I have two problems with the PLB.
Number one is the up to 90 min for the satellite to see you and respond. If you are in the water off the UK, this is 30 min too long to be of any help at all.
The second is the registration. The unit must be registered to a mobile phone number and an aircraft reg. I had hoped that the flying club would buy two and hire them to members, but it does not look as if this is possible.
The bottleneck over the short crossing will now be even more of a problem, but it will still be legal to fly to France in the club spam can.
