Cabin altitude warning or rapid depressurisation
3 step procedure.
Emer descent starts from step 2.
(ie you may do a non cabin alt emer descent with masks off.)
PF decides and calls:
‘Cabin Altitude Warning - don masks regulators 100%’
estab comms. ‘Capt on 100% O2, cancel horn’
Note: a cabin altitude warning above 10,000’ is always the result of a cabin altitude exceedance (except in the very unlikely case of an air-ground logic system failure). The IDENTIFY & CONFIRM process may be omitted.
Checklist is also called cabin altitude warning…imho that covers you.

Aborted Engine Start.
PROCEDURE
Reasons to abort?
Limitations
ESL cutoff
Non memory has you motor engine in GND for 60s, if ESS already in auto wait till N2 blw 20% and switch to GND for 60s.
Abort for:
* N1 or N2 doesn’t inc or inc v slowly after the EGT increases
* no oil pressure indication by the time that the engine is stable at idle
EGT does not increase by 15 seconds after the engine start lever is moved to IDLE detent
the EGT quickly nears or exceeds the start limit.
hot,hung,wet,oil.
2min starter duty time with 10s off between.
stable at idle is when EGT start limit redline not shown.
Remember after 3 aborted starts you require 15 min cooling.
Engine limit or surge or stall
May lead to engine shutdown.
Below the line you have:
- Engine indications are abnormal or EGT continues to increase then:
- Eng start lever..confirm..cutoff
Consider APU, descent etc.
But remember FCTM:
Many engine surge or stall events are recoverable and permit continued engine operation. Stabilized engine indications and decreasing EGT indicate the surge/stall has cleared. In these cases, the engine may be operated normally, or at a reduced thrust level which is surge and stall free.
Only shutdown if you really need to.
Also
Loss of parameter:
Flight Crew should be advised that the loss of an engine parameter indication while inflight does not necessarily constitute a situation that would require the engine to be shutdown. As long as there are no other accompanying indications of an engine malfunction, the engine can be operated normally for the remainder of the flight.
Vibration:
However, high AVM indications combined with other abnormal engine indications, extreme vibrations, severe damage, and/or engine limit exceedances should be addressed in accordance with the appropriate Non-Normal Checklist.
B flight ops review 737-33
What checklist do you access if there is no response or abnormal response to TL movement?
Consider phase of flight in answer.
When might you consider a quick engine shutdown.
Engine Limit or surge or stall.
Any phase of flight.
From FCTM:
All turbo fan engines are susceptible to this malfunction whether engine control is hydro-mechanical, hydro-mechanical with supervisory electronics (e.g. PMC) or Full Authority Digital Engine Control (FADEC).
Engine response to a loss of control varies from engine to engine. Malfunctions have occurred in-flight and on the ground.
The major challenge the Flight Crew faces when responding to this malfunction is recognizing the condition and determining which engine has malfunctioned.
The Engine Limit or Surge or Stall NNC is written to include this malfunction.This condition can occur during any phase of flight.
Failure of engine or fuel control system components or loss of thrust lever position feedback has caused loss of engine thrust control. Control loss may not be immediately evident since many engines fail to some fixed RPM or thrust lever condition. This fixed RPM or thrust lever condition may be very near the commanded thrust level and therefore difficult to recognize until the Flight Crew attempts to change thrust with the thrust lever.
Other engine responses include: shutdown, operation at low RPM, or thrust at the last valid thrust lever setting (in the case of a thrust lever feedback fault) depending on altitude or air/ground logic. In all cases, the affected engine does not respond to thrust lever movement or the response is abnormal.
Since recognition may be difficult, if a loss of engine control is suspected, the Flight Crew should continue the takeoff or remain airborne until the NNC can be accomplished. This helps with directional control and may preclude an inadvertent shutdown of the wrong engine.
In some conditions, such as during low speed ground operations, immediate engine shutdown may be necessary to maintain directional control.
So on the ground veering off the runway or unable to stop taxiing…
What checklist do you run if flames are reported in engine inlet or exhaust in flight?
Engine Limit or surge or stall.
Dual engine failure.
What are your initial target speeds?
“AP off - Manual flight - Capt PF”

