A320 EFATO Tru Simulator

[a320sim]

Hello!

So I am doing my A320 type rating in the "Tru Simulator" .

We were doing the EFATO in my 2nd session and I seem to be doing something wrong.

At V1 , Engine failure I start to press on the rudder pedal to keep directional control then a little after VR I start to pitch up but somehow I can't keep the 10-12.5 degrees pitch at all, either it goes all the way up and then I get so distraced by the pitch I loose the beta target and it's a mess end up banking a little as well.

Is there a trick to keep the pitch? Do I just rotate and leave the stick neutral immediately? I can't seem to get the hang of it and my instructor is tired of me already and he didn't give me any positive information about this he just said I should reconsider becoming a Pilot now.

Thanks

If you manage to keep directional control there shouldn't be much of a problem. Remember, the Airbus will maintain the last pitch command you gave it. For example if you leave it at 10*, it wil fly that until it runs out of fuel. So after reaching the initial 10*-12.5* your pitch inputs should be very slight only to follow the SRS commands, which is V2+10kts. Also, another common mistake I see with my students: As soon as you have 12.5* and have the beta target centered, USE YOUR RUDDER TRIM. And don't forget to ease off the pedal as you put in more Rudder trim. Count to 12 (Mississippi wise), center the FD's and hit that AP button. All this happens pretty much simultaneously. Too bad your instructor is so impatient. Any more questions don't hesitate to ask!

Thank you!

The problem I am facing is I am afraid I maybe over rotating or under rotating. I tried it multiple times and sometimes the nose just drops and sometimes it goes above 12 I am not sure how much aft pressure to use and I am afraid it will go either way!

How can I know how much to rotate? the manual says 2-3 degrees a second but how do I implement that on the side stick? Is there a way to see that on the PFD?

Simple solution.
Get the instructor up front, let him fly and show you.

Count your rotate speed. Our books say 5 sec for a normal rotate, 3* per second. After 5 years flying the Bus I still find myself counting as a check on my rotation rate.

Have you been shown the demo where you ignore tracking and just rotate and let go? The plane will look after itself pretty well, not perfect but it won’t crash.

The rotate forces are a bit weird. Often people under rotate. The forces will feel funny so you might have to change the pressure as you are trying to find the attitude.

If you can just get SOME correct rudder in, an attitude of SOMEWHERE around 10*, TRIM for a count of ten then get the AP in you’ll be pretty safe.

Try not to get too stressed, it will come.

Rudder input to maintain centreline or parallel it and hold it.

Rotate to required pitch attitude and for the first 20 secs of flight just worry about scanning pitch and speed and don’t get distracted by other issues ie rudder trim. When all settled down......look for rudder trim.....trim out control forces and engage autopilot.

Things change after rotation as flight control laws blend......if you look away during this process....it will end in tears.

For NikB

Engine​ Failure ​Above V1 from FCTM

At ​ or​ ​ below​ ​ V2​ ​ speed​ ​ after ​ liftoff​ ​ follow​ ​ SRS​ ​ pitch​ ​ command​ ​ bar​ ​ and​ ​maintain​ speed​ not less​ than​ V2.

Above​ ​ V2​ ​ Maintain ​ SRS​ ​ commanded​ ​ attitude ​ or​ ​ the ​ speed ​ reached​ ​ after ​recovery.​ The minimum speed must​ be at​ least V2.​ ​ ​

SRS commands V2 + 10 with both engines operating.

Please let your students know

For the OP.
REALLY REALLY REALLY concentrate on the yaw bar. Keep it simple.
Look through what the F/D s are commanding initially for a few seconds and LOCK your arm at 10 degrees nose up and then make very small corrections to the pitch whilst winding on about 15 degrees of trim.
The side stick should most definitely be treated like it's a merde du chien in this scenario!!!

charlies angel
you are absolutely right! Brain fart!

a320sim sorry if I confused you! Listen to charlies angel!

As for the rotation technique, if you ask 10 instructors, you'll get 20 different answers. Same with the flare. All above advise is good and valid. The demo talked about by Juliet is a pretty good way to practice!
Best of luck

So true.

2OP:

1) During taxi, try to pull stick to half-up deflection as indicated on the PFD. Try to memorize the force in hand and stick displacement, give it two or three or pulls to get the grip just before line-up.

2) During the EFATO, do not worry about the rudder input too much. Give it a push in the right direction to arrest the yaw - looking outside, and freeze your foot (heels on the floor!)

3) Apply smooth pull on the stick with your newly trained force. As the nose lifts up move eyesight to pitch symbol on the PFD, ask for L/G up and set 12,5 deg.

4) Keep your eyes on the pitch worry about nothing else. Observe the FDs come alive, then adjust to follow them. Being lazy is better - initially they tend to command up to 15 deg but do come back down to around 12.

5) Release the pull on the stick as the normal law takes over.

6) Center beta target. Then trim until you feel equal (zero is best) pressure on both of your feet. As if you planned to remove feet from the pedals altogether.

7) AP=ON.

Do not seek perfection, aim to improve bit each time. If it's not your day, another will come in the morning. There is plenty of practice opportunities througout the course.


(DO NOT EVER USE THE SIDE-STICK PFD INDICATION (german cross) TO JUDGE ROTATION DURING TAKEOFF!

[MD83FO]

Once you correct yaw, lock your foot, sort of forget about it,
next rotate smoothly let the airplane respond as you adjust those 10 degrees (ideal target for flex thrust)
You cant release the stick because you’re in ground mode
Stay attentive as the law changes to flight mode (trim wheel starts moving)
When this happens let go of the stick and trim the rudder.
Common mistake keeping the same pressure on the stick when flight mode comes in, commanding aditional pitch up and busting your V2 and loosing the maneuver.
Make shure youre off the rudder before AP ON or youll also bust the 5 degree heading change limit on the maneuver.
I dont grip the side stick i use my fingers, that way i am sure im not giving roll inputs which are unnecesary. Similar rules for the engine out missed.
