Club Events - Push-Ups for Pilots: Transit Trauma
An exercise in accurate flying, from Shoreham and Biggin Hill Briefing by: Tim Arnot.
  Briefing Friday 24th September 2010  
Start Time and Place From 7:30 pm local, on the main apron at Shoreham airport, or at the Cix clubhouse at Biggin Hill airport.
Staggered start times are preferred, so that everyone does not arrive back in the circuit at the same time
Departure and Duration We will depart and fly individually or in small groups. Each leg is approximately 35nm, and you are required to fly a minimum of two legs. Anticipate spending between 1 and 1 hours on this event.
Weather ...or not Before starting we will check the weather. If it is unsuitable for our trip as planned, then we will fix it. Something we can do in the simulator - wouldn't it be nice if we could do it in real life! For the general handling we need a cloud base that is at least 3000ft AGL.
FSInn has a "CAVOK" button. Click this and you get calm clear weather.
Those using SB will need to turn off the on-line weather updates, and select calm in the FS weather options.
Overview We will be operating a light aircraft shuttle between Biggin Hill and Shoreham, routing via Gatwick overhead. This will require a transit through Gatwick's Class D zone. As with all of our Push-Ups events, there is a significant training aspect to the flight, and emphasis this time is placed on airmanship, accuracy, lookout and comms under pressure. Aircraft will be starting from both Shoreham and Biggin Hill, so we can expect a lot of "traffic your 12 o'clock, similar altitude, reciprocal heading...". Hopefully the third 'A' - avoidance won't be necessary!

Pilots can start from either Shoreham or Biggin Hill, and will be required to make a full stop landing at the other airport, before returning to their starting aerodrome. Once you have arrived back at your start point and made a full stop landing, you can either commence another shuttle run, or practice circuits in various configurations.

Club members will find more information in the Events forum.
Flight Plan and PIREPs A Flight plan should be filed for each leg, and each leg should be PIREPped individually.

Biggin Hill to Shoreham:
Your flight plan should show: departure = EGKB, destination = EGKA, route = GATWICK ZONE TRANSIT, and comments = /V/ DAYLIGHT / CIX VFR CLUB

Shoreham to Biggin Hill:

Your flight plan should show: departure = EGKA, destination = EGKB, route = GATWICK ZONE TRANSIT, and comments = /V/ DAYLIGHT / CIX VFR CLUB

Airfield charts and information for UK are available from the AIS web site

Charts and Scenery

For preference, use photographic scenery covering the area. Part of the exercise will involve identifying your position using ground features. A variety of products are available for FS9 and FSX from Horizon Simulations and JustFlight.
An aeronautical chart that shows navigational aids (VORs/NDBs etc) in either 1:500000 or 1:250000 scale will be an advantage, or a reasonably detailed topolocical map.

GPS / Autopilot

Since this excercise is not a navigation test, use of GPS, Plan-G, waypoint discovery aids etc. for this event IS permitted. Use of Autopilot however, is NOT.

General

This event will take place under the London TMA. This imposes a 2500ft ceiling above which you may not fly (in practice, limit yourself to 2400ft). For the event, before you start, assign yourself an altitude (e.g. 2200ft, 2300ft, 2400ft etc), and try to maintain this altitude as closely as you can throughout. In addition, when trasiting through the Gatwick Ckass D zone, you will be under direct ATC control. ATC will assign you an altitude (e.g. 1500ft or 2000ft), and you will be required to maintain that altitude while in  the zone, without deviating from it.

After departing the circuit, climb enroute to your chosen altitude. Perform FREDA checks as required.

F uel Sufficient? Change tanks as necessary
R adio Correct frequency set? Standby frequency? Radio reports required?
E ngine Check Ts & Ps, ammeter and suction. Apply carb heat and check for icing
D irection Is the heading correct? Synchronise DI with magnetic compass
A ltitude Correct QNH/QFE set? Check altitude being flown

Shoreham to Biggin Hill Departure clearance will be given by ATC: Follow any instructions you are given. You will be departing the circuit to the North East. Climb to a suitable altitude.

As soon as is practicable, change frequency to Gatwick Director, and make contact. You are required to request transit clearance at least 5 minutes flight time from the zone boundary. Follow any instructtions that the controller gives you, but remember also to keep good lookout for other traffic - there will be aircraft coming in the opposite direction. The controller may well have limits on the number of aircraft he can handle in the zone at one time, so be prepared to hold if asked.

Your clearance will be from Handcross Roundabout to Reigate railway station. You will be asked to report entering the zone, overhead, and leaving the zone. Give a simple concise position report - "G-ABCD entering the zone". Remember the controller is busy, and doesn't have time for you to relate your life story.

Handcross roundabout is on the main A23 road, to the South of Crawley. It should be straightforward to spot, even in default scenery. Reigate station is in the middle of Reigate, at the base of the North Downs escarpnent, and South of the M25.

After leaving the zone, you will be clear to climb, bearing in mind the prevailing 2400ft restriction under the TMA. Circuit height for Biggin Hill is 1600ft on  the QNH. Contact Biggin Approach (or Thames, depending on who is online), as soon as you can, for joining instructions.

Once you have landed, taxi to the CIX hangar.

Biggin Hill to Shoreham Departure clearance will be given by ATC: Follow any instructions you are given. You will be departing the circuit to the South West. Climb to a suitable altitude.

