"frequent" at https://infrastructure.gov.au/transport/security/aviation/asi/asics.aspx
from reg 6.01:
" operational need means:
(a) a requirement for frequent access to all or part of a secure area of an airport where persons are required to display an ASIC, for either of the following purposes:
(i) the operation of the airport or an aircraft;"
Kaz, I think you will find that the actual requirement has the word "frequent" in there."You need a valid ASIC if you require frequent access to a secure area of a security controlled airport ..."
While Moorabbin only required an ASIC to cross the blue line around the RPT operations I just had an AVID. Prior to a rare flight into Essendon (land,taxi without stopping then depart) their Ops Manager told me that I couldn't do it without an ASIC and I pointed out the rule that I did not need an ASIC due to the infrequent access required .... there is no provision for infrequent access.
I heard somewhere that the whole ASIC system was being reviewed with an intent being to make it work the way it used to be at Moorabbin. i.e. if one stayed away from the limited area of RPT ops then an ASIC would not be required.
Contact, I wish you had been around a few years ago to participate in a discussion on the instructors forum here. I got beaten up severely for making comments consistent with yours. I no longer have access to that forum so I'm unable to repeat my own comments here.
Tailplane dihedral gets it away from wake and efflux at high angles of attack.
Of course it also provides its own dihedral effect wrt spiral and Dutch roll stability modes.
Nope.
+4 is the limit load factor so permanent deformation will occur beyond that - just beyond it or some way beyond it depending on the type of structure and any additional margin (additional to that 1.5 ultimate factor).
How much built-up area may one fly over at 1,000 ft, unable to glide clear, before it is considered that one is "landing" as distinct from cruising towards an airport where one intends to land?I wonder how many pilots know what built-up area is?
I always take the law literally but sometimes I ask your advice.Per the old CAR it was permissible to undertake the review in a single seater and there was provision for a different aircraft to be used.
