Ask The Pilot

Good afternoon JB and our other resident Pilots.

Just a quick question.

Today at OOL I observed a captain and first officer taking JQ11 (Operated by the B788 for the first time today) to NRT with another captain in tow. The Captain in tow had slightly different Epaulet Slides (4 stripes with a metal pin or pip at the end next to the shirts collar), A different uniform and an Australian Government Lanyard.

Unfortunately I was called away to other duties before having a chance to chat to any of them and I was wondering if it could of been someone from CASA and what they may have been doing. Would it have been something akin to certifying the new type on that route or conducting some kind of audit?

Thanks!

CASA pilots often fly as part of their oversight of all of the airlines...and that's especially the case when a new aircraft is involved.
 
What, the fact that it still flew and climbed, a long way, without engines? That's what a heap of kinetic energy can do. If I recall correctly the engine start systems were modified to ensure relights when needed.

Some reading here: 16 January 1975 | This Day in Aviation

From that article on the F15 (slightly modified for the exercise): ¨a thrust-to-weight ratio of 1.4:1¨. that must be fun to fly.
 
I saw my neighbours wife this morning and she said it was a week of sims - but he passed. Now to get him over for a drink so he can share with me - because his wife is over listening to how good he was :D ;)

Over with him now and he is about to read your sims, jb747.

Simulator time again. I've been away on fairly extended leave, so I spent about a week with my head in the books prior to this exercise.

Firstly, in relation to a question about Virgin's sim sequences a while back, QF is changing the system they use, so that we'll now do two sims very close together (apparently they have to be within two months, but will try to make them within a couple of days), followed by a longer break. Still four sims a year.

The exercise that I've just done was around Hong Kong. Windshear warnings occurred throughout the exercise, and appeared to be almost randomly inserted, so some on approach, and others on departure. Just to welcome me back, the very first take off resulted in a low speed abort, when the aircraft failed to give the annunciations that we expect at the start of the take off roll (related to nav, pitch, and auto throttle modes).

Then took off from 25L. Manually flew part of the departure, and then both FO and I did some flying on the standby instruments (all of the fancy screens turned off). Given that the display is only about 2 inches across, it's hard to see, much less fly accurately, but it can be done. To get to that point though, you would need at least six other full sized screens to have failed, so not likely.

After that, we flew up to the north and set up for a VOR approach to 25R. Became visual at the bottom, but got a windshear warning at about 400 feet. Once we'd sorted that out, IP back to just before the shear started, and completed a visual landing. One of the aims of this exercise was to do a bunch of landings at config 3 instead of the normal full...basically less flap. It's more floaty in the flare, but it's a safer configuration to use in expected windshear (as it has less drag).

Because there were a lot of small items to be done, this exercise included a lot of IPs...jumps to a spot in space and different configurations. They can be disconcerting, and it's easy to lose track of what is going on, so it really relies on the instructor making sure you're on top of the position and configuration before releasing the sim. But, they allow multiple looks at procedures without having to go through setting them up each time.

Back to the other runway, and this time, just after V1, I drop dead. When the FO got no response to 'rotate' he quickly took over. Exercise over once he has the a/p engaged, and has completed the clean up and checklist.

IP back to the runway. This time we take off, and fly straight into a windshear event. These aren't mild either, going from somewhere around 20 knots of headwind, to up to 40 tail. Once that is sorted out, IP back and fly an ILS to 25R. Then IP back again, and fly in visual conditions but without any approach slope guidance. Land.

Now the FO has a go. Takes off on 07, and comes back for the VOR 07L. Windshear again. Sort it out and IP back for an ILS 07L, and land.

Time for a coffee break. When we come back, it's all low vis sequences. These are always flown by the captain. So, start with a take off in 175 metres vis. Engine failure, and abort. Exercise stops once you complete the checklist and PAs. IP back to the start of the runway, and go again. This time an engine fails just after V1. Continue take off. Because of the high terrain all around HK, there are special procedures to be flown instead of the SIDs. Once sorted out, for the purpose of the exercise, restart the engine. Carry out a Cat IIIA approach to 25 (50' minima). Go around at about 200' as the reported crosswind is outside limits. Carry out the full go around procedure (which is quite complex) and then another approach. Land off that.

FO now flying. IP to about 150 miles SE of HK, inbound at FL350. Bang...simultaneous engine failure, giving hull breach, and depressurisation. The plan (as of course we knew it was going to happen) was for the FO to be pilot flying and to manage to multiple problems. But, in the sim things don't always go quite to plan. As I dropped the oxygen mask over my face and it retracted, it snapped my glass's frame. So, now I really couldn't see (close up) all that well, certainly not well enough to be able to quickly read the ECAMs that we needed to do. So, I took over control, and got the FO to take that role. The idea in the sim is that you always just deal with issues as best you can...and fractured glasses at an inconvenient time, is just one of those issues. Problems sorted out, and back at 10,000 feet. IP back to HK for the FO to fly a couple of visual approaches. Exercise over.

