MPM and MPRT Flashcards
What is the base height for MRTs/MPRTs when dual and solo? What does this height indicate?
4000ft Dual
5000ft Solo
Height by which the MRT/MPRTs must have been completed, stall symptoms removed and normal g loading established
How far above cloud must you remain during the MRT/MPRT?
2000ft - take in to account for BH calcs
What AoA will you fly MRTs?
16 units AoA (in the stick shaker)
Flown level
How are attitude changes made during an MRT?
Adjusting AoB
What do the elevators control in an MRT?
Pitch rate, and therefore AoA, which in turn alters CL and hence the turn
What is the work cycle to maintain an MRT?
Lookout - Attitude - Alpha - Altimeter - Ball
And what speed and g will an MRT stabilise?
150-160 KIAS
2-2.5g
What power is an MRT/MPRT flown with?
Max
How do you enter an MRT from the stabilised speed (160 KIAS, approx. 38% TQ??)
‘Picture, Power, Pull’
Lookout (incl. TCAS)
Picture + max power simultaneously, rudder to balance
Pull to artificial buffet, refine for 16 units (LOOKOUT!)
Begin maintenance cycle
How do you enter an MRT from cruise speed (210 KIAS, approx. 56% TQ)?
Lookout, incl. TCAS
Simultaneously set picture (higher speed = more AoB) and power (max) - rudder to balance
Smoothly pull to 4.5g, squeeze to 5g or 16 units AoA, whichever occurs first
Speed will rapidly reduce, maintain 16 units and reduce AoB as speed decreases to stay level. Aircraft will eventually stabilise approx. 150 KIAS, maintain as before.
LOOKOUT through the top of the canopy throughout
How do you enter an MRT from 240 KIAS (80% TQ)?
Same as for 210 or any high speed MRT
What is the max g limit for practice MPRTs?
5g
How is speed controlled during an MPRT?
AoB
AoB used to control the attitude, and hence speed as the power is max so energy comes from height trade off
Why do you need some in to turn aileron during an MPRT?
Because the aircraft is descending rapidly with significant AoB, the relative airflow impinging on the lower wing creates a rolling moment which acts in the opposite direction to the turn, causing the nose to rise.
How do you enter an MPRT at the stabilised speed (210 KIAS, approx. 56% TQ)?
Lookout, right into the back and BELOW, dipping a wing will help (incl. TCAS)
Roll to 90 deg. AoB, simultaneously apply MAX power, rudder to balance.
Pull to 4.5g, squeeze to 5g, or artificial buffet, while allowing the nose to drop to approx. 15 deg. ND.
Keep the artificial buffet/16 units AoA and adjust ATTITUDE to maintain (lower = more g for 16 units AoA)
Adopt maintenance work cycle.
How do you enter an MPRT from below the stabilised speed (180 KIAS, approx. 45% TQ)?
Lookout, including below (wing dip, TCAS)
Roll to 90 deg. AoB, rudder to balance. Apply MAX power, pull to artificial buffet.
Allow nose to drop to 20-25 deg. ND.
Allow aircraft to accelerate, whilst maintaining the artificial buffet/16 units AoA.
Speed and g will increase. Increase back pressure to maintain the buffet.
Just BEFORE achieving 5g, adjust the attitude to the stabilised attitude (approx. 15 deg ND).
Keep the artificial buffet/16 units AoA and adjust the attitude to maintain 5g.
Fully established - Adopt maintenance work cycle
How do you enter an MPRT from above the stabilised speed (240 KIAS, approx. 80% TQ) and above?
Lookout, roll to 80 deg. AoB, MAX power, rudder to balance.
Pull to 4.5g, squeeze to 5g.
Entet a slight (2-3 deg.) climb to reduce airspeed.
At approx. 220 KIAS, overbank to lower nose to the normal MPRT attitude (approx. 15 deg. ND)
Stabilised 5g, 16 units AoA, adopt maintenance cycle.
How do you maintain an MPRT?
Lookout - Attitude - Alpha - G - Altimeter - Ball
Lookout through the top of the canopy to clear in to turn and below
What are the stabilised MPRT parameters?
Alpha - 16 units AoA (pull to)
G - 5g (AoB to adjust)
Attitude - Approx. 15 ND WL
Speed - Approx. 210 KIAS
Key is to establish and maintain 16 units AoA first and foremost.
What should you declare out loud during the descent in an MPRT?
Declare altitudes during the descent
Seven thousand, six thousand…
Maintain full SA of your proximity to the nominated base height.
How do you exit an MPRT?
Relax the back pressure to unload BEFORE rolling (asymmetric g limit of +4.7g)
Pitch to S&L or the climbing attitude as required.
Set power as required for the next phase of flight.
