Managing a departure with a performance limited takeoff can be one of the more challenging tasks that face the Captain of an aircraft today. It all sounds simple enough in theory. Based on the Airport/Runway, Ambient Weather Conditions and Aircraft, a computer will spit out down to the kilogram how much weight you’re allowed to lift off the runway. From this number a passenger/cargo and fuel load is determined – and off you go. But all is not as it seems.

B777 EICAS/ECL Guide
Some time ago I wrote down all that I had been taught and learned about operating the Boeing 777 Electronic Checklist (ECL) in conjunction with the onboard Electronic Indication and Crew Alert System (EICAS). I’ve updated it along the way as I became an instructor and it’s become more and more of a formal document […]
B777 Slats Drive & Flap Retraction
The recent recurrent training phase included a SLATS DRIVE failure during takeoff at high weight. At some point, the crew is confronted with the decision about whether to retract flap or not. The results of doing so would not be so amusing had I not done the same myself ……
How Slow Can You Go …
Recently I was asked to write an article for an internal company training newsletter about flying slow. Having finished it I thought I’d replicate it here for others. Note the following article is aimed specifically at the Boeing 777 series aircraft, although the concept is common across all transport category jet aircraft flying slow at […]
B777 TAC – Thrust Asymmetry Compensation
As Boeing’s first Fly-By-Wire aircraft (although not necessarily fly-by-wire by the Airbus definition) the 777 introduced a flight control augmentation system that the first fly by wire Airbus aircraft did not – Thrust Assymetry Compensation, or TAC. The basic problem is clear. During an engine failure on a twin wing-mounted engine aircraft there is an […]
Cold Temperature Altimetry Corrections [Corrected 26Jun17]
I’ve been looking at Cold Temperature Altimetry Corrections in anticipation of potentially operating into such environments again in the near future. While my professional past includes operating the 777 to Moscow, Baku, Seuol, Beijing and a few other cold temperature destinations – most of the last decade has been focussed on Australia, Los Angeles, and […]
So, Who should Fly?
Currently I’m evaluating research on the roles of the Captain vs the First Officer in the detection and correction of procedural errors on the flight deck. Fortunately I’m not looking at our entire operation, just one small corner of it. First, some background. Delaying Final FMC Performance Data Entry Our SOP’s are pretty much based on Boeing’s […]
Totalizer vs Calculated Fuel
I’m working on an update to the Practices and Techniques document I developed several years ago. While this has been a published document in my airline for several years, it was recently taken offline and is now a training background reference, as was the original intention of it’s development. Just one of the many subjects […]
Low Missed Approach Altitude Restriction
A question concerning a recent change to the missed approach procedures in Dubai UAE (OMDB) has raised some interesting points about the 777 in this flight regime – high thrust, low altitude, high pilot workload; and ATC procedures that would seem to be not too well thought out. Specifically the new procedure introduces a not-above […]
777 Normal Procedures Flow Diagrams
What’s been missing for our documentation for some time is decent diagrams showing the normal procedures flows. The B777 normal operation centers around these flows, and the normal procedure ECL checklists that follow. For Normal Operations – the ECL Checklist is a “Done” list, where all then items you run through on the checklist should […]
Deciding to Stop
Many years ago when I was a junior FO new to the 777, I did one of my first recurrent checks in the simulator with an Examiner who started asking questions about the takeoff inhibits system. After several such questions – of both the Captain and myself – it became increasingly apparent that not only […]
EICAS VNAV STEP CLIMB
The introduction of the [] VNAV STEP CLIMB checklist highlights procedural handling of EICAS/ECL and the management of enroute climbing in the aircraft. The FMC schedules step climbs throughout the flight based on the settings in the Cruise Altitude (CRZ ALT), Step Size (STEP) and potentially Step To (STEP TO) fields based on the aircraft […]
VNAV Path Intercept from Above
With the airline industry moving progressively towards GPS and GPS Augmented based approaches and away from the more traditional ground based navigation aid approaches, the use of LNAV/VNAV – with all it’s eccentricities – are becoming the norm for many airlines, rather than the exception. The boon of flying such approaches more often is that […]
Basic Modes Engine Out Drift Down
An engine failure at altitude above the maximum engine out altitude, followed by the obligatory engine out drift down is a bread and butter event for a cruise pilot. Typically this is practiced and evaulated using the highest levels of automation in LNAV and VNAV. For more information see Engine Out Drift Down and the […]
Engine Out Drift Down – and the FMA
I’m working on an update to the Practices and Techniques document I developed in 2008. While this has been a published document in my airline for several years, it was recently taken offline and is now a training background reference, as was the original intention for it’s development. Something that’s been missing for a while […]
