Confirm (a) to (e) correct sequence.
Most folk find the whole process a test of endurance and determination - especially if you are trying to hold down a full time job. There are a number of thresholds to overcome and don't be surprised at doing a few of the elements or parts thereof - more than once.
Further order of events - one year down the line.
Renewal for MEP LAND/IR-SPA-ME is a combined annual 2-hour plus flying shakedown for which you will need to be totally current on procedural and GH aspects. Same standards as the initial IRT. Noticed more and more of US style oral examination entering the pre-flight and post-flight briefing with focus on technical questions - cross feeding, gear failures, engine fire procedures. Depending on the examiner - the renewal also includes more failures beyond just asymmetric flight that already lasts for about 1/4 to a 1/3 of the I/F element of the test. DME, RT, autopilot failures - then throw in de icing failures or simulated ice accreting faster than you can clear it - sometimes you wonder what next!
It's all achievable and probably less than a good line check and renewal on type with IRT that our commercial brethren undergo in the sim. (No smoke or really obscure systems failures!)
Expensive but totally safety focused and a good way of staying up to speed with the latest thinking.
Go for it.
