View Full Version : Callouts for Escape Maneuvers

Wondering whether any airlines have standard calls (by Pilot Monitoring to the PF) to be used when the electronic "Windshear" "Terrain" or TCAS "Climb Now" etc are heard. I have never thought about this before it being self evident what the next action is. But one of our F/Os just called "Go-around" in response to a GPWS terrain warning and it confused the whole show....they did a go-around rather than the escape maneuver. As it happens it was quite safe but might not have been at another time and place.
Any ideas on what the PM should say...?
Thanks

Just my 2 cents, I would say that if the go around was predicated on predictive wind shear, a standard go around is acceptable:confused: , at our company, "go around flaps", if you were already encountering wind shear, I would say "wind shear go around" would be in order to help remind the crew to not change the current configuration.

Hello 019360,
I do not think that you need any specific callouts for these kind of situations as Boeing states in the QRH that any warning given by the (E)GPWS must be followed without hesitation. Guide lines are given to properly execute the escape maneuver, and adding any supplementary callouts would go against QRH statements. That's my humble opinion anyway...:)

That's why in my company the callouts by the Pilot-Not-Flying should be 'PULL UP' or 'WINDSHEAR', causing the respective recocery-procedure.

I had some similar expiriences in SIM-Training, if PNF calls for 'Go-Around', PF will in most cases call for a flap-reduction.

SOP/Standard Callouts Airbus sigle aisle family:

MEMORY ITEMS:
The aim of such callouts is to callout the apropriate procedure by calling out, in most cases, the title of the procedure. This will allow the crew to be aware of the situation and be prepared to react (crew coordination, task sharing and communication)
GPWS
As soon as avoidance manoeuvre is envisaged.
"PULL UP TOGA"
WINDSHEAR
"WINDSHEAR TOGA"
UNRELIABLE AIRSPEED INDICATION
"UNRELIABLE AIRSPEED"
TCAS
As soon as "TRAFFIC" warining is trigggered
"TCAS - I have control"
EMREGENCY DESCENT
"EMERGENCY DESCENT"
LOSS OF BRAKING
"LOSS OF BRAKING"

I think it is quite in-line with ideas posted above. It is essential that crews do not mistake calls so the less calls the better. The TCAS call was introduced only lately to help prevent dual inputs during RA response, this is specific to Airbus FBW cockpit design. The above is original manufacturer's guidance.

In my company the respective calls are:

"Pull up, go-around" or "Windshear, go-around" Presumably to reinforce the situation and identifies the appropriate go-around technique to be used.

I would not add 'go around ' call to any windshear or terrain warning ,as any atempt to do a normal go-around will compromise safety.
Few important differences between gpws warnings and 'go-around':
*disconnect a/p and a/t
*AGRESSIVELY apply maximum thrust
* initiall pitch 20 for 'terrain' (or 15 for widshear)
*go to PLI or stick shaker if needed.
*retract speedbrakes
*DO NOT CHANGE configuration.

Any attempt fo do a normal go-around will not respect the above requirements, and may drastically compromise safety.
I would take the FDR data for the specific flight ,and discussed it with both pilots involved, and even with the rest of the pilots, so to make clear what the trajectory was,the ground clearance , and what would be the difference between go-around and terreain avoidance manouvre.

Thanks,

That all helps.

Well, to me, it doesn't sound as if it was ...quite safe....

It sounds as if it was uneventful. Big difference.

Just because nothing untoward or unpleasant happens does not mean that a particular action was safe.

Like playing Russian Roulette with a revolver loaded with just one cartridge.

I doubt you would call that safe, just because nothing happened.

Actions can easily be classified as unsafe, even if they have little chance of going wrong. Those unsafe actions that have a high chance of going wrong are generally called dangerous.

Like playing Russian Roulette with a semi-automatic loaded with just one cartridge. ;)

Our company just uses the word "ESCAPE" as SOP call for any windshear or EGPWS encounter. It also proved useful during a recent TCAS climb RA at very low altitude.
We are of the opinion that pilots should not waste time thinking 'What am I going to say now exactly, uhh, oh sh*t I don't remember the exact wording' so one size fits all.
Just my 2p of course, best regards, PD.
