Document IREX
Foreword（important）
For IREX exam, it’s more about the law. As you find and understand the rules, the next thing you need to do is just practice the questions. But unfortunately the IREX textbook talked too much into it.
This note is to help you save the time needed to collect all the references on the law & AIP etc., mainly provides you with the references you need for the IREX theory exam. You need to find, highlight and understand the subsequent sections by yourself. After that, just do the practice questions, and go back to the law, AIP! That’s all about the IREX exam.

Day IFR IAP or +500’ V8km for VAP
Night IFP must IAP
NVFR enroute 1 aid, otherwise ALTN WI 1h
Day IFR | Fly to AD without IAP/IAP that can’t use GAF LSALT for final route +500ft; V8km (It’s more strict than Day VFR, because Visual Approach Need to descend from LSALT, that’s why it’s IFR procedure, not VFR) |
Night IFR | Fly to AD without IAP/IAP that can’t use |
Night VFR | If ground aids/GNSS can’t be used to nav enroute to it: Nominate alternate within 1 h. |
C129 can’t use for alternate
135 MOS Ch11 11.09
135 IFR must 2 GNSS or GNSS+ADF/VOR; 135 NVFR must 1 Aid
Failure of any aid must able to continue, possible to IMC AD
Night VFR | Must have GNSS; or ADF/VOR | Barometric aiding must be connected if provided |
IFR | 2 approved GNSS[not C129] 1 approved GNSS and ADF/VOR [not C129 unless AC,GNSS installed before Feb 6, 2014] | |
Failure of any aid | Failure of any aid: can nav remained flight plan Can meet ATC, Airspace requirement | |
Possible to Land in IMC AD | Possible to Land in IMC AD: Nav to a point that can do Visual APP/IAP landing |
