Boeing won’t tell you what you want to know (which is usually everything) about a NnM – just what you Need to know.

Assessing System Status/Performance

Air Syn1

It’s not always the case that the aircraft’s onboard alerting systems do all the diagnosis work for you. Sometimes the crew are required to assess system status to determine the nature of a failure ..

Missed Approach Acceleration

MAPP Accel1

It’s funny how these things crop up. In late 2008 I discussed (strenuously) the issue of Missed Approach Acceleration – now I find a friend from a Middle Easter carrier is encountering the same problem.

Hi Temperature Departure – Abu Dhabi

Green is our Departure Time. Yellow is Peak Temperature.

After my recent debacle with a High Ambient Temperature departure from 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.

Performance Limited Takeoff

PerfLimited1

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.

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 …

Oceanic Arrival Transition and CPDLC Position Reporting

Oceanic1

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 …

P&T Update : GPS Failure and Subsequent Navigation

GPSFail1
This entry is part 12 of 16 in the series Practices And Techniques

We’ve become so reliant on GPS that the loss of it will come as quite a shock to today’s airline crew. The simulator doesn’t help – with a total inability to adequately simulate IRS drift. The issues are complex …

P&T Update : Flaps Drive – Where are the Flaps?

FlapsDrive2
This entry is part 11 of 16 in the series Practices And Techniques

Phase 5 training included the FLAPS DRIVE failure. It’s amazing how much you can pick up over six months of watching different crew react to the same failure – in different ways …