My neighbour read your sim exercises with great interest last night and commented on your experience jb747 - everything checked out. VA also have 2 days of sims, so that correlates to QF's experience.

He showed me copies of his most recent sims over both days (he has copies of all his sims since AN days, so that encompasses QR ones as well). The first day included take off and landings into NAN then changed to a take off from ZQN with max weight and engine failure at 400m, bleeds off, flaps 35 (I think I got that right...) with a landing at alternate Palmerston North IIRC. Final airport was also HKG and various issues.

The second day was based using SYD and MEL and take off and landings in low vis and various failures with alternating PF's.

I'd be interested to know from JB or others why you might go to flaps 35 in this situation... I would have thought you'd want as little drag as possible with one engine inop to maximise climb performance, particularly in a mountainous area like Queenstown?

Also to QF WP - did your neighbour say why he was practicing ops round HKG when VA don't operate there?

Cheers!
 
I've heard it mentioned that prior to landing engines are pulled back to idle. What does idle mean? Are the engines essentially not providing any thrust? At what point of the landing does this happen?

On takeoff, I've noticed the seatbelt sign going off and then very quickly on again. At this point the cabin crew will usually get up out of their seats and prepare for service. Is this initiated by the flight crew? At what point?

Thanks!

Flap 35 (if it exists at all) sounds like a landing flap setting. Takeoff would use a setting of 5, 15 or 20 (which will vary with type). Airbus don't talk degrees, but we can use 1, 2 or 3. The choice of setting will depend upon the runway length and the local terrain. Less flap will give a longer take off roll, but will have a better climb gradient.

You pull the thrust levers right back to the minimum stop. The engine fuel flow will reduce to the lowest allowed by the fuel control unit. Idle produces around 5-10% of full power thrust. So, they're still doing a bit of pushing, but not much. The actual idle rpm varies with the situation. Idle on the ground is a lower speed than is allowed in flight. Accelerating away from idle can take quite some time, so it isn't a thrust setting that you want unless you're very close to the ground.

In the A380 we select idle at about 30 feet. It varies a bit on the day. If you're fast you can afford to do it a bit earlier..conversely, if slow, then you need the power for a bit longer. You normally want it gone by the time you get to the flare, otherwise the aircraft tend to float. And if you touchdown with it still applied, the spoilers won't rise, until you do pull the levers back. It isn't by the numbers though...you get rid of the power when you don't want it any more.

On takeoff, I've noticed the seatbelt sign going off and then very quickly on again. At this point the cabin crew will usually get up out of their seats and prepare for service. Is this initiated by the flight crew? At what point?

That is a system used by some airlines, and is not something that I like. All the flight crew do, is to cycle the seat belt switch. The drawback is that the cabin crew are moving about with the signs still illuminated, so it has the effect of teaching people that the signs don't mean much. Our system is signs on (in flight), everyone sits down.

I might have got the flaps setting wrong - we did have a 7 hour session together.

No, he didn't mention why HKG. I'll ask
 
With this talk in the media about QF flying over Iraq with the media quoting an unnamed "Qantas pilot" saying they didn't want to fly there...

If the airline has filed a flight path, in this case out of DXB over Iraq to LHR, can you just ignore that, take on more fuel and ask ATC to direct you out over Egypt?
 
Did a sector on a DHC8-400 the other day, normally have row 1 or 2 and on this flight was seated in 1, this was a new aircraft and it had window shades (up-down) and they had a placard "To remain up at all times". All the other -8 400 series that i have flown on do not have window shades and the FA said that it was a late order ( or maybe cancelled) from the factory that had the shades already optioned. My question is why do QF order these aircraft without shades, and then after one has arrived, require the fitting of a placard, effectively saying,never to be closed?

I'll put this question to a friend who should know the answer (both tech crew and maintenance background on Q400) and report back, hopefully tomorrow.
 
The Dash does not have a crew viewing portal through its door, hence Row 1 needs to be available at all times.

The Dash does not have a crew viewing portal through its door, hence Row 1 needs to be available at all times.

Which inspires me to ask something I've long wondered .. maybe more 'ask the engineer' but I'll see how we go. On most / many jets, the crew viewing portal in the door is (relatively) tiny and when you look through it, the field of view is pretty small. When the crew is seated, I don't think they can see much meaningful at all.

Is the reason for this engineering - ie strength and integrity of the door unit? I guess long experience tells us that it doesn't matter much (or maybe we just don't know) and the return question might be 'what do you want them to see?' . But there are occasions when crew do need to see whats happening outside and I would have thought that this position would be as good as any, or better than going into the pax area and peering across those seated.
