Can vacuum AI be removed if a certified electric one is installed??
I had an interesting discussion with other pilots about converting my
Piper Cherokee 6 to all electric. This would basically require replacing the AI and DG with electric AI and elec. HSI. So, then, there would be no use for vacuum pump. But, one pilot said that the certified elec. AI only allows for installation of the unit, and that the FAA would *NOT* approve full removal of the vacuum instrument if it was delivered and certified with the aircraft. Any experiences on this? My goal would be to put an elec. AI and HSI in the panel, dump the two vacuum guages and also dump the vacuum pump (some weight savings!). Has anyone done this successfully? |
