I recently discovered something interesting about ACARS. There’s no error detection or correction. None. To be honest, when I was told this I wasn’t exactly surprised, but now that I’ve had time to think about it – I’m somewhat appalled. Note : I have recently received feedback that some of my contentions in this article […]

777 Autoflight Speed Protection – Asiana 214
I was asked recently to write for an internal newsletter to provide some Boeing 777 specific information to non-777 pilots on the role of the 777 Autopilot Flight Director System (AFDS) and Autothrottle in the Asiana 214 accident. The following article is based on that contribution.
B777 Cruise CoG
Recently I’ve had a couple of discussions about the Cruise Center of Gravity (CoG) setting/default in the B777 Flight Management Computer (FMC). Basically the 777 FMC comes with a default Cruise CoG setting on the PERF INIT page (shown). The FMC has a default value (small font) and valid pilot entries vary from 7.5% to […]
50,000 volts into the MCP
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.
LNAV for a Localizer Approach
I was recently asked whether we could still use LNAV to fly a Localizer Instrument Approach, and whether that was the preferred mode. This question was asked during a briefing on PBN which has caused some confusion. Recently we’ve seen some changes in the way we do aircraft Navigation, or at least in the way […]
The Boeing 787 – Evolutionary and Revolutionary
The Boeing 787 is certainly a revolutionary step from anything Boeing has done recently – and from anything else Boeing seems to have planned in the future it would seem, judging by the 737-Max. From what I can glean on the web, the 737 Max while incorporating some revolutionary technologies in the engines and airframe – is […]
Decision Making Models
We are reviewing Decision Making Models at the moment. On the 777, we’ve used FORDEC, which is very close to the European model, except we’ve replaced “Check” with “Communicate”, which may or may not have been a good thing. Other fleets in our airline are using GRADE or NMATE. There are several reasons why Decision […]
Runway Change on Departure
A runway change can be highly destructive to mental model the crew establish during preflight of the aircraft departure. Dozens of decisions, selections and entries are often required to be evaluated and implemented – often while the engines are running and aircraft are waiting behind you.
Relief Crew on the Flight Deck
The presence of additional flight crew on the flight deck over and above the standard two crew complement can be a challenge for some Primary Crew to manage. The role of a Relief Crew member on a flight deck can also be a challenging one. Decades of research and documentation clearly define the roles of Cisco and Pancho on the flight deck. No one defines what Diablo is supposed to do …
So what is the Killer EFB App?
Today I am at Day One of the Airline & Aerospace MRO & Operations IT Conference, looking primarily at EFB and EFB enabled systems. As I sort through the assault of information that comes at you at these events, I’ll be musing here on Flight.Org on what I’m learning. Whether seeking the heftily priced Class Three […]
EFB Adventures
My airline is currently looking at various options for an Electronic Flight Bag (EFB). Originally meant to come with our spanking new 777-300ER’s, they didn’t – for a variety of timing, manufacturing and political reasons. Thus we have an exceedingly handy clip/chart holder and a neat little cupboard where a hundred thousand dollar EFB should […]
