VFR into IMC

[johnm]

A recent Dan Gryder Utube video;

 

A post / comment by an instructor;

 

interesting technique when in IMC by mistake / error or terror - no hands on yoke - just use your rudder for turns

 

........... for anyone to comment

I don't like it. Easy to check out with a qualified pilot beside you and you  under the hood.. You need a gyro instrument really, The normal compass has errors (turning and acceleration) that require a lot of practice with to use to keep a straight course OR do a gentle turn  The usual altimeter has Hysteresis and lags consequently. Better with an IVSI.  Nev

I think the technique described (in the OP) implies having a working AH and DG.

Partial panel would take the crisis to another level.

But yes, worth testing oneself out on, under qualified supervision.

IMHO, the method does have the benefit of simplicity - which may be key when panic threatens.

Wouldn't work with some planes that aren't spiral stable  You MUST roll the wings level with ailerons quickly. Nev.

I think the student pilot in the Dan video had done the 3? hours required for his PPL when he crashed. He was cross country solo standard. This would make a good video for RAAus student pilots as to why VMC must be avoided. I like Dan's videos because they show the human impact that these avoidable "accidents " have.

Everyone thinks they will always know which way "DOWN" is . Not so.  Nev

You read the comments on youtube videos?

Yes, I do ... with the same amount of discernment that I read comments on internet forums.

To dismiss all is as foolish as to accept all.

Quickest way to get into a death spiral; this idea is BS. If you have no turn coordinator altimeter vsi or appropriate training there's a fantastic chance nobody in the aircraft will be arriving home for mars bars; go try it on Xplane and see what happens. At least that way you can pick and choose the arrival scenery and season for the crash site...

I havnt got the time to filter through the rubbish, I just dont read them, nice back hander btw🤣

But which idea, exactly, are you saying is BS?  Nobody on here - or even the benighted YT Commenter - suggests anything to contradict "If you have no turn coordinator altimeter vsi or appropriate training there's a fantastic chance nobody in the aircraft will be arriving home"  Almost everyone in aviation holds to that idea; a truism.

 

That being the case, no one really needs to be marched off to an X-Plane sim to "see what happens"  (even absent panic and spatial disorientation).

 

The instructor quoted in the YouTube comment (in the OP) said this:

 

've always taught all of my students how to maintain control of the aircraft in IMC by performing the technique described by all Cessna operating handbooks for an emergency entry into the clouds. First, lower your power setting and re-trim. Next, and most important, keep your right hand on the throttle and LET GO OF THE YOKE and put your left hand in you lap. Until you're VMC again and can see, maintain your heading (and wings level) with your feet/rudders only. Any turns required are done with your feet only. If you require a climb or descent, it can be done by adding / reducing power only. You'll never lose control of the airplane like this. Get on the radio and declare an emergency and get help to find VFR weather.

 

So I for one (zero actual IMC/IFR) would be very open to hearing from those who know, about the problems with this long taught technique (for Cessna trainers, at least).  But, to be useful, it would have to offer an alternate method working from the same scenario.  That is: sudden inadvertent IMC; pilot with little/no experience in cloud; typical (Cessna) six-pack still working (IMC only just entered) and predictable Human Factors (like the urge to pull to save oneself) likely taking hold.  

 

Under those conditions what might a non-BS idea look like; a better long-shot on a sticky wicket than the one Cessna proposed for years.

 

 

BTW, was it not ATC's "hands-off" advice to the pilot in the famous "Mayday! Mayday! Mayday! I'm gonna crash!!!" affair, that was credited with saving his life.

 

FWIW there's an interesting review of that incident (and VFR>>IMC generally) in this video by airline pilot "74 Gear"

But for those with no time to waste gazing at the GoogTube (Red!!! I'm lookin' at you!  ; -)

you'll get the gist in less than a minute here:  20:23 >> 21:00

Reading that comment especially this sentence: 

Quote

Makes me suspect the commenter is likely not an instructor

Youtube Comments sections do seem to attract the Walter Mittys of this world

In Australia we are taught the secondary effect of controls.

The secondary effect of rudder is roll.

You're in the cloud, there's no horizon, you're in a slight turn so the G force has shifted off vertical - it now feels like you're straight and level, but then a wind gust lifts the inside wing.............

 

Also in Australia we have the Visual Flight Rules Guide which reminds us we don't follow the superseded rules any more - we must be clear of cloud and have 5000 metres forward view.

 

I haven't checked ATSB to see how this is working out, but I don't see that bunch of May fatalities we used to have.

There is a flaw in your statement ".... try it on Xplane ..."

There is no X plane.

Even I, a relativly inexperienced pilot, know that all aircraft do not have the same flight characteristics.

 

My GA traing was almost all Cessna  - they have incredibly stable flight characteristics. Trim for straight and level, hands  & feet off - thats what you get for hours. Change power they Climb/Descend straight ahead.

With the proviso you know where you are (not so hard in the era of GPS/moving map displays etc), unlikly to encounter ice,and know the cloud base/height, a controlled Climb/Descend, through cloud, in a Cessna 150-172 is not as challenging as many make out.

Unnerving Yes!  Do not try & control the aircraft, beyond initial setup and power change. Just let it do its thing and you will pop out above/below the cloud.

 

NOTE! I am not advocating VFR pilots, who find themselves contemplating entry to IMC, do this. Simply saying DO NOT PANNIK, consider your practical options. If in an inherently stable aircraft one option may be to enter cloud.

 

I now fly RAA - very different. Straight and level hands/feet off, is an aspiration that can not be achieved for more than a few moments. IMC (without competent auto pilot )in one of these little beauties would be challenging to the point of suicide.

IF you haven't done any In cloud flying then do some (under the hood. supervised ) and then return  to the conversation  My post above about not being able to tell  where DOWN  IS, is the crux of the matter. In a Basic simulator you don't experience the disorientating forces you do in  REAL situation.  If you have an autopilot use that. IT doesn't KNOW it's in cloud. Go into a COMPLETELY dark room and turn around about four  times. 

.   Recovery from a Spiral has to be quickly executed. (with ailerons)  because SPEED is building up fast and your instinct is to pull the stick back. Nev
