It is touch and go

Hi,

can anyone please explain the TNG bit of the following excerpt from a flightplan

AC#2,QA53,90%,24Hr,IFR,06:11,TNG06:32,070,R,0053,QAT1,06:34,07:00,070,R,0053,OTBD,08:41,TNG09:02,065,R,0053,QAT1,09:04,09:30,065,R,0053,OTBD,11:41,TNG12:02,060,R,0053,QAT1,12:04,12:30,060,R,0053,OTBD,14:21,TNG14:42,075,R,0053,QAT1,14:44,15:10,075,R,0053,OTBD

Just an example out of that line:

OTBD,14:21,TNG14:42,075,R,0053,QAT1,14:44,15:10,075,R,0053,OTBD

My take on it: - This aircraft leaves OTBD at 14:21 GMT each day, does something concerning TNGs, seems to end up at QAT1, then leaves there for OTBD at 14:44 GMT arriving at OTBD for 15:10.

Anyway right?

What happens around the time of the TNG?

Where does it do its TNG?

Any help would be appreciated.

OTBD,14:21,TNG14:42,075,R,0053,QAT1,14:44,15:10,075,R,0053,OTBD

Leaves OTBD at 14:21, arrives at QAT1 at 14:42, conducts IFR TNGs at QAT1 until 14:44 then heads back to OTBD arriving at 15:10. Flies at 7,500 both ways.

Thank you, Clickclickdoh.

That will be of great help to me when compiling flightplans for my local airport.

One further question though.

Differences between a VFR TNG and an IFR TNG?

Or does it matter?

[clickclickdoh]

IFR TNG will fly a 10 mile (I think, maybe 12) straight in approach and go missed from low altitude without touching the runway.

VFR TNG will fly a much shorter turning approach and will land on the runway, slow to 40 knots, then take off again.

I use VFR almost exclusively for helicopter AI to keep them from doing very long and slow approaches. VFR TNGs don't work very well at all with fast or large AI models because they can't make the turns required without overshooting badly. Also, VFR TNGs don't work well on short runways because of the distance required to land, slow to 40 knots then re-accelerate for takeoff. You will see lots of planes running off the end of the runway before flying again.

You explained something to me too clickclick, on most cases of my TNG's using VFR they didn't work so I just kept to IFR.
I did notice on Helicopters they almost went to a hover on approach, your explanation told me why, thank you.

Clickclickdoh, I now have no excuse for not having decent flightplans.
