Performance tables for flexible take-off thrust missing on documentation
-
On the Fokker 28 there is 3 possibilities to set engines for takeoff:
- Full throttle (ok easy to set
) - Rated take-off thrust (P7 set take-off) > this one described on the tutorial and JF manual
- Flexible take-off thrust > who should be normally used on long runway and normal condition, and not possible to set because of missing performance information. Charts with take off distance depending of the TOW, OAT, pressure altitude and flaps setting is needed and missing.
- Full throttle (ok easy to set

Guess you need to get yourself a copy of a Flight Manual for the F28 to get all the info you need?
-
Ha, that is always the challenge, finding all the info you need from a copy of an operations manual.
-
Derated take off is calculated using the same tables for normal take off. Just select a row with temperature higher than current, and altitude according to current atm conditions, interpolate and set the index with that value.

@woolies it should be found on the Flight Handbook volume 2, but unfortunately impossible to get a copy.
If a former F28 pilot read this message, please share this golden manual

Google is your friend.

You'll need to keep looking for Mk 2000/3000 performance tables.

@piedmonitor Thanks for the link!
@papafox85 I hope you find your take off distance performance tables in that manual, good luck

You won't find the take off distance tables in that manual, there's a sample page but it would have been a separate booklet kept in the cockpit along with the speed cards.

@piedmonitor Thanks for the advise, won’t spend 48$ for nothing. The information is on the Flight Handbook volume 2. I have bought the volume 1 and training book for 10$, but unfortunately the volume 2 or 3 is not available.

Indeed. Tis a shame that the majority of the documentation for these old aircraft die with them when they get scrapped.
