VNAV is the Mode-of-Choice for Non-Precision approach. The highest level of automation; lowest flight deck workload, and a managed flight path to the runway. Mostly. Continuing in my process to convert 10 years of powerpoints into training videos – see the Infinidim VNAV NPA Training Video on YouTube – also on the Infinidim Training Videos […]

In the event of a FLAPS DRIVE failure, the checklist asks the crew to confirm the position of the Flaps. This sounds simple, but can be made complex by the situation … and the crew …

The Slats (as opposed to Flaps) are high lift, leading edge devices designed to increase the lift on a wing that’s designed for high speed / high altitude flight, not this low speed lifting 350 tons off the ground manoeuvre that we insist on performing at the beginning of every flight. Sometimes they fail and one of the possible failures is a […]
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.
This article further expounds on the paradigm established in the Post and Training Video B777 Engine Failure Analysis. The following resource material were drawn on for the contents. Airbus Flight Ops Brief : Handling Engine Malfunctions Flight Safety Foundation : Understanding Airplane Turbofan Engine Operation Rolls Royce : The Jet Engine Book. Boeing 777 FCOM/FCTM/QRH […]
Recently I was given a runway change on pushback. Despite operating out of LAX where runway change is a real likelihood, it’s been quite a while since I’ve had happen to me on taxi. Once we got the changes made – we ran the ECL Runway Change Checklist to tidy things up. Meanwhile our next […]
Infinidim Training Videos The following training videos are specific to the Boeing 777 – but might well have relevance to your operation as well. For now, they’re listed as I create them – I’ll organise later. All the Training Videos are on YouTube. Note that on the right you can also access my B777 Procedures and […]
So after a carefully walk around the outside of the aircraft where the Static and Pitot ports are checked un-obstructed; no indications from your EICAS that there are any problems with the Air Data System during taxi; you barrel down the runway, cross check the airspeed when you hear the call “Eighty Knots!” and see […]
While this article still has relevant content – the procedural aspects of the Rejected Landing After Touchdown manoeuvre have been superseded by changes to the Boeing FCTM and are reflected in the subsequent post Boeing 777 Baulked (Balked) Landing. While it’s far too early to tell what actually happened, in light of EK521 it’s perhaps germane […]
The Airspeed Unreliable scenarios is one of the more challenging non normals faced by pilots in the simulator. Of the many serious malfunctions I’ve witnessed crew deal with in the simulator – this one more than any other has caught crew out to the point of a serious limitation exeedence (high/low airspeed) or potentially an […]
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 […]
After a debacle in Abu Dhabi – and another occurrence involving offload and a 4 hour delay – I was asked to prepare some specific advice for Captains operating out of Abu Dhabi. Background Due to high temperatures, most Abu Dhabi departures during mid-Summer experience a potential performance penalty for departure; in most cases resulting […]
Boeing have begun incorporating an “Additional Information” section at the end of some NNM checklists. Presently on the 777 this feature exists for the Ice Crystal Icing, Airspeed Unreliable, and Fuel Leak checklists. It is interesting to note that despite the location of this information at the end of the checklist, the information is clearly […]
Many Airlines (or more accurately the Trainers of the Training Department) specify a series of checks at Top Of Climb. Often there’s no basis in this from an Airline SOP’s or Manufacturers point of view – which doesn’t mean they’re not valuable for situational awareness …
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.
