Stall Recovery Technique in JETS

[nmejiab]

Hello:

I'm a EMB190 FO. Last week I had my proeficiency check and the Civil Authority guy told us about "their" new standard regarding altitude loss in the satll recovery (clean, landing and take-off). I have one question about the landing configuration recovery. The Civil Authority require a 0 feet tolerance.

If I'm already descending during an approach, trying to not loose a single feet wll it make it easier to enter a secondary stall?

I thank in advance any comment you guys can do. I'm trying to find some arguments to try to remove that new "standard" that I think is very dangerous.

Training versus Real Life.

Usually in a training scenario the student is expected to maintain a constant altitude throughout the entire manuever: Entry, Stall, Recovery.

So the "Approach to Landing Stall" exercise isn't really meant to duplicate what would happen on an ILS. It's more about demonstrating good aircraft control and learning the different characteristics of the airplane (clean vs. configured).

Good luck.

I don't have the relevant AFM .. but most such documents specify the height loss to be expected in a stall recovery ... ?

First indication

I'm not speaking for any "Civil Authority", but at my company we train to recover at "first indication" of stall, that is to say, buffet or stick shaker.

In my airplane, in the landing configuration, you experience stick shaker before buffet so it's entirely possible to recover without any loss of altitude.

Of course I think +/- 0 feet is asking a little much but any proficient ATP should be able to manage +/- 50 feet! That's 100 feet to play with.

stall recovery in jets

i currently fly a B732...during my initial rating, and since then in all recurrencies we do TWO types of stalls...one at which GROUND CONTACT IS NOT A FACTOR, in this one you are allowed to loose height...another is when GROUND CONTACT IS A FACTOR, which the aircraft is in a landing configuration, take off configuration or in landing configuration in a turn...in this second one, altitude loss is not permitted as you are close to the grond...

I think -0 feet is a bit of a tough deal, but the E170/190 will recover quite nicely with less than -20 feet of altitude change from a level flight entry to stick shaker in any configuration with standard recovery technique.

When we practise CAT IIIa / IIIb ILS approaches or CANPA, the standard altitude loss considered in case of a missed approached (with or without A/P engaged) is 50 foot (at least on the B-767) and must be considered when adjusting the minimums (CANPA only since it's expected that the airplane touches down if the G/A is performed below 50 feet threshold elevation on a CAT IIIb approach).
So, if even with A/P ON one must consider this 50 foot loss for the G/A in a landing configuration approach to a runway, think guess this zero altitude loss tolerance for a manual G/A or landing stall recovery it's quite too tight, isn't it?. Nevertheless, I'm not an instructor so I'm not really sure what are the maximum tolerances we can have during this manoeuvres but normaly it ranges from 50 to 100 foot loss.
