5200 the first hour??? I trust you and all but I was thinking more along the lines of 4500 first hour and 4000 there after. Atleast thats what they told us to go by un upgrade.
Personally I like 5000 first hour then 4000 after.
So we are 200lbs/hr different...not to shabby. Yeah...Climb to altitude...plus, you gotta remember its the NE Corridor---PHL ALOT (cough, cough), so I use alot of fudge. I look at the time to destination and plug in the numbers. That includes my alternate, too. Works well. Also, I look at FOD (Fuel over destination). My personal comfort level is min of 4000lbs FOD. RPA wants an average burn of 550 gph or 3690 lbs/hr. That's Block to Block and includes APU burn, SE taxi out and in...if able, and standard climb, cruise, decent, and approach. (Of course, we all know the NE Corridor is totally non-standard.) If you follow their profile in the computerized flightplan data, you get pretty close...except if you operate outta PHL...
By the way, with all this crappy weather in DFW regional this last 3 weeks, I had to divert to SHV and declare min fuel for the first time in this ship. Had yellow fuel numbers the last 15 minutes of the flight.
ATC was cool as we are one of six aircraft low on fuel, so they pretty much let us do what we wanted to get to our divert field.