‘have fuel, fuel pumps are on,
and no severe damage so relight possible’ Try anyway obs…
Turn toward nearest airport/ off airport landing spot.
Restart attempt as soon as possible to take advantage of higher engine RPM at point of flame out - gives best windmill relight chances.
Memory items…
At monitor EGT on start:
Capt Mayday call/ 7700/ area qnh if req. and wind up speed as required.
At/Abv FL270 = 275kts
Blw Fl270 = 300 kts - ie get in windmill window.
These are the QRH speeds to get a relight, but some consideration to min drag speed is due if terrain a serious factor. Do you have any fuel?
During start attempt use lower of EGT redline or EGT start limit line if displayed. Hung start is STAGNANT rpm and INCREASING EGT, don’t abort too early.
Restart attempt as soon as possible to take advantage of higher engine RPM at point of flame out - gives best windmill relight chances.
Consider turn off track for traffic and consider diversion/terrain/weather.
Requesting area QNH - maybe maybe not depends on alt, could be a bit distracting high alt.
Traffic position report all stations PAN call.
You maintain transponder 1 so 7700, not sure if tcas or adsb still works.
AP lost - revert to basic modes, I’m pretty sure you’ll have lost VNAV/LNAV
Only Capt screens so LHS flying.
LHS will be hand flying - area of responsibility..
Engine start lever PM domain, on ground it is the captain during engine start.
This is reverse of normal - will need CRM.
You have capt screens and compact eng displays.
Get start attempt going ASAP to take advantage of high post flameout rpm - do not delay till you are in envelope!
Get speed up and lower altitude quickly to get in windmill envelope.
Windmill envelope is AFM demonstrated - doesn’t mean a windmill might not work outside.
Only after a start attempt get APU on, but don’t delay this too much.
Although Elec sys fcom pages only recommend starting apu below F250…
Inflight start:
During in-flight restart attempts use the lower of the EGT redline and the EGT start limit redline, if displayed. A hung or stalled in-flight start is normally indicated by stagnant RPM and increasing EGT. During start, engines may accelerate to idle slowly but action should not be taken if RPM is increasing and EGT is not near or rapidly approaching the limit.
Don’t confuse APU start gen trip on with engine return.
Oil qty indication as low as zero is normal if windmilling N2 RPM is below approximately 8%.
The checklist doesn’t talk about closing thrust levers but I’d guess this is a good idea. You do in an engine inflight start.
What do you lose?

Engine Tailpipe fire - ie no engine fire warning on the ground:
This it’s not a memory item… But used to be…
But ESL to cutoff (ie shutoff fuel)

a good start…
Engine Fire CL is inappropriate.
You would probably get this during an engine start.
Worst case scenario would be after shutdown with no APU available.
From FCTM:
An engine tailpipe fire can occur while on the ground, during engine start or shutdown.
Since a tailpipe fire develops in an area of the engine without fire detection capability, the engine fire warning will not show.
Communication with a trained ground crew member via the flight interphone or hand signals can provide awareness of a tailpipe fire. Reports of a tailpipe fire may also be received from ATC, Cabin Crew, or Flight Crew members of nearby airplanes.
Engine tailpipe fires can occur due to the following:
* engine control malfunction
* excess fuel in the combustor, turbine or exhaust nozzle
* oil accumulation in the hot section flow path or exhaust system.
If a tailpipe fire is reported, the Flight Crew should accomplish the NNC without delay. Flight Crews should consider the following when dealing with this situation:
* motoring the engine is the primary means of extinguishing the fire.
* to prevent an inappropriate evacuation, flight attendants should be notified without significant delay.
* communications with ramp personnel and ATC are important to determine the status of the tailpipe fire and to request fire extinguishing assistance
* the engine fire checklist is inappropriate because the engine fire extinguishing agent is not effective against a fire inside the tailpipe.
Runaway Stabilizer.
Reducing airspeed reduces air loads to help control. AP and AT are out for remainder of flight.
You may conduct mem items simultaneously.
Did trim stop when you disconnected AP - consider jammed FC’s
Cutout switches do not require confirmation
1 unit trim is 15 turns of wheel
Consider seatbelts cabin management.
FCTM:
A runaway stabilizer condition can be recognized by continuous uncommanded movement of stabilizer trim, or if stabilizer trim is occurring in a manner that is not appropriate for current flight conditions. During manual flight or flight with the autopilot engaged, automatic stabilizer trim can be commanded by the Speed Trim System or autopilot trim. Since commanded stabilizer trim can occur automatically, the pilot needs to consider the existing flight conditions to determine if a runaway stabilizer condition exists. For example, some stabilizer trim movement can be expected to occur during speed, altitude, or configuration changes.During a runaway stabilizer condition the crew should maintain airplane pitch control through the use of the control column, main electric stabilizer trim, and thrust levers. The control column must be held firmly before the autopilot (if engaged) is disengaged to maintain airplane pitch control and retain any elevator commands from the autopilot. After the autopilot and autothrottle are disengaged, use the control column and thrust levers to establish appropriate pitch attitude and airspeed. If uncommanded trim motion continues, it may stop when the control column is displaced in the opposite direction and the control column cutout is activated. Use main electric stabilizer trim to reverse any stabilizer trim movement and to reduce control column forces. Sustained use of main electric stabilizer trim may be needed. It is important to note that even though the steps in the Runaway Stabilizer checklist are sequential, these steps can be accomplished simultaneously. If uncommanded stabilizer trim movement continues, place both STAB TRIM cutout switches to the CUTOUT position. Manual stabilizer trim should then be used for the remainder of the flight.
Manual Stabilizer Trim
During some non-normal conditions, manual stabilizer trim may be needed. The Flight Crew should use main electric stabilizer trim, if available, to ensure the airplane is in-trim prior to relying on the use of manual stabilizer trim. Manual stabilizer trim is intended for small corrections from an in-trim condition. If manual stabilizer trim is needed, make sure both STAB TRIM cutout switches are in the CUTOUT position prior to extending the manual trim wheel handles. Anytime manual stabilizer trim is in use, keep the manual trim wheel handles extended. This allows easy access for the pilots to make required trim changes.Note: Moving the STAB TRIM cutout switches to the CUTOUT position can result in illumination of the SPEED TRIM FAIL light. This can occur during manual flight if the Speed Trim System determines a need to trim but the system is disabled

