Hi,

 

Sorry if this seems daft but... should i be able to start the aircraft and make several touch and go's with these off? :doh:

Yes gravity will feed the engines but I believe you are recommended not to fly above 25,000 ft with inoperative fuel pumps.

 

Also can't be pulling negative Gs for obvious reasons.

Most aircraft has both mechanical and electrical fuelpumps.

The electrical ones are mainly meant as backup, but are on some aircraft also required above certain altitudes and when flying inverted.
