Lookout, Attitude, Instruments

A method of maintaining a good Lookout whilst ensuring the aircraft maintain the desired altitude, heading and speed.  

LOOKOUT - This is completed in two stages, beginning with the Right hemisphere.  Look as deep into your 5 o’clock as you can and scan fully up and down whilst progressing you Lookout back to the ahead.  

ATTITUDE - Whilst looking ahead assess you aircraft‘s attitude to the horizon.  Ensure it remain where you desired.  

INSTRUMENTS - Check that this attitude is maintain your chosen flight path by checking the instruments:

• Attitude Indicator (AI) - Check the AI matches your attitude.  
• Altimeter - Either Barometric Altimeter (BarAlt) or Radar Altimeter (RadAlt) - Are you on height.
• Rate of Climb or Decent Indicator (RCDI) - Is it reading zero.
• Airspeed Indicator (ASI) - Are you on your chosen speed.  
• Horizontal Situation Indicator (HSI - Compass) - Are you on heading.

Limitation, Operation, Indication

A method of ensuring aircraft limitations are not exceeded when changing aircraft configuration.  

LIMITATION - Before operating any control that will change the configuration of the aircraft like the Flaps, check that the aircraft is within the limitations for that configuration change.  

OPERTION - Select the new configuration.  

INDICATION - Check that the configuration change has been successful by the control indicator.  

E.g. If the Landing Gear speed limitation is 175 kts the process is:

• Speed below 175
• Select Gear Down
• Gear Travelling .... Three Greens

Max Drift

A method of assessing the effect of wind on the aircraft drift from track.  

MAX DRIFT - The maximum drift an aircraft will suffer from a wind directly abeam the flight path.  This is estimated by taking the windspeed and dividing it by the aircraft’s speed in nm / minute.  

E.g. An aircraft flying at 240 kts is covering 4 nm / minute.  With a wind from directly abeam with a speed of 20 kts the aircraft will suffer a drift of 5˚.  

20 / 4 = 5

Navigation Exercise

A flight primarily aimed at exercising navigation skills

Progressively Adjust the Attitude and Trim

PROGRESSIVELY ADJUST the ATTITUDE - As an aircraft accelerates from a Climbing speed to a Straight and Level speed the lift initially generated by the initial attitude of attack increases as the speed increase.  If attention is not paid to this the aircraft will begin to climb.  The attitude will need to be progressively reduced as the speed increases.  

and TRIM - At each stage of attitude change the trim will need to be adjusted to ensure the aircraft maintain the new attitude with minimal input from you.  

Power, Attitude, Trim

A method of changing airspeed whilst maintaining level flight, or levelling off from a descent.  

POWER - Adjust the throttle to give the expected required power for the new Straight and Level speed.  

ATTITUDE - Adjust the aircraft in pitch to the expected attitude for that speed.  

TRIM - Trim any stick forces to a minimum so that the aircraft maintains the new attitude with minimal attention from you.  

Ramp Fuel

The minimum fuel required to be in the airbase overhead prior to landing, or on deck if landing on a vessel.  

Rate of Climb or Descent Indicator

A Variometer.  It is a barometer based instrument that has a controlled leak that allows it to measure vertical speed.

Select, Hold, Trim

A method of correcting small errors in attitude.

SELECT - Adjust the aircraft attitude slightly to minimise the error that is developing

HOLD - Hold this new attitude against any stick forces. 

TRIM - Adjust the relevant trim to minimise the stick forces so that the aircraft will stay on the new attitude with little attention from you.  

Start Up, Taxi, Take-off

Primarily referred to the fuel required to start up, taxi and take-off from the airfield to a point at which the climb is established.  

It can also refer to the time taken to get from start to established in the climb.  

Tactical Air Navigation, militärisches Funkfeuer, dem zivil genutzten VOR/DME ähnlich.

Eine boden- (oder luft-) basierte Navigationsbake, die die Anzeige von Peilung und Schrägentfernung zur Bake ermöglicht. Sie hat eine höhere Genauigkeit als VOR / DME.

Codes: 127

Bänder: 2 (X und Y)

Eine eingeschränkte Version von TACAN kann in Kampfflugzeugen implementiert werden und ermöglicht nur den Empfang von Entfernungsinformationen.

Vertical Speed Indicator

A Variometer, which is a barometer that has a controlled leak so that it measures rate of climb or descent.
