What you are suggesting is absolutely NO different to suggesting all PPLs carry and wear a parachute in a Cessna 150.
In the event of an engine failure
Pace I think that is chalk and cheese to what we are talking about and a ridiculous comparison.
1) So I have my family in a Cessna say 172 and we are all going to jump out taking 2-4 minutes at least, I do not think so.
2) The aircraft would be then a relatively high speed lump of debris randomly impacting anywhere full of fuel and likely to explode.
No I do not think anyone is suggesting that and it would be madness and no one is suggesting writing to the CAA with this as a viable alternative.
It appears a difficult concept using BRS for most pilots to accept because for ever they / we have been trained to land in a field as the only available option to them was to land in a field.
Most do not have BRS available to them so discard it as a gimmick or a cop out of being the captain in command.
In the Cirrus their is a choice and a viable alternative. Due to its higher stall speed (than most spam cans) and small wheels that are not very good off road creating a bigger chance of flipping and kart wheeling I prefer to a pre planned decision that unless I have a known or virtually guaranteed suitable landing surface I will use the chute.
This has nothing to do with what I or anyone else would choose to do in a non equipped BRS because they do not have the option.
