IFR » IFR Flight Navigation » Flight Plan Preparation
IFR Flight Planning is the same as CPL Flight Planning only this time the legs with Tracks (in °M) and Distance are given on the enroute charts.
Just like a CPL flight log we must plan climb and descent.
The aircraft will pass through varying wind and temperature layers.
An average climb and descent point is needed to plan an average TAS, HDG and GS.
Climbing – average climb point is 2/3 of the climb.
Descent – ½ way down descent.

Flight Plan Details
Route:
- HK NDB - NS VOR - NP VOR - AA VOR - UKAPA - KT NDB
- Use the Approach chart for KT NDB/DME RWY 12
- ETD HK 0115 UTC
Climb:
Set heading from the HK NDB at 4000 ft and climb direct on track to FL190.
- CAS 140 kts
- Mean Rate of climb 1500 fpm
- Fuel flow 1680 lb/hr
Cruise:
- CAS 175 kt
- Fuel flow 1450 lb/hr
Descent:
Descent to Kaitaia is to be planned so as to arrive overhead the KT NDB at the minimum initial approach altitude for the NDB approach.
- CAS 200 kts
- Rate of descent 1500 fpm
- Fuel flow 1100 lb/hr
Diversion:
- Overshoot from MDA, then carry out a departure procedure to set heading overhead the KT NDB at 3000 ft.
- Proceed to AA VOR via UKAPA at 10,000 ft.
- Altitude overhead AA VOR is to be planned at the minimum initial approach altitude for the ILS approach.
- For planning purposes performance figures for the Climb, Cruise and Descent are to be used for the Diversion calculation.
- Use the Approach chart for AUCKLAND ILS/DME or LLZ/DME RWY 23L.
