until 3 down and locked -
6. LG circuit breaker ... ... ... ... ... ... ... CYCLE (RIght Shoulder)
7. Perform Landing Gear Emergency Extension procedure.
8. Perform positive and negative g manoeuvres and gently roll and yaw aircraft to obtain safe gear indication.

If HYD 2A is operative and any gear still unsafe -
9. LDG GEAR handle ... ... ... ... ... ... ... PUSH IN then ROTATE 90 Deg CCW
10. LDG GEAR handle . ... ... ... ... ... ... UP (DOWNLOCK ORIDE if required)
11. If all gear up and locked, consider selective jettison of unwanted stores.

• Selective jettison can only be performed with LDG GEAR handle UP and all landing gear up and locked.

12. LDG GEAR handle . ... ... ... ... ... ... DN
13. Perform Landing Gear Emergency Extension Procedure.
14. Perform positive and negative g manoeuvres and gently roll and yaw aircraft to obtain safe gear indication.

If any gear still indicates unsafe -
15. Refere to Landing Gear Malfunction ... Landing Guide Chart

If at any time landing gear indicates three down andn locked -
16. LDG GEAR handle . ... ... ... ... ... ... DO NOT CYCLE
17. Make minimum sink rate short field arrested landing (if available).
18. Pin the landing gear after landing.

16.5 PLANING LINK FAILURE

A planing link failure is indicated by a gear handle light, continuous rate beeping tone, and a flashing LEFT or RIGHT advisory light with athe gear handle down. With no braking or landing rollout, a planing link failure will normally cause the aircraft to drift into the failed gear as teh aircraft decelerates. However, the failure can result in landing gear positions that can. Range from slightly angled to fully perpendicular to the aircraft. The resulting swerve in the direction of the failure can be severe. Planing link failure indications that are momentary or disappear after initial activation may be indicative of an actual planing link failure.

WARNING

• A planing link failure may cause a sudden swerve on touchdown in the direction of the failed gear.
• Planing link failure may not be Annunciator until after touchdown and may provide little to no pilot reaction tine between initial annunciation and a violent yaw/swerve. Therefore, if flyaway airspeed is available, pilots should be prepared to make the decision to execute a go around immediately at initial planing link failure annunciation.

CAUTION

• Planing link failure indications that are momentary or disappear after initial activation may be indicative of an actual planing link failure.

If detected after touchdown and flyaway airspeed available -
* 1. Go around.

If Flyaway airspeed not available -
* 1. Select emergency brakes (if appropriate).
* 2. HOOK handle ... ... ... ... ... ... ... .. ... ... DOWN (if required).

If detected airborne, or following go around -
1. LDG GEAR handle ... ... ... ... ... ... ... ... ... DO NOT CYCLE
2. ANTI SKID switch . ... ... ... ... ... ... ... ... ... OFF

If arresting gear available -
3. Make a fly-in short field arrestment with LSO assistance (if available).

If assrestijng gear not available -
3. Make a minimum sink rate landing.
4. Consider touchdown on good gear sir of runway.
5. Avoid braking until as slow as practical or until needed to prevent loss of directional control.
6. Brake using the good gear ad maintain directional conttrol with NWS.
7. Use symmetrical braking only if necessary to avoid departing the runway.

WARNING

• Use of symmetrical shell brakes with a planing link failure may cause a sudden in the direction of the failed gear.
• The ability to maintain directional control.
• Lateral asymmetry via heavier or larger stores on the side of the failed gear may aggregate the severity of the yaw/swerve in the direction of the failed gear.

8. Do not taxi once stopped.

16.8 HOOK FAILS TO EXTEND

If hook will not extend -
1. Hook circuit breaker ... ... ... .... ... ... ... ... PULL

If hook still will not extend -
2. Divert.

If arrest landing required -
2. Shut down right engine, restart for landing.

Note
Shutting down right engine to reduce HYD 2 backpressure may allow partial arresting hook extension. Restart engine for landing. Arresting hook may retract at a maximum of 2”/minute.

[VBF-12 Gosling]

16.10 AUTO FLAP LANDING

1. Do not exceed 10 Deg AOA.
2. Do not slow below 154 knots.
