Sorry, more AL Q's
 

Sorry everyone, more transponder stuff. I really can't find the definitive work. Would be very grateful for suggestions as to answers.

22. The radar controller suspects that you are experiencing unlawful interference. What should he do to confirm this with an auto detector unit? (With no mode A interpretation?)
a) Switch from 7700 to sby to test 7500
b) Switch from 7600 to 7700
c) Switch from 7500 to 7700
d) Switch from 7000 to 7500

23. If the aircraft cannot squawk ident, what directions can ATS give to the pilot without directing him to turn the aircraft?
a) Switch to on then standby
b) Switch on to off
c) Switch on to standby to off
d) ?????

23 is easy, must be standby. If you switch an older model transponder off then it won't be seen for a short while after switching back on again, I believe about 2 minutes (as you will find out if you accidentally knock the avionics master off while flying IFR!).

Hey friend!!

The answer to the ask 22 it is C) 7500 to 7700

I hope I will help you.

Thanks :ok:

66. Whenever unlawful interference with an aircraft is suspected, and where automatic distinct display of SSR mode A codes 7500 and 7700 is not provided, the radar controller shall attempt to verify his suspicion by setting the SSR decoder to what?


66. Mode A code 7500 and thereafter to code 7700.
