it's not hard. all it takes is $75-150G's of loose change available to burn rather quickly. then you hire a consulting firm specialised in approaches to draw one up and with minimums tailored to your specific on board equipment and flight crew experience levels (and hope that the minimums are not so high that they're actually useful). then you submit about 50 pounds of paper adorned with letters, numbers and pictures arranged in nice color coordinated patters to the FAA, convince them that you've met all the requirements, fly it a few times with an approved FAA rep, and wallah! you (and your co-pilot) can now take your FLIR equipped G5 in at night.