As soon as is practicable, change frequency to Gatwick Director, and make contact. You are required to request transit clearance at least 5 minutes flight time from the zone boundary. Follow any instructtions that the controller gives you, but remember also to keep good lookout for other traffic - there will be aircraft coming in the opposite direction. The controller may well have limits on the number of aircraft he can handle in the zone at one time, so be prepared to hold if asked. Be aware of Redhill's ATZ, and make sure you do not stray into it.

Your clearance will be from Reigate railway station to Handcross Roundabout. You will be asked to report entering the zone, overhead, and leaving the zone. Give a simple concise position report - "G-ABCD entering the zone". Remember the controller is busy, and doesn't have time for you to relate your life story.

Handcross roundabout is on the main A23 road, to the South of Crawley. It should be straightforward to spot, even in default scenery. Reigate station is in the middle of Reigate, at the base of the North Downs escarpnent, and South of the M25.

After leaving the zone, you will be clear to climb, bearing in mind the prevailing 2400ft restriction under the TMA. The TMA steps up as you progress South, but there is little point in climbing above 2400ft unless you really  want to. Contact Shoreham ATC as soon as you can, for joining instructions.

Once you have landed, taxi to the main apron.
Circuits (optional) As with other push-ups, once the assignment is completed, there will be the opportunity to practice touch and gos in a number of configurations.
Some of the following circuit types may be inadvisable if the circuit is busy. You can always come back and practice them another time. Try to perform at least three of the following:

Normal circuits
Perform a touch and go with the aircraft in the normal landing configuration

Flapless circuits
* Perform a touch and go with reduced or no flaps set.
* Advise ATC when you call downwind that the approach will be with reduced or no flap.
* Your approach will be faster and shallower than with a normal landing, so you will need to extend your downwind leg slightly
* Landing speed is slightly higher (due to higher stalling speed), and landing roll will be longer

Glide Approach
* Perform a landing without power
* Advise ATC when you call downwind that you wish to make a glide approach. If the circuit is busy, ATC may decline the request.
* Turn base earlier than you would for a powered circuit.
* Reduce power to idle. Set carb heat to hot (if fitted). Trim for best glide speed
* Do not lower flap until you are assured of overshooting your aiming point
* Do not attempt to 'stretch the glide' by pitching the nose up if you are undershooting - GO AROUND!
* Do not hesitate to go around.

Bad Weather circuit
* Request permission from ATC to perform a bad weather circuit BEFORE commencing this procedure
* Fly overhead the runway in the landing direction at a height of 600ft AGL.
* Once overhead the upwind threshold, start a continuous level 15 (max) banked turn until downwind.
* You will fly the downwind leg lower and closer than usual, so be aware of visual perspective changes
* As you pass the runway threshold, start a timer for 20-30 seconds (depending on wind speed)
* After 20-30 seconds, start a continuous level 15 (max) banked turn until on final
* Do not start your final descent until you have a good view of the runway

Precautionary Landing
A precautionary landing involves a number of low passes of the landing area down to a height of 100ft AGL in order to inspect the area for obstacles and obstructions. The purpose is to facilitate landing in a field or other area when a medical, weather etc. emergency precludes landing at an airfield.
* Request permission from ATC to perform a precautionary landing procedure BEFORE commencing this procedure
* Establish the aircraft in 'slow safe cruise' configuration (e.g. 75 kts with one stage of flap) at 600ft agl.
* Approach the runway in the landing direction, descending to approximately 300ft AGL
* Fly the runway length at 300ft AGL, TO THE RIGHT of the runway. Visually inspect the runway for obstacles
* At the end of the runway, go around at bad weather circuit height (600ft AGL)
* Once satisfied that it is safe, make a second approach to 100ft AGL. Go around again at 600ft
* If satisfied that the area is suitable, make an approach and landing as per the bad weather circuit.

Forced Landing without power
* Request permission from ATC BEFORE commencing the procedure
* Climb to 2500ft overhead the airfield
* Reduce power to idle. Apply carb heat if fitted. Trim the aircraft for best glide
* Commence a glide descent to the runway, using either standard pattern, or constant aspect methods
* Make appropriate circuit calls
* Do not hesitate to go around if necessary

VOR Tracking

The Instrument Flight document in the Training section of the club web site contains a section on VORs and how to use them. If you are unsure how to track a VOR radial, download and have a look at this.
The document covers the use of NDB and DME for direction and distance measurements as well.

Radio Discipline

Take care not to let our Teamspeak chat cut across ATC. Stop any conversation immediately the R/T comes alive, then continue if "he wasn't talking to us". This is difficult because when transmitting on Teamspeak you can't hear the R/T. So be brief on Teamspeak, and be aware that ATC might be trying to get through. If anyone hears an R/T message which seems to be being ignored, just say "ATC is calling G-CIXN" if you have identified the callsign, or "ATC is calling us" which is a cue for everyone to be quiet on Teamspeak until ATC call again (which they will). Remember too that if asked to "Stand By" by ATC, you do not reply - not even "Roger", but simply wait until you are called again.
Remember also that there are several different ATC frequencies in use, and you may not be able to hear when communications are taking place. Make sure you have set and know how to use a Teamspeak mute switch.