FCTM:
If an unreliable airspeed event occurs during takeoff at or after V1, maintain takeoff thrust, smoothly rotate towards 15° pitch attitude and establish the normal takeoff pitch attitude target, retract the landing gear, and maintain flap configuration. Climb at the normal takeoff pitch attitude target until reaching a safe altitude (acceleration height) and do the Airspeed Unreliable NNC.See discussion regarding normal takeoff pitch attitude target in Chapter 3, Takeoff, Rotation and Liftoff and Typical Rotation.
Approach and Landing Airspeed Unreliable
Approach:
If available, accomplish an ILS or GLS approach. Establish landing configuration early on final approach. At glideslope intercept or beginning of descent, set thrust and attitude per the QRH tables and control the rate of descent with thrust.
Landing:
Control the final approach so as to touchdown approximately 1,000ft to 1,500ft beyond the threshold. Fly the airplane on to the runway, do not hold it off or let it “float” to touchdown.Use autobrakes if available. If manual braking is used, maintain adequate brake pedal pressure until a safe stop is assured. Immediately after touchdown, expeditiously accomplish the landing roll procedure.
Go Around Airspeed Unreliable
You may lose both side FD pitch guidance on GA.
You get pitch back with new pitch mode and lose roll guidance on dud side.
You can use TOGA (to exit APP mode) on GA.
Don’t use TOGA ISFD only.
From FCTM
Prior to Approach
In the event that either the Captain’s or First Officer’s airspeed indication is reliable, the flight directors on the reliable PFD can be used during an approach.
When TO/GA is pushed in the event of a go-around or missed approach, pitch guidance may automatically be removed from view on both PFDs as a result of a disagreement between PFD flight director pitch guidance.
Flight director roll guidance remains available.
Flight director pitch guidance returns to view on the reliable PFD when a pitch mode change is made or automatically occurs.
Simultaneously, flight director roll guidance is automatically removed on the unreliable PFD.
Refer to the Flight With Unreliable Airspeed, go-around table prior to starting the approach.
This provides a target pitch setting in the event that flight director pitch guidance is removed.
Note: If the APP mode is used during the approach, it is important to exit the APP mode in the event of a go-around.
This can be done by pushing TO/GA.
Note: If only the standby airspeed indication is reliable, do not use TO/GA.
On Approach
If an airspeed unreliable event occurs during approach, and a go-around or missed approach is necessary, execute a go-around using go-around thrust and smoothly increase pitch towards a normal takeoff pitch attitude. Upon reaching a safe altitude set the target pitch attitude and thrust settings from the Airspeed Unreliable NNC and accomplish the checklist.
AofA disagree
What indication might help?
Go to Unreliable Airspeed checklist.
ISFD speed.
FCTM:
If the Flight Crew suspects that the unreliable airspeed condition may be caused by erroneous AOA, in addition to the above flight deck indications, the AOA DISAGREE alert is shown on both PFDs and erroneous minimum and maximum speed bars are shown on one side. In this situation, comparing indicated airspeed on the PFDs with the ISFD can help the Flight Crew determine a reliable airspeed indication
