Really sorry to hear about your position FFF, although glad to see you back with us electronically.
On a pragmatic note:
I’ve spent most of this year coming to terms not only with the fact that I’m going to die, but also that I won’t be able to log pilot time again before that happens.
If you log into Cellma, and file a PMD, then so long as you are legal to drive, aren't on any psychiatric medication, and consider yourself fit to fly (possibly a challenge under chemotherapy, at least in the earlier parts of each cycle), you can fly subject to a few limitations: max 2000kg, max 3 pax, you can use an IMCR but not an IR, and you can use your FI but only for CRI level and NPPL instructing. It surprises me that this isn't better known.
If that doesn't work for you, fair enough, but you'd be very welcome to come up to White Waltham and get some air under the tyres in one of my Shareoplanes sometime.
