EFIS PFD Attitude (iFly 747-400)

This video briefing covers the iFly 747-400 PFD Attitude Display. Discussed is the attitude display, pitch increments, bank scale, aircraft symbol, flight path vector, slip/skid indicator, and pitch limit indicator.

These videos are brilliant. There is so much information that is probably buried in the manuals but this is so more engaging! Thanks!

[@subsonicflighttraining]

Your welcome Mike, glad you are learning something from them and enjoying them, thanks for the comment...

[@asteward5586]

Many thanks for all your fantastic work! I am a Gulfstream guy and am using your material to help facilitate the transition into the 747.

[@user-mz2bb3oc4b]

Thanks Sir. I learned more than my crooked instructor taught me.

[@subsonicflighttraining]

LOL, I don’t dare ask why your instructor was crooked. Thank you, glad you find value from my videos…

1:35 How is Attitude displayed? Well, in the old airplanes it was displayed by round dials or what we like to refer to as and in the new airplanes, it's displayed on glass. It is the centerpiece of the Primary Flight Display or the PFD because again it tells us 1) information for Pitch 2) information for Roll. And when we are instrument flying, our main focus would be the Attitude portion of the PFD. 2:09

0:41 The Electronic Flight Instrument System or EFIS system. We'll be looking at the PFD or the Primary Flight Display and specifically, we're zeroing in on the Attitude Display of the PFD. So how is Attitude generated in a jet aircraft? We will typically have an Inertial Navigation System (IRS) that can consist of Inertial Reference Units (IRU) or ADIRUs. The ADIRUs are Air Data Inertial Reference Units -- IRUs and ADIRUs are contained in one housing. Some of the more recent airplanes have ADIRUs; some of the older airplanes like the 747-400 had separate ADCs, Air Data Computers, and separate IRUs, or Inertial Reference Units. 1:35

[@Mikinct]

great video. why are bank angles on Attitude Opposite when turning compared to smaller GA planes? I heard you state that you turn to where the pointer is to "Get out of an issue?" is that the main reason they reversed the pointer?

[@subsonicflighttraining]

Well, I’m not sure, but I thought most GA planes also show the aircraft symbol, bank pointer, and Sky pointer. When you bank right, the bank pointer will show you in a 30 degree bank turn to the right, but the Sky pointer will be off to to the Left showing which way to roll out to wings level. In Upset recoveries in jets, we always want to turn toward the Sky Pointer to unload the wings…

Thnks sr.

Most welcome...

[@jyotipandit4241]

Nice speech about EADI

[@subsonicflighttraining]

Thanks jyoti, on this airplane it is called the PFD, on jets like the 757/767, it is called the EADI.

[@topcopy98]

The bank indicator is counterintuitive. For some novices that could be disastrous. And it probably has been!

[@subsonicflighttraining]

Yes, I can see why you would think that since it is opposite the turn. I primarily look at the airplane symbol in relation to the blue sky and brown earth to know which way I am turning in conjunction with what the Flight Director is telling me. To go back to level, always turn the shortest direction toward the sky pointer.

[@topcopy98]

Thanks.

Your welcome Dan...

[@subsonicflighttraining]

@Ricky Xexh For an experienced instrument pilot, we are trained in the proper use of the bank indicator. In Upset Training at the airline level, we are also trained in recognition and recovery from extreme attitudes even almost inverted. I can see why a newer pilot can be confused why the indicator displays opposite the turn. The sky pointer displays how to get back to level flight. If you are in a left turn, the display goes to the right indicating to go back to level flight you need to bank right, which will lessen the bank and return you towards level flight. In extreme attitudes, you always want to turn in the shortest direction towards the sky pointer. Here is an interesting study on roll rate reversals and mis interpreting the display, journals.sagepub.com/doi/full/10.1177/0301006619901053

[@CraZy291]

Is the difference between the pitch angle and the FPV/FPA the AoA?

[@subsonicflighttraining]

Yes, the difference between the longitudinal axis of the jet and the horizon is the pitch angle. The difference between the pitch angle and your actual flight path or the relative wind is the AOA. The FPV shows your actual flight path versus the airplane symbol, which shows you your pitch attitude in reference to the horizon.

[@CraZy291]

@@subsonicflighttraining Thanks a lot. I feel like I'm getting there. Tried it out in P3D with a 737 with the PFD AoA indicator and compared pitch vs FPV, which was insightful. Now on to understanding the role of flaps and slats.

[@subsonicflighttraining]

@@CraZy291 That would be a good topic for me to do with systems, the 400 has LE Flaps and TE Flaps that are pneumatically and hydraulically powered in 3 modes, Primary, Secondary, and Alternate. Glad I could help...

[@saymyname8032]

Is the attitude on the right or left

[@subsonicflighttraining]

If I understand your question correctly, the PFD, which has the attitude in the center of the display is located normally on the Outboard Display Unit for the Captain and FO, but can be moved automatically or manually if the Outboard Display fails...

[@owenlee9772]

Why are you calling 2.5 pitch level flight? To be level would you need to be 0 pitch?

[@subsonicflighttraining]

Zero pitch would result in a descent, when these jets are in level flight you have a positive angle of attack with a pitch attitude around 2.5 to 3 degrees depending on weight. When the flaps are extended, the pitch varies from 5 degrees to 9 degrees depending on weight.

[@edoardomadrigal9063]

Can you talk about how to do a holding pattern?

[@edoardomadrigal9063]

Nice video, actually

[@subsonicflighttraining]

Edoardo, do you mean how to do it manually with HDG SEL and figuring out your entry or do you mean how to program it in the FMC? That would be a good subject to cover, I need to start making videos again, it has been over a year...
