Hi Escape Path,
BTW, if acceleration is "too dynamic", why not pull the speed and accelerate at your own pace?
Agreed. See my post #17.
"There are two options.
1) Pull speed and control the rate of acceleration.
2) Reduce thrust manually to a sensible setting."
CaptainMongo. Thanks for the link. It makes very interesting reading.
From Page 44:
"The main difficulties reported by the pilots surveyed are:…
A reduction in their capacity to cope with the situation, resulting from the momentarily excessive workload induced by the speed at which the situation changes.
The problems associated with managing a thrust considered by the pilots to be excessive, since it causes very high levels of acceleration and/or vertical speed.
The rapid changes in configuration (flaps and landing gear), aggravated by the need to make new manual inputs (FCU/FCP), to check them (FMA, PFD), or even to engage certain automatic systems (FD, AP, A/THR).
The management of the automatic systems, under time pressures, when the goaround does not adhere closely to the intended procedure. In these cases, the automatic systems may no longer be of assistance to the pilot.
The breakdown of coordinated actions or teamwork in the cockpit.
The obligation, on certain aircraft, to select full thrust: Which may be excessive, when the stabilisation altitude is too close to the altitude at which the decision to go around was made; ....
Which induced disruptions relating to somatogravic illusions."
Present simulators don't realistically simulate the sense of acceleration you will feel in real life when you perform a light weight GA with TOGA thrust and GA attitude of 17 degrees or so. (due to constraints of the simulator leg geometry). Some crews are taken by surprise and suffer from somatogravic illusion.
Page140.
"Consequently, the BEA completes this recommendation in the context of this study and recommends that: ICAO ensure that manufacturers of simulators in cooperation with aircraft manufacturers improve simulator fidelity with respect to the phenomena of somatogravic illusions, especially during go-arounds. [Recommendation FRAN-2013-043]"
Page 121:
"Specifically, in case of a rapid increase in speed, they did not realise that it was better to reduce thrust manually, rather than to try to « understand ». "
Meanwhile I'll be ready to simply reduce thrust as necessary.
