Posted: Fri Feb 11, 2011 7:39 am Post subject: Icing Procedures

We’ve beat the heated pitot theory to death  - how about a topic twist to discuss the step by step procedures one will employ before and after encountering actual icing?  

   

My  RV-8A has a Gertz heated pitot tube and an AFS 3500 Angle of Attack (I’m a former Navy carrier pilot so I’ve be weaned on AOA stuff).  

   

Here’s my icing checklist – appreciate comments from those who think they have a better idea.  

   

<![if !supportLists]>1.       <![endif]>If pilot decides potential icing   

conditions exist,  or prior to entering   

clouds, or at very first sign of ice                              PIOT HEAT ON  

   

<![if !supportLists]>2.       <![endif]>AOA                                                                                       CHECK/VERIFY OPERATION  

   

<![if !supportLists]>3.       <![endif]>Indicated Airspeed/AOA                                              MONITOR/CORRELATE  

   

<![if !supportLists]>4.       <![endif]>At First Indication of Ice Accumulation                  CHANGE ALTITUDE AND/OR COURSE  

   

<![if !supportLists]>5.       <![endif]>Monitor AOA and IAS  

   

<![if !supportLists]>6.       <![endif]>If Icing Persists                                                                 LAND AS SOON AS PRACTICABLE  

   

<![if !supportLists]>7.       <![endif]>Enroute to Landing Site                                        CONTROLABILITY CHECK – (with sufficient altitude for stall/spin recovery)   

(slow at 10mph intervals to 100 mph, then 5 mph intervals to approach to stall)   

   

<![if !supportLists]>8.       <![endif]>Landing Pattern                                                        100 MPH OR AT LEAST +10 ABOVE APPROACH TO STALL  

   

<![if !supportLists]>9.       <![endif]>Established on Final                                               SLOW TO ENSURE SAFE LANDING ATTITUDE (my tailwheel’s on the front)  

   

NOTES:   

<![if !supportLists]>1.       <![endif]>Ice accumulation is dynamic, not static. Always be prepared for handling surprises.  

<![if !supportLists]>2.       <![endif]>Closely monitor handling qualities in the landing pattern; do not get slow  

<![if !supportLists]>3.       <![endif]>If stall buffet occurs in pattern, abort and increase pattern speed on next approach  

<![if !supportLists]>4.       <![endif]>DO NOT STALL IN THE LANDING PATTERN  

<![if !supportLists]>5.       <![endif]>Get the plane safely on deck – do not worry about landing style points

    All points offer due deference and diligence to the

    probability that a once comfortable and friendly machine

    may be suffering the effects of aerodynamic LSD.



    I would add a reminder that pre-stall buffet may be minimal

    to non-existent. The way the ice built on my personal

    spirit-walk with the ice demons had the effect of adding

    full length stall strip to the wing. It broke so quickly

    that if there was any pre-stall buffet, it was not

    noticeable.

In VFR weather a good pilot familiar with their craft should be able to

fly without an airspeed indicator. If you can't, you need more practice

to get the feel of your bird. Of course Navy pilots already know this.

Don't be so dependent on numbers.
