Hi All,
Yep, another stupid question, because I am trying to check my understanding and interpret rules and regs...
As some of you know from previous posts, I am flying D-Reg aircraft in Germany at the moment and have a UK Issued JAR-PPL. To keep safe all the advice I have been given is to look at the German and UK Regs and then abide by the most restrictive "profile".
So, here's the question I am looking at crossing the Alps, and have found/been advised of some easy-ish routes but they require short periods to pop up to FL115, to ensure cruise above MSA and compliance to Semi-Circular Rule. (FL100 to FL105 would be sufficient for MSA only)
From looking at the rules the most restrictive in this area are the UK Regs, O2 when between FL100 and FL130 for a period of 30 minutes or more. Which is ok, except for the investment in the O2 equipment. But is this 30 minutes, the total time above FL100 for the flight or each period above FL100... and if it is a period of time is there a recovery period below FL100 that you need before you are allowed back up without O2.
With all that said, looking at the flight planning I can do the first 45 minutes below 8000ft (so a low risk of hypoxia), then climb to FL95 for the first part of the alpine crossing, peaking at FL115 for about 5 to 10 minutes to cross the pass (total time above FL100 would be 20 to 25 minutes estimating climb performance), then returning to FL95 for about 30 minutes, before needing FL115 again for about a similar period to cross another line of hills; then for a nice long prolonged decent to sea-level (I can debate shock-cooling on the way down
).
Does anyone have a view if this would be legal?
Cheers
Jon
