DMC - Display Management Computer

 

DU - Display Unit (CRT, or "TV screen")

 

ECAM - Electronic Centralized Aircraft Monitoring

 

EIU - Engine Interface Unit

 

ELAC - Elevator Aileron Computer

 

EO - Engine Out

 

E/WD - Engine/Warning Display, upper display for aircraft systems.

 

FAC - Flight Augmentation Computer

 

FOM – Flight Ops Manual

 

FCU - Flight Control Unit (autoflight panel)

 

FMGC - Flight Management Guidance Envelope Computer, what actually performs the computations when you type into the MCDU.

 

FMGS - Flight Management Guidance Envelope System

 

F-Plan - Flight Plan

 

FPA - Flight Path Angle

 

FWC - Flight Warning Computer

 

FWS - Flight Warning System

 

GCU - Generator Control Unit

 

GLC - Generator Line Contactor

 

GNADIRS – Global Navigation Air Data Inertial Reference System, GPS, Air Data information and Inertial attitude/guidance all in one.

 

Green Dot – Best L/D (lift over drag) speed, normally used as the target speed at end of takeoff or for single engine climb out. Technically called VFTO (Final Takeoff Speed). On the Airbus a green dot on the airspeed scale.

 

IDG – Integrated Drive Generator (the old CSD and generator all in one unit)

 

INIT - Initialization

 

JFA – Just Flying Along, used a lot in ground school as in:  “…there you are just flying along when the demodulator quits causing the blah blah ECAM blah blah amber FAULT blah blah second channel blah blah and that’s all there is to it.”

 

L/G - Landing Gear

 

LGCIU - Landing Gear Control Interface Unit (I think this one is extra credit, we just called it the linguini)

 

LSK - Line Select Key (keys used on MCDU screen)

 

MCDU - Multipurpose Control and Display Unit (this is the actual box used to enter data into the FMGC, you getting all this?)

 

MMR – Multi Mode Receiver, the GPS receiver for the GNADIRS, two are installed

 

ND - Navigation Display (has all those nice little pictures on it to let you know where you are)

 

N/W – Nose Wheel

 

pb – pushbutton

 

PF – Pilot Flying, the person actually handling the control or autopilot input. Also the person to blame for the bad landing.

 

PFD - Primary Flight Display (the display you will look at the most, has airspeed, altitude, attitude, heading and more)

 

PH – Pilots Handbook

 

PM – Pilot Monitoring, the non-flying pilot, used to be called PNF (Pilot Not Flying). A politically correct way to say this guy is just a professional critic, don’t blame him for the landing.

 

PTU – Power Transfer Unit, pump that is able to transfer power (but not fluid) between the green and yellow hydraulic systems

 

QRH – Quick Reference Handbook

 

RAT - Ram Air Turbine, an air driven backup pump for blue hydraulic

 

RMP - Radio Management Panel, allows pilot to select which radio to tune or transmit on.

 

SD - System Display, lower display for aircraft systems.

 

SDAC - System Data Acquisition Concentrator

 

SEC - Spoiler Elevator Computer

 

SFCC - Slat/Flap Control Computer

 

SRS - Speed Reference System

 

THS - Trimmable Horizontal Stabilizer (did you guess it?)

 

TLA - Thrust Lever Angle, the TLA indicator is a white “donut” on the N1 gauge.

 

TOGA – Takeoff Go Around. Highest selectable thrust level. Selected by putting thrust levers in TOGA detent. Also a mode for the Flight Director.

 

TRU - Transformer Rectifier Unit, also known as TR, transformer rectifier

 

UTC - Universal Coordinated Time (a politically correct way to say Zulu or GMT)

 

VFTO – Final Takeoff Speed, normally called “Green Dot”, best lift / drag

 

WHC – Window Heat Computer

 

WTB – Wing Tip Brake

 

XFR - Transfer

 

ZFCG - Zero Fuel Center of Gravity

 

ZFW – Zero Fuel Weight

 

These are just my short list of favorites and there are many others but for the most part these should get you by.

 

Bonus – what persons names are on the Airbus instrument panels?

Answer – Max, Norm, Rose, Agent 1 & Agent 2, Rat Man

 

Extra Bonus – How do Airbus pilots celebrate their first line trip?  Answer – they have a TOGA party. I know, bad one…
