Quiet welcome for plane (5)
I believe the answer is:
shave
'plane' is the definition.
('shave' can be a synonym of 'plane')
'quiet welcome' is the wordplay.
'quiet' becomes 'sh'.
'welcome' becomes 'ave' (I've seen this before).
'sh'+'ave'='SHAVE'
'for' is the link.
(Other definitions for shave that I've seen before include "Remove unwanted hair" , "Smooth surface" , "cut" , "Daily activity perhaps" , "Trim" .)
