That's me working in the cockpit at Richmond in 1991! I was replacing the ADI by the looks of it (the removed ADI is sitting on the ladder). The guy on the ladder was an interested RAN maintainer from memory.
Attitude director indicator or artificial Horizon: Ref. No. 967. SKYHAWK ADI. Indicator Altitude Director. Model 4060 BE. Spec: MIL-I-27619. Made by Lear Siegler Instrument Division, Grand Rapids, Michigan, USA. Measures 127 mm across by 133 mm high by 176 mm deep excluding knob. www.warbirdsite.com/museumskyhawk.html
Correct. It was seamless and unnerving when transitioning from Vampire era instruments. It seldom toppled under any circumstances unless U/S 'unserviceable'. IF it did topple then there was a warmup time when the red flags came out. I'll check NATOPS again.
Under the canvas hood in the trainer we would take off down the runway completely on instruments with the safety pilot in front keeping an eye on lineup but usually never a problem either.
Flying on it in the rear seat was like balancing on a slippery ball until one got used to it and relaxed. ;D

The ABBAJABBA was replaced with the Kahu upgrade to a "normal" ADI. There was a flight director bar for lateral steering commands which would give lateral guidance for navigation and attack steering. The attitude output of the ADI was used by the NAS (Nav Attack System) to validate the output of the Ring Laser Gyro, and if the roll or pitch varied by >10 degrees then ATTITUDE would be displayed in the HUD. If you ever saw this, it was always because the ADI couldn't keep up and the HUD attitude was correct.
I gather if we refer to the 1988 TA4K photo at Richmond with Don that the KAHU upgrade was not made so the panel would look like those below: There is the ABBAJABBA and the Standby Attitude Indicator - which one is an ADI? ;D OR is an ADI something different again for the KAHU?

See pic here of "new" ADI at Philip Treweek's great photo site:
The one located here: www.warbirdsite.com/museumskyhawk.html was only used as an example of an ADI as that is from a person or persons that is or has been trying to recreated a Kahu cockpit from spare parts.
I see the website has converted the .AVI now to a 3.3 Mb .FLV video so you can download either one. If you stream download the .FLV it will be in your browser cache for saving. Mine was called "X6" (3.3Mb) but if you copy and paste this mysterious file to somewhere on your file system it will be "rnzafABBAJABBA.flv". NeatOjet! as the Yanks would say. ;D

So who's is the rather large and impressive collection of A4 cockpit bits? Anyone know him, or am I missing the blatantly obvious (as usual)?
Perhaps they could help out when my far fetched plan to revive a T-Bird (and a model) comes to fruition.... This involves sacrificing virgins (nigh on impossible to come by in NZ these days, I hear) to the airplane gods and getting one for free before they get turned into coke cans. Doesn't need all those fancy Kahu electronic gizmos to perform succesive 50 ft beatups, just needs to be day VFR inside and look semi authentic.
Relax man - keywords are in order to-probably called wishful thinking.
Welcome to the A-4 Skyhawk page. In order to complete an A-4K cockpit under construction, I require a number of components. If you are able to assist, please contact me at Chris.....@......... If you have any of the following and wish to convert them to cash, I look forward to hearing from you. Thank you! www.warbirdsite.com/museumskyhawk.html
