Chieftain Stuff

[Brown Cow]

For anyone who knows stuff about Chieftains, I'm just trying to work out some performance stuff. On a 30 degree day at MTOW in nil wind does about 450m sound right for take off distance? (sealed rwy)
Thanks in advance

Hi Brown,

I think you'd better check your charts again.
For your situation specified above:

Piper PA31 Navajo (wing lockers): 915 metres TODR to 50 feet @ SL
Piper PA31 Navajo (no wing lockers): 762 metres TODR to 50 feet @ SL

I haven't flown the Chieftain but wouldn't expect the distances to be less than the Navajo.
450m sounds more like a Light Seminole!

Hope that helps

Cheers

thanks mate, I didn't think my answer sounded right! Cheers

Cow,

I dusted off the old Cheep-tin manual and for nil wind, SL, 7000lb (MTOW) I get 1950' or about 650m.

I say if you can't get a chieftain off in 450m you're not trying hard enough.

Cheers,

Tiger.

I take it you've never flown a fully loaded Chieftain in 40 degree heat then Tiger??

i use to fly chieftains in and out of 700m strips and they were 'tight sphincter' moments if you did not have a good few knots on the nose. Never went out at MTOW , generally stuck to MLW as a max. It depends as all chieftains are are not the same , but they all perform badly :P

450 metres?

450 metres may work in some places, but in a central Australian summer you need to be looking for about 1250 metre strips for fully loaded chieftains,402's etc.
Two of the factors that are common in prangs are bad weather and bad airstrips.
Time spent with the takeoff charts is never wasted.

That definitely rings the bell from many years back
Every bloody Chieftan is different. Some were complete bow wows and this was when they were nearly new !
I once took a brand new one to the New Guinea highlands.Compared to a 402 it was a total dog until up until well into the climb
Be wary

Watched a Chieftain with a few blokes and full tanks take off from 1300m of seal a few weeks ago. It took him at least 900m to get it off the ground. Then it didn't want to climb. I believe that he had an acute interest in the trees near the upwind threshold.

450m was a long lost dream for that a/c and the day was better than ISA.

Just about everyone is as different as the next especially with so mod's avaliable for them.
Would have thought the 1040 would go alright tho i base that on no real knowledge of the thing other that it having a couple of PT6's(?)

[Brown Cow]

Thanks everyone for the good info. I'm just about to start a new job on cheiftains with out much previous experience on type, so any other tips or advice would be greatly appreciated.
Cheers

Chieftain Tip,

When you put pax in the last row, it blows the COG rearward so fast it isnt funny! Make sure you have plenty up front before using that seat!

Chieftain Tip #2

If there is still such a thing as a nose locker key lock, lock it with the key everytime.

[Shanty]

Chieftain tip #3

beware the right hand front seat passenger doesn`t nudge the fuel crossfeed to give you a bit of engine out practice.

Happened near Century a little while ago.

Chieftain tip #4

If you get a gentle roll on lowering full flap on final
You have a broken rear spar

[OpsNormal]

Chieftain Tip #5

And if you get a really big roll to one side after putting flap out, you've got a flap assymetry problem which may well take all of your available aileron to counter. There is a story I have heard about that happening, from memory right here in Oz.

Chieftain Tip #6

When approaching base, runway 11 in Darwin don't move the "condition levers" to low idle

Anyone ever seen a Navajo go in and out of a 512m strip... I have... Murray Island... never saw how many on board, and i believe it was STOL kitted, but none the less! Jeezus! Never liked the first 500 feet from take off in a pa31... never felt... quite right

Darnley is 505
