737 Audio Warning Explained (FSX)

This brief video will give a rundown of the Boeing 737 Series aircraft audio warning systems. Most Flight Simulator addons do not allow you to test these systems, however, the iFly 737 NG does. Most addon aircraft will have the following alerts. These tests should be part of your flight line at some point during the day. I choose to test them before every flight, but they should be tested at least on the first flight of the day to check that the systems are working.

We will be demonstrating the following systems:

-Ground Proximity Warning Systems (GPWS)-
This system is meant to warn the crew of approaching terrain, excessive descent rates, and in worst case scenarios, impending crash. It is most easily recognized by the "WHOOP WHOOP PULL UP" sound. Should alerts become present in the cockpit, take note of the surrounding terrain, and your current flight conditions, and make decisions based on the situation to avoid crashing.

-Fire Warning System (a.k.a. Fire Bell)-
The Fire Bell is an alarm that goes off and sets of large FIRE WARN lights in the cockpit to alert the crew of a fire or overheat on the aircraft's crucial areas, such as engines, the Axillary Power Generator (APU), wheel well, and cargo areas. It is easily recognized by the old-phone-like bell. In the event of a fire before V1 (decision speed on takeoff) you should abort the takeoff and turn the aircraft down wind to avoid the fire and smoke from blowing back on the aircraft. If it is an engine fire, immediately set the fuel cutoff lever to cutoff for the engine in question, then pull out and twist the large red level under the fuel cutoff lever marked with 1 or 2 and turn on APU. (Select the one for the corresponding engine - engine one fire, pull the red 1 lever). This will set off a fire extinguishing fluid that will (hopefully) extinguish the fire and allow you to safely land. If an APU fire occurs, turn off APU and pull and twist the APU fire extinguisher lever.

-Stall (Stick Shaker)-
the alert that the aircraft is no longer achieving enough lift to fly. Should a stall occur, you should apply full power on the throttles and lower the aircraft's nose to regain airspeed. If the stall is caused by icing, apply your de-ice immediately and follow the same procedure until the aircraft returns to normal flight. The system (though only a sound in FSX) is quite literally the sound of the yoke shaking, as this is the notification to the pilot to take corrective action.

-Overspeed (Clacker)-
The overspeed alarm notifies crew members that the aicraft is traveling faster than is safe for it. The fix is easy, reduce speed! This can be done by increasing climb (if climbing) or decreasing descent (if descending), and the speedbrake can be used if A: the aircraft's speed cannot be reduced in timely manner without it (withing 15 seconds is the time range I use), B: the descent MUST be made as it is and reducing your descent rate is not an option.

-Traffic Collision Avoidance System (TCAS)-
The infamous TCAS voice offers audio alerts to the crew members of nearby traffic that is considered a threat to safety. There will be warnings such as "TRAFFIC TRAFFIC" which only indicates a potential traffic conflict. Announcements following it such as "DESCEND DESCEND" indicate the correct action to be taken. Follow the instructions of the TCAS system and your visual references (if any exist) to avoid collision.

*Note - this tips are verified by following these procedures in the real aircraft and input from real pilots, however, this information is intended for Simulation purposes only. DO NOT USE FOR REAL AIRCRAFT TRAINING.

Nice video man! I liked it

[TFDiFlight]

@bkingair350 I'm glad! Stay tuned for a cool video tonight!

[Instucablanator]

@TFDiFlight you sound pretty young, amazing you have learned all this stuff ! keep the vids comin :)

[eclipse245]

@Pvjinflight I wish I did. But I didn't It came on as soon as I reached cruise. 290 kts, flaps up, gear up, no parking break.

It shouldn't be sounding at cruise lol.

[Pvjinflight]

@ThePGOmega At least this doesnt crash my sim with Fspassengers addon like PMDG 747 seems to do...

[Pvjinflight]

@eclipse245 More like you have configured it wrong

[eclipse245]

I got the takeoff config warning, once I reached cruise altitude....buggy fs aircraft -.-

[wildfiremichael]

Hey which program do you use to move around in the vc??

[diegodaudt]

@codboroks97 Because MS is too cheap to finish them.

[TheDiego1255]

wat addon is this?

[codboroks97]

why do default airplanes not have as many controls than the add on aircraft?

it really take half of the fun out of the game

[ThePGOmega]

Lol this looks like a cartoon compared to the PMDG NGX ;) Incidentally, the GPWS test button needs to be held for 10s in the real plane in order to initiate the full test
