On VRG, you have to move the knob to the left, so a large passenger can 
dislodge the trimmer. The usual problem is that many people seem to carry their 
wallet or mobile in their left trouser pocket. I check for this before take-off 
as well as giving the "leg-stroking" warning.

  Strange.

  I think the most generous person might describe me as, um, 'well rounded'
  but I've never had this problem - I admit the trim handle is a bit close when
  I'm flying...

    Hi John,

    Does your trim have the gate on the right or the left of the knob?
    The gate in my aircraft requires the trim knob to be moved to the right to 
unlock it, thus a generously proportioned (must be careful with words here when 
referring to family members!!) person actually locks the trim rather firmly. 

    For a large legged person's thigh to cause the trim to become unlocked they 
would need to be seated in the left seat, which would be unusual unless the 
person was undergoing formal instruction.

    Further to Macka's incident with the cadet with huge thighs I recently had 
a lady passenger with very large thighs. When she got in she sort of flowed ( 
overflowed ) into position. It was not a weight problem just size.
    The flight went well and was quite pleasent and I do recall saying I was 
just adjusting the trim and not playing with her leg. The approach and landing 
went well until the final flair when the nose shot up and the canopy filled 
with sky. Immediate application of power brought the nose over and I was able 
to land nearly normally.
    I could not understand what had gone wrong untill the lady got out and I 
saw that the trim was in the rearmost position. Her thigh had held the trim 
lever out of the rack and when I flared it flew back causing heavy load on the 
control column, something I had not anticipated. If it was to happen again I 
would know to apply more pressure on the stick. Another lesson learnt.

    Regards, John.
