View Full Version : A320 protection
Alternate law - you may or may NOT have the high/low speed stability....what failures would inhibit these stabilities? Im guessing its something to do with the FACs?

hi,
Alternate law without speed stability may occurr if you lose AD,s,IR,s or control of both elevators.
source A320 Professional Pilots guide.page 171.

Good afternoon, Father!
Got mine in Transair Pilot shop.
Saucy expensive, 50 quid sterling, and have'nt read it much......
But glancing through it now, it looks pretty good.
243 pages.
Please get Mrs Doyle to make the tea...
You will, you will etc. !!!

My instructor had me print FCOM 1.27.30 p2 FLIGHT CONTROLS LAW RECONFIGURATION schematic. It is not an easy read especially because subsequent text pages use different names for the various regimes.
The way I read it is that in ALT LAW, you can never have all protections. Some are lost. ALT LAW - REDUCED PROT (schematics) = ALT LAW (text) load factor - available
pitch attitude - gone
low & high speed stability - available
bank - gone
ALT LAW - NO PROTECTION (schematics) = ALT LAW WITHOUT REDUCED PROTECTIONS (text) this in fact is understood as ALT LAW with even less protections than in REDUCED mode load factor - available
all others - gone
In which case your question may be answered by the left most branch of the schematics double ADR failure (2nd not self detected and/or speed/mach disagree)
triple ADR failure
duble SFCC slat channel fault
G+B HYD lost this would be called ALT LAW with NO PROTECTIONS albeit, obviously, the g-load prot is still available. :ugh:

n.b. A321 marked items on Ingos schematics are also applicable for A319.
