There has been some discussion recently around FMC scratchpad messages, their role in flight deck alerting, and an appropriate crew response. Most particularly around the habit that some crew develop – usually during transition simulator training when many spurious messages are generated and often cleared without real understanding of their meaning). We areseeing this in the sim […]
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 […]
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 […]
A while ago I scheduled a temperature inversion in a simulator session in preparation for our operation to Abu Dhabi’s summer. For further reflections see Performance Limited Takeoff and High Temperature Departure Abu Dhabi. The issue of temperature inversions and the implications for takeoff performance calculation raised so many issues that I ended up having […]
Sometimes you need to be able to calculate a limiting ZFW based on a forced change in TOW. You can use the OFP LNDG correction figure to do it. And it’s not VooDoo – just mathematics.
For the last decade or so, I have been working on a document called Boeing 777 Procedures and Techniques. It has it’s genesis in what was originally a Common Errors document based on observations of Pilot/Student actions in the Simulator – but most particularly Instructor/Examiner activity in the Brief/Sim/Debrief as well. If you would like […]
I’ve spent the better part of 15 years on the 777 preparing early for the approach and landing by setting up the FMC. Now it seems KZAK has other ideas …
Next time you reach up for something on the Mode Control Panel (MCP) – try and remember that 50,000 volts could be involved … Let me explain.
![Cold Temperature Altimetry Corrections [Corrected 26Jun17]](https://www.infinidim.org/wp-content/uploads/2016/11/ColdTemp12.jpg "coldtemp12")
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 […]
Early last year, the FAA revised the SIDs and STARs at Los Angeles KLAX airport. I don’t know if I had annual leave or missed any associated documentation, but it’s fair to say that as a fleet that basically operates into the East Coast of Australia and LAX exclusively – it was something of a baptism […]
It’s not unusual – especially during Line Training (instructors beware) for your student to generate an EICAS MAIN GEAR STEERING alert during the initial takeoff run. This results from advancing thrust prior to the main articulated gear achieving a lock during the initial takeoff roll.

Not all Engine Malfunctions are as clear as [] ENG FAIL, [] FIRE ENG or even Engine Failure Analysis. Sometimes engine malfunctions are as simple as anomalous indications of Oil Temperature or Pressure – or high engine vibrations on the Secondary Engine Display.
Weather avoidance is part and parcel of an airline pilot’s standard task list. From the Mark One Eyeball to the Rockwell Collins WXR-2100 Weather Radar there are various tools available to assist in this task; all of which leverage the training and experience an airline pilot brings to the flight deck. But my last trip […]
Recently I had a philosophical discussion on board with a crew about the use of VNAV without LNAV engaged. I was surprised to discover that they were unaware of any of the potential pitfalls associated, so I add a section to the P&T.
