How does the 'big effort' square with filing a flight plan in Class D and higher Class airspace from gate to gate, but voluntarily changing in flight to 'point to point' in Class E to save fuel?
Agreed universal ABSB fitment would make their life safer. If the airlines would put together a fund from their fuel saving to fit my glider with appropriate equipment, they are entirely welcome. Or why not just use the airspace provided for their exclusive use?
I fear that in the face of the money glider pilots will simply get forced out of the skies. GA in the form of much used SEP's will go next unless owners fork out the £20k or so required for an all encompassing collision avoidance system. Heavy metal will simply insist that their benefit to the economy is the greater need and that'll be it.
