Boeing 777 Checklist Additional Notes – Paper QRH

b777-additional-notes-qrh-checklist

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 […]

Setting Final Approach Speed in a Boeing 777

SetFinalSpeed

Sometimes during a NNM (non-normal) in the simulator you see that when landing configuration is established, and the aircraft is being manoeuvred around the approach at the minimum flap manoeuvre speed, a further speed reduction will be required to set the NNM checklist specified reference speed (plus 5 knots). Exactly when to set this speed […]

Boeing 777 Main Gear Steering and Thrust Application

777-gear

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 take-off roll. Practices & Techniques : Main gear Steering and Thrust Application […]

Multiple Non Normals and VREF Setting (in a Boeing 777)

landing-777

A recent phase of training combined Engine Failure with Flaps/Slats Drive/Control failures. The sequence introduced the issue of entering a reference speed when two different checklist are specifying two different Vref settings. Practices & Techniques : Multiple NNM’s and Flap/Vref settings When dealing with multiple NNMs, crew may be confronted by conflicting requirements with respect […]

How to get a ZFW from a changed TOW using LNDG

zfw-change-777

Any long haul pilot is well aware that changes in the weight of the aircraft at takeoff have a significant impact on the fuel burn of the flight. This includes changes in fuel as well as payload. For example – If I decide that I want to carry an extra 2000 kg of fuel from […]

Landing with a Fuel Imbalance in the Boeing 777

fuel-imbalance-featured

Recently, a crew in the sim elected to hold until the completion of the Fuel Imbalance checklist before commencing an approach. Since fuel balancing can take quite some time, they were in for a long wait. This is, however, a refreshing change from the more traditional approach of the crew who decide to ignore the […]

Boeing 777 Dispatch without ECL

777ecl

This post details some things to watch ouut for when dispatching without the benefit of Electronic Checklist (ECL). It’s always fun to watch. Practices & Techniques : Dispatch without ECL When the ECL is failed or disabled: EICAS does not display checklist icons [] beside alert messages. Crew are required to use the paper checklist […]

Boeing 777 Flap Extension

boeing-777-flaps

With pilots come from a number of other aircraft types and several different airlines, including a domestic fleet, standardisation can be a challenge. The use of Flaps on approach has been in particular an interesting issue, which is hopefully address clearly in the following article. Practices & Techniques : Flap Extension During approach crew should […]

VNAV without LNAV without … VNAV

pfd

I recently 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. I should say right now that I’m not actually happy with what […]

The Boeing 777 (EICAS) Fuel Scavenge System

boeing777_fuel

The 777 has three fuel tanks (simplified version). A large center tank and two smaller main tanks (one in each wing). When refueling, the mains are filled first, then fuel is pumped into the center tank (simplified version) until either you have enough fuel, or it’s full. There are two center tank fuel pumps and […]

Non-Normal Failures That Impact Multiple Systems (You Can’t Always Get What You Want)

dont-get-what-want-featured

I was recently in the simulator with two other instructors: one was my First Officer, the other was the Sadist… ahem … sim instructor. We were running without the ECL (paper QRH for NM and NNM) and the APU was failed. Climbing through about 5000ft, Los Angeles for Sydney – we received on the EICAS […]

Clean, CON – VNAV ENG OUT – EXECute

1042653

A not-so recent amendment to the B777 FCTM (followed by a more recent update to the FCOM and QRH) instigated a procedure where ENG OUT mode of the FMC page is selected (confirmed) and exuted once tinuous thrust has been set after takeoff. While this sounds logical and orderly – as usual, the devil is […]

Boeing 777 Thrust Reference Setting Anomally

2041406

There is (what can only be described as) a software bug in the Thrust Reference setting software in the 777. While this bug manifests itself in several situation on normal and non-normal operations, it manifests significantly with flight safety implications during VNAV engine-out approaches. I discovered this issue back in the late 90′s when I […]

GPS Failure and Subsequent Navigation

gpssats

One of the limitations I’ve encountered with today’s all singing all dancing aircraft simulators is the total inability to simulate casual mapshift. As you know, the position of the aircraft (for display on the Map and as used by a number of systems) – is determined by the FMC (Flight Management Computer). Of course the […]
